OK, here's something big and way out there: A global power station that taps 'natural' electricity in the ionosphere. Unlimited free power, already in the form we need. No emissions, no need for mining or damming or drilling. And the term 'aurora power' has a really nice ring to it. In more detail: a few days ago on HN there was an article (https://news.ycombinator.com/item?id=23580362 https://news.ycombinator.com/item?id=23580362) about the risks of solar storms and EMPs on America's power infrastructure. Solar storms induce potentially huge electrical currents in the power grid. Rather than regarding it as a danger, why not find a way to harness it? The Amateur Scientist column in Scientific American had a lovely article about electrostatic motors, powered by the Earth's electric field: https://www.scientificamerican.com/article/the-amateur-scientist-1974-10/ https://www.scientificamerican.com/article/the-amateur-scien... (Search for the article title, there's a PDF available elsewhere on internet) The SF writer Murray Leinster made extensive use of ionospheric electricity in many of his novellas... This is a civilization-changer. Like I said, big.
