The hating on solar is getting ridiculous and fake-factoidy. Is this 1994 and are we all getting lollipops from the Heritage Foundation?
From a power-generation standpoint, if it makes a profit, it makes sense to do it. The price of generation for panels and thermal is already well past the breakeven point. Transmission is an issue only in the sense that none of the easily workable ideas for long-distance transmission with minimal loss have been tried yet only because no one has absolutely needed to actually do it. It would be handy to have that capability in current grids and we should try out the technology, but the reasons we haven't done it yet are political, not rational.
From a geopolitical standpoint, decentralized harvesting of solar (and wind and other renewables) is almost the exact reverse of petrodollar fuckery. Construction and maintenance alone spreads population out and reduces the choke points for economic man-in-the-middle attacks. The local population needed to run the arrays would rely on the power generated and the local security needed to live, so simple democracy by the people that live in the shade of the arrays should suffice. The dumbness of saying that this is exactly like oil infrastructure shouldn't need to be pointed out, but here ya go.
From a climate perspective, shading the blasted wastelands and dry bush of the American Southwest, Sahara, Arabia/Mesopotamia, Australia, and southern Africa, is nothing but a win when we're looking at thermal manipulation of climate against the trend.
Generally, I don't see anything about this idea that is impossible or actually makes the world worse. Since this idea was first put forward a few years ago, the bullshit attacks on it have relied on childish derision. The worst thing you can say is that it probably won't be the only way we will generate energy. Gasp. Better stahp dis naow.
