So you fire some nano-bots at any large enough asteroids and they construct these large blades and a dynamo and microwave transmitter on the asteroid then when it hits earths atmosphere it generates energy which is sent to ground stations by microwave? If you have the technology to harness asteroid energy then you have the technology to use coal cleanly. In fact we already have the latter, what we lack is the motivation.
The world is not short of energy sources, the world is short of energy sources that are cheaper than fossil fuels processed the dirty way. The spike in oil prices a year or two ago made a massive difference to the alternative energy industry. If the US could just get up the guts to tax oil, we would be far closer to cleaner energy. Forcing fossil fuel processors to use cleaner methods would have doubly beneficial effect ie higher prices for the end product and less pollution during processing.
Windmills on asteroids is the sort of thing that the US government would love because it, like the 'hydrogen economy', can be used as an excuse to spend many years doing useless research whilst slowing down more practical changes.
