Abstract: An accelerator for a windmill structure as described which is a frustro-conical funnel-like device intended to direct a stream of wind therethrough onto the impeller of a windmill. As the wind passes through the device, it is constricted whereby the velocity increases and exits a throat-like outlet as a diverging jet impacting the impeller blades to thereby increase the kinetic energy available to be converted to mechanical or electrical energy by said windmill. The device of this invention can include a vane for maintaining the accelerator facing into the wind with the windmill, a mounting platform for either the accelerator or both accelerator and the windmill, and an internal configuration to said accelerator to impart a swirling spiral motion to the wind passing therethrough as it is constricted.

Abstract: A more efficient wind power generation system is afforded by extending tower heights to several hundred meters to operate wind catching rotors and generators aligned with the wind direction at various levels along the tower. With multiple vertically cascaded wind generators and higher velocity winds at higher elevations greater power is produced as a system characterized by a small footprint. This is particularly enhanced by a single mast construction, which is supported by a dynamic guy wire tensioning system to accommodate varying lateral forces primarily caused by the change in direction of wind loads on the tower. The mast is built from modular sections connected together at articulated joints, between which the various rotors are stationed.

Abstract: An energy conversion device which benefits from forces associated with angular momentum. A mass such as fluid is directed through a conduit from one elevation to a lower elevation with the conduit configured to conform to a decreasing cross-sectional area and oriented in a spiral of substantially conical shape so that fluid entering into the conduit accelerates both by virtue of the decreasing cross-sectional area of the conduit and by the velocity added to the fluid by successively constricting the fluid to an ever tighter spiral path of lesser radius ultimately to an output of the conduit which is in communication with a converter such as a turbine. The converter has an interior passageway in axial alignment with an outlet of the conduit and includes an interior vane which coacts against the fluid exiting from the outlet of the conduit imparting rotation to the rotor which circumscribes the passageway. The rotor is supported on a bearing block and operatively couples to a stator for power output.

Abstract: The present invention relates to an full-arc admission steam turbine having its output controlled by regulating the opening of a steam regulating valve. The full-arc admission steam turbine is run at a higher efficiency than that of the full-arc admission steam turbine of the prior art by improving the drop in the internal efficiency of the turbine due to the throttle loss of the valve. Moreover, a substantially constant high efficiency is maintained for the time period from the designed point of a partial load to the rated load if the second blade stage group is selected to provide an internal efficiency substantially equal to that of the blade stage group of the prior art.
