What fruits can generate electricity? Why do fruits generate electricity

Fruit can actually generate electricity? The power generation efficiency of different fruits is not the same.

The reason why fruits can generate electricity is first and foremostFruits contain a lot of fruit acids, which is a good electrolyte; Secondly,The electrochemical activity of the two metal pieces inserted into the fruit is usually different, in which the more reactive metal sheet can replace the hydrogen ions of the acidic substance in the fruit, which can create an electric charge, causing a change in voltage, so that a galvanic battery is formed.

Under the same conditions, different fruit battery voltages are different, and one of the key factors in the formation of fruit batteries is also the acidic content in the fruit.

Rotten fruit generates electricity

This is a research project developed by Gagamada University in Indonesia in collaboration with the Swedish International Development Agency. The person in charge of the project, Sidi Siamdia, a professor of chemical engineering at Gagamada University, told this reporter that she had studied for a master's degree in Sweden, and during her graduate studies, she found that Sweden had done a very good job in waste conversion and utilization, so she came up with the idea of turning waste into treasure in Indonesia.

In August 2010, after obtaining approval from the local government and funding from the Swedish International Development Agency (SIDA) of IDR 1.6 billion (US$1 is about IDR 8,800), Gagamada University set up a factory in Gomaliba Market, the largest fruit market in Yogyakarta. After about half a year of construction, trial power generation began on February 10 this year.

Every morning, workers at the fruit market drive past each stall and load the rotten fruit that the vendors have placed in bamboo baskets and carry them to the factory building. There, a small processor breaks up and sorts the fruit – the solid residue of the fruit is used as fertilizer in the fields behind the market; The liquid extracted from the fruit flows into two buried containers to produce biogas, which is then used to generate electricity.

Fruit can actually generate electricity? The power generation efficiency of different fruits is not the same.

The copper and zinc sheets form a closed loop through an electrolyte (fruit) and a wire, and the more active zinc sheets can displace the hydrogen ions of the acidic substances in the fruit, forming a battery-like structure that can generate an electric current.

The principle of fruit power generation is similar to that of the earliest chemical batteries。Italian physicist Volt.

The battery was invented. He inserted copper and zinc sheets as two electrodes into a dilute sulfuric acid solution to make a primitive chemical chain jujube battery. In this battery, one electrode is a copper sheet and the other electrode is a zinc sheet, electrolyte.

It is dilute sulfuric acid. Zinc easily loses electrons and oxidizes into zinc ions into solution. Electrons flow from zinc to copper through wires. The hydrogen ions in the solution are obtained from the copper sheets, and the electrons are reduced to hydrogen atoms.

The hydrogen atoms combine into hydrogen molecules that escape from the copper sheets.

During the whole process, the electron outflow is at the negative electrode, and the oxygen shed is dismantled.

The electron inflow is positive at one pole, and a reduction reaction takes place. Electron transfer occurs in oxidizing and reducing agents.

Between them, the directional movement of electrons produces an electric current. The principle of fruit power generation is that fruits contain a lot of fruit acids, which are a good electrolyte; Second, the two metal sheets inserted into the fruit usually have different electrochemical activities, so the more active metal pieces can replace the acid in the fruit.

In the fruit power generation and ambush reactor experiments, the two metal pieces are identical, and the fruit acid in the fruit is equivalent to dilute sulfuric acid. Experiments have shown that under the same conditions, different fruit batteries.

There are different voltages, and one of the key factors in the formation of fruit batteries is also the acid content in the fruit. In order to generate electricity, there must be a power supply and a master circuit. In order to generate electricity from a citrus fruit circuit, there must be wires, small lamp bulbs, lemon fruit, and two metal elements.

The power supply in the circuit is lemon fruit. In this experiment, the metals are zinc and copper.

To form the circuit, the metal is put into citric acid.

juice. Lemon juice.

A small amount of the two metals is dissolved, and the electrons in the lemon juice react with each other. Negative electrons produce an electric current through a wire. Electronic motion is indicated with electricity.

In a closed circuit, electrons will pass through and return to the power supply without interruption. Here, lemons containing zinc and copper are used as battery power. Battery power is usually made up of two metals in the electrolyte.

This electrolyte is a liquid that transports electrons from one electrode to another. Citrus fruits will be a chemical reaction between metals.

