Every once in a while a cool new invention pops up that makes the most of personal kinetic energy – things that create power from your movement, and transfer it to your iPod or cell phone. But now this idea is being expanded on a much larger scale to use everyday human movement to power the world around us. 
Every once in a while a cool new invention pops up that makes the most of personal kinetic energy – things that create power from your movement, and transfer it to your iPod or cell phone. But now this idea is being expanded on a much larger scale to use everyday human movement to power the world around us. The first example is a revolving door which, over a year, will generate enough energy from people passing through it to power the equivalent of 5 homes. Another example of this type of human power generation can be found at some gyms. One in particular has found that by outfitting 6 of their cycles and one of their ellipticals, they’ve been able to cut their power consumption by 50%! Imagine how much energy we exert around us that one day soon will get to be reused.
