The amount of power delivered by the jacket is going to be miniscule compared to what your legs are delivering. (Else you'd see plants and trees running down the highway.) |

Curry, I think that you can recharge a bike battery with a square meter of solar power over time. Just leave it out in the sun. It's unlikely that you wouldn't have to pedal, but you could power electric radio/lights/ whatever. And when the battery is charged, it works like an electric bike. |

//Cost of a 200W (peak capacity) panel: about $2,000. Cost of driving a car instead for 10 miles a week (bike-able distance trips only): $182 per year.//
Seeing an idiot on a bike with a solar panel on his head: Priceless |

Nice calculations, fqhwgads, but this isn't complete. A fully charged battery could deliver whatever power was in it. Although your calculations are valid for an empty battery, the effect of having a full battery is only limmitted by the power that can be stored in the batter. That in turn is limmitted by the weight and size of the battery. |

A 3.5 lb battery from here:

Stores ~ 140 watt hours.
Thus, a fully charged battery can deliver an EXTRA 140 watts (another kick-up) for a whole hour in addition to the solar power boost. You would get a 15 mph run time without peddling for a whole hour, and could cruise at 20 mph with moderate pedalling. |

Is that why something along the lines of 'Day of the Triffids' will never happen? |
