Phone running out of charge? Just nip into any public toilet and attach this handy phone charger wind turbine to the hand dryer.-- hippo, Apr 06 2014 I'm not sure I can reliably reproduce an evil laugh for a long enough time period to sufficiently charge the battery.-- RayfordSteele, Apr 07 2014 That is weird, I had the same idea about a week ago...great minds etc-- not_morrison_rm, Apr 08 2014 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.-- xandram, Apr 09 2014 Perhaps then construct a little Rankine engine with a boiler suited to incinerate paper towels.-- the porpoise, Apr 09 2014 Yes, I think that would be an ideal solution-- hippo, Apr 09 2014 random, halfbakery
