Phone running out of charge? Just nip into any public toilet and attach this handy phone charger wind turbine to the hand dryer.

I'm not sure I can reliably reproduce an evil laugh for a long enough time period to sufficiently charge the battery.

As long as there is a hand dryer in there! Here in the US, so many places are going *green* and will only have brown(recycled paper) paper towels available! [+] If available.

Perhaps then construct a little Rankine engine with a boiler suited to incinerate paper towels.

Yes, I think that would be an ideal solution
