    *Edit: OK, so this article is missing a bunch of vital context. Here’s a better one: https://arstechnica.com/science/2023/08/physicists-achieve-fusion-net-energy-gain-for-second-time/

      The key words are “delivered to the target”. They use WAY, way more power than they deliver to the target, so if you take the energy generated divided by the total energy used, the number is WAY, way below 1. Probably a fair bit below 0.1 too.

      That’s pure laser energy, not whole system energy. Yeah, they got a slight gain from the fusion output, but nowhere near what the whole experiment used.

      The laser energy. All the energy to make the situation happen is significantly higher. It’s sneaky.
