This article aims to develop the electric power generation system of ground mechanical green energy harvesting on sidewalk and perform its working efficiency measurements. The developed system mainly consists of the sidewalk lectric power generation brick and the automatic efficiency measurement system. The sidewalk electric power generation brick used the pulsed electromagnetic induction generator and the general electromagnetic induction generator with suitable transmission mechanism respectively. The pulsed electromagnetic induction generator is built in an electric coil tube integrated with an inside movable induction magnet. Moreover, two push magnets are built on the two endpoints of the electric coil tube respectively. The push magnets alternately move over the endpoints of the electric coil tube and push the inside induction magnet to run through the electric coil to and fro. This action yields induced electromotive force in the electric coil and its output power is independent on moving speed of the push magnets. The general electromagnetic induction generator is the traditional generator. The working principle and the transmission mechanism of the mentioned two generators are both in terms of Faraday’s law of induction and with piston transmission of strokes 5, 7, and 10 mm respectively. For working efficiency measurements, this work used the air pressure driven piston to serve as the input energy and integrated with the CCT Lab. developed automatic working efficiency measurement system. Moreover, the transmission efficiency is finally decided by the difference between working efficiencies of the brick and the generator. The results show that the working efficiency is 1.35% for the pulsed electromagnetic induction generator built brick using impact force of 50 kg with stroke of 5 mm, 5.58 and 14.9% for the general electromagnetic generator built brick using impact force of 50 kg with strokes of 5 and 10 mm respectively.
