I still think that if power satellites can ever be made practical it will be by using O'Neill's approach, but for some reason most modern advocates want to launch everything from the Earth and I don't think that will work. *> IF, we choose to harvest the ocean winds, we have the promise of about > 11 times the potential energy produced by our species, during the year > 2018. What's the big drawback then?* Environmentalists. If it works they will say it would disrupt wind and ocean currents, is ugly, and kills little birdies, and so should be dismantled immediately. The only type of large energy project they like are the ones that don't work.
