Potatoes do power a potato for a room with LED lights for 40 days

Through the simple method, the humble potato can be made into a battery, the potato can really become the source of household electricity in the future?

A potato can be used for a room with a LED bulb for 40 days

For potatoes, different people may have their own favorite cooking methods, but Haim Rabinowitz (Haim Rabinowitch) would like to go further. Over the past few years, Rabinovitz and his colleagues have been pushing the idea of a "potato power" to try to get people to abandon the use of power grids. They claimed that the use of simple and cheap metal, wire and LED bulbs, can provide lighting for remote towns and villages around the world.

Potatoes power generation plan

They found a simple, but very clever way to make potatoes power. Rabinovitz, from the Hebrew University in Jerusalem, said: "a potato is enough to provide 40 days of electricity for a room's LED bulb. This argument seems exaggerated, but in fact has a reasonable scientific basis. However, Rabinovitz and his team have found that the real potato power generation applications to real life is much more complicated than the beginning of the look.

In Rabinovitz and his team found that potatoes can produce extraordinary power, high school physics courses are still teaching the mechanism of battery work. When you make an organic material into a battery, you only need two pieces of metal, one as an anode, and the other as a cathode, a positive electrode, such as copper. The acid inside the potato will react with zinc and the chemical reaction. When the electrons flow from one end to the other, the energy is released.

In 1780, Luigi Galvani (Luigi Galvani) discovered the mechanism, he will be two pieces of metal connected to the frog's legs, causing the frog muscle twitch. This "animal electricity" can also be reproduced in vitro, you can put a lot of other substances between two metal electrodes, the same effect. Alessandro Volta (Alexander Volta) with the time of the is the use of paper soaked in salt water. Some people have made a "mud battery", using two pieces of metal and a pile of soil, perhaps with a bucket of water.
