Day 31
"I have one last question, little slave," Vladimir Harkonnen drones from his afloat position, a celestial body of massive dimensions in front of the somber backdrop of his throne room, black within black with only a single glow globe illuminating the back of him. He prefers to shun the black sun these days, as glorious as it may be, it brings out the myriad of spider veins beneath his frail, aged skin.
"Yes, Lord Baron?" The unremarkable slave's voice echoes from below.
"What is this… ancient piece of metal in my dear nephew's toy's room?"
"I believe you must know more about it than I do. I assume you had it examined before it was unloaded and brought inside?"
"Naturally!" Vladimir raises his voice. The slave with her bowed head can't see the way the aged Baron squints to get a clearer picture of her. Afloat as he is, she is little more than a splotch of white against black, and an unwelcomely blurry one.
The examination had revealed a human shaped mold, cushioned with gel pads, thick tubes for coolant, a recycling system with residue nutrient solution, solar panels for energy harvesting. No traces of radiation or explosives. It almost seems like the metal box is exactly what the sisterhood had made it out to be. A hibernation chamber for a fossil from another time. However, it wouldn't be the first myth created by the Bene Gesserit.
"I know you are looking for something substantial, my Lord, and so was I," the slave speaks after the Baron's elongated pause. "But I'm afraid the truth is as embarrassing as it is mundane. I've come to believe that she keeps it close out of raw sentimentality. She's a sentimental creature, that woman."
Lilia has always loved danger and the long, twisted inkvine scar on her shoulder from girlhood days is just one proof of that. Perhaps that's why she so effortlessly serves the Baron velvet lies.
"Ah-h-h, like my Feyd-Rautha then. It doesn't surprise me," the Baron drawls, lungs expanding with a raspy heaviness to each intake of air.
In all his years as Giedi Prime's sovereign, Vladimir Harkonnen has never learned that the promise of a kind embrace outweighs the threat of violence tenfold and that a spark of human goodness can sway a servant's loyalty quicker than a snap of a whip.
"She calls it her sarcophagus," Lilia adds with a tiny scoff that doesn't go unnoticed by the Baron now that he has lowered himself and sinks back into the much more comfortable seat of his throne. The intimidation tactic has fulfilled its purpose.
He bellows. "So, she's got good humor too! A pity she's not a boy. I could have borrowed her sometimes."
The obedient set of Lilia's shoulders and her lowered gaze don't betray the noxious clench that has her stomach convulsing. Perhaps this is the only advantage of being a woman in the Harkonnen palace pyramid.
Tumblr media
Day 45
The lack of color that had once bothered her into the throes of a slowly crawling depression is now a pleasure. The blackness of her abode has come to serve as the perfect desktop for columns of text and equations, formulations and simulations and hand-written notes that have her mouth moving and her eyeballs racing.
Her sarcophagus leeches the day's sun, side panels open to give way to rotating cooling fans. The Central Processing Unit of the computer that makes up half of the machinery inside buzzes from the strain she puts on it.
Astronaut M2-84 has finally come home and picked up the work of her own, chosen destiny.
Talking to God, Mikhail had whispered to his wife, is what the Lady is doing. But what she really does is think, read, calculate. Engineers born on the cusp of the astronautic age don't have their oily hands in tool boxes. Most of the time, they tell machines how to build other machines, and to do so, one needs to understand the laws of physics. 
This is how Feyd-Rautha finds her each night. Sometimes sunken against the cushions of her bed, or slumped over her desk, staring at the wall with dancing pupils. And other times, like tonight, she sits right by her Sarcophagus, shoulder pressed against the humming metal. She claims the connection between computer and chip is quicker this way.
Silently, Feyd's stride carries him across the room towards his precious engineer. Movement catches his attention at the right and the sight he finds causes a slow tilt of his head.
One quarter of her bed is filled out by a misshapen form, tucked under duvet and whalefur. Glugo lies prone on its stomach, limbs folded tightly against its covered body. Only one front arm-leg peaks out and cradles her plushie against its innocent pug face. Something glossy-white with small handles on each side is held in front of Glugo's mouth by tiny face-hands with liquid sloshing inside.
She has tucked Glugo in like a toddler. And, from the looks of it, she has printed it a sippy cup.
Feyd-Rautha feels all sorts of warmth filling out his chest. If because he wants to be tucked in like a toddler, or because his only friend is finally receiving the gentleness it deserves, or because of a different reason entirely, he can't tell. He raises his hand to wave at Glugo who gurgles softly in return, one tiny face-hand unlatching from the cup handle to wave back.
Glug glug glug.
"You're losing weight." Feyd approaches his beloved slowly. "I don't like it."
"One second, I'm at ninety-eight point five. Seven. Ninety-nine."
"Have you found out anything interesting today, my darling?"
He is long past asking what exactly she's doing, why they aren't simply figuring out a way to get his uncle to take his shield ring off so they can get a blade between his ribs. Or rather a sword, to pierce the obscene, fatty flesh costume he calls his body.
"Your spice—" His darling slurs with a concerning jump to her pupils.
"I don't take spice anymore." Feyd tilts his head and squats down before her, lifting his hands to cup her cheeks.
"No, no, that's not what I meant. Ah, wait, what do you mean, not anymore?" Finally, her eyes regain focus and her arms fill with tension, fingers moving up to encircle Feyd-Rautha's strong wrists.
"There's my darling," he smiles with pretty, full lips and glinting teeth, stroking her cheeks. "So, what about my spice?"
"Not your spice in particular." Her hand flings out to gesture at the universe above. "Your spice shares a few molecular compounds with the medication I took to prepare for the cryo sleep." 
Feyd-Rautha's features slip into disbelief, a fresh frown carving deep into the smooth expanse of his forehead.
"Why does this surprise you?" She wonders.
"Spice is unique to Arrakis. Power over the spice means power over everything. How could you have had spice back on Earth without sandworms?"
"First of all, spice, much like anything else, is just protons, electrons and neutrons. With the right tools, you could, in theory, synthesize any molecule."
"And you have such a tool in your Sarcophagus?" 
"No! God, no." She laughs out loud and curls her arms around Feyd-Rautha's shoulders in a much needed embrace. Her very eyeballs ache and her spine feels calcified from leaning against the sarcophagus.
To him, it must seem like the solution to just about anything might be hidden in her cryo pod or in her precious chip, but it really holds only a fragment of the technological advancements of Old Earth. The last generation before mankind had embarked to the stars was an ingenious one. They had to be, and their knowledge is safely tucked into the 80 Billion terabyte hard-drive of her supercomputer. She may not have all the tools, but the knowledge to build them — in theory.
She taps the top of the cryo pod and hums. "Building molecules from scratch is not like building houses out of toy blocks. You need to accumulate tremendous amounts of energy in a lab environment to trigger complex chemical reactions."
"You've already built a chair from scratch, and a gun. And now a sippy cup for Glugo?" He states with an incredulous rasp of his voice.
"I couldn't bear seeing it drink from dog bowls anymore. And it struggled so much with cups and glasses, Lilia had to change the sheets twice because the poor thing kept spilling everything."
