Until December no group able to produce more energy from reaction than it consumes. Lawrence Livermore National Laboratory repeated breakthrough in experiment on July 30. Scientists believe fusion power stations still decades away.

huh... independent replication rarely gets any attention, nice to see a change in that.

This is just the energy going into and out of the pellet. There are still huge inefficiencies in the lasers and cooling systems that mean we can't just hook this up to the power grid right now. We'll need much more efficient lasers first.

Sounds interesting. Is there a non-paywall link available?

Thank you for the link. I'm looking forward to hearing about their "improved version" in 8 months.

*net energy output if you ignore that fact that 100 times more energy was put into the lasers than was released in fusion.

This is a weapon research program with a bit of civilan pr fluff on the side.

What kind of weapon? We already have perfectly functioning fusion bombs.

[–] GigglyBobble@kbin.social 0 points 1 year ago

My guess would be the lasers? Fusion bombs are somewhat cumbersome by not being very precise and world war causing.

countries had perfectly functioning rifles in 1890, didnt stop research into how to make better ones.
