Here are some good news: Researchers have discovered that a potato boiled for eight minutes made a battery that produced ten times the power of a raw one. Haim Rabinowitch, an agricultural science professor, and his team found that using small units made up of a quarter-slice of potato set between a copper cathode and a zinc anode connected by a wire can provide a room with LED-powered lighting for as long as forty days. A potato could supply power to personal electronics at around one-tenth the cost of a typical AA battery. Wow, just think of all the opportunities this could offer to people in the underdeveloped and remote regions of the world.

The potato battery kit includes two metal electrodes and alligator clips and is easy to assemble. Certain parts, such as the zinc cathode, can be inexpensively replaced. Alligator clips that transport the current carrying wires are attached to the electrodes and the negative and positive input points of the light bulb. Kerosene lamps used in many developing parts of the world are approximately six times the costs for equivalent lighting provided by the potato battery.
