#solar pumps for dams

[iatrophilosophos]

Like. Fucking. Hell. Electricity can be a legitimately useful resource but we For Real do not need this much of it

There are so many ways of producing electricity that are dependent on like either damage that has already been done (hey fun fact didja know solar fields decommission panels after a certain number of years? they hit like 80-90% of their original efficency and get rotated out even tho they're still very much capable of working fine!) or are just actually pretty reasonable at SMALL scales (hydro with a little water wheel from a small pond on a big creek -> can even increase biodiversity so long as ur like, paying attention and not fucking migrations with how you build things, diverting small amounts of flow from an already downhill stream for a few dozen yards can be basically fine, there's also gravity pumps uphill catchment tiny water towers etc; these systems just work with magnets and rotation, it's municipal generation and larger scale dams that get Bad)

None Of These will power millions of peoples home microwaves and electric kettles and cars and lighting and industry and all that bullshit. But there's many many years worth of reclaiming all the toxic extracted shit to power like, medical equipment. Eventually these things will fall off too, break for the last time and not be able to be fixed generations from now, but that's a lot fucking better bet for ur gr8 gr8 grandkids than no complex life on earth!

Do not fall for the trap of collapsing imperial core luxury into needs. It's unhelpful and makes you look like a callous, whiny fool. Differentiate what you need from what youve become accustomed to demanding. The world is fucking chockablock with materials that shouldn't have been made in the first place but fucking exist now, we cant compost trillions of miles of copper power lines. Municipal scales kill. Your toaster oven is not a ventilator.

For farmers, there’s now another option: connect one of your dams to a river – or link two dams together – to create a small pumped hydro plant to store electricity from solar to use at night. The water in your dams could offer yet another form of self-reliance.

Our new research has identified over 30,000 rural sites where micro pumped hydro could work. A typical site could produce two kilowatts of power and store 30 kilowatt hours of energy – enough to run a typical home in South Australia for 40 hours.

An Acquired Taste

It was an uncommonly hot autumn day when Yulia Lebedeva first tasted fruit.

By the standards of New Seoul, the phrase ‘uncommonly hot’ seemed naive. From the great hydro-powered pumps and dams working around the clock to keep the Yellow Sea at bay, to the multicoloured throng of fans whirring from roadside bazaars, the city of twenty-six million was shaped, moulded, created by heat. It may not have been Hell, but there was no denying both places had a connection to the same feverish warmth.

The teeming thoroughfare of Sambong-ro yawned before her. Rickshaws shot past lumbering solar landbarges, the cacophony of pedalling legs and hydraulic whines drowned out by the background hum of sheer humanity. The pavements and main roads were supposed to be a pristine, reflective white: years of wear underfoot had turned them into a dirty ochre. It reminded Yulia of videos she’d seen about the Amazonian savannah, and the humans crawling across it of the late wildebeest; flowing like sand through fingers. Despite each individual destination, the masses kept an unconscious, graceful totality quite unlike anything she’d ever seen.

Nevertheless, it was a little overwhelming. Shuffling left past a haggling seaweed-seller and kicking aside a discarded plastic bag, Yulia eased her way into a claustrophobic canyon. Her first thought was that the sun had been inexplicably cut off; the staggering heights of the surrounding buildings had plunged this narrow alleyway into a strange twilight. Whereas before she had been sweating in the stagnant humidity, now an artificially funnelled breeze was at her back. 

The light was bluer here, relying more on artificial lighting than the meagre strip of sky daubed overhead. Faded, mottled walls, a pervading sickly stench and a collection of ramshackle vendor’s huts conveyed the area’s poverty. A window-mounted softscreen overhead flickered and buzzed, sending a trail of boron-green sparks skittering down like ash from a cigarette’s tip. Music quietened as she walked further; the clang of metal gantries echoed above as inquisitive inhabitants rushed out, peering closely at the presumably lost foreigner.

The stench grew stronger as she reached the vendors and their wares; the faint, leafy scent of algae vats, the spicy, cloyingly sweet tang of soy-beef and the metallic stink of blood and assorted bodily fluids. An old lady, perched behind what looked to be a fruit stall, yelled a few words in what sounded like Mandarin. Yulia smiled back in what she hoped was an encouraging way and pointed to the translator device looped around her left ear. A moment later, the fruit seller’s words were whispered in perfect, monotone English, directly into her ear.