"You… You are fascinating, my darling." She doesn't miss the spark of arousal that lets Feyd's eyes half disappear under a fan of long lashes. "My point still stands, you've built other things before."
"Yes, but the materials were already there, I just had them pressed into the shape I desired." Feyd tilts his head and she cradles his jaw, stroking across the plushnes of his cheeks. "Were you not taught about chemistry?" Slowly, he shakes his head. "Ah, well, I will explain it to you another time then."
Feyd slides his mouth into her palm, groaning softly. "You know so much. How is it possible that you had spice 24 millenia ago?"
"Not spice. I said my pre-cryo medication shares a few interesting enzymes with spice." She slides one palm around Feyd-Rautha's nape of the neck and softly brings their foreheads together. "My people also used to think their own civilization was the pinnacle of all that has ever been. It was unthinkable that maybe the Aztecs or Sumerians were more advanced. That's how you are too. 
   You think spice is unique to Arrakis and the technological advancements you have derived from the Holtzman effect are the peak of what is achievable, because it suits you so nicely. But human evolution has never been a linear incline. You have fascinating medicine, Gholas and space travel��� But who knows, maybe my people were smarter than yours. Maybe our engineers and chemists were smarter."
"You know so much," he moans again and she knows better than to keep boring him with details. One day, when the many other fires in his heart have settled, she can stoke his interest in science. Feyd is smart. He will come to be fascinated by it. 
"This universe is devouring itself because there is no innovation," she softly murmurs. "No one dares to go further, look further, break out of the pattern. Maybe they don't want to, because the consequences scare them. Mentats only do as their Lords bid…"
When Feyd's lips close in on hers, with half-lidded eyes and a dreamy stare, her ramblings subside into grateful, blissful silence, choosing to welcome his tongue in her mouth instead.
Tumblr media
Day 59
"Silence!"
The Reverend Mother Gaius Helen Mohiam's voice ripples in the shape of a waveform pattern across the engineer's interface, recorded many decades ago by Baron Harkonnen himself and transferred to the House archive for research purposes.
Other lines of the same encounter, she is certain, were deliberately removed. Such as when the Reverend Mother, then a young woman, had ordered the Baron to hold still so she could mount him and steal the seed out of his body that would sire the Lady Jessica.
She only knows of this story because of Feyd-Rautha, and what it had cost him to learn it, she doesn't even want to know.
"Silence!"
She can only imagine that Piter de Vries' research on the matter might have consisted to a considerable amount of snide mockery, going by Feyd's recountings of the late mentat, hence why the files were so perfectly abandoned and ready for her to pick apart.
Carefully, she separates the impressive cluster of different wavelengths that make up the audio fragment, finding portions all the way from the high-frequency to the low-frequency audible spectrum, some even so low that they are no longer perceived as sound by the human ear.
The astronaut remembers how the Reverend Mother had tested her in an archaic show of deference, forced onto her knees with her hand in a box while the older woman addressed the pain receptors in her brain via an inaudible wavelength. She may not have moved her lips, but that doesn't mean she didn't cause the air molecules to oscillate.
Technically speaking, this renders the mysteriously omnipotent sisterhood into little more than ventriloquists. That image of demystification offers at least a little comfort to the humiliation provided by the memory of searing pain in every nerve.
She reclines in her chair, swallowing against the dry itch in her throat while she strings together a few fairly simple lines of code.
Curiously, the voice doesn't affect her physiology when played from an artificial source, such as the micro speaker soldered onto her chip's tiny board.
She can only assume that by manipulation of the larynx, wielders of the voice can propel pressure waves in a way that a speaker can not. How exactly this forces the human brain into submission, the engineer cannot tell, but she doesn't need to, to tinker on some offensively simple counter magic to the Bene Gesserit's seemingly almighty tool of control.
Noise cancellation is as simple as letting a speaker emit a sound wave with the same amplitude but an inverted phase. The sound waves cancel each other out in destructive interference.
As much as this scientific victory entices her, it frustrates her endlessly that all of the side research she picks up to take her mind off the real problem bears more fruit.
"Refreshments for you, my Lady!" Lilia's voice snaps her out of her brooding thoughts. The maid slips through the door, bringing a tray of fresh fruit and the stimulating citrus drink that her Lady has come to enjoy as of late. "It's been three hours, it's time to take a break."
"Ugh, three? Felt like one." That explains the dry throat. The relic arches her spine and presses her knuckles against her closed lids until tiny flashes prickle across the dark.
Lilia's footsteps close in at her side along with four other pairs of hand-feet. She sets the tray down on the desk.
"And have you made any progress today, my Lady?"
"Not with the one thing that matters, but yes." She reaches for the pitcher but finds her hands gently shooed away by Lilia who insists on pouring the glass for her, tiny bubbles fizzing in the lemon water.
"Oooh! Have you thought about these visions, my Lady?" The handmaid's ears perk up with interest, enamored with the story of how Feyd and her Lady had gotten to know each other in dreams ever since she had indulged her.
Lilia regards the phenomenon of their getting acquainted with the eyes of a romantic. For the engineer however, this is the only topic that frustrates her more than finding a workaround for the Holtzman effect to get past the Baron's shield.
"Dreams, visions, I don't fucking know. I don't even want to think about them because they drive me fucking crazy." The engineer reaches for her glass and drinks with big gulps, making the maid flinch by how forcefully she slams it back down.
The crescent shaped scar she herself had created on Feyd's clavicle when grappling for his blade is the same that had decorated his skin in their lucid dreams. So, visions? But the topics they had discussed during their shared nights are events of the past. It defies logic, it's paradox. The thing that scares her the most, however, is the fact that the Baron's abuse was still real in those dreams. If they truly were visions of the future, does that mean her research is in vain and he will live?
There is no phenomenon that can't be explained, not even prophetic dreams. But not by her, and not yet.
"Sorry," she apologizes and rubs her temples, finding Glugo staring at her with big, milky eyes, one hand-foot clinging to Lilia's skirt. The engineer's heart softens at once and she leans towards her insecure looking friend. "Aw, I'm really sorry, I didn't want to scare you both, my poor, little— Aw!"
Glugo curls four out of its eight limbs around her calves and rests its chin on her knee, pearly eyes aimed unerringly at the pitcher of sparkling drink on the desk.
"That's citrus," she explains. "I don't think you'll like citrus…"
One of the Tleilaxu creature's oily-black hand-feet clutches the table's edge, another incessantly reaches for the glass container.
"Okay, fine, but just a tiny sip. Where's your cup?"
Glugo glugs cluelessly, looking at Lilia for help. Still, both women are uncertain if the being has any grasp on human language, or if it simply recognizes a question by the inflection of one's voice. 
The handmaid locates Glugo's cup in the folds of the duvet and quickly washes out the remnants of pink liquid over the sink in the bath before filling a finger of citrus inside. The creature's hand-feet tippy-tap on the tiles, reaching for the shiny container to take its first curious gulp.
Glugo's pug face puckers into a scrunched up grimace at once, face-hands releasing the sippy cup with an indignant noise.
Glurgh!
