A power road by harvesting electromagnetic energy from moving object

Abstract

There is a large amount of electromagnetic energy in modern life, but how to utilize the wasted electromagnetic energy from moving objects is still a difficult problem. Here, four 28 W fluorescent tube lamps can be lighted up when a car model slides on a simple power road (SPR) with an instantaneous power density of 11.6 W/m2. An energy-velocity model was proposed to utilize the electromagnetic energy in the constantly friction between the SPR and the car model. It was found that the electromagnetic energy generated by an object moving at a low speed increases with its speed. Besides, the instantaneous power generated by an object in a high-speed collision also increases rapidly with its speed. Moreover, the first SPR was successfully built in an actual road, which opens the door for solving the energy crisis. The energy-velocity model can be also used to explain the signal interference of high-speed railway and improve the positioning accuracy of missile, considerate that the electromagnetic energy produced by the object in motion. The new discovery may contribute to modifying the existing collision theory, conservation of mechanical energy, friction theory, Maxwell's equations, and electromagnetic technology.
