Energy Harvesting via Magnetic Levitation

Energy Harvesting via Magnetic Levitation

This renewable energy concept captures vibrational kinetic energy from vehicular traffic or pedestrian footfall through an electromagnetic transduction mechanism. A rare-earth magnet array is suspended within a coil assembly via repulsive magnetic levitation, eliminating mechanical friction and enabling sensitive response to minute excitations. When base vibration induces relative motion between magnet and coil, Faraday's law generates an electromotive force across the winding terminals. Multiple generator units are arranged in array configurations beneath road surfaces or flooring panels. Power conditioning circuitry rectifies and boosts the irregular AC output to charge supercapacitors or batteries. The project models energy conversion efficiency as a function of magnet geometry, coil turns density, and excitation frequency spectrum.
