Over at Inhabitat they posted today on the energy generating revolving door.  If you remember I first posted on this beck in February when it was in the concept stage.  It is nice to see that it is now complete and operational, but I can’t quite figure out if these are two people working on the same idea or did a different company bring this to a working model.  It is not clear on the separate sites or in the press release.

Royal Boon Edam Group Holding has proved, once again, to be the world leader in entrance technology with their latest feature in revolving doors. Boon Edam developed an energy generating revolving door for the Driebergen-Zeist railway station in The Netherlands, which not only saves energy but also generates energy with every person passing through the door.

The door will not only generate energy, it will also store the energy to power it’s generator.  The generator will then control the speed of the door while it is revolving.  Lighted with low energy LED’s, the door will switch to the buildings main power only when traffic is low and enough energy is not being generated to power the lights.

Another cool feature are the LED scales inside the door that indicate the amount of energy that is generated. When passing through the door at a slow speed, the scale will end up in the red or orange zone, whereas a normal or fast pace pushes the scale into the green zone, indicating that significant electric energy is generated. Another LED indicator at the control unit shows when the illumination of the revolving door is powered by human energy, or by the mains supply. “Human Powered Energy” stickers were applied to the revolving door to make users aware of their contribution to this green building. The total amount of energy that is generated by the revolving door is accumulated and shown on a large display inside the building.

A very cool idea that has come to fruition and just one more step in developing self powering technology.  Just think, there is the potential that everything that moves in your home may generate power one day.  WOW!
