>> India barely has power for normal domestic consumption; even in Bangalore, the ostensible "Silicon valley" of India, power cuts for an hour or two is a daily affair. - Thats because India today relies heavily on hydro electric power and does not have as many peaker plants to handle peak capacity loads. One could make an argument that this is a perfect scenario for solar on rooftops (South India is a temperate country and gets lots of sun) generating the needed power locally and feeding the rest back into the grid as a perfect example that would work for India. >> There is also the question of trade balance (presumably with China/Japan as well as upstream Lithium miners) - Those are today's constraints. I am not so sure, these are the same challenges that we would be worrying about a decade from now. Geopolitics and tech. change all the time. >> Environmental solutions, incl. solar, are okay for assuaging the guilt about wrecking the environment (and India is totally wrecked) - Thats true, India today is totally wrecked, but so was 18th century London. You can always get better.
