Flying wind farms

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.
