Steam-powered iPhone charger
Despite my love of the latest gadgets, I do have a soft spot for old mechanical contraptions such as typewriters, trams, cars and, of course, steam engines. So I am grateful to Engadget for news of the latest development in USB-charging power. An enterprising mechanic has harnessed a small steam engine to a generator in order to produce enough power to charge and run any device that can take a USB feed--including our beloved iPhone. Now this is much more fun than simply plugging the thing into the wall socket. It makes a lovely noise and you really get all the visual and audible clues that your device is being charged.
