    Has anyone tried building a peltier effect generator for these bikes using the heat from the exhaust pipe versus the 20mph ambient airstream? Should be able to kick out at least 10 watts, say 5 volts at 2 amps or 12 volts at .8 amps.

    Would be using no moving parts and wasted heat energy.

    Can you post a pic or illustration?

    Follow this link and read about the product. They are achieving a 10 watt output with only 212 degrees and a mean temperature difference of perhaps 150 degrees. I suspect we could achieve a temperature difference of 300 degrees or more using the exhaust heat versus the 20+ mph airflow as we ride. I've already sent some information to their development team.

    I don't know what power limitations these devices have but they are worth looking into for our uses.
