Sony's self-powered eco-friendly digital camera - X2 Creative @ Space

This digital camera uses the principle of mechanical power generation. As long as you hold the handle, you can generate electricity by rotating the ring part to power itself for taking photos. About 15 seconds of rotation can provide enough power to take one photo. Isn't that very environmental-friendly? This is also the original intention of Sony's odo series design. However, due to the lack of a screen, the pictures taken by this digital camera can only be viewed after connecting it to a computer.
