Scientists at NASA have sent a man to the moon – now they want to put turbines in the sky too.
The US Government researchers are developing a new prototype of sky-high wind turbines, according to reports. The new wind system is expected to be more efficient than land-based turbines.
The airborne wind-power systems will have two parts – a set of turbines built into a kite-shaped device, which will generate electricity and a ground-based generator linked to the kite, which will be powered by its motion as the wind blows.
Compared to traditional land-turbines, the airborne system can go much higher, up to altitudes where the wind blows faster and more steadily. It is reported to be 90% energy efficient and the design of the turbine blades is expected to allow it to spin faster and further from its hub, which should produce more electricity than land turbines.
NASA will be testing the prototype at 2,000 feet, which is believed to be the perfect altitude for airborne wind-power systems.
