Scientists claim to have converted runway noise from airports into pulses, packets of electrical energy, that become useful power - AP.
Researchers are working on methods to convert road vibrations and airport runway noise into usable energy.
University of Buffalo theoretical physicist Surajit Sen and colleagues suggest how altering the shape of grain—to—grain contact areas between the particles underlies this process.
Under “normal” circumstances, when the particles are perfect spheres, exerting force on the first sphere in the chain causes energy to travel through the spheres as a compact bundle of energy between three to five particle diameters wide, at a rate set by Hertz’s Law.
But Sen and his collaborators have discovered that by altering the shape of the surface area of each particle where it presses against the next, it is possible to change how the energy moves, the journal Physical Review E reports.
Sound Energy to Electrical Energy has been technically possible but, so far a Commercially Viable Invention has not been made!
