Revolving door generates power for cafe

The owners of a Zeist, Netherlands, cafe said it has become the first to use its revolving entrance door to generate electricity.

Nature cafe La Porte said patrons using the revolving door can look at a meter telling them how much electricity their entrance generated for the establishment, Expatica reported Thursday.

Workers said one person entering the store through the revolving door creates about enough electricity to prepare a single cup of coffee.
