Innowattech recently created piezoelectric generators that can be used as normal rail pads, but generate renewable energy whenever trains pass on them. The company tested the technology by replacing 32 railway pads with new IPEG PADs, where the pads were able to generate enough renewable electricity to determine the number of wheels, weight of each wheel and the wheel’s position. In addition the speed of the train and wheel diameter could also be calculated. The company states that areas of railway track that get between 10 and 20 ten-car trains an hour can be used to produce up to 120KWh of renewable electricity per hour, which can be used by the railways or transferred to the grid.
cool very cool,but if energy is reclaimed its always at an loss and a more efficient travel option must be considered but still very cool idea.
