"Like atoms coming together to release their power, fusion researchers worldwide are joining forces to solve the world's energy crisis. Harnessing the power of fusing plasma as a reliable energy source for the power grid is no easy task, requiring global contributions."
"Triangularity refers to the shape of the plasma relative to the tokamak. The cross section of the plasma in a tokamak is typically shaped like the capital letter D. When the straight part of the D faces the center of the tokamak, it is said to have positive triangularity. When the curved part of the plasma faces the center, the plasma has negative triangularity."
""It's a potential game changer with attractive fusion performance and power handling for future compact fusion reactors," he said. "Negative triangularity has a lower level of fluctuations inside the plasma, but it also has a larger divertor area to distribute the heat exhaust."
The spherical shape of SMART should make it better at confining the plasma than it would be if it were doughnut shaped. The shape matters significantly in terms of plasma confinement. That is why NSTX-U, PPPL's main fusion experiment, isn't squat like some other tokamaks: the rounder shape makes it easier to confine the plasma. SMART will be the first spherical tokamak to fully explore the potential of a particular plasma shape known as negative triangularity."

Another comparison of the two most promising varieties of fusion reactor, tokamaks and stellarators. I used to work on tokamaks and now I'm doing stellarators and let me tell you. It's been an adjustment.

Scientists have overcome two key barriers to producing power from nuclear fusion, which could pave the way for producing near-limitless clean energy. The scientists have ensured that the nuclear fusion reaction overcomes the two barriers to operating in a “sweet spot” for optimal power production: boosting the plasma density and containing the dense plasma. A tokamak reactor is essentially used around the world for producing energy from fusion reactions. The reactors have a donut-shaped interior which is covered with magnets.

RSEC 3rd Gen "Janissary" AIU
The Janissary is the primary combat unit of the Republic of Stauros ExoCorps, the military force associated with Stauros's Department of the Exterior.
Pilots are selected through the prestigious Janissary program, wherein adolescents who fit the necessary criteria are chosen to become career soldiers. The crux of the program relies on teaching pilots to effectively utilize ext-SYN/TRA, a crude yet minimally invasive application of Stauros's synaptic transfer protocol. While more advanced applications of SYN/TRA are afforded to elites within the program, because of the inherent risks involved in its use and the fact that only an estimated 3% of humans have sufficient bio-compatibility, it does not see widespread use.
As the military arm of the Department of the Exterior, the ExoCorps's primary aim is to secure national interests regarding extraplanetary resources, transport, and exploration, which extends to maintaining Stauros's monopoly on space travel. Because of this, Janissaries are designed to be capable of combat both in and out of atmosphere.
Their propulsion is fueled by a single Tokamak reactor, which heats air for a jet engine within atmosphere and vents plasma outside of atmosphere. Because of this, leaving atmosphere unaided significantly reduces the life of the combat units, reinforcing their role as being primarily planetary forces.

Phase II Engineering
Lets talk about the Phase II Engineering Set
Tumblr media
Here the set is under construction
Tumblr media
Initially the shaft was a smooth tube, but this would gain additional detail as seen here (photo from contemporary fanzine)
Tumblr media
This post by ArtofTrek shows that the concept behind the chambers - much like a Tokamak reactor ( https://twitter.com/ArtofTrek/status/1733598547335946593 )
Tumblr media
From this Phase II Enterprise blueprint (cleaned up by David Shaw) we can see that Engineering is immediately below the pylons. Instead of splitting the plasma of as with the TMP warp core onwards, the Phase II core would have set it straight up.
Tumblr media
Test footage was shot on the Phase II Engineering set. This was to see how much of the set could be salvaged, how well it stood up to widescreen movie filming. The Phase II costumes were used for these tests.
Tumblr media Tumblr media Tumblr media Tumblr media
Engineering as seen from the upper level - now with health and safety rails
Tumblr media
Once TMP went into production, the Phase II set was converted into the motion picture set. One wall was opened up to extend the core. The red ceiling supports were retained, but boxed in at the sides to hide the hexagonal lattice. Image from ArtofTrek
Tumblr media
The Phase II ceiling textured material was removed and repurposed for location filming of Vulcan at Mammoth Hot Springs in Yellowstone National Park. The textured material helped to protect the hot springs surface during filming
Tumblr media
This set would be remodelled to become the TNG Engineering set and retained many of the features. It would also be used in ST:VI
Tumblr media
It would be remodelled again for Voyager Engineering The columns, side wall, ceiling supports and upper level still existed in this set.
Tumblr media Tumblr media Tumblr media
After Voyager, new ships had new built from scratch Engineering sets. Phase II Engineering carried on through a refit, a new generation and a voyage to the delta quadrant.

