Fluxxlab has an idea to harness the "energy" in revolving doors. Already an energy saver compared to traditional doors in office buildings … these could generate significsant power in large building with hundreds of workers.
" … work to date has been focused on sustainable energy harvesting, specifically in the form of converting small amounts of human energy into electricity …"
"… Revolution Door is a modified revolving … a redesigned central core replacing that of any existing or new revolving door, a mechanical/electrical system that harnesses human energy and redistributes electricity to an output, and an output device that maps the harnessed energy … 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."
