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. source
