As there is increased awareness of global warming and its consequences, several companies are coming up with alternative energy and solutions that reduce carbon emissions. Well, alternative energy is a rising concept and it uses an energy source instead of fossil fuel.
Pavegen is a UK startup, which has created futuristic concrete pavement that captures the movement of the people who walk on it, capturing the energy of footfall. It uses a set of triangular composite tiles that rest on electromagnetic generators. Each footstep on a Pavegen walkway generates 2 to 4 joules of off-grid electrical energy or up to 7 watts of power for the duration of a footstep. Bluetooth beacons in the system connect to smartphones too, rewarding pedestrians for each step they take.
