Flying Wind Farms

Power generation: If people object to wind farms cluttering up the countryside, one answer might be to put them in the air

So, just as oil companies are drilling deeper and in more remote locations in search of new reserves, pioneer wind-power engineers are looking higher in the sky for new sources of energy. Conventional turbines will not take them there—the highest to date is just over 200 metres tall. So they are trying to invent a whole new technology for harvesting wind: electricity generators that fly.

... Mr Shepard estimates these rigs could produce power for as little as two cents a kilowatt hour. That is cheaper than the three to five cents conventional energy generation costs.

Seriously, how cool is that?
