Ian Jaye, Jovan Popovic and Patrick Houin have gone green by creating an intersection powered by humans. Generating kinetic power from pedestrians crossing a busy metropolitan intersection is an ingenious, money-saving idea.
The trio of college students devised this self-sustaining traffic intersection to help cities save money in energy costs, which in turn benefits taxpayers. If the kinetic energy from each pedestrian footstep could be captured to power LED street lamps, traffic signals, cameras and the local energy grid, cities would be able to drastically cut their dependence on oil and electricity. We have the technology -- it's just a matter of executing this brilliant idea.