Tumblr media
Day 93
It is a few weeks later, while Feyd and Mikhail are out brawling, that she figures it out.
"M'lord, I really am sorry," Mikhail laments, his flesh stripped of color as the black sun roars down on his bare torso. The na-Baron and he are prowling around each other in a tight circle, unarmed aside from their fists.
"You told me already." Feyd-Rautha's grating voice cuts through the sweltering air. The training ring's roof is retracted, giving way to blazing white skies and a heat that Giedi Prime's life forms have adapted to. "Five times. Another time, and I might just cut out your tongue."
"Ya know I had to take yer Lady to them bath chambers. Baron commanded it, and I can't just—" 
"Shut up, boy!" Feyd's boots crunch in the sandy gravel, shoulders rolling. He is stronger than Mikhail, rounded arms and pectorals contrasting a powerful, slender waist. The guard's physique is more wiry, taut muscles stretched across visible ribs. The glorious sun brings out an overabundance of gray scars.
"Boy, eh? Ain't any older than you, my Lord!" Feyd is surprised, tilting his head at the deceptive edges of the guard's features that make him look closer to 40.
"Fine, then shut up, brother!" Feyd bares his teeth and clenches his fists hard, veins rippling across his forearms. "What are the rules?" 
Mikhail's fist springs forward and punches Feyd-Rautha in the guts. He nearly doubles over, groaning in pain. Spit drips from his open mouth into the sand. 
"Rules?" The guard quips and aims his elbow for the na-Baron's nose. Feyd dodges with a semi-graceful dive to the side, taking the blow to his ear instead. He tastes blood on his tongue.
This man is bold. He has no manners. Feyd likes him. 
Mikhail is smaller, thinner, but he fights like a mongrel, like someone whose ferocious survival instincts have carried him from across the svart valta all the way to the royal palace in Barony. And Feyd struggles.
And by the black sun, he loses. Few things have ever excited him so much. After nearly an hour of grappling in the scorching heat, Feyd-Rautha finds himself on his back in the gravel, panting for dear life, ears ringing from the last punch square across his jaw. He barely hears Mikhail's voice when he praises that he had fought well, but he feels the brotherly smack on his sandy chest, right on top of a wicked bruise.
Every bone and muscle burns when he drags himself to his personal bath chambers. It was, undoubtedly, the best fight of Feyd-Rautha's life.
Tumblr media
"Lilia! I've got it! I fucking got it, do you see this?!"
Pixelated particles give way to a bullet that cuts through them like a harpoon through water.
"What, my Lady? See what?" The maid dashes into the bedroom from the antechamber with flying skirts.
"It's so simple, I'm so stupid." The relic has jumped up from the desk, fingers twisted like claws around the back of her chair while her chest heaves with laughter and a threat of tears. Lilia, of course, cannot see the baffling results of the simulation on the engineer's interface.
The Lady lurches over to the cryo pod, leaving the tilted chair swaying and falling down on the tiles with a bang. She mutters something along the lines of 'must build it', before her voice dissolves into foreign, ancient tongues and a shiver runs down Lilia's spine. Her voice so alien, her ways so enigmatic, she truly is a relic cracked open, pouring her forbidden knowledge into the world. 
But she is also a human and Lilia feels her Lady's voice and shaking body teetering on the edge of a nervous breakdown as she snaps open several compartments of the sarcophagus.
"You figured it out, that's wonderful!" This barely gets the engineer's attention, so she curls her fingers around the woman's shoulder, gently forcing her away from the compartments. The relic slumps down with her back to the sarcophagus.
"I need to build it. I know there's laser diodes in there, I only need to—"
"Please, my Lady, you need to breathe deeply. Why don't you explain it to me first?" Lilia squats in front of her, holding her wrists in her warm hands. Her Lady is trembling, her breath too shallow and fast.
"It's so simple, I could build it in an hour."
"Please, do me the favor," Lilia insists and brackets the woman's trembling knees between her own. Finally, her Lady exhales a long sigh and lets her head sink against the humming metal.
"Alright," she agrees and starts with a jittery voice. "So, you're aware of what the Holtzman effect is?"
"Ah, yes, I think so?" The maid hadn't really known the term before her Lady had started rambling about it. "Shields and heighliners?"
The one discovery that has shaped the entire human universe and kept it shackled since then, and the average commoner barely even knows its name. The relic doesn't hold it against Lilia. In a world where “eat or be eaten” takes on a literal meaning, the last thing to worry about is science. So, she wills her voice into calmness. If she's going to try and explain it, she at least wants to do it well.
"The Holtzman effect is responsible for the four major technologies that have made the world into what it is today. The first one — shields. No fast-moving object can pass through a shield, so guns like these?" She points towards her nightstand. "They've been useless for millennia. That's why you've resorted to close combat weapons."
"I was wondering why you went for a gun and not a blade." Lilia tilts her head. Close combat weapons are all that she's ever personally encountered. She knows that lasguns exist and that each Great House has an arsenal of atomic warheads, but every soldier has a sword on their hip, not a gun.
"Melee weapons seem so…" The engineer struggles to find a corresponding word in Galach. "Medieval to me. Archaic. Warfare on Earth was nothing like this."
"What was it like?" Lilia whispers in awe, noticing her Lady's shaking abate second by second.
"You could obliterate entire cities within the blink of an eye. A million different ways to set a home on fire and kill a population from a thousand miles away. It was terrible." Which is why what she has discovered is just as terrible.
The relic continues. "The other three technologies derived from the Holtzman effect are suspensors, glowglobes and space travel. You know why I was in that metal coffin here?" She taps against the sarcophagus. "Because a journey within our own solar system would take several years. You however can travel to the other side of the universe within the blink of an eye, through a quantum tunnel."
Lilia has never left the planet, but to imagine trade and travel without space-folding almost strikes her as ridiculous. All of humanity, reduced to just one, single planet. The cradle of mankind. The thought humbles her.
"And all four of these are based on one single effect?" Lilia considers herself an intelligent woman, but she doubts she can understand what took her Lady weeks to figure out.
"The essence of the Holtzman effect lies in how subatomic particles interact with each other."
"Subatomic?"
"Any type of matter is made of smaller building blocks. This metal for example is made of all kinds of molecules, which are made of atoms, and every single atom is made of protons, electrons and neutrons. These are called subatomic particles. Protons and neutrons make up the nucleus of an atom, and you can imagine the electrons orbiting the nucleus almost like planets a sun."
The handmaid quite enjoys that mental image. It's like the smallest particles exist in a cosmos of their own. "So, the Holtzman effect has something to do with protons, electrons and neutrons?" Lilia imagines, if she could have gone to school like she wanted as a girl, it may have been something like this.
"Almost. It gets even smaller. Protons and neutrons are made of quarks, tiniest quantities that cannot be divided any further. I could go into more detail and talk about quantum physics," the relic pronounces a word that is just guttural enough for Lilia to imitate without all too many struggles. "But that won't be necessary for now."
Even though her Lady has stopped shaking, Lilia doesn't want to release her wrists yet. She is glued to the engineer's lips, soaking up what sounds like forbidden knowledge, like having a peek through God's microscope.
