From prexamples.com – In a timely PR stunt, Vodafone has created Power Shorts, a prototype product that uses thermal energy to charge your mobile if you can’t get to a plug. According to the source (mentioned below) a day’s worth of walking ‘should give a smartphone an extra four hours of charge’, which as funny as the concept sounds, could be pretty useful.
(Update: It was just pointed out to me by @stina_eakins that Vodafone also worked with fashion designer Richard Nicoll in 2012 on a handbag that does the same thing)
