Plan1 Make writer Dave Prochnow shares his experiences living though the Hurricane…By hooking a DC motor to the rear hub of my bicycle with appropriate gearing, I was able to generate a fairly consistent 8V-9V power supply (see Plan1.gif). Don’t take this activity lightly. I’m a vigorous cyclist and skater practicing 50-60 miles per week. Maintaining this amount of power for roughly 30 minutes required a significant effort on my part. As they say, your mileage may vary. Link.
