Engineers at the University of Michigan have discovered a new way to generate energy.
A new energy-capturing knee brace can generate enough electricity from walking to operate a portable GPS locator, a cell phone, a motorized prosthetic joint or an implanted neurotransmitter, research involving the University of Michigan shows.
If you can generate that much energy by having an adult walk 2.2 miles an hour (which is not brisk at all), we could end the energy crisis if you hooked every middle school boy in the US up to one of these.
