ZEIST – At a café in the town of Zeist, the patrons are generating electricity by means of a revolving door.
Guests entering the café, a former station buffet, can check on a gauge how much power they have generated. One person entering the café generates enough power to make a cup of coffee.
Nature café La Porte says this is the first time a revolving door has been used in such an environmentally friendly way.
