Of course, having a pedal generator is only interesting if you actually pedal it to generate electricity! I'm sure you would like to know what kinds of devices can be powered directly by the pedal generator, and how much pedaling will be required to power those devices. Here are some examples. In each case, the device was functioning. In other words, the Televisions had pictures, the vacuum was running, the air compressor was running, and the heating element in the coffee maker was on. The coffee maker was the most challenging. It would have been quite a workout to make a cup of coffee.

Here are the circuits I used for the experiments...

Pedal Power News Flash

I just finished a test I have been wanting to try "forever."

I directly pedaled a laptop!!!

Here are the specs:

  • PPPM - nothing special; parts as outlined in the plans.
  • Generator - as in the plans.


  • IBM Thinkpad model 2373, with battery (Says "T40" next to the screen. This laptop is a few years old.)
  • CPU: Pentium M
  • RAM: 1GB
  • Hard Disc: 42GB
The test:

First, I pedaled the Ultracapacitor up to 13 volts DC. The DC-DC converter was plugged in during this time, and the green light came on at around 7 volts.

I stopped pedaling at 13 volts. I dismounted, plugged in the laptop, and pressed the power button. It booted immediately! The Ultracapacitor voltage began to drop slowly. It took about 30 seconds to go from 13v to 12v.

At 12v I got back on the PPPM and started pedaling again. I pushed a bit to get the voltage back to 13v and then cruised at that speed, holding the voltage at 13 volts while the laptop finished booting.


So there is an example of powering a laptop with the PPPM - a total success.

In the table below, you will see "Effort" listed. Check the PPPM Science page to see specific data relating physical effort to power levels.

Here are the stats for the laptop, and other devices:
