Power Generating Slabs: Lost energy conversion of human locomotive force into electrical energy

In the world of modern technology, newer sources of energy and new methods of power generation are two important area of interest for researchers and engineers. Recently a new method is established to generate power from the lost energy of a human during his/her locomotive period. A piezoelectric sensor based costly product is available in some developed countries which can generate power from human locomotive force, but it is not suitable for countries like Bangladesh where power demand is very high but economy is not highly developed. In this paper we will explain the design and construction method of a “Power Generating Slab” which can be used to generate power by establishing anywhere of the walking zone of human (roads, stairs, pavements, dais etc). This is done in a low cost process with locally available equipments (micro-generator, iron plate, rack pinion gear, free-wheeling system, spring etc). These slabs can easily sustain human weight when people walk along them. With a small deformation of spring, the weight (mechanical energy) of a human body is converted into electrical energy by rotating a micro-generator with the help of a `rotating shaft' coupled with it. From each foot step almost 10V-12V is generated. This energy is stored in a rechargeable battery which can be used as a power source to drive loads. Assembly of some power generating slabs can give better result. This is a method which is reusable and it will run for a longer period.
