Use redstone dust as wire.
In Minecraft, wind turbines use redstone dust as wires to transmit energy. Redstone dust is a red powdery item that can be used to activate redstone circuits and transfer energy. When the wind turbine generates electricity, it transmits the energy to connected devices through redstone powder, activating or driving the devices.
Principles of wind power generation and solar power generation
There are many forms of motors, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic power and achieve the purpose of energy conversion. According to the different starting and running modes of motors, they can be divided into capacitor-started single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, split-phase single-phase asynchronous motors, and three-phase motors.
According to the different structure of the rotor, the motor can be divided into cage induction motor, which is the one you are using (the old standard is called squirrel cage asynchronous motor) and wound rotor induction motor (old standard The standard is called a wound-type asynchronous motor). A squirrel cage is a closed coil.
(1) When a three-phase asynchronous motor is connected to a three-phase AC power supply (each phase differs by 120 degrees in electrical angle), the three-phase stator winding flows through the three-phase symmetrical current and generates the three-phase magnetomotive force (stator Rotating magnetomotive force) and generates a rotating magnetic field, which rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed.
(2) The rotating magnetic field and the rotor conductor have relative cutting motion. According to the principle of electromagnetic induction, the rotor conductor (the rotor winding is a closed path) generates an induced electromotive force and an induced current (the direction of the induced electromotive force is determined by the right hand) Then judge).
(3) According to the law of electromagnetic force, under the action of induced electromotive force, an induced current will be generated in the rotor conductor that is basically consistent with the direction of the induced electromotive force. The current-carrying rotor conductor is affected by electromagnetic force in the magnetic field generated by the stator (the direction of the force is determined by the left-hand rule). The electromagnetic force forms an electromagnetic torque on the motor rotor shaft, driving the motor rotor to rotate along the direction of the rotating magnetic field. When the motor When there is a mechanical load on the shaft, mechanical energy is output outward. Since the magnetic flux in the part without the short-circuit ring is ahead of the magnetic flux in the part with the short-circuit ring, the direction of motor rotation is the same as the direction of the rotating magnetic field.

1. Wind turbine
Wind turbines can be divided into DC generators and AC generators.
1. DC generator: A DC generator is mainly composed of a generator shell, a magnetic pole core, a magnetic field coil, an armature and a carbon brush (as shown in Figure 1). Working principle of power generation: When the wind drives the armature of the generator to rotate, due to the residual magnetism in the magnetic pole core of the generator, the armature coil cuts the magnetic lines of force in the magnetic field. According to the principle of electromagnetic induction, the current is generated by the magnetic induction and the current is output through the carbon brush.
2. Alternator: The alternator is mainly made of magnetic materials with multiple permanent magnets (called the rotor) arranged alternately at the north and south poles and an armature coil (called the rotor) made of silicon cast iron and wound with multiple sets of series coils. (for the stator). Working principle of power generation: The rotor is driven by the wind to axially cut the magnetic lines of force. The alternately arranged magnetic poles in the stator form an alternating magnetic field in the coil core. When the rotor rotates once, the direction and size of the magnetic flux change many times. Due to the transformation of the magnetic field, An induced current varying in magnitude and direction will be generated in the coil and delivered by the stator coil. ?
2. Solar power generation
Solar power generation methods There are two ways of solar power generation, one is the light-heat-electricity conversion method, and the other is the light-electricity direct conversion method. . ?
1. The light-heat-electricity conversion method uses the thermal energy generated by solar radiation to generate electricity. Generally, a solar collector converts the absorbed thermal energy into steam as a working fluid, and then drives a steam turbine to generate electricity. At present, it can only be used on a small scale in special occasions, and large-scale utilization is economically uneconomical and cannot compete with ordinary thermal power plants or nuclear power plants. ?
2. Light-to-electricity direct conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for light-to-electricity conversion is the solar cell. Sunlight shines on the p-n junction of the semiconductor, forming new hole-electron pairs. Under the action of the electric field of the p-n junction, holes flow from the n region to the p region, and electrons flow from the p region to the n region. After the circuit is turned on, a current is formed. This is how photovoltaic effect solar cells work. Solar cells are a promising new power source with the three major advantages of permanence, cleanliness and flexibility.
