    We'll begin a new thread for the Holy Grail of "infinite" energy hopium, Nuclear Fusion.  Hot or Cold, both are loaded up all the time with total bullshit claims.  In this one, the bullshit claim is "Most powerful energy produced in history".  The "validation" of this claim is that the plasma reached a temperature of 108C.

    This claim relies on the stupefying ignorance of basic science of the reporter, the editors and the readers.  Temperature is NOT a measure of energy, Heat is.  Temperature is measured in Degrees Kelvin, Heat is measured in Joules.

    All they did here was achieve the highest temperature of a plasma confined by a magnetic field in a tokamak, which they did by CONSUMING a prodigious amount of electrical energy to force a fusion to occur, which produced some energy, but probably not as much as the tokamak consumed to reach this temperature.  Even if it was net positive, they don't have a means to harness this energy and convert it from heat back to electrical energy measured in Watts (Joules/sec) where it could be useful.

    They also only kept this running for 30 seconds, which is a pretty long ways from firing up a fusion reactor to run for decades, which it would have to to ever have a shot of paying off the even more prodigious amount of money it would cost to build it.

    The Fusion Cavalry will not be riding to the rescue anytime too soon.
