Volts & Amps Watts Chart Amp-Hour Chart Watt-Hour Chart

Data captured using software from http://wattsview.com  This graph shows you how many Watt-Hours came from a 20 minute generating period by a 40 year old casual rider who works out 2 to 3 times a week.  The bicycle generator system used was the PPG-R pedal power bicycle generator system.   This measurement is useful because it allows you to compare the power output using the same metrics that the power company uses to charge you for electricity.   In this case the total power output was about 25 Watt-Hours.  If the session had continued on for a full 60 minutes it would have been about 3x the amount the power or 75 Watt-Hours.   Converting this value to KWH  you get 0.075  Since 1 KWH from the power company costs ~$0.10 then you can deduce that one hour of hard work is worth less than a penny!
