Windlift is a small engineering and computer programming company based in Raleigh, North Carolina. Windlift is developing the next generation of Airborne Wind Energy Systems. Its anchored buoys allow tethered aerobots to harvest electricity anywhere there is wind, on and off-shore. These anchored buoys can be quickly relocated as energy needs change, or to avoid the impact of large tropical storms. Flying at 500-800 feet, the organic flight paths of Windlift’s machines move in harmony with the natural environment, avoiding the negative visual impact of permanent steel structures dotting the landscape and ocean vistas. The elevated vehicles also provide an ideal platform for high-bandwidth communications and local security.
