The interesting thing about what they are doing at Auburn is the disruption prevention. Driving the current in a tokamak is one challenge, but that may be partly met by leaning on the bootstrap current to reduce the current drive demand. The other issue is that current disruptions are hazardous and seem difficult to eliminate. The idea with Auburn's experiment is to see whether current disruptions can be either prevented or made less disastrous by incorporating a limited amount of helical shaping to provide some rotational transform to the plasma without current [the two reasons for tokamak currents are (a) ohmic heating, but this is only for startup (b) providing the rotational transform to keep the plasma stable]. That way, if the current starts to quench, the vacuum magnetic field 'catches' the plasma before it totally collapses. Maybe. So it's actually very cool research, and they are still publishing/doing experiments. They are hosting a in February, you should be able to find out more when they post the presentations online

You guys.... I knew most of that already.

I'm really confused what the confusion is. Giorgio, we should continue this conversation on another platform like phone or something. I literally explained everything as clearly as I could. I don't think you understand what I was talking about.

But seriously tho, despite all of the solutions to toroidal magnetic confinement, none of that matters, cus they ultimately can't make a low q net energy small and not complex toroidal magnetic confinement machine. The other paths, like polywell, is still better.

PS: Solo, how you know about stuff Auburn is doing? lol, not many ppl (even in the field) do.

we should move this to another platform, like phone or skype. PM if you would like to continue the conversation, although, there's not much more we can talk about that I havent already covered.

As for no money going into polywell , with a little luck that may change. It has been no secret that Park is beating the bushes for investors, more importantly investors that can see this though to the end.
And now we have this tidbit out of the climate talks:
Gates will announce the creation of a multibillion-dollar clean energy fund on Monday at the opening of a Paris summit meeting intended to forge a global accord to cut planet-warming emissions, according to people with knowledge of the plans.
The fund is meant to pay for research and development of new clean-energy technologies. It will include contributions from other billionaires and philanthropies, as well as a commitment by the United States and other participating nations to double their budget for clean energy research and development, according to the people with knowledge of the plans, who asked not to be identified because they were not authorized to discuss the fund.
So maybe? :wink:

Unfortunately, to date, US money is only interested in the subsidies leveraged returns on solar and wind. They see the argument as a profit margin one. Much more profit to be had when the government is pouring tax money into it to support investment returns.
If fusion ever sees similar support, then I predict the willingness of US investors to fund it will improve accordingly.

that's unfortunate, your loss tho.

What I meant to say is, I covered the points, but you didn't get them. But that's not correct either, I think you just didn't attempt to learn the points I made.

Happens a lot on the internet, complete arguments are cheer picked apart, while the rest never goes through. Not sure what I should do when I repeated all my points twice, lol... what should I do?

this article claims Wenderlstein 7X was the first in the world ever to produce hydrogen plasma? Other fusion prototypes only produced helium plasma. Is there any veracity to that?

http://www.iflscience.com/physics/germa ... orld-first

"Germany's Fusion Reactor Creates Hydrogen Plasma In World First"

"Last December, the team managed to suspend a helium plasma for the first time in history, and they’ve now achieved the same feat with hydrogen. Generating a hydrogen plasma is considerably more difficult than producing a helium one, so by producing and sustaining one in today’s experiment, even for just a few milliseconds, these researchers have achieved something truly remarkable."

Was not WB6 and 7 tested with H2 gas? ie. Generated H2 plasma?
