What about thorium schemes Dr. Standish? Also, are things such as hydroelectric reservoirs built on the ocean, and lifting sea water as pumped storage workable, or is it an energy sink, where we expend more energy then we produce to accomplish this? My scheme would be to use Canadian Slowpoke reactive reactors, to lift ocean water, on to use billions of litres to drive turbines,as needed. Unworkable, or plausible?


Well that reactor still depends on uranium from fuel and I don't think it's a breeder reactor. Also it's not clear whether they can be scaled up to city-power size. Using pumped water storage has worked well some places where there was a large elevated reservoir available. I don't think it's practical if you have build elevated tankage.

For all the arguments pro and con nuclear fission, including an
impassioned speech by a 16 year old last night to a UN Youth Voice
competition, what never seems to be discussed is the elephant in the
room of how much uranium resources we have. IIUC, if all fossil fuel
power plants were replaced by conventional fission reactors, we'd burn
through our uranium supplies in about 50 years flat. So fission
reactors do not solve the problem. Of course there is fast breeder
technology, but everbody is so shit scared about all the plutonium that
would then appear on the market, making it incredibly easy for rogue
states to construct nuclear weapons, that I don't see that happening
any time soon either.

Cheers
