Can you tell me what the very good reason is why Helion has to manufacture capacitors in-house? My understanding is that Helion's cap design is actually an older one that isn't readily available anymore, due to the specific performance characteristics they need for their energy capture design. I co...

45x Tax credit expanded for fusion energy The Fusion Advanced Manufacturing Parity Act was introduced in the House and Senate, expanding the Inflation Reduction Act’s 45X production credit to include fusion energy components. The bill creates a 25% credit for fusion technologies, ensuring that the ...

Of the usual suspects -Sonny White launched "Casimir Effect Energy" startup

You have to admire his tenacity, if nothing else.

No more bird mulching windmills & their grifters for one.

No more farm-land devouring solar farms and THEIR grifters either.

Well, as hope fades for the IVO Quantum Drive, yet another company appears on the horizon: https://qde-inc.com/ I don't have the mental energy to try to understand how they claim it works, but in a recent tweet, they mentioned a 2026 orbital test. I've read this through twice now. If I understand c...

Getting myself up to speed on this one, is the tangential NBI part of the technology, or just an artist's rendition of some other phenomenon?

This is really exciting, particularly in Texas, because of all the abandoned oil and gas wells in the state. These could easily be reopened and bored further to tap geothermal. The picture of the bore cross-section is really nice, because it makes this a technology that ACTUAL WORKS, and works as ad...

So, bang two spinning (counter-rotating? not clear from the paper) rings of plasma together at (presumably) high frequency to get fusion? Is that the gist of it?

If Trudeau up there had diverted even a tithe of all the money he was wastefully throwing around on woke causes (or just plain losing track of), General Fusion could have been funded to the hilt. A lot better of an investment in the future of the world, in my opinion, especially given how they are ...

Maybe this is a better venue because there can be so much noise on Reddit.

My experience on Reddit has been that the name of the subreddit generates only opposing discussion. r/fusion? Only people that say it will never happen, or a bunch of ITER die-hards.

Polywell will always have a special place in my personal research journey. Agreed. I, and I'm sure others as well, had visions of Polywells powering ships with Mach-effect thrusters traversing the solar system. We may not get the later, but certainly the former is still alive and kicking, and for t...

Absolutely insane engineering there! I did not believe they would be able to do it at the very first attempt but they did! Science Fiction is boring in comparison! Watching the video shot from the top of the tower with the arms ever so gently squeezing the booster, the controls team needs a raise a...

B field strength also seems low compared to other projects. Is this due to the size?

I hope that it solved your doubts. It did clear up some things, so thank you. What wasn't mentioned in the paper, or maybe it was and I glossed over it, was whether or not the goal is a pulsed-mode or continuous operation. 300 kV is a lot of voltage to try and maintain over long spans time. We're t...

Just finished reading the paper. Maybe this is a silly question, but how do you keep the ions from crashing into the cathode at the required KEs needed for fusion? Is that the breakthrough here, that the feedthroughs are such that the cathode voltage can be dialed high enough to prevent this?