"What is a Holtzman shield made of? What do you think?" The engineer wraps her own fingers around Lilia's slender wrists and the maid sinks from squatting on her soles to sitting down on her bum, stretching out her legs on either side of her Lady's.
"I don't know, my Lady. Uh, something that repels?"
"Yes, that's right," she nods encouragingly. "There are several forces in the universe that attract and repel. The most well-known force of attraction is gravity. And electro-magnetism— Opposite poles attract, equal poles repel each other. But there are other forces that work on a subatomic level."
The engineer pauses without urging her and Lilia takes a moment to think.
"I'm guessing there's a subatomic force that keeps these, uh, nuclei together? The protons and neutrons? Because if not, everything would just be falling apart?"
It almost frightens her to imagine what her very own body must look like on its deepest level. A cluster of tiniest quantities, held together by forces as invisible as her Lady's interface.
"That's perfectly true!" The woman from Old Earth beams, fingers clenching around Lilia's wrists. "The force responsible for that is called the strong nuclear force. On an even smaller scale, the strong force holds together the quarks that make up the neutrons and protons, but you already said it just right."
Warmth fills out the handmaid's chest and she slowly begins to understand the feeling that had her Lady nearly panicking earlier. Her own heart drums against her ribs quick and hard.
"Okay, so now what about the Holtzman shield and how can you get past it?"
"For that, we also need to take the other subatomic force into consideration. It's called the weak force. Isn't that creative? Despite its name, the weak force is technically stronger than gravity, but it is only effective at very short distances and it can change one quark type into another. What do you think happens when such a change occurs?"
"Hmmm," the Harkonnen woman ponders. She doesn't want to disappoint her Lady who is putting so much effort into her explanation. "If quarks are the smallest quantities that make up anything, I suppose when something changes on the lowest level, this change translates to the highest level as well?"
"You're a natural, Lilia." Upon that, the maid blushes purple and finally releases the relic's wrist in a sudden burst of shyness. "Such a change can turn one element into another. It happens all the time, in every sun. And also in radioactive decay. This is important."
"How so?"
"Imagine if that radioactive decay was amplified. Imagine throwing a huge amount of energy at a substance that is already sporadically decaying. Imagine a whole chain reaction of it. This is what triggers a nuclear explosion, the kind that obliterates an entire city."
Lilia's eyes grow wide with understanding. "So, that's why, when you shoot a lasgun at a Holtzman shield, it triggers a nuclear explosion?"
"That's right. I believe shields are made up of nuclei and rely on both the strong and the weak force to repel incoming objects on a subatomic level."
"All of that was fascinating, but how does it help us get past the shield?" Suddenly it's us, not you. Lilia has clutched the fabric of the relic's trousers over the knees in both of her fists. What the engineer's poor Feyd-Rautha currently lacks in fascination, Lilia makes up for a hundredfold.
"Oh, that was just the prelude." The engineer's lips twist into an almost mischievous little grin. "It's just what I need to take into consideration, so I don't accidentally blow up the shield and the city instead of passing through it."
"Just the prelude? My Lady, I think I'll go insane if you don't get to the point!"
The relic bursts out laughing. "We're almost done, I promise! Imagine you're riding in a groundcar and next to you drives another one with the exact same speed. When you look at it, it seems like you're both standing still, because the relative speed between both cars is zero." Lilia nods and the engineer smiles knowingly. "Now imagine you're a bullet and you want to pass through a Holtzman shield which only allows slow-moving objects to pass."
"Then I'd need the shield particles to move in the same direction as I do, only a tad slower, so that my relative speed is like that of a slow blade."
"Congratulations, you've just figured out how to trick a Holtzman shield."
"That is absolutely genius, my Lady."
"No, it's actually so simple." The woman shakes her head. "The difficult part is how to put the shield particles into motion, but I've figured something out." She summons the pixelated particles that are only for herself to see once more, nuclei that make up a Holtzman shield, accelerated by a burst of calibrated laser light, and how they give way to a bullet that cuts through them like a harpoon through water.
"Now I only need to build a proper gun," the engineer concludes.
Lilia has never cared much about the rest of the universe, and the universe has never cared much about her. Why would she care if her Lady, who has always been good to her, sets everything on fire?

"I've found a way!" She sobs.
"You've found a way?"
Tears spill down her cheeks as she nods, bringing her forehead against his. She's found a way. To kill the Baron and destroy the universe.
She is so elated, her joy could make a star rotate, it could set the world on fire. She kisses Feyd hard on the lips, melting against the wet expanse of his chest when he embraces her in his strong arms. His muscles break into tremors just like hers had an hour ago.

I'm not even close to the level of genius that I admire in my favorite sci-fi authors, but all of this was so insanely much fun to come up with. I have more ramblings about space travel, suspenders and glowglobes, but they weren't really necessary for this chapter. I hope you enjoyed this as much as I did. I'm very proud ❤️

By now, it has become an agonizing cliche that any amount of work on a modern car will terminate in you losing at least one 10-millimetre socket. "Oh no, my 10mm is missing," you'll groan to your friends, who immediately respond with haw-haw looks and jokes. Being the butt of such a horrible stereotype is far worse than losing your socket, which is itself a pretty bad day at work.
There are many techniques that don't work. I myself often write with a Sharpie on the socket "9.5mm," in the hope that it will confuse the curse enough that they will not be lost. I buy ones in weird colours. I use a giant neodymium magnet on the fender so they can't roll away and into the mouth of a nearby blower motor. Nothing works.
Official Chinese government numbers indicate that nearly 60% of the cars their metal recyclers crush, by weight, are 10-millimetre sockets. Your entire washer and dryer set is probably made out of the stuff that fell out of my pockets last year when I was trying to yank an evap solenoid.
Of course, there's a real solution too, and it just happens to be the same kind of solution that capitalism always presents. Buy a whole shitload of 10mms and walk into the junkyard jingling. You can lose a ton of them and not even care, as long as you have one left. This is an appealing vision, to be certain. Everyone wants to Be Prepared... but what happens when the curse moves on to your 12mm, something that is needed nearly as often?
Our scientists, with the help of a psychic that we found all by herself in a completely abandoned shopping mall, have determined an even better fix. We arm one volunteer with a chain-mail coat made entirely of ten-millimetre sockets, and walk their ass into the junkyard. They don't do any wrenching, which would cause them to lose their bounty. All they do is walk around, and when they see someone in crisis, break a socket off and hand it to the stricken victim.
There is a downside: any volunteer who does this is struck with so much positive karma that they start getting a little loopy, and create their own death cult right in the middle of the yard. To keep this from happening again, we have to regularly rotate out the volunteers, and put duct tape over their mouths so they can't start spouting the Good Word until a team of engine-pulling weirdos begin to kill in their name. I admit that the system is a little bit unorthodox, but I've never gotten parts pulled faster.

A new report by environmental groups lays out a case for banning deep sea mining—and explains why the real solution to humanity’s energy crisis might just be sitting in the trash.
