The potato battery is a simple electrochemical battery that produces free energy called Potato Powered Light Bulb. It is a common curiosity that how can a potato produce electricity. A single potato can produce few milliampere currents that can power an LED light. Since no external power source is required to get electricity from a potato, due to this reason it can be used as a free energy light bulb. However, a potato cannot be used to light an AC bulb. The free energy light bulb out of potato is not real because it is impossible to get high power electricity from a potato. This potato light bulb experiment shows how people make fake videos as a free energy power source. The real or fake free energy light bulb experiment can be distinguished with the help of this video. A potato can be used as a batter, it is true. But it can produce a very little current that is not enough to power up an AC light bulb.
