A Potato Battery Can Light Up a Room For Over a Month

A couple years ago, researchers at the Hebrew University of Jerusalem released their finding that a potato boiled for eight minutes can make for a battery that produces ten times the power of a raw one. Using small units comprised of a quarter-slice of potato sandwiched between a copper cathode and a zinc anode that's connected by a wire, agricultural science professor Haim Rabinowitch and his team wanted to prove that a system that can be used to provide rooms with LED-powered lighting for as long as 40 days. At around one-tenth the cost of a typical AA battery, a potato could supply power for cell phone and other personal electronics in poor, underdeveloped and remote regions without access to a power grid. https://www.smithsonianmag.com/innovation/a-potato-battery-can-light-up-a-room-for-over-a-month-180948260/?utm_source=twitter.com&utm_medium=socialmedia A Potato Battery Can Light Up a Room For Over a Month
