River turbines do not generate electricity directly from water flow. The kinetic energy of the water flow is transferred to the turbine, and the turbine drives the generator to convert the kinetic energy into electrical energy. The coil is a solid conductor containing a large number of free electrons and the magnetic field is an artificial permanent magnetic field or electromagnetic field.
The river power generation mentioned here must be a method of electricity production that does not use rotating machinery such as hydraulic turbines. This is called fluid power generation.
High-temperature plasma power generation in fluid power generation has been shown to be feasible. The coil is a gas containing a large number of free ions, and the magnetic field is an artificial permanent magnetic field or electromagnetic field or geomagnetic field (principle of genlightning).
Electricity produced by the river should also be feasible.
River water contains a large number of free ions. In the river flowing from east to west, the free ions cut the geomagnetic field, which will generate many current vortices rotating up and down inside. receivers located a certain distance in the river can capture and exploit these eddy currents. Artificial magnetic fields can also be created to make electricity production more efficient. In this way, water from slow-flowing rivers can be fully used to produce electricity.
The principle of the water wheel:
1. The water wheel is over 10 meters high, with 24 wooden spokes supported by a 5 meter long axle 0.5 meter in diameter. . Radially distributed in all directions. The top of each spoke carries a scraper and a bucket of water.
2. The scraper scrapes the water and the water bucket fills the water. The water from the river rushes into it and the rays rotate slowly due to the inertia of the water movement. Each bucket is filled with river water and is lifted step by step. At the top, the water bucket tilts naturally, discharging water into the aqueduct and flowing to the irrigated farmland.

Development stage
1. Waterwheels appeared in official Chinese written records around the Eastern Han Dynasty. At the end of the Eastern Han Dynasty, during the reign of Emperor Ling, Bi Lan was ordered to build a "rolling cart", which already had basic devices such as grooved plates wheel axle.
2. The development of water wheels reached the Tang and Song dynasties. Great progress has been madeized in the application of wheel and axle. They could use hydraulic power as energy and create a “cylindrical wheel”. And the connection tube, it can make high low water sending.
3. In the Yuan and Ming dynasties, the development of wheel axles became more advanced. A waterwheel had not just one set of gears, but up to three sets, and had "water reversal." , “turning of oxen” or “turning of cows”. “The donkey turns the overturning cart” can be used interchangeably depending on the wind and ground.
