any thoughts from the group regarding this company, their approach and their recent press coverage? Somewhere between Helion and Rossi?

re Helion, yes that direct energy conversion design is the winning ticket imo I recall in their early and spacecraft propulsion designs a single FRC was accelerated, compressed, expanded and exited if I understand now, the acceleration and compression are followed by expansion/collision and the merg...

well considering we could have been running the whole show on MSRs since the 70's and mitigated the carbon climate debacle, imo the 'total failure' has already happened.. now we are out of time and building these huge energy harvesting systems that will be obsolete in 20 years when nuclear finally g...

yes 80% seems pretty astonishing number

can't wait for the next-gen fission/fusion fleet build out, can't be soon enough..

this group has impressive scaling strategy
https://thorconpower.com/

yes the capacity scaling is limited by the tanks
also what PSI can be obtained through pumping into a sealed tank, this setup would seem to be limited in energy density

but an interesting workaround of the long-standing isothermal problem in gaseous compression through gradual bulk compression

also for your consideration

now they claim >%80 efficiency

Hydrostor claims efficiency of >=60%

Why do you think the 'Helion' type device cannot perform p -> Boron fusion?

That is an interesting paper, looks like Tri-Alpha has built a duplicate of the Helion device, pretty far removed from their published patents..

In that NBF link they discus direct energy recovery through back emf in coil windings, something made theoretically possible by the pulsed operation.

They had an older design where a single FRC was compressed and then expanded and cooled in a very elegant direct energy conversion scheme, I guess they needed to go to the 2 opposing FRCs and had to abandon that design. Interesting that they are not including extra compression technology a la Genera...

Re Helion and similar approaches using the FRC it would appear that these designs have the great advantages of an inexpensive geometry and of being able to transport the plasma through the device as opposed to a stationary plasma. So the input/combustion/exhaust apparatuses can be separate as in any...
