Getting wind farms off the ground
economist.co.uk
If it ever seems windy where you live, be thankful that you do not live ten kilometres up in the air. At that height the jet-stream winds are stronger and blow more consistently than ground-level winds, and they carry up to a hundred times more energy. 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 tallest to date is just over 200 metres tall. Instead they are trying to invent a whole new technology for harvesting wind: electricity generators that fly.
