Do you deliberately avoid visiting friends who live in multi story buildings without an elevator No one would fault youhaving to climb even just a single flight of stairs is like being forced to workout against your will. But thanks to engineers at Georgia Tech and Emory University, stairs might one day do all the hard work for you. In a paper published today in the journal PLOS ONE, that team details their energy recycling stairs, which store energy when you descend, and then release it to make the ascent easier on the way back up. You probably dont stop to think about it while you race down a flight of stairs, but your body expends a considerable amount of energy in the process to prevent you from falling. Its usually wasted energy, but these energy recycling stairs take advantage of those forces using a spring loaded mechanism that compresses each step and locks it down as you descend. This leaves every step charged with potential energy once youve hit the bottom. When you go to climb back up, pressure sensors on each tread release the locking mechanism on the step below it, turning that stored potential energy into kinetic energy that helps lift a climbers leg as the spring powered step raises again. As the stairs compress on your descent, the engineers have calculated they save around 2. And on the way back up, the energy recycling stairs make it around 3. The stairs unique mechanisms can be retrofitted to existing steps, so the technology isnt only for new buildings, necessarily. Simple tips on Attic Ventilation can save hundreds on your energy costs.
