Knee Dynamo Charges Batteries While You Walk
Walking has always been a good form of exercise for our health now it's also a good way to charge our batteries. Luckily, US and Canadian scientists have created Knee Dynamo, a special knee brace that charges batteries while walking. Think of the possibilities.
Imagine walking on a treadmill for just one minute and generating enough energy to power up your cell phone for 30 minutes. Does it make you wonder what an hour's worth of walking would charge or how many mobile phones could be charged during a walkathon?
The knee dynamo contains a generator, an aluminum chassis and an orthopedic knee brace. "Using a series of gears, the knee brace assists the hamstring in slowing the body just before the foot hits the ground, whilst simultaneously generating electricity."
