Opponents of windmills cite the dangers the spinning blades post to birds, the risk of damage due to storms, and the maintenance required to keep all those moving parts running smoothly. But what if a windmill lacked blades and didn’t move at all?
That’s the idea behind the Delft University of Technology’s EWICON, which looks more like a modern piece of art more than an eco-friendly source of energy.
Also known as the Electrostatic Windenergy Convertor, the EWICON is composed of a steel frame filled with criss-crossing metal tubes that release electrically charged water droplets. As these drops are blown away by the wind a current is produced that can be used to generate electricity. So there are minimal mechanisms to fail, and the EWICON should run absolutely silent even in heavy winds.
