Wind power redefined
At Oneness Power Inc., we are committed to promoting and applying renewable energy technologies. Our current goal is to promote the commercialization of US Patent 11,493,022 B2 — the Linearly Moving Wind Turbine (LMWT), which will provide renewable electricity in a more efficient, economical, and secure manner.
Wind Turbines Today
The best modern solutions to harness wind energy are still challenged in many ways:
- Typically, the blades do not operate within a range of optimal attack angle , resulting in low actual wind energy utilization efficiency;
- High blade tip operating speed produces annoying noises to nearby communities and threatens passing wildlife
- Increasing a single turbine’s sweeping area becomes more and more difficult
The secret is linear
because only Moving Linearly
makes holding a constant attack angle possible
When the wind blade moves in a straight line perpendicular to the wind direction, its actual attack angle α₁ = α₀- β where α₀ is the angle between the blade and the initial wind direction, and β is the angle between the resultant wind speed acting on the blade and the initial wind direction.
The most important thing :
when a blade moves linearly, if α₀ and β remain unchanged, then the actual attack angle α₁ also remains constant.
If we define the force driving the wind blade forward as Fg, then Fg= Fl*cos(β)- Fd*sin(β)
If we define the force that does not contribute to the forward motion of the wind blade as Fb, then Fb= Fl *sin(β)+ Fd*cos (β)
When Vt/Vw=50%，then β =26.57°，If we control α₀< 38.5° and ignore the influence of Fd, it can be concluded that throughout the entire linear motion process, Fg is approximately equal to 0.89 Fl, while Fb is approximately equal to 0.45 Fl.
If we manage to make the wind blade move linearly along the direction of lift force, then throughout the entire linear motion process, Fg = Fl and Fb= Fd.
This means that if we control the attack angle within the ideal range (α₁ around 12⁰), then we can achieve the maximum Cl while keeping Cd close to zero, thereby simultaneously maximizing Fg and minimizing Fb.
LMWT is comprised of groups of carts, moving horizontally along the loop provided by a rotatable guide frame that sits on the chassis. Two gear groups on the frame convert the linear movement of the carts into rotational movement of two vertical axes and transfer the rotation kinetic energy down to a generator house under the frame or on the ground to generate electricity.

Guide Frame & Chassis
How it works
The rotatable guide frame is a multi-layered, stacked,stable hollow structure. Its closed-loop internal cavity consists of two straight sections and two turning sections. In the upwind straight section, the lift (horizontal thrust) generated by vertically arranged blades propels the cart in a linear horizontal motion. As the cart pass through the gears on both outer sides of the guide frame, the straight teeth on both sides of the cart drive the gears to rotate. This allows the vertical shafts of the gears to convert the horizontal linear motion of the cart into vertical rotational motion. The tightly arranged cart sequentially push the gears to rotate, ultimately driving the generators connected to the lower ends of the vertical shafts to continuously produce electricity.
After passing through the gears, the cart first enter the first 180-degree turning section. Here, the lift (horizontal thrust) generated by the blades assists the cart in traversing the remaining downwind straight section and the second 180-degree turning section, ultimately returning to the upwind straight section to complete a cycle. In the downwind straight section and the second turning section, the blades are disengaged from their fixed connection with the cart to prevent the blades from generating negative force. After the cart returns to the upwind straight section, the guide rails at the top of the frame rotate the blade back to their designed position and re-establish a fixed connection with the car. This ensures that the blade always maintain an ideal attack angle in the working zone of the upwind straight section.
The system also includes other auxiliary functions, such as assisting the carts in returning to the working section, enabling the engagement and disengagement of the carts, securing, releasing, and rotating the blades, as well as ensuring safe operation.