“Hey! Lost lady! Want to try some fruit? Real fruit, from Hokkaido, not vat-grown, no soy-fruit! 60 Sphere-yuan each!”

Real fruit? From a real tree? I’ll believe it when I see it, thought Yulia. The few remaining fruit plantations were guarded and tended to by corporations or the ultra-rich; not piled in front of a stall in some backwater New Seoul alley. She peered closer; the fruits were pear-shaped and a deep ruby red, with small green seeds rippling their skin. It was probably just another vat-grown scammer, she rationalised to herself.

Yet, her curiosity was piqued.

“Can I…” Yulia said slowly in English, pointing to herself, “...try one first?” she asked, pointing to the fruit and miming a bite. The woman nodded, and held out her right index finger to transfer the funds. Yulia’s fingerpad pressed against the old woman’s for a moment, then down, grabbing a fruit from the topmost row. A sharp word was uttered by the seller as Yulia brought the fruit to her lips.

“Enjoy!” said the translator as she bit down.

Her first thought was confusion. The flesh of the fruit was moist but not juicy, and had a surprising amount of thickness to it. It was almost…chewy? Crisp sweetness rolled around her mouth, a sugary taste so unlike the food tubes she was used to back home at the Institute. The seeds stuck to her teeth and cracked: they filled her mouth with a tart, sour tang. It seemed similar to the flavour pouches she’d once eaten marked ‘passionfruit’ yet a world away in execution. Delicious had never before seemed so ordinary a word.

“What…” Yulia asked, pointing at the fruit in an almost reverent way, “is this called?” 

The fruit seller smiled, straightening her apron as she talked. The grin splitting her face made it seem as if she was chatting to an old friend.

The translation device filled in the gaps: her son was a genesplicer in Hokkaido North, and had sent his mother a bag of his corporation’s newest crop. Bad reviews had sunk the fruit’s commercial rating while thousands were still to be harvested; therefore, her son could send these discarded fruits to New Seoul for a very low price.

Yulia nodded. “How much for the rest?” she said, pointing at several fruits and then at her index finger.

“If you want a dozen, I'll charge 550 Sphere-yuan. Save you some money.”

Yulia shook her head and swept her arm in a wide arc, over all of the fruit. The old woman’s eyes widened and she ducked below the booth, muttering too faintly for the translator to hear. A moment later, she resurfaced with a fabric bag clutched tightly in her gnarled right hand.

“3,000 Sphere-yuan for the lot. You sure? I’ll tell my son: his fruit may not be successful in Hokkaido, but it certainly is here!”

Yulia nodded. Taking the proffered bag and briefly touching fingers again, she placed each fruit into the plastic bag, taking meticulous care not to bruise it. If she could return to the Institute with some of this… reverse-engineer it in the genetics lab… why, the fruits would be worth their weight in gold. No flavour pouch, no algae, no soy-meat would ever come close to the taste she had just experienced.

Smiling, she bowed to bid the fruit seller farewell, and continued further into the artificial canyon she found herself in. As the stall receded, the translator picked up one last, garbled whisper from the old woman’s direction.

“Tourist,” it said. Yulia thought she could feel the contempt, hidden somewhere in its impersonal tone.

HARNESSING THE WIND

It took me a long time to realize that FEAR has such paralyzing effects. It prevents me from doing or saying what is right and proper. Fear has absolutely no value at all except, perhaps, the instinctual fear of danger.

Therefore, I must get rid of fear, I must overcome it, as soon as it surfaces. Why? It is because fear is like a bottle cap. It must be removed so I can taste the goodness and sweetness inside me - my own self-worth, drowned constantly and easily because I had been afraid.

I shall tell you my true story.

This happened many years ago. I was searching, not searching to find, just searching and .... waiting.

To make a long story short .... I eventually ended up at the Niagara Falls. I just stood there all by myself at a strategic spot.

