A horizontal axis rotational force generator is introduced, utilizing fluid flow to drive motion. The system includes one or more rotating mechanisms, each with multiple blades positioned at equal phase angle intervals. These blades revolve around a horizontal shaft while simultaneously rotating around parallel sub-shafts when exposed to fluid pressure, producing torque on the main shaft. A support structure holds the shaft and allows stable axial rotation at designated heights. A gear interlocking unit adjusts angular velocities, shifting blade revolution speeds to half their value in the opposite direction, and transfers the result to the main shaft. As blades pass vertically above the shaft, their orientation is controlled so that surfaces align horizontally or vertically relative to the shaft. This ensures blades consistently generate maximum rotational force on the horizontal plane, efficiently converting fluid flow into usable mechanical energy.

The images shown in "Image Diagram," "Image Diagram 1 Showing Changed State," and "Image Diagram 2 Showing Changed State" are images for displaying weather forecasts and information. These images, such as those in "Reference Diagram 1 Showing Usage State," "Reference Diagram 2 Showing Usage State," and "Reference Diagram 3 Showing Usage State," are used to display information such as the weather forecast for the location shown on the map. Specifically, as shown in "Reference Diagram 1 Showing Names of Each Part," "Reference Diagram 2 Showing Names of Each Part," and "Reference Diagram 3 Showing Names of Each Part," these images consist of weather information display area A and weather information display area B. Weather information display area A displays a map of the location specified by the pointer and its surroundings, and the amount (depth) of snow on the map is indicated by color. Weather information display area B contains a graph area and a play / stop button. The graph area of ​​the "Image Diagram" contains a snow depth bar that displays the presence or absence of snow in a chronological order at the location specified by the pointer. When weather information display area B shown in the "Image" is slid (swiped) downward, weather information display area A expands toward weather information display area B, narrowing weather information display area B. This narrows the graph area and the snow depth bar disappears (Image 1 showing the changed state, Reference Figure 2 showing the usage state). Also, when weather information display area B shown in the "Image" is slid (swiped) upward, weather information display area B expands toward weather information display area A. This expands the graph area of ​​weather information display area B, and instead of the snow depth bar, an area graph showing the snow depth at the location indicated by the pointer over time is displayed, along with a depth bar, which serves as the vertical axis of the area graph, and a time bar (Image 2 showing the changed state, Reference Figure 3 showing the usage state). The line on the area graph indicates the snow depth at the location indicated by the pointer. The area area between the line and the horizontal axis of the area graph is colored a specific color. The depth bar is the same color as the weather information display area A, which indicates the depth of snow. The time bar indicates the present, with the right side of the time bar representing the future and the left side of the time bar representing the past. Operating (tapping) the play / stop button causes time to pass, and the area graph moves from right to left as time passes. Operating the play / stop button again stops the display. This allows the user to visually grasp the depth of snow.