Deep sea mining is the pursuit of rare, valuable minerals that lie undisturbed upon the ocean floor—metals like nickel, cobalt, lithium, and rare earth elements. These so-called critical minerals are instrumental in the manufacture of everything from electric vehicle batteries and MRI machines to laptops and disposable vape cartridges—including, crucially, much of what’s needed to transition away from fossil fuels. Political leaders and the companies eager to dredge up critical minerals from the seafloor tend to focus on the feel-good, climate-friendly uses of the minerals, like EV batteries and solar panels. They’ll proclaim that the metals on the deep seafloor are an abundant resource that could help usher in a new golden age of renewable energy technology.
But deep sea mining has also been roundly criticized by environmentalists and scientists, who caution that the practice (which has not yet kicked off in earnest) could create a uniquely terrible environmental travesty and annihilate one of the most remote and least understood ecosystems on the planet.
There has been a wave of backlash from environmentalists, scientists, and even comedians like John Oliver, who devoted a recent segment of Last Week Tonight to lambasting deep sea mining. Some companies that use these materials in their products—Volvo, Volkswagen, BMW, and Rivian among them—have come out against deep sea mining and pledged not to use any metals that come from those abyssal operations. (Some prominent companies have done the exact opposite; last week, Tesla shareholders voted against a moratorium on using minerals sourced from deep sea mining.)
Even if you can wave away that ecological threat, mining the sea might simply be wholly unnecessary if the goal is to bring about a new era of global renewable energy. A new report, aptly titled “We Don’t Need Deep-Sea Mining,” aims to lay out why.
The report is a collaboration between the advocacy group US PIRG, Environment America Policy Center, and the nonprofit think tank Frontier Group. Nathan Proctor, senior director of the Campaign for the Right to Repair at PIRG and one of the authors of the new report, says the solution to sourcing these materials should be blindingly obvious. There are critical minerals all around us that don’t require diving deep into the sea. You’re probably holding some right now—they’re in nearly all our devices, including the billions of pounds of them sitting in the dump.
The secret to saving the deep sea, Proctor says, is to prioritize systems that focus on the materials we already have—establishing right to repair laws, improving recycling capabilities, and rethinking how we use tech after the end of its useful life cycle. These are all systems we have in place now that don’t require tearing up new lands thousands of feet below the ocean.
“We don't need to mine the deep sea,” Proctor reiterates. “It's about the dumbest way to get these materials. There's way better ways to address the needs for those metals like cobalt, nickel, copper, and the rest.”
Into the Abyss
Schemes for delving into the deep ocean have been on the boards for years. While the practice is not currently underway, mining companies are getting ready to dive in as soon as they can.
In January 2024, the Norwegian Parliament opened up its waters to companies looking to mine resources. The Metals Company is a Canadian mining operation that has been at the forefront of attempts to mine in the Pacific Ocean’s Clarion-Clipperton Zone (CCZ)—an area of seabed that spans 3,100 miles between Mexico and Hawaii.
The proposed mining in the CCZ has gotten the most attention lately because the Metals Company secured rights to access key areas of the CCZ for mining in 2022, and its efforts are ramping up. The process involves gathering critical minerals from small rock-like formations called polymetallic nodules. Billions of these nodules rest along the seabed, seemingly sitting there ripe for the taking (if you can get down to them). The plan—one put forth by several mining companies, anyway—is to scrape the ocean floor with deep sea trawling systems and bring these nodules to the surface, where they can be broken down to extract the shiny special metals inside. Environmentalists say this poses a host of ecological problems for everything that lives in the vicinity.
Gerard Barron, the CEO of the Metals Company, contends that his efforts are misunderstood by activists and the media (especially, say, John Oliver).
“We're committed to circularity,” Barron says. “We have to drive towards circularity. We have to stop extracting from our planet. But the question is, how can you recycle what you don’t have?”
Both Barron and the authors of the activist report acknowledge that there aren’t perfect means of resource extraction anywhere—and there’s always going to be some environmental toll. Barron argues that it is better for this toll to play out in one of the most remote parts of the ocean.
“No matter what, you will be disrupting an ecosystem,” says Kelsey Lamp, ocean campaign director with the Environment America Research and Policy Center and an author of the report. “This is an ecosystem that evolved over millions of years without light, without human noise, and with incredibly clear water. If you disrupt it, the likelihood of it coming back is pretty low.”
For many of the life-forms down in the great deep, the nodules are the ecosystem. Removing the nodules from the seabed would remove all the life attached to them.
“This is a very disruptive process with ecosystems that may never recover,” says Tony Dutzik, associate director and senior policy analyst at the nonprofit think tank Frontier Group and another author of the report. “This is a great wilderness that is linked to the health of the ocean at large and that has wonders that we’re barely even beginning to recognize what they are.”
Barron counters that the life in the abyssal zone is less abundant than in an ecosystem like rainforests in Indonesia, where a great deal of nickel mines operate—although scientists discovered 5,000 new species in the CCZ in 2023 alone. He considers that the lesser of two evils.
“At the end of the day, it's not that easy,” You can't just say no to something. If you say no to this, you're saying yes to something else.”
The Circular Economy
Barron and others make the case that this ecosystem disruption is the only way to access the minerals needed to fuel the clean-tech revolution, and is therefore worth the cost in the long run. But Proctor and the others behind the report aren't convinced. They say that without fully investing in a circular economy that thinks more carefully about the resources we use, we will continue to burn through the minerals needed for renewable tech the same way we've burned through fossil fuels.
“I just had this initial reaction when I heard about deep sea mining,” Proctor says. “Like, ‘Oh, really? You want to strip mine the ocean floor to build electronic devices that manufacturers say we should all throw away?’”
While mining companies may wax poetic about using critical minerals for building clean tech, there's no guarantee that's where the minerals will actually wind up. They are also commonly used in much more consumer-facing devices, like phones, laptops, headphones, and those aforementioned disposable vape cartridges. Many of these devices are not designed to be long lasting, or repairable. In many cases, big companies like Apple and Microsoft have actively lobbied to make repairing their devices more difficult, all but guaranteeing more of them will end up in the landfill.
“I spend every day throwing my hands up in frustration by just how much disposable, unfixable, ridiculous electronics are being shoveled on people with active measures to prevent them from being able to reuse them,” Proctor says. “If these are really critical materials, why are they ending up in stuff that we're told is instantly trash?”
The report aims to position critical minerals in products and e-waste as an “abundant domestic resource.” The way to tap into that is to recommit to the old mantra of reduce, reuse, recycle—with a couple of additions. The report adds the concept of repairing and reimagining products to the list, calling them the five Rs. It calls for making active efforts to extend product lifetimes and invest in “second life” opportunities for tech like solar panels and battery recycling that have reached the end of their useful lifespan. (EV batteries used to be difficult to recycle, but more cutting-edge battery materials can often work just as well as new ones, if you recycle them right.)
Treasures in the Trash
The problem is thinking of these deep sea rocks in the same framework of fossil fuels. What may seem like an abundant resource now is going to feel much more finite later.
