It happens that the electricity has been cut off for various reasons and it must be obtained immediately to recharge, for example, a flashlight or a mobile phone. Or, for example, it takes away from civilization – in nature or on a hike. No need to deprive yourself of the pleasure of using a flashlight or a mobile phone: electricity can be obtained by carrying fruits or vegetables. Let’s find out how.
Is it possible to get electricity from vegetables and fruits
As strange as it may seem, you can get electrical current from raw fruits and vegetables. From school physics class it is known that the process of photosynthesis takes place in plant tissues and it is a source of energy. During photosynthesis, the water molecule is split into oxygen and hydrogen molecules. Hydrogen is also divided into parts – negatively charged electrons and positively charged protons.
And microbiology labs have proven that a living cell is capable of generating electrical energy for many purposes. With the help of electrical energy, the plant breathes, produces oxygen and organic substances. And plant juices are natural electrolytes.
To check this, just pierce the potato with a multimeter. Micro-voltage can be seen on its screen. The same experiment can be done with oranges, apples, lemons. And if you insert a copper or bronze electrode into the potato on one side and an aluminum piece on the other side, the voltage will increase dramatically.
In this design, the anode will be an aluminum or galvanized contact and the cathode will be copper. Electricity will be generated due to the interaction of zinc, copper and acid. Obtaining energy from vegetables and fruits is therefore not a fiction.
How to get electricity from fruits and vegetables
To obtain a “battery” of vegetables or fruits, you must:
- several potatoes (or fruits – apples, oranges, etc.);
- single-core copper wires (the larger their cross-section, the better);
- galvanized and copper parts (nails, screws, etc.).
The main role in this design will belong to the nails (or similar parts). Galvanized material – will serve as an anode, that is, negative contact. The copper parts will serve as the positive contact, i.e. the cathode. If ordinary nails are used instead of galvanized nails, the tension will decrease by about half, but the structure will still work.
The copper wires must be stripped and coiled up to the nail. A copper nail should be on one side of the wire and a galvanized nail on the other. Next, you need to break down the potatoes and sequentially drive nails into them. Also, in each tuber there should be nails of a different pair. Different tubercles are connected by nails of different materials.
Practice shows that from three medium-sized potatoes you can get a voltage of about one and a half volts, which is equivalent to a battery. If you solder the contacts, use a copper wire as an electrode, then even up to 12 volts can be obtained from 4 tubercles. This means that such a plant design is enough to power a flashlight.
However, if you do everything right, you will be very disappointed with the result. The fact is that such a flashlight will shine very weakly. And all this due to the fact that the output will be a very small current. If even a hundred potatoes are connected in series, the voltage will increase, but the current will be small.
It turns out that it is theoretically and practically possible to obtain electricity from vegetables and fruits, but the assembled structure will not be suitable from a rational point of view.
