Each clonk of a hiker's releases enough energy to illuminate a light bulb. In order to make use of this power, Matt Stanton, who is an engineer and a wishful hiker, created a shoe so as to make store that energy. The insole stores the energy as electricity. Electronic devices are charged with the help of USB cable. The device assures to be much more effective then the traditional and powerful power packs as well as solar chargers, which works slowly as well as their performance depends upon the weather.
Instead of using bulky methods of generating electricity, Stanton with Hahna Alexander put some efforts to make it slimmer as well as more efficient. It took 3 years to create the SolePower System. The pair is shrunk down components similar to those found in hand-cranked flashlights. This results in a standard-size removable insole that weighs less than five ounces, including a battery pack.
The device requires a lengthy 15-mile walk to charge a smartphone. But Stanton says the company is working towards a newer version that can charge an iPhone after less than five miles of hiking.
SolePower is going to release it's current version later by this year.
Working:
1) A gear converts the energy of heel strikes into rotational energy, spinning magnetic rotors.
2) The motion of the rotors induces an electrical current within coils of wire.
3) Electricity travels along a wire and into a lithium-ion polymer battery pack on a wearer’s shoelaces.
