A scientist at the Hebrew University of Jerusalem has made a surprising claim: boiled potatoes can be used to generate electricity.

Haim Rabinowitch and his team found that when a potato is boiled, it creates a chemical reaction that produces electricity. The amount of electricity produced is small, but it is enough to light a LED bulb for up to 40 days.

Rabinowitch believes that this discovery could have a number of applications. For example, it could be used to power small devices in remote areas, or to provide emergency lighting during power outages.

How does it work?

The chemical reaction that produces electricity in boiled potatoes is called a galvanic cell. The cell is made up of two electrodes, a zinc anode and a copper cathode. The electrodes are placed in a solution of potato juice, which contains electrolytes. When the electrodes are connected, an electric current flow through the solution. The amount of electricity produced depends on the size of the potato and the concentration of electrolytes in the solution.

What are the potential applications?

The potential applications of boiled potatoes as a power source are wide-ranging. They could be used to power:

  • Emergency lighting
  • Small devices in remote areas
  • Portable power generators
  • Toys and gadgets

What are the challenges?

There are a few challenges that need to be addressed before boiled potatoes can become a viable power source. One challenge is the process of boiling potatoes is energy-intensive. Another challenge is that the amount of electricity produced is relatively small. Finally, the technology is not yet fully developed.

Overall, Rabinowitch’s discovery is a promising one. It could lead to the development of new and sustainable ways to generate electricity.