“There is a little bit of the irony, right, that we think it's easier to go out and mine and potentially destroy one of the most mysterious remote wildernesses left on this planet just to get more of the metals we're throwing in the trash every day,” Lamp says.
And in the trash is where the resources remain. Electronics manufacturing is growing five times faster than e-waste recycling, so without investment to disassemble those products for their critical bits, all the metals will go to waste. Like deep sea mining, the infrastructure needed to make this a worthwhile path forward will be tremendous, but committing to it means sourcing critical minerals from places nearby, and reducing some waste in the process.
Barron says he isn't convinced these efforts will be enough. “We need to do all of that,” Barron says, “You know, it's not one or the other. We have to do all of that, but what we have to do is slow down destroying those tropical rainforests.” He adds, “If you take a vote against ocean metals, it is a vote for something else. And that something else is what we’ve got right now.”
Proctor argues that commonsense measures, implemented broadly and forcefully across society to further the goal of creating a circular economy, including energy transition minerals, will ultimately reduce the need for all forms of extraction, including land and deep-sea mining.
“We built this system that knows how to do one thing, which is take stuff out of the earth, put it into products and sell them, and then plug our ears and forget that they exist,” Proctor says. “That’s not the reality we live in. The sooner that we can disentangle that kind of paradigm from the way we think about consumption and industrial policy the better, because we're going to kill everybody with that kind of thinking.”
Just like mining the deep sea, investing in a circular economy is not going to be an easy task. There is an allure of deep sea mining when it is presented as a one-stop shop for all the materials needed for the great energy transition. But as the authors of the report contend, the idea of exploiting a vast deposit of resources is the same relationship society has had with fossil fuels—they’re seemingly abundant resources ripe for the picking, but also they are ultimately finite.
“If we treat these things as disposable, as we have, we’re going to need to continually refill that bucket,” Dutzik says. “If we can build an economy in which we’re getting the most out of every bit of what we mine, reusing things when we can, and then recycling the material at the end of their lives, we can get off of that infinite extraction treadmill that we’ve been on for a really long time.”

About Nucear Permanent Disposal Sites
Tumblr media
So, a couple of days ago someone commented under my one blog about nuclear energy what boiled down to: "But what about the waste? We need to take responsibility for the next thousands of years of humanity!" And yes, that is very much the favorite argument for the anti-nuclear lobby... and it is pretty much based on the science of the 1980s.
What a lot of people do not understand is:
How little nuclear waste we actually have.
How little of that waste is actually the highly radiating stuff.
How well we can contain this stuff.
That we actually have figured out a solution for permanent disposal.
Tumblr media
First need about nuclear waste you have to understand that most of it is not that dangerous. Most of the waste we get out of the nuclear facilities is actually just stuff that was around the radiation and got slightly radiated. 90% of all nuclear waste is stuff like items that just happened to be within the nuclear facilities for a long while. Tools, wortk clothing and so on. This stuff radiates, yes, but it is technically not dangerous levels AND it will stop doing so within 100 years max. We literally do not need to worry about it. Those yellow barrels you will keep seeing in old media that somehow end up mutating people? Yeah, those are used for this kind of waste. And to be quite frank, we are super extra that we store this either way. Because we have waste from other types of facilities (like coal power, but also from places like airport) where this kinda waste also happens and we... just throw it away normally.
Then there is about 7% of nuclear waste that is a bit more radiated. This is mostly metal parts and such that were in direct contact with the nuclear elements. This gets more radiated and as such will radiate for a longer time. But, this, too, is radation that will be gone or down to safe levels within a few centuries.
Only 3% is waste, that is high-level radiating and even from this not all will radiate for millennia! In fact we have gotten real good with recycling this high-level waste and if we are now talking SciFi scenarios like Solarpunk, we could actually just switch to thorium based reactors, where almost all of it is recyclable.
But... Even with the high level radiating stuff that we cannot recycle and need to permanently store, we... actually long have a solution for it.
Tumblr media
You have to realize that those fuel cells are actually pretty small. And that we have materials that can basically protect you from the radiation. So, we basically just take those small spend fuel cells, put them into glass, put that into several layers of metal, put all of that into a deep, deep hole the ground and then fill everything up with clay. And... done.
Chances are: Nobody is gonna find it. Because it is gonna be so deep underground. Even if they did: It is protected enough that nobody is gonna die of radiation poisoning directly. Not only that: But the best rock material to burry this stuff in, is already radiating. So... Like, duh. We already have super radiactive stuff in nature.
And even if someone got radiation poisoning... Unless you suppose that humans of the future are dumber than most animals... They will learn: "Dude died. Area bad. Do not dig there."
Scientifically speaking... The entire nuclear waste thing is such a fucking non-issue, that keeps getting pushed up mostly by fossil fuels (that, again, also produce radiating waste!) to keep folks from going for a full renewable + nuclear energy mix. Aka: The clean option.
The reason why so many politicians do not just agree to those disposal options is that a) they do not understand it themselves and b) nor do their constituents and there is sooooo much fearmongering about this going on.
Again, I am not saying that we should go full nuclear energy. But rather for an energy mix of renewables and nuclear. Be CO2 neutral. Because I can tell you one thing: If we do not do that, there are not gonna be humans in 3023 we have to worry about. Because they are all fucking dead, with the planet being inhospitable to life.

Excerpt from this story from Mother Jones:
The world generates more than 68 million tons of e-waste every year, according to the UN, enough to fill a convoy of trucks stretching right around the equator. By 2030, the total is projected to reach 75 million tons.
Only 22 percent of that e-waste is collected and recycled, the UN estimates. The rest is dumped, burned, or forgotten—particularly in rich countries, where most people have no convenient way to get rid of their old Samsung Galaxy phones, Xbox controllers, and myriad other gadgets. Indeed, every year, humanity is wasting more than $60 billion worth of so-called critical metals—the ones we need not only for electronics, but also for the hardware of renewable energy, from electric vehicle (EV) batteries to wind turbines.
Millions of Americans, like me, spend their workdays on pursuits that lack any physical manifestation beyond the occasional hard-copy book or memo or report. It’s easy to forget that all these livelihoods rely on machines. And that those machines rely on metals torn from the Earth.
Consider your smartphone. Depending on the model, it can contain up to two-thirds of the elements in the periodic table, including dozens of metals. Some are familiar, like the gold and tin in its circuitry and the nickel in its microphone. Others less so: Tiny flecks of indium make the screen sensitive to the touch of a finger. Europium enhances the colors. Neodymium, dysprosium, and terbium are used to build the tiny mechanism that makes your phone vibrate.
Your phone’s battery contains cobalt, lithium, and nickel. Ditto the ones that power your rechargeable drill, Roomba, and electric toothbrush—not to mention our latest modes of transportation, ranging from plug-in scooters and e-bikes to EVs. A Tesla Model S has as much lithium as up to 10,000 smartphones.
The millions of electric cars and trucks hitting the planet’s roads every year don’t spew pollutants directly, but they’ve got a monstrous appetite for electricity, nearly two-thirds of which still comes from burning fossil fuels—about one-third from coal. Harvesting more of our energy from sunlight and wind, as crucial as that is, entails its own Faustian bargain. Capturing, transmitting, storing, and using that cleaner power requires vast numbers of new machines: wind turbines, solar panels, switching stations, power lines, and batteries large and small.
