The company Pavegen has floor tiles that when stepped on generate an electric current using an electromagnetic induction coil. They quote that one footstep yields 5 Watts. Question is if the weight of the downward force changes, can the amount of power generated change as well? For example, if the force downward was 10 times greater (200 lb person compared to 2000 lb rock) could the amount of power the induction coil produces increase as a result? Could the properties of the induction coil be changed to yield a greater output?
