Re: Tokamak Energy news

And the move is complete (or almost). That was quick:

Re: SpaceX News

Booooring launch today! Barely could see anything because it was dark and fogy.
Successful first stage landing, despite strong winds.
The fairing recovery did not work out because of the strong winds. The parachutes drifted too far off course, I guess. Hope they will have more success next time.

Re: Small Tri Alpha news blurp

It is not quite that simple. ITER is not just about building the plant in France. The ITER project has employed dozens of research labs all around the world and that research has contributed a lot to our understanding of plasma physics. The simulation software alone has helped a lot of private fusio...

Re: Small Tri Alpha news blurp

2019! SJ, I hope you are right. ITER will dry up immediately and funding will flow to the others (IMO). There may still be hope for Polywell. So many things will take place with such success announcement. I don't think that ITER will dry up. Rather, I think that more private investors will jump on ...

Re: Small Tri Alpha news blurp

Norman is supposed to show that they can reach temperature, the next scaled up revision to determine engineering specs, then they build a demo. A demo late 2020's is huge. There is enough fossil to not fret. The next reactor, Copernicus will reach break even or higher. Demo will include energy conv...

Re: Small Tri Alpha news blurp

I think that was for break even. And yes, it seems like their timeline moved to the right a few years.

Re: High-temperature superconducting tape for magnets at 50+ tesla

That ties in with what I recall of Dennis Whyte's presentation at the Tokamak Energy event at the Royal Society. He said that the HTS had changed the game so that instead of fields being limited to a few T (by superconducting transitions IIRC), the field limit shifted to around 22T, and the practic...

Re: High-temperature superconducting tape for magnets at 50+ tesla

"High Temperature" is relative. The paper shows they're working at 30 K and below, and the performance falls off at high current in the 30 K tests. Performance at 4.7 K is outstanding. Liquid nitrogen runs about 77 K, so you don't get this sort of performance at liquid nitrogen temps. Thi...

High-temperature superconducting tape for magnets at 50+ tesla

This should have implications for various nuclear fusion reactor designs:

Re: New John Goodenough battery with high (too high?) energy density

The paper has drawn criticism from other battery researchers, who tell Axios one aspect of the new battery cells — the relative dielectric constant — is higher than ever before recorded in any material known to science. No bold guess that Elon won't get a cell... What makes you say that? From what ...

Re: New John Goodenough battery with high (too high?) energy density

So, not really much new information here. Everything still looks inconclusive and potentially overhyped.

Re: Z-Pinch Renaissance

Looks like they are getting there. Goals for FuZE are: Radius =1 mm, density: n = 2 ×10^24 m-3, temperature: 2500 to 4000 eV at an input current of 300 kA. So far they are at 1–2 keV, and densities of approximately 10^17 cm3 with a radius of 3 mm. This is already a good improvement over ZAP- HD and ...
