Turning sweat into watts

We're continuing to develop options for powering the Nano Membrane Toilet in scenarios where grid power is not available.   The latest option is a bike-generator. The generator is compound by a rear-wheel hub motor, a bike stand, and a 26" wheel mountain bike. After a short testing period, an average power of 82 Watts has been generated while pedalling for 15 min by male students. Nevertheless, a more comprehensive statistical study will be carried out to better characterize the generator and user capabilities. Currently, our efforts are focusing on improving the comfort of the rider and reducing the footprint of the bike.
