That's HOT! 1,472 degrees Fahrenheit. Are there known materials that can maintain their integrity while being constantly exposed to that kind of heat for the expected lifespan of the reactor?
That new material OBAMIUM (an amalgam of bull shit, highly concentrated hydrochloric acid and bile) is capable of ignoring that sort of “heat” for decades.
The expected lifespan of such reactors is quite short, due to the problem of containing extremely corrosive materials at very high temperatures.
This is the kind of problem that Engineers love and solve in the normal course of their profession. Turn them loose on it and they will come up with solutions.
A world without OPEC or any similar cartel is possible and could be made real in an astonishingly short time frame.
