What I don't like about fusion technology is that it is still expensive. The technology involved is expensive. We may have abundant energy with it but the expense is still going to give the poor a hard time. Same thing with expensive solar energy.
I've got a better idea than fusion.
My concept simply takes ambient heat energy from matter (gas or water or solids). The matter ends up colder than ambient temperature.
It uses principles of quantum mechanics to achieve "negative entropy" and using my unique concept to do it at a large scale.

It only takes heat from matter like air and by product is simply chilled air.... It is absolutely non-polluting and has the potential to reverse global warming and cause global cooling instead.... The technology would also enable sustained exploration of planet Venus surface since ironically, it is the only cooling method that is fully sustainable and can be fully self-contained in a furnace-hot environment. With the cooling system itself providing the main source of energy.
Eventually, this technology can be used to actively reduce planet Venus surface temperature to pave the way for permanent manned settlement.
