It's symbolic in the way President Jimmy Carter put solar panels on the roof of the whitehouse, as a symbol of commitment to change. Unfortunately Ronald Reagan showed us what he was committed to when he became president and immediately had them removed. I'm sure the "large display" inside the station probably uses more power than the door generates. But the door is a symbol of commitment to change that sends a message to people. And that's an important message. It’s symbolic, and there is nothing wrong with that.

The resources to produce the generator are incremental to the cost of producing any revolving door. I'd have to agree with Clackpot on the door producing this much energy - I believe it's an overall figure that also takes into account how much energy they save with LED lighting.

Neither does the kind of sloppy journalism that quotes figures such as 4600kWh without even bothering with a back-of-an-envelope verification of the figures. 4600kWh per annum works out at 12kWh per day, 365 days of the year, or a mean 500w 24/7. Which would be roughly the output of one adult pushing the door with all their available strength, all the time, for a whole year, 24 hours a day. Unless there are other details we don't know about it just ain't credible. Have fun. -- Clackpot As has been observed elsewhere, the numbers don’t add up.

The tiny amount of electricity generated will never pay back the electricity invested in producing it in the first place. Its a stupid gimmick. That’s idiotic.
