It’s Britain, they aren’t feasible in a double entry journal. What is feasible is taking Portugal and sticking mass fields of the things all over it to catch their useful sun and then pumping it all round Europe to feed everyones needs. Tidal power isn’t feasible either, me and a mate worked out we need 24,000 kilometers of that snake like device to cope with the 12% figure of green power needs the government has to reach.
BTW, we ‘need’ 4 to 5 nuke stations right now to keep on top of power needs. The public keep saying no to planned proposals. The government is going to get them in any way they can. But think ahead to electric cars. If we switch over we need 45 new nuke stations to cope with the power needs of them. The public will not accept this. China is sticking in 80 right now, although I originally heard they were going for 100-120.
