Extraction of energy using potatoes, nails and a regular calculator is an experiment that youtuber under the nickname Equalo did. He extended his own challenge by starting with a pregnancy test.
This time, youtuber has constructed
a miniature power plant. In it, he used nearly two hundred washed and dried potatoes, nails, wires and a calculator. He recorded the experiment, as expected, on video, and posted it on his channel.
Getting electricity with the help of root crops is familiar to many from the school physics course. The fact is that the inside of the potato contains phosphoric acid in small quantities. And if you combine a young tuber with an object covered with zinc, then a chemical reaction will begin to oxidize and release energy.
Attaching a copper conductor, such as a coin or wire, will create a positively charged electrode. The output is a battery, albeit a low-power one.
Remembering the physics course, Equalo decided to make his idea a reality. And the potatoes did their job.
