After arranging the quarrying to build an artificial waterway, Wei Minsheng pondered how to solve the problem of Wang Wushun and their electricity in Zigui City. In this world where war may occur at any time, the establishment of a power supply network is an unrealistic problem, because the safety of the power grid cannot be guaranteed, it is impossible to send troops to guard each tower, after all, the main body of the tower is steel, this thing is an important strategic material for the other world, and it is unreasonable not to be robbed. If the problem of distributed power supply is not solved, it will inevitably affect its future development.

Solar cells are not easy to install there, the roof is not secure, and if the wind is stronger, large solar panels can lift the roof. Other forms of power generation are either inappropriate or require fuel. Wei Minsheng doesn't want to send these power generation equipment out now, after all, these fuels are also dangerous goods, either flammable, explosive or poisonous, and there will be a big incident without special management.

After thinking about it for a long time, I got some inspiration from the waterwheel, this power generation is nothing more than using a stable force to drive the rotor of the generator to do work, and the coil cuts the magnetic field lines to generate current. Water power can, why can't manpower? By the way, it is a matter of stability, it is impossible for manpower to exert force stably for a long time, especially when there are many people, the size of this force is really difficult to control.

In the real world, there are many unstable but abundant mechanical energy, such as wind energy, tidal energy, etc.

It is estimated that the world's wind energy reserves are as high as 130 billion KW, which is 10 times larger than the total amount of hydropower that can be developed on the earth, but due to the instability of wind energy, it cannot ensure uninterrupted and stable power supply, so only more than 50 million KW has been developed in the world, and due to the problem of power supply network, a large amount of wind power cannot be stored and can only be wasted.

There is also a lot of tidal energy, and it is estimated that the world's tidal energy reserves are also 2.7 billion KW, but its energy performance is reciprocating and uneven. At present, the main utilization of tidal energy is tidal power generation. Tidal power generation is similar to the principle of ordinary hydropower generation, through the reservoir, the seawater is stored in the reservoir at high tide, stored in the form of potential energy, and then, at low tide, the seawater is released, and the difference between high and low tide levels is used to drive the turbine to rotate and drive the generator to generate electricity. The difference is that seawater is different from river water, and the difference between the accumulated seawater is not large, so the utilization rate is not high.

If there is a way to convert this unstable mechanical energy into stable energy storage, these renewable and clean energy will definitely be able to develop rapidly.

When Wei Minsheng was learning programming before, he came into contact with a concept, that is, caching. In the past, when running the DOS operating system with 286 and 386, if you entered a display command with more content after the prompt, such as "dir*.*", and entered other DOS commands immediately after entering, regardless of the screen execution, you will find that the next command will be executed after the previous command is executed. This is the role of the keyboard entry cache, if the system can't handle a large number of consecutive commands, it will cache the following commands, and then execute the commands in the cache sequentially when the system is idle, this situation is similar to the current problem.

So, is there a way to cache the excess power and output it stably? The answer is, of course, yes, the real-world hydropower station is this principle, using excess electricity to pump water to the reservoir, and releasing water to generate electricity when there is a shortage of electricity, which can play the role of staggering peaks and valleys. But this model is something that Wei Minsheng can't do now, so he has to find another way.

Wei Minsheng listed all the methods that can be stored in his impression, including water storage, heat storage, flywheel, and spring...... Hey, it seems that the spring has the effect of energy storage, but the energy that can be stored is not much, and it is still a little worse to push the generator rotor to rotate at high speed, and the service life of the spring is also a problem.

From the perspective of the previous energy storage methods, water storage is the potential energy of converting kinetic energy into water, heat storage is the conversion of kinetic energy into heat energy, and flywheel is the storage of kinetic energy by inertia. Among the above three methods, only the potential energy is stored for the longest time, and both thermal energy and inertia have the problem of energy loss, so we have to make an idea from the potential energy.

Both the cache and the stack have the function of throttling buffering, but the working mode is a little different, the cache is first-in, first-out, with two channels, and the stack is first-in, last-out, with only one channel. In order to maintain the power input while maintaining the power output while maintaining the uninterrupted power output, the only way to choose the first-in, first-out dual-channel operation mode is to choose, otherwise the power output will be interrupted when the force is input. Pumped energy storage is this mode of work, the pumping port and the power generation channel are separated, one in and one out, which also uses the nature of water to flow to a low place, what power does this nature have to do with it? …… Yes, gravity, if you want to use the method of increasing the potential energy of solid matter for energy storage, the continuous work of gravity is a problem that must be considered.

If you use a tall rack, set up a shaft at the top of the rack that can rotate in one direction, and hold a gear in the middle and at each end of the shaft that can only rotate in one direction, and use an extended chain to hang down to the ground. The middle chain is fixed with a gear that meshes with each other, the gearbox and the generator are fixedly connected on the gear, the generator and the gearbox themselves are used to increase the speed of the generator under the effect of the gear teeth and the gearbox, as long as the weight of the counterweight equipment such as the generator is controlled, under the condition of a certain gravity, the potential energy is converted into kinetic energy, and a stable power output can be obtained.

At this time, a stable power output is achieved, but the distance of the generator cannot exceed the height of the shelf, so the input terminal needs to be modified.

Under the one-way gear at both ends, a bicycle pedal gear is connected and fixed, connected with a chain, as long as the pedal is pressed, the chain will drive the one-way shaft to rotate, and under the effect of the intermediate gear rotation, the generator assembly is lifted up by the chain, converted into potential energy and stored, so as to realize the input of power.

After the whole device is installed, such a cycle will be formed: the unstable human input will lift the generator component upward, and the lifted generator assembly will output a stable current under the action of gravity, and the height that the intermediate chain can lift is the potential energy that can be buffered.

If more counterweight materials are used because of the large output power of the generator, such as stones, dirt and other things, it is necessary to increase the number of intermediate load-bearing gears and chains, and more gears and chains should be added at both ends, so as to use more human power to lift the generator components and counterweight materials.

After simulating this set of equipment in my mind several times again, I sorted out a production procurement list of accessories and related parameters that must be purchased or produced by the real world, and after confirming that it was correct, I sent it to Liu Mengling, who arranged personnel to be responsible for procurement and processing.

PS: There is a hidden design idea for a portable charging device, but there is a key point that has not been said, and it can be patented, hehe......
