Citat: "...
a prototype called the Dynomak was recently built by Jarboe and doctoral
candidate Derek Sutherland, who had previously worked on reactor designs
at the Massachusetts Institute of Technology (MIT).
...
"We eliminated the need for the expensive superconducting toroidal field
coil set like the ITER in France requires, enabling us to make a much
more compact reactor system that reduces the cost by a factor of 10
while increasing the output by a factor of five," Sutherland told EE
Times. "The spheromak design generates twisted magnetic fields which
drive a current in the plasma -- which is a really good conductor --
thereby confining and stabilizing the super-hot plasma in the reactor. A
voltage transferred using induction generates these magnetic fields to
achieve confinement and stability."
...
It will take about about 73 megaWatts to keep the final gigaWatt Dynomak
running in a steady state.

[Fra kommentarer:]

Our claim of the possibility of fusion cheaper than coal is backed by
scientific papers in top journals.
A cost effective controlled fusion configuration call the spheromak has
been efficiently sustained while stably confining high pressure fuel.[1]
The new sustainment method [2] may lead to fusion power that is cost
competitive with coal.[3]
