From the previous experiment: &quot;To produce the 2.05-megajoule shot, the laser system required 300 megajoules of power, Kim Budil, director of LLNL, said in a press conference today.&quot; [<a href="https:&#x2F;&#x2F;techcrunch.com&#x2F;2022&#x2F;12&#x2F;13&#x2F;world-record-fusion-experiment-produced-even-more-energy-than-expected&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;techcrunch.com&#x2F;2022&#x2F;12&#x2F;13&#x2F;world-record-fusion-experi...</a>]

The benefits of fusion power will come from <i>continuous</i> power output, rather than a bunch of one-off miniature bursts of fusion.<p>This experiment is very like a very, very, very tiny hydrogen bomb. It definitely produces fusion energy but not in a package that&#x27;s useful for the real world. An analogy would be a car designed to be driven by tiny explosions of TNT rather than a tank full of petroleum fuel.

Useful AI, a room-temperature superconductor, a cancer pill, and now net-positive fusion. Did we just crack open some secret alien tech? Maybe a time-tracker left their toolbox behind?
