2. Bioelectricity

Bioelectricity can solve the problem of load shedding. Any vegetable contains a certain amount of organic electricity. Lemons are relatively high in organic electricity. It is then found in tomato and potato respectively. The process of bioelectricity utilization is also very simple. If a copper sheet and a zinc sheet are inserted into the vegetable and connected with wires, it can be seen that electricity is being conducted in the conducting wire. It is possible to light the LED with this electricity. A lot of potatoes are produced in our country.
