Research has found that a potato that has been cooked for eight minutes creates a battery 10 times more energy than raw.
Haim Rabinovich, professor of science and agriculture, conveyed an experiment with potato slices rooms, placed between the cathode and zinc anode copper, which were then connected with wire. It was found that these units can light up a room with LED light, for up to 40 days.
This discovery is very important not only for the scientific world, but also for the underdeveloped regions of the world, offering many opportunities and possibilities.
The only question at this point is: Why potatoes, and not some other vegetable
Two reasons: potatoes can grow (almost) anywhere in the world, including climate tropical and subtropical, and can be found in abundance everywhere.
In this particular case, the potatoes are not the source of energy, which only act as the connection or bridge between the metals, which allows electrons to run through the cable, thus providing electricity.
