Title: Spin-stabilized magnetic levitation without vertical axis of rotation

Abstract

The symmetry properties of a magnetic levitation arrangement are exploited to produce spin-stabilized magnetic levitation without aligning the rotational axis of the rotor with the direction of the force of gravity. The rotation of the rotor stabilizes perturbations directed parallel to the rotational axis.

Propulsion and stabilization system for magnetically levitated vehicles

Patent Coffey, Howard T [Darien, IL]

A propulsion and stabilization system for an inductive repulsion type magnetically levitated vehicle which is propelled and stabilized by a system which includes propulsion windings mounted above and parallel to vehicle-borne suspension magnets. A linear synchronous motor is part of the vehicle guideway and is mounted above and parallel to superconducting magnets attached to the magnetically levitated vehicle.

Rotation-speed-independent stabilizer for passive magnetic bearing systems

Patent Post, Richard F.

By employing a combination of magnetic forces and those from electrostatic fields, a new stabilizer is able, unlike those employing dynamic effects, to function at any speed with no need for sensors or dynamically generated electrical currents. Embodiments are provided that stabilize the radial, axial and tilt instability. In addition to its use for stabilization, the radial stabilizer described herein also functions as an eccentricity detector.

Magnetic levitation configuration incorporating levitation, guidance and linear synchronous motor

Patent Coffey, Howard T [Darien, IL]

A propulsion and suspension system for an inductive repulsion type magnetically levitated vehicle which is propelled and suspended by a system which includes propulsion windings which form a linear synchronous motor and conductive guideways, adjacent to the propulsion windings, where both combine to partially encircling the vehicle-borne superconducting magnets. A three phase power source is used with the linear synchronous motor to produce a traveling magnetic wave which in conjunction with the magnets propel the vehicle. The conductive guideway combines with the superconducting magnets to provide for vehicle leviation.

Aeroelastically coupled blades for vertical axis wind turbines

Patent Paquette, Joshua; Barone, Matthew F.

Various technologies described herein pertain to a vertical axis wind turbine blade configured to rotate about a rotation axis. The vertical axis wind turbine blade includes at least an attachment segment, a rear swept segment, and optionally, a forward swept segment. The attachment segment is contiguous with the forward swept segment, and the forward swept segment is contiguous with the rear swept segment. The attachment segment includes a first portion of a centroid axis, the forward swept segment includes a second portion of the centroid axis, and the rear swept segment includes a third portion of the centroid axis.

Vertical axis wind turbines

Patent Krivcov, Vladimir [Miass, RU]; Krivospitski, Vladimir [Miass, RU]; Maksimov, Vasili [Miass, RU]; ...

A vertical axis wind turbine is described. The wind turbine can include a top ring, a middle ring and a lower ring, wherein a plurality of vertical airfoils are disposed between the rings. For example, three vertical airfoils can be attached between the upper ring and the middle ring. In addition, three more vertical airfoils can be attached between the lower ring and the middle ring. When wind contacts the vertically arranged airfoils the rings begin to spin. By connecting the rings to a center pole which spins an alternator, electricity can be generated from wind.
