The diagram presents the production of home electricity that is may applied in the future to provide the house with the enough energy, so do not need to buy it anymore. Overall, it is evident that the process began with a large tank made from steel, placed under the ground, and will be filled about 75 percent with compost of leaves, food, scraps, and other things, then with water.
Firstly, while this compost ferments methane gas, there are many pipes placed in this tank to allow the gas to get out throw them, then this methane gas enter a storage tank outside the ground, in order to be collected there, which connected with a compressor.
Once the gas compressed in the compressor, it is go through the pipes to a combustion engine, the role for this engine is to get out the mechanical energy. After that, the generator take place to convert the mechanical energy into electrical energy, which can finally use.
The outcome from these processes, which is the electricity, will be stored in the battery, so this battery can provide the home with the energy need in any time.
