Holland's Revolving Door, Using Technology to Combat Climate Change

Well, it would seem that this forward thinking country is ahead of the game once again. A new restaurant situated at the train station in the town of Zeist has been working with the design company Rau in order to reduce their carbon footprint. They’ve come up with an innovative idea in the form of a power generation system fuelled by their own customers - They have installed a generator in their revolving door which converts the energy of people passing through into electricity. Each time you pass through the door you generate enough power to make a cup of coffee. The owners estimate that the door will generate approximately 4600 KWH per year. They are also investing in other ways to reduce their energy requirements such as a special low energy cooling system, a sun collector, and of course the obligatory Dutch windmill.
