Abstract: Improvements in an exercise machine where the fan blades alter the resistance created by the blades or vanes by moving a cone that pushes the blades out from a central position. The blades or vanes push against the cone with springs. The cone is then moved into or out of the central axle to alter the effective diameter of the blades or vanes. A twist or contouring of the blades or vanes can be obtained at the same time to alter the resistance. In another embodiment, the fan blades can be individually or collectively adjusted to change the resistance. As the diameter is increased the speed of the blade tips increases as a squared function of the radius without changing the rotational speed of the vane(s). The shape, angle, scoop or tilt of the blade or vanes can also be altered to change the resistance.

Abstract: Systems, methods, and devices are provided to generate a stable supply of electrical power in a drill string. In one example, a downhole turbine generator includes a turbine, a speed governor, and an alternator. The turbine may transform hydraulic power of a first fluid medium into rotational power of a rotating shaft. The speed governor may reduce the rotational power of the rotating shaft in a variable amount that depends on the speed of the rotating shaft. Specifically, weighted arms may shear a second fluid medium more when the speed is higher and less when the speed is lower. The shearing of the second fluid medium may generate a countervailing torque on the rotating shaft to reduce the rotational power of the rotating shaft. The alternator then may produce a generally stable supply of electrical power from the rotational power of the rotating shaft.

Abstract: Smooth, preferably variable-sweep fluid collection device surfaces disposed into opposition with wind, river, surf, ocean or tidal currents generate enhanced velocity fluid flows at length driven into onboard work-extracting disc turbines at advantageous angles of attack. Keyed to shafts turning freely through optionally extendable volutes, disc turbines comprising a dense population of smooth, axially fixed or adjustably spaced discs conducting preferably laminar flow between adjacent elements develop significant torque through boundary layer adhesion and viscous shear-stress between fluid layers. Exhaust of disc turbine throughput into divergent channels drafting into external currents of initially higher than ambient velocity and lower pressure may reduce turbine discharge backpressure, rapidly clear system throughput, and allow normally disadvantageous drag to be utilized to develop greater work generation.

The super-large scale, integrated, multi-unit rotor blade wind turbine has four sets of wind force collecting rotor blade turbines composed of an auxiliary up-wind rotor turbine and three down-wind rotor turbine units evenly spaced around a central pivotal rotor hub on extenders which arc the same length as the radius of the auxiliary turbine blade.

Abstract: A vertical axis wind turbine of the type having collapsible fabric sails (10) that reside on the rim of a horizontally disposed square rotor wheel (12,14) supported on a pivotally operated vertical mast (30). Four sails (10) are joined in oppositely disposed pairs and communicate by cables (16) through guides (18) that are positioned on a square rotor hub (14) and control the shape of the linked sails. When acted upon by wind, the sails reciprocally open and close to form two shapes. The two shapes are a scoop and a wing. The scoop holds the wind when receding from the wind. The advancing sail forms a wing that rides the wind promoting stability and reducing friction in the rotor wheel. The action of the advancing sail dampens the sail action of the opening sail and limits the opening sail to a preferred scoop shape.

Abstract: A process and system for harvesting energy from wind action on the high seas ill all weather conditions, on a year-round basis. This process depends upon the use of seagoing platforms (FIG. 2+ FIG. 4) which themselves achieve stability in the presence of storms at sea, doing so through the selective extraction of wave energy. The selective wave energy extraction takes place in such a way that the prevailing ratio of sea height to swell height affecting a typical seagoing platform ((FIG. 2 or FIG. 4)) is reduced to a small fraction of the ratio of sea height to swell height which prevails at a distance from the platform. In short, this process and system stabilizes a plurality of seagoing platforms which support wind and wave energy conversion means, while simultaneously extracting and converting energy from the combined wind and wave action.

A power generator produces electrical energy from the rotation of the rotor which revolves due to the combined impingement of the fluid mover (28) and intensified regenerated circular fluid movement created by the artificially created unconfined vortex.

Abstract: A vehicle compressed air energy converter has been developed for use along vehicular roadways, railways and airfield runways to collect wind pressure developed by the vehicles, trains and aircraft moving through the atmosphere and convert such air motion to other useful forms of energy. The converter is activated by the force of the compressed air movement entering the converter and pushing the retractable air fins of the converter in a circular motion. That circular motion is transferred to a central shaft set in bearings at either end of a housing. As the multiplicity of air fins held in place by hinges on a circular rotating base move within the converter housing, the fins move into a retracted posture so as to offer less air resistance as they circulate within the portion of the converter not subject to movement of air from the exterior of the housing.

The invention comprises a big wheel and a little wheel where the little wheel rotates about on axis parallel to but offset from an axis about which the big wheel rotates. The little wheel rotates within the big wheel. Flexible sails are fastened between masts of the big wheel and masts of the little wheel so that when the wheels rotate each sail is unfurled and extended during one phase of operation and said sail is folded upon itself during another phase of operation. When extended or stretched open, the sail derives power from the fluid current. When the sail is folded, it offers a reduced resistance to the fluid current into which said sail is moving.
