Why can fruit generate electricity?

Fruit can generate electricity because it contains a lot of fruit acid, which is a good electrolyte. Secondly, the electrochemical activities of the two pieces of metal inserted into the fruit are usually different, and the metal with greater activity can replace the hydrogen ions of acidic substances in the fruit to generate charges and cause voltage changes, thus forming a primary battery.

Under the same conditions, the voltage of different fruit batteries is different, and one of the key factors for the formation of fruit batteries is also the acid content in fruits.

Rotten fruit can generate electricity.

This is a scientific research project jointly developed by Gagamada University in Indonesia and Swedish International Development Agency. Sidi Siam Dia, the project leader and professor of chemical engineering at Gagamada University, told this reporter that she had studied for a master's degree in Sweden. When she was a graduate student, she found that Sweden did a very good job in waste recycling, so she came up with the idea of turning waste into treasure in Indonesia.

20 10 In August, Gagamada University was approved by the local government to set up a factory in Gomariba Market, the largest fruit market in Yogyakarta, and received financial support of 654,380.6 billion rupiah (1 USD) from the Swedish International Development Agency. After about half a year's construction, the trial power generation began on February 10 this year.

Every morning, the workers in the fruit market drive past every booth, put the rotten fruit left over from the previous day in bamboo baskets, load them into cars and send them to the factory. There, a small processor breaks these fruits and sorts them-the solid residue of the fruits is used as fertilizer for the fields behind the market; The liquid extracted from the fruit flows into two underground containers to produce biogas, which is then used to generate electricity.
