They're emphasising their efficiency, which as a physicist agree is important, but I can't help thinking that it's much more important to eliminate the cost and delay of obtaining and installing all those heat exchangers, turbines, and generators. Speaking of supply chains, has anyone at Helion spe...

Stock market conspiracies is taking it to far. Please don't foul the thread with that sort of thing. We see large construction work, visits from high ranking officials, interviews with young enthusiastic technicians among large scale pieces of equipment in huge warehouses, filed patents, peer review...

yes, Helion looks strange because they aren't building a fusion reactor, like everyone else is doing they're building a fusion reactor factory their goal is to pump out 50MWe units like aircraft that seems absurdly optimistic because almost no one has been able to a plasma ignited for more than a f...

The talking of supply chain issues gives me bad feelings. Helion haven't yet got a decisively proven technology. Once they have that, they'll have access to pretty much any resource needed to get it into serial production. Fishy priorities really... Yes, theres has been de-industrialization but the ...

The Helion company has recently aquired a patent with the title: "Apparatus and methods for generating a pulsating high-strength magnetic field"

I found this also: https://www.dailycardinal.com/article/2025/10/how-three-madison-researchers-broke-ground-in-the-fusion-world The simulation showed that by introducing tactics to control the instability, WHAM could confine plasma for around 100 microseconds. Though this number is still lower than ...

Another disappointment! Seemingly bad news: https://www.ornl.gov/news/ornl-leads-three-infuse-projects-solving-fusion-challenges WHAM generated its first plasma in July 2024, but exhibited relatively short confinement times. To address this issue and better predict device performance, Realta is deve...

What else can they do? There is no He3 to buy so they have to make it themselves from the D-D reaction. This is not quite correct. There is He3 to buy. It costs 20,000 USD/gram. Not economic for power plants, but does not matter for tests. May it be as it will with that. They will still have to run...

Oh dear... Northvolt was a massive failure. Some even say it was a scam. Whatever it was, the money is gone and the Lyten Company got themselves a huge amount of hardware and real estate. At a bargain price. The press here in Sweden has called the spectacle "the ant that bought a dead elephant". So...

The Lyten company has acquired the former Northvolt establishment in Skellefteå, Sweden: https://www.di.se/nyheter/northvolt-saljs-till-amerikanska-lyten/ The American battery manufacturer Lyten is buying Northvolt. The assets are valued at 50 billion kronor – but Lyten has not paid that much. “The ...

Hmm. So I guess the strategy is to use D-D to tune the device for the right plasma conditions (e.g. triple product), then D-He3 and further tuning to maximize the fusion, then yet more tuning to maximize the direct energy out. Hopefully that will demonstrate net electricity production. It seems to ...

Someone has obviously found it worthwhile to spend the money needed for a patent application for this contraption:
