Abstract

[Problem] To provide a cascaded hydroelectric power generation device. [Solution] An inclined tunnel is constructed in the mountains. A number of water channels and turbines are installed in multiple stages inside the constructed tunnel. The water channel is made into an egg-shaped hose, with the upper half covered or open, and the water wheel is spherical. In order to make an easily removable generator, the cascaded hydroelectric generator is modified to a spherical shape, the number of blades is increased to about 12, and a paddle-shaped water return is provided and molded integrally with the water wheel. Furthermore, angles and wrinkles are molded to make it easier to catch running water. [Selected drawing] Figure 5

1. Propose new natural energy to Japan, a country with no natural resources.
2. Provide the world with natural energy and stop global warming.
3. A warning against the Japanese sense of peace and economy (indirect complicity in war) of buying oil with dollars and recouping the dollars by exporting arms to the Middle East to the United States.
4. Contribute to a carbon-free society.
5. China has set a goal of zero carbon dioxide emissions, and electricity prices in China are 10 yen/kW, compared to 12-14 yen in Japan. With hydrogen power generation, electricity prices are expected to be 100 yen/kW. There are fears that the low prices in China will cause a decline in Japan's industry and economy. To address this issue.
(China can achieve zero carbon dioxide emissions by increasing nuclear power plants that are free from earthquake risks and offsetting them with desert greening.)

1. Build many cascaded hydroelectric power plants that incorporate existing technologies.
2. This method will reduce the import and use of oil for combustion.
3. If the electric power companies are unable to handle the situation, local governments should utilize funds to promote local production and consumption of energy, establish local electric power companies, create local jobs, and reform and revitalize Japan's industrial structure.
(The same as the previously applied-for patent "Power Generation System Combining Japanese Technology")

1. Although construction costs will be high, since there are no fuel costs, by adjusting energy costs it will be possible to achieve industrial restructuring that will enable the country to compete with the rest of the world in terms of low labor costs.
It will also fundamentally stabilize Japan's economic structure and contribute to moving away from oil and nuclear power.
2. Japan's oil imports and expenditures will decrease, reducing the need for American dollars to be collected and making it more able to contribute to world peace.
3. If electrical energy can be supplied to European Russia, Japan-Russia negotiations can be returned to the origins of the 1855 Japan-Russia Treaty of Amity, we can demand southern Sakhalin from Japan, build a Shinkansen line via Sakhalin across Russia from east to west, and establish a power distribution network, making it possible for millions of democratized Russians other than Putin to work and travel to Japan (this would be a true Japan-Russia peace treaty).

Bird's-eye view of the mountain: An imaginary image of the exterior as seen from the mountain. Water usage and downstream facilities (eliminating the pollution and shortcomings of dam-type hydroelectric power generation) Elevation: Cross-section of the tunnel (internal structure and equipment layout). There are six waterways on either side, and 12 turbines. Turbine cross section: We proposed a spherical waterwheel structure with the power generating section and blades connected. When we think of waterwheels, we imagine wooden, vertical waterwheels found in the countryside, but the rotation speed of the shaft is crucial for the generator to function properly. The tip of the coil inside the generator: 60 cm wide, with the capacity to generate electricity for more than 240 bicycles. Existing nuclear, thermal and wind power plants generate electricity from rotation caused by friction. This proposal generates electricity from sparks caused by metal contact, which is a precision machine that is difficult to manufacture. External view of the cascaded water/wind power generator: This is a small generator that features a handle and a suspension section, allowing maintenance to be done manually.

(1) Developed as a local industry by local governments and local banks.
(2) It needs to be constructed as a nationally planned project involving light industrial companies, the civil engineering and construction industry, and ten electric power companies.

1. Provide electric energy throughout Japan.
2. Shift away from oil and nuclear energy sources to energy production and become self-sufficient.
3. All-electric (non-polluting) Japanese industries, primarily the automobile industry.

Claims (9)

[Constructing a tunnel at an angle between mountains]
The hydroelectric power generation of the proposed "cascaded water and wind power generation system" cannot be achieved unless the water flows at a high angle like a slide. Therefore, the tunnel excavation and its angle should be 5 to 10 degrees or more, and depending on the special terrain, it may be necessary to excavate at a considerable angle.
(Similar to the previously patented "cascaded hydroelectric power generation system") [Multiple water channels and turbines installed in the tunnel]
This involves creating multiple water channels (hose-like pipes) inside the tunnel and installing a large number of water turbines that act as power generators.
The water wheels will be spaced approximately 1 meter apart in 12 rows, and will be laid out in an almost straight line over a distance of several tens of meters to several tens of kilometers.
(12 times the capacity of the "Japanese technology power generation system" for which a patent application was filed earlier.) [The waterway is made into an egg-shaped hose, with the upper half covered or open]
With maintenance in mind, windows and spaces will be provided to make it easy to remove, install, and replace the waterwheel.
(Making it compatible with wind power generation in addition to hydro power generation) [The water wheel is a spherical type generator that can be easily removed.]
The water wheel is made spherical to fit the shape of the hose-like tube used as the waterway, and is simply placed in the center of the waterway. A generating coil is placed in the center of the water wheel, separating the positive and negative poles. By using bearings, it is possible to kill two birds with one stone by rotating with less resistance. The width of the water wheel sphere is about 0.6 meters even with the blades attached, and it is made of reinforced plastic, aiming for a lightweight of 10 to 20 kg.
(By making the waterway egg-shaped, space is secured between the round shapes.) [Abdut monorail for maintenance work in tunnel]
In the center of the tunnel, an abduct-type track and a trolley-type train that can be equipped with a ladder or crane will be installed to allow for maintenance such as generator replacement.
In addition, it will be possible to use trolley-type passenger cars as well. [Adding a pumped storage system to cascaded hydroelectric power generation]
Water tanks and purification facilities will be installed at the top of the mountain and in the city below, and pumped-storage power generation will be provided. The basic idea is to ensure a stable water flow in addition to the natural flow of the river, and the upper part will be connected to a dam, which will also have the function of replenishing the water in the unlikely event that it dries up.
(The same as the previously patented "cascaded hydroelectric power generation system") [Compatibility between hose pipes used as water channels and wind ducts for wind power generation]
The cascaded hydroelectric power generation and the cascaded wind power generation use a common hose-shaped pipe, which makes the manufacturing process easier and reduces costs.
(The upper half of the water pipe inside the tunnel is open, and the water and air pipes outside the tunnel will have solar panel covers attached, so the hose pipes are almost the same.) [Connecting a blower inside a hose-like tube for cascaded wind power generation]
The hose-like pipes, which stretch for tens of kilometers, are like water pipes, and they need to be air ducts, or in other words, air blowers, which are connected every 1 km or so.
(The blades of a windmill are turned by a strong wind that is artificially created in the same way as a water current.) [Add water return and water receiving angle blades to the waterwheel blades]
The cascaded hydroelectric generator was modified into a spherical shape, and the number of blades was increased to about 12, with webbed water return blades, similar to the feet of a frog or duck, being integrated into the waterwheel and molded.
In addition, the angle and wrinkles are molded to make it easier to catch running water.
(The generator is made of reinforced plastic to make it lightweight and easy to mass-produce.)
