A French design team, ModeLabs, has come up with three Eco-friendly cellphone concepts. One of them is the YoYo Phone which draws energy from bounces and swings and it can also get extra power via the built-in solar cell.
Check out the other two design after the jump.
Another phone is the U-Turn which is a business phone. It draws energy from the opening and closing of the keyboard.
The last one is the Runaway, a sports phone. It draws energy from movements during exercise.
With these three phone, we will no longer recharge our phone in the old way but using our natural movements.