You see where this is going. Our clean energy future, this global drive to save humanity from the ever-worsening ravages of global warming, depends on critical metals. And we’ll be needing more.
In all of human history, we have extracted some 700 million tons of copper from the Earth. To meet our clean energy goals, we’ll have to mine as much again in 20-odd years. By 2050, the International Energy Agency estimates, global demand for cobalt for EVs alone will soar to five times what it was in 2022. Demand for nickel will be 10 times higher. Lithium, 15 times. “The prospect of a rapid increase in demand for critical minerals—well above anything seen previously in most cases—raises huge questions about the availability and reliability of supply,” the agency warns.
Metals are natural products, but the Earth does not relinquish them willingly. Mining conglomerates rip up forests and grasslands and deserts, blasting apart the underlying rock and soil and hauling out the remains. The ore is processed, smelted, and refined using gargantuan, energy-guzzling, pollution-spewing machines and oceans of chemicals. “Mining done wrong can leave centuries of harm,” says Aimee Boulanger, head of the Initiative for Responsible Mining Assurance, which works with companies to develop more sustainable extraction practices.
The harm is staggering. Metal mining is America’s leading toxic polluter. It has sullied the watersheds of almost half of the rivers in the American West. Chemical leaks and mining runoff foul air and water. The mines also generate mountains of hazardous waste, stored behind dams that have a terrifying tendency to fail. Torrents of poisonous sludge pouring through collapsed tailings dams have contaminated waterways in Brazil, Canada, and elsewhere and killed hundreds of people—in addition to the hundreds, possibly thousands, of miners who die in workplace accidents each year.
To get what they’re after, mining companies devour natural resources on an epic scale. They dig up some 250 tons of ore and waste rock to get just 1 ton of nickel. For copper, the ratio is double that. Just to obtain the metals inside your 4.5-ounce iPhone, 75 pounds of ore had to be pulled up, crushed, and smelted, releasing up to 100 pounds of carbon dioxide. Mining firms also suck up massive quantities of water and deploy fleets of drill rigs, trucks, diggers, and other heavy machinery that collectively belch out up to 7 percent of the world’s greenhouse gas emissions.
Metal recycling is a completely different proposition from recycling the paper and glass we toss into our home bins for pickup. It turns out that retrieving valuable raw materials sustainably from electronic products—toasters, iPhones, power cables—is a fiendishly complex endeavor, requiring many steps carried out in many places. Manufacturing those products required a multistep international supply chain. Recycling them requires a reverse supply chain almost as complicated.
Part of the problem is that our devices typically contain only a small amount of any given metal. In developing countries, though, there are lots of people willing to put in the time and effort required to recover that little bit of value—an estimated tens of thousands of e-waste scavengers in Nigeria alone. Some go door to door with pushcarts, offering to take or even buy unwanted electronics. Others, like Anwar, work the secondhand markets, buying bits of broken gear from small businesses or rescuing them from the trash. Many scavengers earn less than the international poverty wage of about $2.15 per day.

This is a BIG DEAL.
Cement production is one of the biggest sources of CO2 emissions that doesn't directly involve burning fossil fuels. Sure, making cement uses a lot of energy, but theoretically that energy could come from renewable sources that don't emit CO2. Even if it did though, the process of making cement basically involves baking limestone until CO2 and water are driven out of it, creating a substance called "clinker" that is ground down into cement powder. So, making new cement from limestone always emits a lot of CO2, no matter what energy source you use.
This research basically showed that you can use old crushed up concrete waste in place of the flux that is usually used in smelting/recycling steel. Flux creates a glassy slag on top of the molten steel that captures impurities and protects the metal from oxygen while its molten hot. Using concrete as flux basically re-bakes the concrete back into clinker, which can then be used to create more cement and new concrete, while not producing any new CO2 emissions because you're basically baking the CO2 that reacted with the cement to make concrete back out of it. Its like how burning wood doesn't increase the total amount of CO2 in the atmosphere, because the carbon in the tree originally came from the air. Its only digging fossilized carbon out of the ground and adding it into the air that's the problem.
This is a huge step towards decarbonizing our building materials, and it doesn't involve any fancy new technologies, or speculative processes. This could be done today in steel mills that currently exist, they'd just have to switch flux sources and start saving the slag.
What a brilliant piece of industrial research!

A Way You Can Store Your Vegetables For Months
Have you ever wondered how our ancestors preserved a whole winter season worth of frost-intolerant produce? Canning is a useful method, though a large harvest can easily turn it into a seemingly impossible task. The solution many generations before us turned to was building a root cellar.
Although many cannot build their own old-world root cellars due to rentals, adequate space, or urban environments; a little common sense and wisdom of temperature and humidity guidelines will allow anybody to whip together an ideal means of prolonging produce-life through the winter.
A conventional root cellar, which essentially is a room buried in a hillside or underground, meets only a handful of criteria.
INSULATION: The earth is a wonderful insulator. A typical old-world root cellar was literally buried on all sides except the entrance, utilizing the natural insulating properties of the soil.
VENTILATION: It is important that your make-shift root cellar can breathe. Warm stale air needs to float out of the top of your chamber as fresh cooler air makes its way through the bottom. This is important to keep humidity levels under control in order to prevent the rot of moisture-sensitive vegetables such as squashes.
DARKNESS: Light accelerates the decomposition of fruits and veggies. An ideal means of storage incorporates complete darkness.
Consider what you may have on hand if you would like to construct a practical yet permanent root cellar: Burying an insulated plastic or metal trash can with a tight lid is a popular option. Others have gone to the trouble of recycling an entire broken refrigerator by submerging it in a hillside. Another option is to frame off a corner of your basement with a window or vent. A more conservative approach is to sink a large cooler into the ground. If one of these avenues are chosen, make sure you are ventilating with a hose or pipe.
A blast valve or similar device may be incorporated to prevent below freezing temperatures from entering your storage compartment.
My personal favorite involves little more than a pile of straw, hay, leaves, or moss and a minimal amount of elbow grease. It is most effective with potatoes (Read on).
As a rule of thumb make sure not to wash any produce prior to storing. This will greatly reduce its ability to keep. Instead provide enough drying time for exterior dirt to dehydrate, then brush off any large clumps.
Apples can be a dangerous food to store with other produce. The idiom one rotten apple spoils the barrel is spot on. As apples age they release ethylene gas which causes other produce to rot too. It’s a wise practice to isolate them in shallow containers with lids. They keep best in 80-90% relative humidity and prefer temperatures of 32-40 degrees Fahrenheit. Check on them often and remove any signs of rot.
Beets prefer the same 32–40-degree temperature range but can withstand a bit more humidity. Outdoor storage is an easy and effective method to practice. Before hard frosts begin simply hoe dirt over the protruding shoulders keeping the foliage exposed. As winter begins, mulch over the rows with up to a foot (more for colder climates, less for warmer) of leaves, straw, or hay.
