Jump on that bike and power up the blender for your morning smoothie! Matthew Corson-Finnerty shows several machines he has developed while at Aprovecho Center in Oregon. Watch us pedal power an electricity generator, a grain mill, a blender, and a straw-chopper. Matthew notes there’s “considerable difference between the power that one person can generate, and [what’s] generated by a fossil fuel engine or a coal-fired plant to provide electricity.” After watching these machines, what do you think?
