Sustainable and manageable fusion is the holy grail of energy research, hopefully a reactor of this kind can be built in the next century.
Who knows if we are still around in the next 1000 years maybe someone will have found a way to tap into vacuum energy, or even matter/anti-matter reactors.

Fission has a bad rap from Chernobyl and other minor incidents but modern 3rd and 4th generation reactors are designed so they can't actually melt down under any circumstances. I'm not sure on the waste issues, though it's nowhere as bad (relatively) as current 1st/2nd generation reactors.

I'm curious, does anyone on here actually know what current nuclear waste looks like? Green and oozing out of barrels?
Nope, it's a big block of spent rods, it actually looks quite harmless even though it isn't obviously.

There are some designs are on the table that are even better, thorium reactors don't produce radioactive waste, the waste is actually useful in some manufacturing processes, some use helium as a the heat transfer/coolant instead of using seawater so they can be built anywhere away from water, and probably more designs than i can remember.

The problem is getting funding and approval for new reactors, even the 3rd/4th generation ones because of envirotards (my word for clueless environmentalists) and the people who buy into their crap, even governments. They want us off oil but won't do anything useful, solar, wind and other solutions are good and deserve more research and installations but they can't provide power 100%. France is a good example, 80% of electric from fission, and they have the lowest CO2 per capita of any industrial country in Europe, they even sell excess electricity to Britain and Germany.

All I'm saying is do some reading and research on fission before you so ignorantly dismiss it as unsafe and not needed, it's an ongoing area of research and development, and deserves a better reputation than it has.
