Nuclear fusion: is the hype justified?

Date:

Lately, reports have been pouring in of groundbreaking successes in the field of nuclear fusion. Is the golden age of unlimited energy approaching? A little skepticism is in order.

In America, for the first time, more energy has been extracted from a fusion reaction than was put into it. 0.8 kilowatts were extracted, about 0.5 kilowatts flowed in. That initially sounds good and sounds promising. Unfortunately a sham, because the 0.5 kilowatt comes from the hundreds of times the power used to drive the many laser cannons that make possible the result: they all fire a tiny pellet of fissile material at the same time – it gets so hot that the atomic nuclei fuse in it. This releases energy.
