Enzyme batteries should be easier to make. Use glucose as a reagent. Make an electrolytic cell separated by a proton exchange membrane. Put glucose, glucose oxidase and coenzymes into the anode, then connect it to the cathode. Simply connect the Yin and Yang poles.
Enzyme battery
Enzyme batteries generally use glucose as the reaction raw material. The principle of the reaction is as follows:
Under the action of glucose oxidase (GOx) and coenzymes, glucose loses electrons and is oxidized to gluconic acid. The electrons are transported to the anode by the mediator then to the gluconic acid. cathode through the external circuit. Hydrogen peroxide gains electrons and is reduced to water by the action of oxidase.
Anodic reaction: glucose→gluconic acid+2H++2e-
Cathodic reaction: H2O2+2H++2e-→2H2O

The microbial battery consists of an anode chamber and a cathode chamber. A proton exchange membrane separates the two polar chambers. The basic reaction type is divided into four stages:
1) Under the action of microorganisms, the fuel undergoes an oxidation reaction and electrons are released at the same time.
2) The mediator captures the electrons and transports them to the anode.
3) Electrons reach the cathode through the external circuit and protons enter the cathode chamber from the anodic chamber through the proton exchange membrane.
4) Oxygen receives electrons at the anode and a redox reaction occurs.
Anodic reaction: C6H12O6+6H2O→6CO2+24H++24e
Cathodic reaction: 6O2+24H++24e-→12H2O
When the biobattery is It works by converting the chemical energy of the fuel into a form that allows electrochemical reactions to be easily carried out. It existste two methods:
The first involves using an enzyme to oxidize the fuel, and the resulting enzymatic reaction product is then subjected to an electrode reaction (a system in which the energy transfer system electrons is not paired)
The other is An enzyme containing a coenzyme is used to oxidize the fuel, and the coenzyme that is combined and reduced during the oxidation of the fuel is oxidized on the electrode (system coupled to an electron transfer system).
Commonly used enzyme batteries using glucose as fuel are manufactured by mimicking the reaction mechanism of mitochondria and are ideal models for enzyme batteries using glucose as fuel.
The cost is a bit annoying and the technology is difficult. It is recommended to buy solar panels + batteries + inverters to do so.
You can only generate photother poweronly by yourself. Paint an aluminum plate black, press the thermoelectric power generating part below and below the thermoelectric power. The generating part is an aluminum plate, and dip the aluminum plate underneath into water. But the electricity produced is pitiful.
2. Use hot water from solar water heater + thermoelectric film: make a heat exchanger, use hot water to heat the upper plate, and use cold water to cool the lower plate if there is a temperature. difference on both sides of the thermoelectric film, electricity will be generated.
3. Use heat pipes + thermometers
4. Heat pipes + working fluid Freon + thermal engine + generator (the configuration of a solar power plant cannot be carried out by individuals)
