Re: More Helion Energy news....

@Helion_Energy May 11 There are some interesting things happening again on the fusion space propulsion front. Hopefully more information to be released soon. Helion team knows fusion, and this tweet is not an idle comment. Anyone have any idea what Helion might be working on in space propulsion? Ch...

Re: More Helion Energy news....

The point is that TAE's plasma is created once, and once created it is maintained as long as they keep the neutral beams on, hence, no divertor issues. Plasma losses are controlled by controlling plasma stability and the key finding demonstrated with Norman is that the higher the temperature the bet...

Re: More Helion Energy news....

TAE's confinement time is until the neutral beam is shut off and that is a limitation of their experimental machine (takes a lot of power to run those Megawatt injectors). Confinement time is not a limitation of their process. In a TAE commercial machine the neutral beams will not shut off. Helion r...

Re: More Helion Energy news....

"I think most other teams are not even close to worrying about things like divertor erosion/material deposition." Unlike Helion which continuously pulses plasmoids through the divertors every cycle to collide, TAE divertors are not in continuous use because their plasmoids after colliding form a sus...

Re: 2021 state of the horse race: ITER vs. dark horses

Is it just my imagination or are these main contenders ramping up their PR? Getting close enough to commercial to start beating their chests?

Re: NASA: Lost its grip on reality or accepted it?

Yes, budget constraints forced NASA into the briar patch. The joke is that SpaceX would have just gone straight to Mars if they did not get money for the Moon. And if money was the deciding factor, SpaceX would be the human transport to Lunar orbit rather than Orion.

Re: NASA: Lost its grip on reality or accepted it?

NASA looks to have made a decision based on SpaceX demonstrated ability to launch real rockets at a far lower cost than their competitors. Further Starship has flown, it is landing that they are still working on. The booster for the Starship is using the same engine and construction methods. Finally...

Re: General Fusion in the news

One 'small' detail I missed in their new design is that the internal pistons and liner that is in contact with the molten lithium rotates in synchronism with the molten metal. The driving pistons and thicker outer vessel then is stationary and is coupled with the inner pistons with some kind of work...

Re: General Fusion in the news

Originally they were going to use lead for the molten metal, but the issue was the surface of the compression shock wave had small droplets that would eject from the metal surface into the plasma which would quench the reaction. To deal with that their thought was to use a thin layer of lithium so t...

Re: 2021 state of the horse race: ITER vs. dark horses

The problem with peakers is thermal cycling. The problem with solar is low power density, the need for storage, no support for heavy industry which is a 24hr operation. Wind has fatal weather issues, Germany, England, Texas can attest to that. There were cost numbers for GF a long time ago and given...

Thank you for that link. TAE has been on schedule so this gives a good idea for utilities and regulatory bodies.

Re: 2021 state of the horse race: ITER vs. dark horses

Getting the plasma right so that it could be compressed adiabatically and remain stable during compression for GF was tough, but in the end their final plasmoid remained stable long enough that their piston compression could be slower than they thought they needed in the beginning. It turns out a sl...

Re: 2021 state of the horse race: ITER vs. dark horses

"They changed from a compact toroid to a tokamak." GF has tested several plasmoid shapes in search for one that could be adiabatically compressed and remain stable. It is called a test program. They now have a design and built a nearly full scale injector that meets their operation needs and which h...
