Latest Invention: System that Converts Energy from Tramping Feet into Electricity


British scientists are working on their latest invention - a system able to use the "boot force" in order to power various electronic tools, including torches and radios used by military troops. The system would make the backpacks of soldiers considerably lighter. The devices currently developed by experts from the University of Leeds will generate electricity from the energy of flexing knees and tramping feet.

Their latest invention will eliminate the necessity to carry heavy batteries, thus reducing the weight of soldier's backpacks by up to 10 kilograms (a typical backpack weights about 75kg). The latest invention developed by the British scientists takes advantage of high-tech piezoelectric transducers that produce electrical energy from mechanical stress. Besides the technology is eco-friendly. You can find more inventions here at - check the links at the bottom after the story.

The system, which is part of "battery free soldier" program, represents a two-year project supported by the Engineering and Physical Sciences Research Council (EPSRC) and the Defense Science and Technology Laboratory (DSTL). Researchers look forward to create similar technologies based on other alternative sources, such as solar power and body heat.

If you think this invention is important vote for it.
