Flying wing prototype takes wind-power to new heights

Flying wing prototype takes wind-power to new heights: "Wind can be an unpredictable and unstable source of power, and high in the sky where it is more stable, it's difficult to exploit. Airborne wind turbines could provide a solution to this problem, but although the idea has been around since the 19th century, it's never been exploited on a larger scale."
