Fluxxlab is an NYC-based design firm run by partners Jennifer Broutin and Carmen Trudell that focuses on "sustainable energy harvesting, specifically in the form of converting small amounts of human energy into electricity." Their Revolution Door is a simple concept:
By mechanically harvesting a negligible amount of human energy and converting it to a tangible display through the use of a generator, the Revolution Door will directly communicate a single person's contribution to an energy cycle possible through the metabolic relationship between people, technology, and architecture.
While a revolving door is the most obvious and straightforward way to capture energy, Fluxxlab has also developed the Powerslide concept, which captures energy from sliding doors, windows, and even drawers; and the Door Dynamo concept, a door closer (modified with an energy-gathering component) that can be added to any existing door.