Iizunamaru Megumu stares at the phone on her desk. Her geta clack against the floor awkwardly. Dare she? Dare she not? The number is right there. She can press "Call" at any time. She frowns. She can hear a pair of her underlings- two crows, probably- having an argument at the group printer. A kind of argument everyone knows the contours of. There's a light thud as one shoves the other against the wall, cawing as they break away from making out to snap at each other-
Her finger jabs the phone. Tenkyuu picks up on the third ring. "Hey," Megumu begins. And then pauses. "I know," she says, "that things didn't work out for us. We needed some space, some breathing room"- another thud from outside- "but we agreed nothing had to be final." A click. Tenkyuu has hung up.
She lowers the phone and stares with an expression indescribable in human language, emotions fusing together like they've been put into a tokamak reactor with the magnetic fields fired up.
She scrolls down to Himemushi. Presses "Call". Himemushi picks up. "Listen. I know we didn't-" her voice catches. "I know it didn't work out, I know, OK? But maybe we can keep it casual, light and free and-"
Momoyo interrupts. "I didn't believe it."
"What?" Megumu's face is a portrait of pure confusion.
"I didn't believe that you'd lost your girltwink to the Moriya's shrine maiden." She chuckles. Megumu can feel the knuckle-cracking that surely must be accompanying it, the stretching. "And then you come running to me, now that you've lost that tight ass and that thin-lipped mouth and that sycophantic river pouring from her lips."
"This has nothing to do with Kudamaki," Megumu says. "It's about us. You and me. What we could have together."
A pause. Momoyo's voice is awkwardly gentle when she speaks again. "Iizunamaru... you're not a bad fuck, OK? The problem's never been with what you can do to someone, what someone can do to you. Physically." She takes a deep breath. "But lately I've been getting kinda tired of trying to eat women out at arm's-length, ya know? Not just you, not only you, but... I'm not gonna go for a casual lay unless she's gonna cuddle afterwards without thinking about it."
Megumu's hand trembles. "Iizunamaru... Megumu. Are you OK? I'm not telling you, 'absolutely not', all right? It ain't a good time, that's all, and I'm sorry you're frustrated, even if it's kinda funny to think about your little tube fox getting collared by the Kochiya girl..." Momoyo's compassionate, or as close to it as she can sound. There's something grotesque about that to Megumu.
"I'm completely fine. Have a very nice day, Himemushi." Click. Phone down on the desk.
"Shit." She mutters to herself. "Shit, shit, fuck, fuck, what now, what now." Possibilities loom. Terrible, but among them- she pulls the phone back up and scrolls around some more. Finds the number. Calls.
"Komakusa? Yeah, hi, Iizunamaru Megumu, I helped you dodge any problems with your business operations a little while back, very grateful to you for keeping my girls happy- listen. I have a favor to ask. Do you arrange tricks?" There are no tears. There is a light smile on her face. Her geta are beating into the floor like Raijin guides them.

As a machine myself, I'd like to know the most environmentally safe energy source. Batteries? Solar panel stuff?? I just need a diet man tryin not to kill the human peoples or whatever
green hydrogen if you can manage it! batteries are extremely unfriendly to the environment. Solar is alright, as well as wind. I have a tiny tokamak reactor I keep as a pet. He was a rescue
