An episode of Peak Moment TV released late last year features Matthew Corson-Finnerty, pedal-power inventor. Watch the video for a great overview of several human-powered devices, including a bike blender, water pump, grain mill, electricity generator, and a very ingenious straw chopper. (See also The Human-Powered Home for plans on building your own human-powered blender, mill, generator, and pump.) Corson-Finnerty apprenticed with Maya Pedal and now works for Aprovecho in Oregon. He also posts notes from his various home experiments on his blog. Thanks, Matthew, for continuing to innovate and explain pedal-powered machines!
