The charging shoe is made in Kenya by a young inventor, Anthony Mutua (24 years old). The idea is to use the energy created by the movements of our body to generate electricity that can thus recharge batteries of mobile phones or other electronic devices.
The battery is placed in the sole of the shoe and the piezoelectric system bustles at every pressure of our foot on the ground and produces a renewable energy without paying out the slightest centime.
To tell the truth, there are two ways of collecting the energy: connect directly the device to be recharged to the shoe via a rather long cable so that the device in question can be placed and hold in a pocket, or keep the electricity generated in the battery in the system to recharge it once seated.
