A stomping crowd will give the country electricity

    MIT students found a new source of electricity - a crowd of trampling people. Indeed, such crowds are constantly present, for example, at train stations, stadiums, markets and universities, so that with the appropriate conversion of the floors, you can turn the same station into a powerful electric generator.

    Crowd Farm operates with a variety of tectonic blocks that are mounted on a platform and moved under the influence of the weight of people passing through them. The blocks are close to each other, and electricity is generated due to the movement of the internal rods relative to each other (see diagram under habrakat).



    One human step generates energy, which is enough to burn a 60-watt bulb for a second. Of course, you can’t put such a system in an apartment, but at a busy station it’s just gigantic power. So, for the movement of a powerful locomotive requires only 28 527 steps per second.



    The student-developed system won first place at the Holcim Foundation's Sustainable Construction engineering competition this year.
