I-Walk

About

Every single person walks almost 2 hours everyday at least either to go to work/home, running or any other habit. My idea concerns about using walking in producing electricity. Smart shoe (I-Walk ) is padded by layer of piezo-electric elements which are electronic elements can transform force/pressure to electricity and that force is created during our foot movement on the ground. We can use that energy in charging phones, power banks, headphones, laptops and etc. Each shoe layer can hold 20 piece of piezo-electric at least ,so we get 800 watt at least and this so near to photovoltaics output of power. Also, This idea is available for car tires. Car tires can be filled by piezo-electric elements and piezo-electric elements shall be installed inside tires and during movement ,the tires touch ground and make force on piezo-electric then force is removed then force occurs and so throughout the tire movement and this process ( force, no force, force and so on) produces electricity almost 20 watt per each element of piezo-electric.
