Jerusalem researchers have developed simple, sustainable organic batteries that are powered by potatoes.
Thus, the boiled potato or other similarly treated vegetables could provide an immediate, environmental friendly and inexpensive solution to many of the low power energy needs in areas of the world lacking access to electrical infrastructure. The long-keeping humble potatoes in particular are a good energy source since they are produced in 130 countries over a wide range of climates, from temperate zones to the subtropics- more than any other crop worldwide, but corn, and thus available year round almost anywhere.
