How to generate electricity

Human thermal energy generates electricity by absorbing human thermal energy and converting it into electrical energy. Researchers have invented a band-aid MP3 player, which can generate electricity by using the heat emitted during exercise.

Noise generates electricity, and French researchers have developed a T-shirt that can be charged by noise. A white piezoelectric film is installed on the abdomen of the rechargeable T-shirt. It uses piezoelectric effect to generate electricity. Piezoelectric film converts vibration energy into electric energy.

Walking to generate electricity, develop a kind of generator installed in shoes, which can let those girls who love beauty generate electricity while walking. As long as you take every step, the small generator installed on the heel will be activated to generate weak electricity.

Green algae power generation, Dutch designers designed a green algae lamp, which can convert the energy of algae into electricity. The top of this green algae lamp is filled with half a bottle of water, which is full of green algae. There is also an invisible battery in the water, which can continuously store the weak electricity generated by photosynthesis of green algae.

Weightlifting power generation, gravity light, is the electric light that can provide electricity by gravity. The core component of this electric lamp is a miniature generator, which is pulled by a heavy object.

Leftovers generate electricity and turn kitchen waste into methane. The main part of the kitchen waste power plant is a huge fermentation tank, just like a huge cow's stomach, where kitchen waste is digested and then combustible methane gas is released. Methane gas has a high calorific value and can be directly used for combustion and power generation.

Big trees generate electricity. When the wind blows, the branches and leaves of trees will flutter with the wind, and the kinetic energy of the branches and leaves can be used to generate electricity. The PH value of the root of a big tree is different from that of the nearby soil, and it can also generate electricity.

First, let's briefly understand the principle of power generation. 183 1 year, British scientists discovered the phenomenon of electromagnetic induction, and since then, mankind has gradually entered the era of power generation. The principle of using magnetic field to generate electricity is simple: when the conductor is in a changing magnetic field, charged particles (electrons, ions, etc. ) will move directionally with the changing magnetic field, thus generating current, and the energy that causes the magnetic field to change will be converted into electrical energy.

Until today, most of the electricity used by human beings is still obtained by using this basic principle (water, fire, wind and nuclear power plants convert kinetic energy into electric energy, and there are other ways to generate electricity through solar energy and chemical batteries, but the proportion is relatively low. )

Another thing that needs to be introduced is the SSG system in Beddini. Famous inventors have invented many efficient energy systems. Among them, his Ssg system is the most talked about. This system was designed by Beddini for a friend's daughter's science exhibition project. It is driven by a motor and can generate electricity. There are many variants of this design, and its biggest advantage is that it can realize the mutual conversion between kinetic energy and electric energy efficiently. In addition, it is worth mentioning that although SSG system is still a patent of Beddini, he allows anyone to build the system, so it is unnecessary to build SSG system.

Step 1: Required materials

16× 1 inch aluminum bicycle wheel frame (tires are not needed, the specific dimensions can be changed, spokes or no spokes, the lighter the better, but the edges cannot be magnetic) 12 ceramic ferrite magnet, at least C8 standard.

0.5 inch wide rubber bicycle wheel pad with diameter of 14 or 15 inch.

Triode, 2N3055 will do, others will do, just pay attention to the voltage.

Potentiometer, whose resistance varies from1Ω to 5kΩ, is used to adjust the speed of the wheel (because this is an experiment, you only need to use the motor to turn the wheel, and you need to consider other methods at the end of the day).

2 diodes: each 1N400 1 and 1N4007 1.

470 ω resistance

NE-2 high-voltage miniature neon lamp

3×6 inch solderable circuit board with hole

Coil: The coil in the old-fashioned speaker used here.

Treaty 300 feet enamelled copper wire

Other electrical appliances, fixtures and wooden bases.

Step 2: Make wheels. Wheels are the only moving components on Bedini devices. We need to install magnets on the wheels. First, determine the direction of the north pole and the south pole of the magnet, and then stick the 12 magnet on the wheel at equal distance. After bonding, fix it with adhesive tape to prevent the magnet from sliding during rotation.

Step 3: make a fixed base. This is a woodworking job. In principle, it can be made of other materials as long as it can be used.

Step 4: Make and install the double-wire coil. Two-wire coil means two coaxial coils, which is one of the key parts of Bedini device, so that the whole coil can achieve two functions at the same time: one coil uses the changing magnetic field to generate electromagnetic pulse to drive the wheel, and the other coil generates current to charge the battery. The usual design is to use two turns with a difference of four times in diameter and width. Here, the configurations of 20 turns and 24 turns are used. Then lead out a port of each of these two pipelines, preferably from the bottom. After simple fixing, start winding: wind two wires in the same direction like a thread, and make sure to keep pressing and not loosening. When finished, lead out the other two ports, fix them and press the coil with insulating tape.

The next step is to make the magnetic core. It is better to choose the broken nonferrous metal material as the material of the magnetic core, because the magnetic core needs constant magnetization, which can make this process easier. Besides, pure iron is also very good. What is used here is a magnetic core made of sliced iron sheets. After inserting the magnetic core, press it as tightly as possible and fix it with glue.

Step 5: Install mechanical parts. The installation method is very simple. Align the edge of the runner with the NE-2 neon lamp used in the magnetic core for demonstration. When it is finished, you can replace it with a battery to store the power transistor for voltage amplification.

The driving part of the wheel has been completed. In this system, we can see that electric energy is converted into kinetic energy, and kinetic energy is converted into electric energy, and the final result is that runners are getting faster and faster.

If the system is completely used as a power generation system, the method adopted is very simple: the induction coil is mainly installed at the position corresponding to the permanent magnet.

Finally, the dissatisfied author made a bigger Bedini device with the same basic structure but more magnets.
