After breakfast the next day, Wei Minsheng, Steward Wang, and Wang Wugui sent Li Yan out of the valley. When he came, he was arrogant, and when he went, he had no momentum, Li Yan and the unit didn't accomplish anything this time, and returned to Zigui City with his soldiers and horses dejected.

Wei Minsheng asked Steward Wang about the road construction outside, and saw that the migrant workers who worked had no place to stay, and the number of their mobile houses was still too small, and even the students were not enough to buy some later. When I returned to the warehouse, I received a message on my mobile phone that the bandsaw machine I had ordered was about to arrive, and I was ready to receive it. Wei Minsheng called back, determined the exact address of the receipt again, and then called Li Wei and asked him to arrange for some people to prepare to receive a bandsaw machine. After preparing these, Wei Minsheng suddenly thought, yes, I used to be ready to decompose trees with a larger diameter by myself, the equipment was placed in the real world, of course there is no problem with the power supply in the real world, the problem is that now the band saw machine has to be installed in the other world, this electric tiger, 15 KW, how can there be such a large power supply capacity over there.

It's okay, it's good that we have Baidu. Wei Minsheng checked some relevant information on the Internet, and it is unrealistic to build dams for hydroelectric power generation; Although gasoline and diesel generators are simple, this oil is too specific; Wind power generation, such a high-power wind turbine itself really does not have the ability to lift, and the power directly generated is not stable, and there is not such a large inverter equipment when stored with batteries; The equipment needed for thermal power generation is big at first glance, and it is too unrealistic to go to find coal by yourself; There is also the problem of solar power generation without suitable inverter equipment; Tidal power? Geothermal power generation? Nuclear power? Nima, these are even more unreliable.

Let's take a look at the almighty Taobao, at least the things on Taobao are closer to reality. After searching for generator sets, the main product fuels are still gasoline and diesel, wind power, solar power, and so on...... Biogas generator set, this is good, it's a big deal to build more biogas digesters.

Wei Minsheng took a closer look at the relevant information of this product, it turned out that this thing should be called a gas generator set, which can burn gas, straw gas, and biogas, with a rated rate of 60 KW, three-phase output, and a rated voltage of 400V, which is enough for 4 bandsaw machines to work, and the price is not expensive, even the freight is only 80,000 yuan. There is no gas, biogas can be developed, but what Wei Minsheng values most is straw gas. To put it bluntly, carbon monoxide is obtained by gasifying straw or other wood through insufficient combustion. In the past, there was a very hot gasifier that used this principle, but there was no convenience for electricity and natural gas, and the pipeline was easy to be blocked by wood tar for a long time, and carbon monoxide was colorless and odorless, which was easy to cause poisoning, so it gradually lost the market.

Although this kind of gasifier is no longer suitable in the real world, there is no problem in using it to generate electricity in the other world, just place the gasifier and generator set in an open place, and train one or two villagers to be responsible for the operation of the equipment. As for the fuel for the gasifier, don't you see it? Dead grass and fallen leaves all over the mountains, branches and leaves left behind by logging, sawdust and leftovers from processing wood. There are also those tree stumps, directly post work tasks, ask someone to dig them out, and one stump is two yuan Huaxia coins. The dug pit was planted with walnut trees or other fruit trees, and after a few years it was a new source of income.

So Wei Minsheng contacted Liu Mengling and asked them to immediately go to the nearest city's gas generator set sales point to buy one, and at the same time buy one or two dozen sets of gasifiers and related accessories, as well as a few soft gas storage bags and supporting facilities for biogas digesters. As for the connecting pipes of the gasifier, all the PVC water pipes on the market are directly used, so you can buy them locally.

With these things, the energy crisis in the other world can be temporarily overcome, and although there is no permanent solution, there should be no big problem for at least a year.

Thinking of the Lotte Creek next to his villa, there is a hydropower station built in his world, so the water flow should be not small. But now Wei Minsheng has no plans to build a power station, because such a project is too huge, and he can't find so many technicians in the other world to participate in the construction. At my own level, if I came to be a supervisor, I would not be able to repair the dam halfway through the dam and it would be washed away, and the quality could not be guaranteed.

Although the power station cannot be repaired, Wei Minsheng still wants to think of some ways from this Lotte Creek, and for energy, the more the merrier. If the dam can't be built, it won't be able to provide enough water pressure difference, and it is impossible to use hydroelectric generators, but Wei Minsheng thought of a waterwheel and used the power of the waterwheel to drive the generator rotor to generate electricity. The waterwheel can be made of wood, and when your own band saw machine is in place, plus the woodworking table saw machine that I bought before, using the bearings, gears, transmission belts and various connectors in the real society, there is still no major obstacle to the production of the waterwheel.

Since the dam has not been built, there is still a problem that needs to be solved, and that is how to obtain a steady flow of water. For natural rivers, the size of the water flow is closely related to the weather, and the water level also varies. If it is not regulated, it is not known where the waterwheel will be washed away in the event of a flash flood.

For this problem, Wei Minsheng got some inspiration from the Dujiangyan water conservancy project and decided to make good use of the advantages of the terrain. From the point of view of the river bay, the most serious place of water erosion is the outer edge of the bend, while the water potential of the inner bend is weaker, especially on the back water surface, and the river beach is relatively flat, which is caused by the slower current. Therefore, Wei Minsheng decided to build several separate waterways on these sections of the river, and the entrance of the waterway was controlled by the lifting of the sluice gate, and then multiple waterwheels were placed in this separate channel, and the generator rotors were driven by belts and gears to generate a stable current.

In order to reduce the impulse of the river, the frontal surface of the artificial waterway is made in an arc, and the water flows into the waterway through the sluice gates from the side.

In order to make full use of the power of the water flow when the amount of water is low, Wei Minsheng started on the right side of the entrance of the sluice gate and built a dam diagonally upstream. THE DAM IS ONLY 60 CM HIGH, AND WHEN THE WATER DEPTH IS LESS THAN 60 CM, IT CAN ONLY BE DRIVEN DOWNSTREAM BY THE ARTIFICIAL CHANNEL ALONG THE DAM. WHEN THE WATER FLOW DEPTH IS HIGHER THAN 60CM, THE EXCESS WATER FLOWS DOWNSTREAM OVER THE DAM TO AVOID THE EXCESSIVE FLOW OF WATER IN THE ARTIFICIAL WATERWAY AND THE IMPACT ON THE WATERWHEEL.

The materials used to construct the river can be quarried from the nearby mountains for stone repair, or it can be poured directly from concrete. But Wei Minsheng calculated in his heart, the cost of repairing with stone is lower, mainly because the labor cost is low in the other world, two or three catties of rice a day is enough, so as not to pour cement, and there is a lot less trouble.
