Abstract: A wind turbine captures energy from a flowing fluid medium using drum-shaped drive elements that spin while traveling along a continuous orbiting course around a base. Attached roller bearings engaging stationary raceways can guide the drive elements. Means for spinning the drive elements can include toothed belts engaging drive element cog wheels. Spinning can provide Magnus effect enhancement. Wind energy is captured by the drive element motion, then transferred to the base cog wheels by a toothed belt and finally fed to an output shaft. The invention includes locating drive elements in a moving fluid medium, spinning the drive elements as they are urged by the wind along a continuous orbiting course and capturing energy by linking the motion of the drive elements to an external device. The method includes adjusting the base's azimuth and the angle of incidence of the wind in response to wind direction and speed.

Abstract: The invention herein described consists of a system destined to harness wind resources, transferring wind power to the ground station group on the surface, the process being performed through the tensioning and unwinding of the cable group connecting the airborne group to a reeler in the said ground station group. Through the control group the resultant force vector of the aerodynamic forces tensioning the cable can be significantly altered. This change in aerodynamic forces can be done in order to create two different phases which define the cyclic movement performed by the system: a work phase, where the resultant force vector is of greater magnitude and tensions the cable, unwinding it at the ground station group and thus producing power; and a recovery phase (which requires power from the system) when the cable is rewound in order to bring the airborne group back to its original position. Because the work produced in the work phase is of greater magnitude than the work required during the recovery phase, the system generates positive net power, which can then be introduced in the electrical grid, or stored as any other form of energy such as chemical or mechanical.

Abstract: Roughness is added to the surface of a bluff body in a relative motion with respect to a fluid. The amount, size, and distribution of roughness on the body surface is controlled passively or actively to modify the flow around the body and subsequently the Vortex Induced Forces and Motion (VIFM). The added roughness, when designed and implemented appropriately, affects in a predetermined way the boundary layer, the separation of the boundary layer, the level of turbulence, the wake, the drag and lift forces, and consequently the Vortex Induced Motion (VIM), and the fluid-structure interaction. The goal of surface roughness control is to increase Vortex Induced Forces and Motion. Enhancement is needed in such applications as harnessing of clean and renewable energy from ocean/river currents using the ocean energy converter VIVACE (Vortex Induced Vibration for Aquatic Clean Energy).

Abstract: Power generation apparatus includes a wing-shaped blade having opposite sides, opposite ends and leading and trailing edges extending between those ends. A lift differential producing device in the blade produces a lift differential at the opposite sides of the blade and that device is switched so that one blade side or the other produces the greater lift. A blade shaft extends along an axis in the blade that is in close parallel relation to the leading edge of the blade and that shaft is fixed to move with the blade. Supports support the blade shaft so that the blade can be positioned in a fluid stream with the leading edge facing upstream and swing about the axis between first and second extreme positions on opposite sides of a neutral position, the blade shaft oscillating with the blade. A coordinating device coordinates the switching of the lift differential producing device with the swinging of the blade so that the switching occurs at the extreme positions of the blade. A method of generating power using the apparatus is also disclosed.

Abstract: A Flettner rotor that employs localized suction over its surface improves performance and fuel efficiency. Simulations and analysis show that such a method can significantly improve the performance of the Flettner rotor. Improvements in rotor performance enable reduction in fuel costs and greenhouse gas emission by ships or other modes of transport. Improvements in rotor performance can also reduce noise for applications such as drones or other devices having rotors.
