It should be possible to power a small power source with body heat (using thermoelectricity, try a Peltier in inverse mode) or pyroelectricity, but I'm rather betting on pezoelectricity. It is only a question of time until some LED blinking sport shoes are powered with a piezo flexing foil. Now getting the power to your fannypack will require some copper in your trousers... > Ive seen some mention of using solar cells but I might be able to suggest > a somewhat cheeper alternative.

I havent been able I presume you mean CuInSe_2 (actually Mo/CuInSe_2/CdS/ZnO) cells.
