Whenever I go to Gym and watch all those people on treadmills, I always think if all this kinetic energy can be converted into electrical energy. It may not be much but every bit counts.
This idea of a shoe charger by a teenager is amazing and should be encouraged in every possible way. It may not solve the world’s energy crisis but it is a right step in that direction. Although a two-hour walk will generate about 10-minutes worth of battery power but it is better than nothing. It will also motivate people to do more exercise. [Via]
