You know how they have chemically pumped lasers?

So it would be awesome to directly pump the laser from H3 fusion.

H3 fusion is actually very easy - I think we could do it today. We just don't have a readily available source of H3 for fuel.

3He fusion is easy—you can do it in a garage with some hacked-together equipment.

However, 3He fusion with net power output is exceptionally hard, even with complete disregard to cost. Much harder than deuterium-tritium fusion. We don't know how to do it yet.

Thanks for the correction. Seems the rosy predictions I remembered are not accurate.