At the opportune time, when I felt I was ready to take the plunge, I took a deep breath and looked up to the sky. Then, on breathing out, I let out a deafening scream, looking down to the rolling thunderous rapids. Strangely, this had the phenomenal effect of throwing out the potent cocktail of emotions all bottled up inside me, to be carried away by the raging monstrous water below. It was an internal cleansing, much like getting rid of the waste and rubbish, accumulated and piling up, in my study.

I felt so relieved I just cried, allowing the hoarded tears to burst the dam within me. I felt the tears come, flowing freely down my cheeks - hot tears, like dripping wax.

Oddly but pleasantly - with sprays from the waterfall on my face, my entire body and drenching my clothes - I felt I had just been sanitized from impurities that had contaminated me from within. With cleansing came clarity. And I could see clearly. For the first time in my life, I understood what it meant to be truly free and to be totally unafraid of the tormenting forces that used to affect and control my life.

With understanding, came a mental shift of a 180-degree turn to face and to embrace the hidden part of me - a part I had never knew existed. As I took in my next conscious breath, everything around and within me changed. It seemed that the external rapids was entering me, flowing like a gushing stream, cutting through walls of stones and rocks inside me - the noise too transforming into silent whispers, to let the peaceful river flow.

It was a feeling of being conquered, captured to serve my new king, abandoning the old. I felt certain a revolution was taking place in my inner self. A new government was taking over my misguided territory, to implement the laws of nature, replacing the laws of men.

Suddenly, images appeared on the screen of my mind. I saw them clearly - images of windmills and waterfalls, spinning turbines, water pumps, solar energy reflector plates, movers, generators, hydroelectric stations and irrigation canals.

Inside me, there were vibrations and turbulence, earthquakes and stormy seas, strong winds, flashes of lightning and sound of thunder, revealing to me there was a much bigger storm inside me that could be similarly harnessed to be of true service for many good and functional purposes and for the benefit of others. Thus, I termed this transformation, Harnessing The Wind.

It was a transformation that gave me my first glimpse of the spiritual realm, implanted in my soul as an assurance of lasting hope: a hope to persevere with courage and confidence should I ever again encounter the storm of adversity, suffer the devastating effects of temptations, or face the dark clouds of despair, misery, boredom and fear.

I searched,

And I was found.

Photograph taken the morning of August 23rd, 2325 AD, of Remo Dam. In Skeena Valley Tribe territory, former territory of British Columbia, Canada.

Remo Dam serves an important purpose as a source of hydroelectric power and fresh water for the city of Terrace. During the day in the summer, water is pumped from the Skeena River into the Remo Reservoir when solar energy is abundant. During the night, the dam lets out water to power the city. The Remo dam is also used as an important location for aquaculture. It serves as a large source of genetically engineered algae used to make diesel fuel to power vehicles and heat homes. During the salmon spawning season, a fish ladder is employed to carry salmon up into the reservoir to spawn. While half the salmon are caught as a source of food for the city and an important trade good. Terrace has become more important after the world saw sea levels rise 8 meters with climate change, flooding Prince Rupert. As such, the city is a major hub of trade between the Pacfic Ocean and the Haida Gwaii and the inland areas, particularly Amiskwaciy.

some words of hope from here in california:

the solar dump isn't 100% bad, as for the first time in forever we've been keeping up with the power demands of the heatwave (the sun powering the AC is lightly poetic; 1/3 of our state is actual desert and usually our power grid struggles to keep us cool during the worst of the summer, but not much this year, the hotter it is, the more power going to the grid, so at least one part of the system is working well)

More importantly, we have a bunch of new solar batteries! Giant batteries explicitly for storing solar power overages. Batteries that can store such huge amounts of electricity are new tech, grid-capacity battery storage is still something humanity is in the middle of developing (and california and texas are trying to lead the charge on that development here in the states) and now we have some working versions (one of which is basically just using the electricity to pump a bunch of water up into a hydroelectric dam, so we can release that water to create electricity later, if that gives you any idea what stage of tech development we're at in the problem of grid-capacity electrical storage)

We're not at zero problems, of course, and like all californians i continue to loathe our power company PG&E, but we are making progress!
