You can generate electricity by building a small power plant at home. All you need is carbon, Teflon tape and a pencil.

Ecole Polytechnique Fédérale de Lausanne is the inventor of this device. It is cost effective as well as environment friendly. Besides, this tiny power supply will do the same thing as two AA batteries.
