One might say that this plan shows at least part of the way forward – little-by-little. Individual schemes like this do very little in the overall scheme of things. But add them all up and you could end up with a significant bit of energy supply; folks with solar panels supplying the grid, wind-generation (once dismissed as trivial, now significant), , geothermal etc. And I speak as a great believer in nuclear power. At least I would be if we could find a way of doing it by people and a system which is not incompetent, corrupt and driven by the need to do everything cheaply and not safely. There remains the hope for fusion in the long term.
