The Netherlands based company, Royal Boon Edam Group Holding, has created the world’s first energy generating revolving door that is currently installed at the Driebergen-Zeist railway station in Holland. The door stores power generated in a capicitor bank and illuminates LED lights in its ceiling, while a large scale display outside the building shows pedestrians how much overall power has been generated by the door. This commercialized door is not to be confused with the “Revolution Door” project which still remains a prototype.
