This wind turbine does not have a rotating shaft. Only the blades rotate around the shaft. The power generation unit is also attached to the shaft and generates electricity in response to the rotation of the blades. Since the shaft is simply secured to the frame at the top and bottom, there is no need to consider the alignment of the rotating shaft. If the frame is sturdy, it can withstand strong winds. There is a proven record of withstanding wind speeds of up to 30 m/s in field tests.

The "floating cross-axis wind turbine" supports the rotation axis of the wind turbine with dual bearings, allowing it to always receive wind from the same direction, making it possible to reinforce the supporting structure. Since the rotation axis of the wind turbine intersects with the wind direction, the rotor's attitude towards the wind does not change even if the floating body sways. When a gravity-operated opening and closing panel is attached to the blades, the panel opens when the rotor's rotational speed is low, increasing the wind-catching area (drag-type wing). Conversely, when the rotational speed is high, the panel closes due to centrifugal force and other factors (lift-type wing). 【Features】 ■ The rotation axis of the wind turbine intersects with the wind direction ■ The orientation of the wind turbine naturally aligns with the wind direction ■ The structural strength of the wind turbine support can be enhanced ■ Opening and closing panels can be attached to the blades *For more details, please refer to the PDF document or feel free to contact us.

Our company is developing a "non-powered yacht-type drone" that can maintain the same water area offshore without being fixed to the seabed. This utilizes the principle that a sailing vessel can move in the windward direction due to the effect of the keel underwater. By shaping the hull symmetrically and reversing the sail against the windward direction, it moves back and forth laterally in relation to the windward, similar to a train's switchback. 【Features】 ■ Maintains the same water area offshore without being fixed to the seabed ■ Moves using the wind force acting on the sail, eliminating the need for other power sources ■ Equipped with wind turbines and other devices to generate electricity, allowing various equipment to be used *For more details, please download the PDF or feel free to contact us.
