tokamak

By contrast, the JET tokamak in the UK is expected by many to achieve real overall breakeven by 2020.

So far, the net result of the project is that a 6 story Tokamak can't work, due to plasma instabilities.

Only the Tokamak is still here, with the finicky details still being worked out and bigger machines necessary to bring it together.

The tokamak is the fusion community's choice of device for getting energy out of a fusion reactor, but smaller configurations may also be promising.

Before it seemed like the credible effort was the tokamak and everything else was the domain of crackpots.

Which is a really important part of how plasma containment works in a tokamak nuclear fusion reactor's.

Especially since the rise of solar energy (and tokamak fusion and geothermal) means that electricity is going to mostly get cheaper and cleaner in the foreseeable future.

Replacing a micro fusion reactor, while not as bad as replacing a tokamak reactor, is significant.

When it was invented the Tokamak was talked about in similar ways - and a half-dozen more schemes after it.

The project afterwards would most likely be a tokamak reactor or something if i could get the thing working in creative.

It's got the strongest magnetic field and highest plasma pressure of any tokamak in the world, and a couple years ago made a pretty major breakthrough in tokamak physics (I-mode).

I feel that the tokamak eats all official R&D funding in this area (and boy can it eat funding).

From the article: "Until now, the majority of fusion reactor systems have used a plasma control device called a tokamak, invented in the 1950s by physicists in the Soviet Union.

"As Tom McGuire, who is leading the Lockheed team, notes, however, the circular magnetic fields which coil around a tokamak’s doughnut become unstable if the plasma’s pressure is too high."

Engineering problems are very different to "fundamental physics", and there's no particular reason to think that we can't build a suitable neutron absorber for a tokamak, just that it's tricky.

Tokamak is a just a fascinating example.
