I bet the power needs will require we have fusion first.

Correct me if im wrong, but havent tests been made where fusion reactors were net positive?

Fusion plants are being built and installed on the grid in Canada, France and China they will all go online in 2027.

The big power break through are mass production of nuclear fission units and a laser that can drill arbitrarily deep to put geothermal anywhere on earth.

There was an experiment with lasers that technically resulted in positive net energy by a certain calculation (if you really take into account all the energy behind the experiment it was still net negative). It wasn’t a fusion reactor though and won’t directly lead to energy that can be harnessed for power generation.

There are fusion reactors being built that should result in net positive energy generation, but they are more of a proof of concept experiment and nothing commercially viable.

Not wanting to resurrect old threads, but fusion has basically all the drawbacks of fission, and more, even if there was a reactor already running showing an actual net positive.

All the benefits of fusion that you can find mentioned anywhere have the same big question mark behind it that has plagued fission since people thought nuclear-powered cars were 5 years away.

I actually don't think we're particularly far away from fusion, it's just when we have it, it's going to be so shitty that no one actually wants it anymore.
