Did you read the article?
This is one version of solar MDH, magnetohydrodynamic power generation. Liquid metal flowing through a magnetic field generates power. This site I am linking to must be pretty old, it is all HTML, no CSS or anything.

I guess that is supposed to be more efficient than running a steam boiler/turbine but show me the money I don't see any MDH online, do you? There must be some fundamental reason why they never caught on. Some of the original work was done almost 50 years ago.
i think it was probably written by a physicist.
i was thinking of coal-fired MHD. wiki says it's ok for retrofitting old single-cycle plants but not economical for new multi-cycle plants.

yeah, but i wonder how they will scale it up. 3000 deg K inside a nanotube doesn't translate to much outside the nanotube, i would guess.
