Cell phone dead? Spin this to recharge!

Fully Analog Cellphone Charging

This Mechanical Cell Phone is by Mikhail Stawsky This phone can be spun around the finger to recharge the battery. I really like this concept. All you need is a little energy that you create and it is translated to the cellphone. Beautiful concept and Design!

I found another interesting design that used solar energy. The design incorporated a sticky suction over the solar panel to adhere to windows for ultimate sun exposure.

Sticky Phone

I think this is a great direction In electronic design but this is impossible to charge at night
