The world's biggest experimental nuclear fusion reactor in operation was inaugurated in Japan on Friday, a technology in its infancy but billed by some as the answer to humanity's future energy needs.
The method they used is absolutely unsuited for power generation, they’re doing weapons research. Two things:
Sure, more energy came out than hit the target but the amount of power wasted generating the laser light is right-out astronomical. People also gripe about other experiments not including those external (to the reaction) factors but then they’re also generally magnitudes lower.
The targets are very very hard to produce, and you only get to shoot at them once.
