Hairy HousesCould the friction caused by wind rustling special filaments together produce useful heat? Wind power is been usefully harnessed but maybe it's full potential has been missed. Wind turbines require winds of a certain strength in order to be able to perform useful work. So consider the vast untapped potential of light breezes which although weaker in strength are by far more constant and widespread. Special filaments
Piezoelectricity is the ability of some materials (notably crystals and certain ceramics to generate an electric potential in response to applied mechanical stress. How much power could a large number of piezoelectric filaments produce in a constant breeze?
