We have a man at our work who has an infectious enthusiasm for new ways of creating electricity.
Much fun has been had proposing all sorts of wild schemes involving kites and so on. I have a digital camera that can take movies, so I decided to experiment with it to present one of my ideas. A patent search revealed some similar ideas, but not precisely this one. I'm not sure on the business with patents, but I think that seeing as this idea is now out in the wild, no one can patent it.
It would be nice if someone with a bit of money and enthusiasm picked it up and ran with it.
The idea is very simple. You have a series of windmills, held aloft by a balloon, but they are better than a similar size at ground level, because the winds are faster the higher you go.
