2. Lemon battery - Wikipedia

   en.wikipedia.org/wiki/Lemon_battery

   Substituting a magnesium electrode for the zinc electrode makes a cell with a larger voltage (1.5−1.6 V), and a single magnesium/copper cell will power some devices. [7] Note that incandescent light bulbs from flashlights are not used because the lemon battery is not designed to produce enough electric current to light them. Such a battery ...

   Friction is the least-used of the six methods of producing energy. If a cloth rubs against an object, the object will display an effect called friction electricity. The object becomes charged due to the rubbing process, and now possesses an static electrical charge, hence it is also called static electricity. There are two main types of ...
