Students at Davidson College, including Alexis Valauri-Orton, will work to retrofit three elliptical machines in Davidson College���s highly trafficked fitness center in order to make them energy-generating. The energy students put into their workouts will be captured and fed back into the building���s power supply. The goals of this project are twofold. First, it will reduce Davidson College���s carbon footprint by harnessing energy and reducing dependence on outside energy sources. According to ReRev, a ���typical 30-minute workout produces enough energy to power a laptop for one hour, or charge a cell phone six times.��� Perhaps more important is the educational component; when students work out on retrofitted machines they will see how much energy they are generating and gain a more intimate understanding of just what it takes to power their lives.
