The pedal powered laptop charging station and energy demonstration device.
I led a group of students from UC Davis in an Action Research Team for the Education for Sustainable Living Program. The ART was put together to idenifty a need for a pedal powered machine on campus and then to design, construct, and implement the machine. The students decided to build a pedal powered desk that would allow students to power their laptops while working at a comfortable desk enviromment.
