According to Battery.com.cn, Rabinowitch said: "The energy produced by a potato is enough to make a room's LED lights shine for 40 days." The idea sounds ridiculous, but it is scientifically based. They have found a simple and creative way to make potatoes produce energy. Rabinowitch and his team have found that actually starting a potato-powered project in the real world is quite complicated.

In order to make batteries from organic materials, you need two metals: zinc used as an anode and copper used as a cathode. The acid inside the potato reacts chemically with copper and zinc, releasing energy as the electron moves. This phenomenon was discovered by Luigi Galvani in 1780 when he attached two metals to the frog's legs, causing his muscles to twitch.

Potato battery technology

Potatoes are often the best choice for demonstrating this principle in school. What surprised Rabinowitch, however, was that no one used potatoes as an energy source for research. In 2010, he decided to work with Dr. Alex Goldberg and Boris Rubinsky of the University of California. They found that by boiling the potatoes for 8 minutes, they break down the organic tissue inside the potatoes, reducing the electrical resistance and allowing the electrons to move more freely, thus producing more energy. Goldberg said: "We found that we were able to increase the output by a factor of 10, which made its economic cost very cost-effective."

But why is the potato battery not successfully applied? In 2010, 324,181,889 tons of potatoes were produced worldwide. They are the premier non-cereal crops in 130 countries around the world and are an important source of starch for billions of people around the world. Olivier Dubois, a senior official at the Food and Agriculture Organization of the United Nations (FAO), said: “To use food as an energy source, you have to consider whether there is enough storage and whether it will affect farmers who sell potatoes. If there are no problems, then this The idea can be achieved."

Compared to modern technologies such as solar energy , the use of potatoes as an energy source does not seem to be satisfactory. Gaurav Manchanda, who sells home solar systems, says that people are not considering energy efficiency and price, but also about their identity. Basically, they may not show potato batteries to their neighbors. However, it is undeniable that the idea of ​​potato batteries is effective and very cheap. Proponents of this idea will no doubt continue to explore this technology.
