The magnets that TE is using are much smaller, because they use HTSCs. Those can hold a much higher current than low temperature super conductors. It seems that they are also more quench resistant.

Nevertheless is for sure worth keeping an eye also on these guys. Oh absolutely. IMHO TE and Dennis Whyte of the MIT (who spun off into CFS) have a chance to put tokamaks back on the map as a viable design. The giants of ITER, DEMO and co lost me years ago. Both have a good team. CFS just started b...

Here's a three-minute video presentation by their CEO, Jonathan Carling: https://www.youtube.com/watch?v=pfPZqZyZeyw He says they've completed another round of funding and are very well funded going into the "end of 2019", so it's a little dated. That is not what I hear. I hear that they ...

ZAP has updated their website: https://www.zapenergyinc.com/ Plans to achieve Q~1 by 2022! That is aggressive though not surprising for me, given their track record to date and quite frankly, I would not be surprised if they got there sooner. In any case, the race is getting hot and ZAP is among the...

I believe they still need another 100 million to actually build the demo reactor.

Latest results from Norman: 30 ms steady state plasma, 400 eV electron temperature. From what I understand they have a density of 5x10^12 to 5x10^14 cm^-3. That is OKish, but not Earth shattering. I was honestly expecting a bit more, especially temperature wise, but maybe they will push it further. ...

At the amounts of fuel that we are talking about here, tankage mass is of secondary concern, I think. For a mass mission at 0.1g (near) constant acceleration/deceleration, I calculated 70 tonnes, though actually it would be less since you lose fuel mass over time. So probably more like 50 tonnes. Ta...

Wake me up when they are producing neutrons...

They have a section on their website devoted to it. Seems like they got a 3.5 million ARPA-E contract:

Looks like Richard Nebel is working on a new fusion reactor design. Looks interesting. I wish him the best of luck!

This is pretty cool! Go ARPA-E! My only question is: Why are concepts that have achieved 10^10 keV *s/m3 not eligible for concept funding? That seems a bit counter productive, doesn't it?

Pardon the platitude but I think we need t dance with the girl we brought to the dance. He3 is not available or a ready source available. IMHO we should strive for PB11 or D-D Well, if you can do D+D, then you can make He3 as a fusion product. That is what Helion is doing with their reactor. First ...

Third-generation fusion fuels 3He + 3He → 4He+ 2 11 p 12.86 MeV 0 https://en.wikipedia.org/wiki/Helium-3 What about this reaction mixture? I remember hearing about it but it isn't talked about much. You could get the He3 from the decay of Tritium bred from Lithium as has been discussed, or from the...

Just noticed that GG made a mistake in his calculations. He assumed a neutron yield per second. I am pretty sure that they are talking about a neutron yield per shot. One of their shots lasts a few nanoseconds...