Due to the two opposing charges, the difference in chemical potential produces a voltage. The voltage will drive the electrons from one electrode to another.

Lemons, oranges, and other citrus fruits are good conductors of electricity。They don't generate their own electricity. However, if they are connected in large numbers to form a large circuit, they can generate enough electricity to light up the bulb.

This setup can be compared to a multi-cell battery. Not only citrus fruits, but also potatoes, apples, and any juicy fruits can act as conductors. Citrus fruit circuits can generate electricity and light up a laplight bulb.

LED citrus fruits can provide power because they consume less electricity than regular bulbs. The study found that calculators can also be powered by citrus fruits.

Know. Because some fruits contain certain electrons that are in a free state, they can generate electricity.

Fruits that can generate electricity are rich in electrolytes, and the principle of fruit power generation is similar to that of the earliest chemical batteries.

I think that it may be that in the case of the original Qisaosou battery, the electrons maintain the stability of the system from the loop, so theoretically the current is directly related to the high concentration of fruit acid.

Fruit can answer the beam to generate electricity. Fruit batteries are manufactured based on the principle of fruit power generation. Fruit battery is a kind of battery that uses the chemical substances in the fruit to react with the metal sheet to produce electrical energy, and the production materials are fruit (acidic), wire, and metal sheet.

The principle of power generation of fruit battery is: the electrochemical activity of the two metal sheets is not the same, the more active metal sheet can replace the hydrogen ions of the acidic substances in the fruit, due to the positive charge, the whole system needs to remain stable (or the charge is generated, the charge causes the following results), so in the case of the composition of the galvanic battery, the free electrons from the circuit or take the stability of the system, so theoretically the current is directly related to the concentration of fruit acid, (If it is to be expressed as a functional relationship, then this function is actually related to ionic strength and quantitative relationship, and has a qualitative relationship with ion concentration), in this case, if the length of the loop changes, it will inevitably cause the loop to change, so it will also cause the voltage to change.

Yes. Fruit batteries are manufactured based on the principle of fruit power generation. Fruit battery is a kind of battery that uses the chemical substances in the fruit to react with the metal sheet to produce electric energy, and the material is made of fruit (acidic), wire, and metal sheet. <

Fruit generates electricity. Through the principle of fruit power generation, the sail wheel fruit battery was manufactured. Fruit battery is a kind of battery that uses the chemical substances in the fruit state Bixin to react with metal sheets to produce electricity, and the materials are fruits (acidic), wires, and metal sheets.

The principle of power generation of fruit batteries is:

The electrochemical activity of the two metal sheets is not the same, the more active metal sheet can replace the hydrogen ions of the acidic substances in the fruit, and the whole system needs to be stable due to the positive charge generated in the stool (or the electric charge is generated, and the charge causes the following results), so in the case of forming a galvanic battery.

The free electrons remain stable from the loop, so that theoretically the magnitude of the current is directly related to the concentration of fruit acids (if it is to be expressed as a function).

Then this function is actually related to the ionic strength and is also a quantitative relationship, and the ion concentration has a qualitative relationship), in this case, if the length of the loop changes, it will inevitably cause the loop to change, so it will also cause the voltage to change.

Fruits can generate electricity because they contain a large amount of electrolytes (i.e., ions with positive and negative charges). For example, apples and bananas are rich in potassium ions, which have a positive charge, and there are also negatively charged ions such as chloride ions.

Ions are charged particles formed by an atom or group of atoms losing or gaining one or a few electrons. Charged atoms are called ions, positively charged atoms are called cations, and negatively charged atoms are called anions. Anions and cations form uncharged compounds due to electrostatic action.

Almost all fruits and vegetables can generate electricity, but the amount of electricity generated is different.

Lemon, watermelon bridge kailu, dragon fruit, power generation is strong. Strawberries, apples, pears, medium power generation. Potatoes, bananas, papayas, power generation Sun noisy is weak.

The juice of fruits and vegetables contains a substance called "electrolyte", which is the precursor to the realization of electricity generation. Fruits and vegetables can generate electricity because fruits and vegetables contain more free water, and some of the minerals contained in them can move freely in an ionic state, and under the attraction of electrodes with different properties, they will move in a directional way and generate current.
