Here’s how the natural energy cycle works: the sun creates energy when it causes the plants to grow, the plants create energy when they’re eaten by animals, the animals and the plants create energy when they’re consumed by people, and then the people create energy when they do things like open doors. That’s sort of the idea, anyway, and it’s one that New York architectural designers Carmen Trudell and Jenny Broutin have tried to express through their design firm, FLUXXlab. They have created several clever devices designed to convert human energy into electricity, and to educate people on their place within the energy cycle.

The Revolution Door

FLUXXlab’s most talked-about concept is without a doubt their energy-harvesting revolving door. Called the Revolution Door, it will consist of lightweight door panels joined to a central core, which is attached at the top to a circular wire coil array, a rotating magnet array, and a gear/flywheel assembly. When people push on the door panels as they go in or out of the building, the gears will amplify the spinning motion, the flywheel will smooth it out, and the arrays will convert it to electricity.   The inner workings will be visible via a glass enclosure, and the door’s power output will be displayed on an electronic wall display, so users will be aware of both how they’re generating electricity, and how much they’re generating. New York University has provided a grant to get a prototype Revolution Door installed on its campus.

The Door Dynamo

A simpler device, designed for use on regular, non-revolving doors, preceded the Revolution Door. The Door Dynamo, as it’s called, combines a hand-crank flashlight dynamo with an automatic door closer to convert kinetic door-opening/closing energy into electricity. The device was used in a study at Columbia University’s Lerner Hall cafeteria, where the amount of energy harvested by the Door Dynamo was compared to the amount of calories consumed and spent by its users.

The Powerslide

Similar to the Door Dynamo, the Powerslide converts the sliding motion of things like windows, drawers and sliding doors into electricity, via an alternator.

Depending on how busy the building is, the amounts of electricity generated by the Door Dynamo and Powerslide might be relatively negligible. Both of these items, however, were designed as much to educate people as to power their buildings - as it says on the FLUXXlab website, regarding the Revolution Door, “[it] will directly communicate a single person's contribution to an energy cycle possible through the metabolic relationship between people, technology, and architecture.”

For another example of a power-generating revolving door, check out the one developed two years ago by Dutch door manufacturer Royal Boon Edam.

Dig the concept. I have a feeling once we're wearing clothes that generate electricity, using sidewalks and doors that capture energy, we'll feel like we're walking through jello.

Here's a great article explaining the thermal advantages of revolving doors in office buildings: http://www.slate.com/id/2196201/

The intro to this article is in error. Energy can be neither created nor destroyed except in a nuclear reaction which converts matter to energy. So the sun creates energy, but all the other references to energy in the intro are conversions of energy from one form to another.

The writer needs to review the laws of physic.

"Energy can be neither created nor destroyed except in a nuclear reaction which converts matter to energy. So the sun creates energy..." Wrong, wrong, wrong.

Energy can be neither created nor destroyed except NOTHING. Not even in the sun.

And who will enjoy moving any door that moves like it's made from granite?

gmhyde and offthegrid: Every time you exert energy you convert mass into energy- this is possible because in essence all matter is created out of energy. It might not be created in the sense that you're thinking of, but matter does breakdown to "create" usable energy.

also offthegrid: there are regulations which forbid a door from requiring too much force to be opened, so their door would be compliant with those regulations.
