People have to learn how to harvest power from fusion before.

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.
