Using Air to Recharge Your Cell Phone
sanspeak writes "Now you do not have to look for a power outlet to charge your cell phones. Department of Industrial Design at Indian Institute of Technology, Delhi have come up with a mobile turbine which generates around 3 to 4 watts of energy - sufficient to charge a mobile phone. It costs around $4, fits in your pocket and runs on air ;-). What else do you want ?"
Why not use Faraday's Principle of Induction like these LED torches or a windup charger? Both are independent of external factors.
Hanging out your phone from a car, bus or (shock!) train is pretty dangerous stuff, maybe superman will find this thing handy.
I hope they haven't patented this technology yet, 'cos I'm rolling out my air-powered fan next month.
Rock that crushes, Paper & Scissors that don't matter.
Why? Because people are suckers.