This method may be applied to carrots, parsnips, turnips, celery, rutabagas, cabbages, leeks, kale, and spinach with some success as well. Regarding flavor, the longer you can keep cold tolerant produce in the ground, the better. Cool fall temperatures sweeten many vegetables such as beets by literally increasing the presence of sugar.
Brussels sprouts are somewhat frost hardy and can be left in the garden until late fall. They may be kept in a root cellar for some time however a lack of moisture will shorten their lifespan. Like beets they prefer a temperature range of 32-40 degrees and high relative humidity of 90-95%.
Cabbage can withstand light frost when it is young and moderately severe frost when mature. Some varieties are briefly tolerant to temperatures as low as 20 degrees. The method of mulching beets above can be employed here. Cabbage prefers cold temperatures of 32 to 40 degrees and high moisture of about 80-95% relative humidity making it a good root cellar candidate. Either cut off the head or pull out the entire plant (roots included). If the roots are left on it may last a bit longer in a cellar, however if the stump is left in the ground a smaller leafy cabbage will emerge the following season.
Carrots can be kept in the garden under mulch just like beets. Remember to cover the shoulders with dirt. They prefer temperatures of 32-40 degrees and relative humidity of 90-95% in a root cellar. If storing in a cellar, harvest before the soil freezes, cut the stems close to the carrot, and store in a bucket of leaves or sawdust with a loose lid.
Cauliflower and Celery prefer cold temperatures of 32-40 degrees Fahrenheit and very moist relative humidity of 90-95%.
Celeriac is one of the best keeping vegetables during the winter months. Trim off the longer roots making sure not to cut too close to the meat. Store it in damp sawdust, sand, or moss at an ideal temperature range of 32-40 degrees and a very moist relative humidity of 90-95%.
Dry Beans can be harvested after pods are nearly dried out while still attached to the vine. Spread the pods on newspaper for a week or two until completely dry. A productive trick to separate the beans from the pods is to fill a bag and beat it with a stick. When a hole is cut in the bottom corner the beans will fall out pod-free. Dry beans store well in temperatures between 32-50 degrees though they can withstand freezing temperatures. They are less moisture tolerant at an ideal range of 60-70% relative humidity. Store in dry containers with tight lids.
Garlic needs to be air dried in a warm arid area for 2-3 weeks. Remove the roots and store at an ideal 32-50 degrees with 60-70% relative humidity and good airflow.
Leeks come in frost hardy varieties which should be utilized if growing for storage. They can withstand a bit of snow and the mulching process may be used up until the ground freezes. Harvest with some roots still attached and stored at an ideal 32-40 degrees upright, preferably in wet sand. Though leeks prefer a high relative humidity of 90-95% take care not to wet the leaves during storage.
Onions require curing until the necks are quite tight before storing. To cure, spread them in a dry area with sufficient airflow or hang them upside down. Ideal storage temperatures range from 32-50 degrees with a relative humidity of 60-70%. Make sure they are stored in an breathable container such as crates or mesh bags.
Parsnips store well in uncovered ground until a solid freeze at which point they should be mulched. The frost improves their flavor for a succulent spring harvest. Store harvested parsnips in damp sawdust at an ideal 32-40 degrees and a high relative humidity of 90-95%.
Potatoes should be cured in a dark place for 1-2 weeks at 45-60 degrees. After this they prefer cold temperatures of 32-40 degrees and moist relative humidity of 80-90%. A great means of outdoor storage is piling an insulating material such as straw or hay on top of unused winter garden space with a few inches of dirt on top. Make sure to keep a ventilation hole, clear of dirt, on one side of the pile and a drainage ditch around the perimeter equipped with a small runoff canal.
Throughout the winter hungry gardeners can reach through the ventilation hole and fish out the produce. If you have a tarp on hand covering the top of the pile, but not the ventilation hole, will prevent your storage mound from eroding away. If many potatoes need storing and more than one pile is not an option layer the pile with 4-6 inches of insulating medium, followed by a single layer of potatoes, followed by 4 inches of soil. Repeat the layering process.
Pumpkins should be cured like squash (see below) with the stem left attached and stored around 50-55 degrees. Relative humidity should fall between 60-75%.
Sweet Potatoes can be preserved all the way until spring if properly cured and stored. To cure, let air-dry in a warm humid environment of 80-85 degrees and 90% relative humidity for 10-14 days. This will toughen the skin and improve the flavor. Sweet Potatoes store best in an unheated room of about 50-60 degrees with a moderate relative humidity of 60-70% taking great care not to let them drop below 50 degrees.
Turnips should be harvested before heavy frosts, tops removed, and stored as you would carrots in a moist insulator such as sawdust, moss, or sand.
Winter Squash should be harvested before a hard frost when the skin is tough enough to prevent penetration from a moderately pressed thumb nail. Flavor is best when the seeds are given a chance to fully develop. Make sure to leave the stem on the fruit and cure for about 10 days at 75-85 degrees, ideally. Store them in a moderately dry and warm spot where the temperature doesn’t drop below 50 and preferably stays below 60 degrees. The best relative humidity for storage falls between 60-70%.

Hey Star, if it makes you feel any better, Sunny doesn't forgive Megs for what he did during the war either, but being mean when he's apologised and is trying to be better and make amends isn't the solution. Whether you choose to forgive him is up to you, but it's your fault if you choose to hurt him back. If you want to take out your feelings, do it in art instead. Sunny's painting a 'Wish you were here' postcard of the Urayan Wastes (the part with the boiling oil and molten metal pits, which Ratchet thought was mean, but it's his way of taking out his feelings harmlessly)
But I want to get even and he's a huge spike! And hurting him back is fun – I made him cry, this time. Hahaha! It was so, so satisfying. When he found out I had a spider in my room that he could've seen, I thought he was gonna spill all over the floor. I was a bit disappointed when he didn't. It would've been something else to laugh at him about.
I like the postcard idea! He should do a scrapheap one too. Or something. A recycling facility? Is he going to send it to Megabum when it's finished? Haha! He should. You know he should.

Chemists recycle shrimp waste as catalyst for hydrogen generation
Flexible spheres of the biomolecule chitosan, made from shrimp waste, can be used for catalysts that generate hydrogen gas from borohydride salts. In a paper in Green Chemistry, a research team at the University of Amsterdam (UvA) shows how the spheres can "breathe out" hydrogen bubbles without breaking. This is an important step towards practical and safe hydrogen storage and release units. Since 2020, the Heterogeneous Catalysis & Sustainable Chemistry group at the UvA's Van 't Hoff Institute for Molecular Sciences has been working on using alkali metal borohydride salts as future hydrogen carriers. These solid salts can be stored safely in air under ambient conditions and release hydrogen gas only when reacting with water. However, controlling the hydrogen release, and thus preventing runaway reactions, is challenging. One solution is to stabilize the solution with a base, and control the hydrogen release by using a catalyst. The UvA team, led by Prof. Gadi Rothenberg, is developing such catalysts in collaboration with the Austrian Competence Centre for Tribology (AC2T) and the company Electriq Global.
