There has been a spate of pedal power projects in the re-innovation workshop recently.
This post shows one recently built for Nottinghamshire Healthcare. The pedal generator was designed as a challenge with a twenty second test to see the amount of energy the cyclist can generate. It also needed to be relatively portable (to fit within the boot of a car).
The systems consist of:
- a shunt regulator (rated at 400W) to dump any excess power
- a LED bar graph display as a visual read out of power generated
- an LED display which shows the actual power output in Watts
- a 20 second test display with an output in Watt-seconds
