I must agree with Brian et. al. Regardless of whether the capital cost is $200/kw (my guess-timate) or $60/kw, I know of no other power supply option that comes close to these low costs (both are dang low).

AND…we all agree operating costs will be relatively low. We just disagree on how low. But, if FF becomes technically possible, I see no reason that it shouldn’t totally dominate the electrical power and industrial process heat markets.

If FF becomes technically possible, wind, solar (except for small remote applications), wave, tide, geothermal, and of course conventional steam turbine (whether fossil fuel or fission heat makes the steam) are all dead end technologies.
