Renewable and smart energy

A company named EnGoPlanet is developing many innovative products in the field of renewable and smart energy. They have installed a street light system in Las Vegas that uses a combination of solar energy and the kinetic energy from pedestrians to charge a battery. When the sun sets the energy that is accumulated in the battery is utilized to power low energy LED´s.

Have a look at this clip that displays how it works.

It´s a very cool and interesting innovation!
