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...

Re: Small Tri Alpha news blurp

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...

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

As to GF's plasma, they built their plasma injector and tested thoroughly compression of the plasmoid created by it. This is old ground.

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

GF has not significantly changed their design, it only looks that way superficially. GF achieves their spherical compression via piston timing. It boils down to cost and lead time to build. Modeling is what is enabling them to use an easy to manufacture, lower cost cylindrical compression vessel. As...

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

I would suggest that GF is looking ahead, is already sharpening their pencil. This is now about being the most attractive alternative.

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

TAE, based on their published research has two focuses, one on developing and proving their plasma measurements, their so called diagnostic suite, the second is to advance and prove their plasma modeling, including neutral beam and electron heating modeling. These two are strategically tied together...

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

" I am not sure what "announced a demonstration power plant" means in your book. Is it full scale? " You are not understanding the difference between science and engineering. When a company makes a demonstration plant they are gathering engineering data. TAE and GF are investing in devices to get th...

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

I am sure that deep pocket investors in TAE and GF are convinced that their projects are as near a sure thing as can be had. It no longer takes full scale hardware with neutrons as computers and simulations have advanced significantly and convincingly so to investors. Why else has the money leaked o...

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

As far as I know there are only 2 companies that have publicly announced fully funded demonstration plants and are actually staffing up to design and build them. They are GF and TAE. Further, what is important in real terms is not the claim of 'first', but who can actually sell and build commercial ...

Re: Small Tri Alpha news blurp

Gathering data for proving their models, proving controls, not for 'specs'.

There have been comments about avoiding He3 because of permit delays to a project that its use would cause.

Anyone heard timeline for Helion and LM (or heard anything about LM)?
