The Lotus is a power converter that charges up your mobile phone with just a little twiddle of your thumb.

The Lotus uses nonogenerators that allow you to convert your energy into power for your mobile device. All you have to do is spin the wheel on top with your thumb until your phone charged up and ready to go.

I’m not sure how long it would take to fully charge an electronic device with your thumb, but I’m guessing it would take quite a bit of time. At least it’s good for the environment!
