[Cool Gadgets] -Energy generating Revolving door.

Moving away from a coal based economy is one of the top priorities for many governments. Clean energy is what is being looked at, including wind energy and solar energy. Boon Edam has come up with a very cool idea. It’s the first energy generating revolving door.

This new concept revolving door has recently been installed in Netherlands-based Natuurcafé La Port. Each time a customer walks in or out of this coffee shop, they are doing their part towards a greener world by generating a little bit of energy. The door is expected to generate 4600 kwh of energy each year. This may not seem to be a lot of energy, but imagine if such a door or similar product was installed in a large number of locations.
