The US has lots of desert, and - with the advance of global warming - will probably soon have even more. This land is useless for anything except solar power generation and super- conducting cable means that the power generated there can be used pretty much anywhere. Photovoltaic cells are useless at night, but thermal solar can heat up loads of molten salt during the day and use it to keep generating power overnight. -- Bill Sloman, Nijmegen
