Appl. No.:

12/806695

Inventors:

Mark Maynard - Easthampton MA, US

International Classification:

F03D 3/00

US Classification:

415 42, 415 44, 415907

Abstract:

The generator () includes an essentially cylindrical stator assembly () defining a central turbine void () in which a wind turbine () rotates to power an electrical generator (). The wind turbine () includes vanes () having a width () less than 25 percent of a diameter () of the turbine (). The turbine () defines an open void () between the vanes () for unrestricted passage of air through the wind turbine (). Non-planar stators (A-H) extend between a base and an upper truss () to strengthen the stator assembly () and to direct air exiting directional ducts (A-H) to move in a first rotational direction () within the turbine void (). A plurality of geodesic truss segments (A-H) form the base and upper trusses () to produce a strong, light-weight wind generator () that is easily assembled on-site.

Abstract:

An gas-driven generator system for generating electric power from movement of a working liquid. The system includes a gas-driven generator that includes a liquid turbine system fluidically interposed between the lower end of an elongated gravitational distribution conduit and the lower ends of plural elongated buoyancy conduits. A heavy working liquid flows from the upper ends of the buoyancy conduits and is fed into the upper end of the elongated gravitational distribution conduit. Working liquid flows down the elongated gravitational distribution conduit to actuate the liquid turbine system. An injection of refrigerant gas into the working liquid in the plural elongated buoyancy conduits induces upward flow of the working liquid. The system includes a solar thermal heating system fluidically coupled to heat exchangers that transfer heat collected by the solar thermal heating system to the working liquid through a thermal transfer fluid circuit.

Abstract:

A gaseous compression system for compressing a gas from an initial pressure to an exit pressure with a first, blower compression bank and a second, mechanical compression bank. Each compression bank has plural stages of gaseous compression with a gaseous fluid compressor and a heat pump intercooler. The heat pump intercooler comprises a cascading heat pump intercooler with a high temperature section, a medium temperature section, and a low temperature section, each temperature section with an intercooler core. Each stage of the blower compression bank has a high-pressure blower, and each stage of the mechanical compressor bank has a mechanical compressor. A final stage of gaseous compression is without a heat pump intercooler. Gas compressed by the gaseous fluid compression system can be injected into a gas-driven generator to generate electric power from movement of a working fluid induced by injection of the compressed gas.

Abstract:

An air-driven generator for generating electric power from movement of a working fluid. Upper ends of buoyancy conduits are in fluidic communication with an upper end of a gravitational distribution conduit, and a lower end of the gravitational distribution conduit is in fluidic communication with lower ends of the buoyancy conduits. An air injection system injects air into the buoyancy conduits. A closed fluid loop is formed with working fluid flowing from the gravitational distribution conduit driving a fluid turbine system that is interposed between the lower ends of the gravitational distribution conduit and the buoyancy conduits. Flow of working fluid can be induced by an injection of air into working fluid disposed in the buoyancy conduits to achieve a generation of power by actuation of the fluid turbine system. An upper chamber can remove entrained air. A Rankin Cycle Generator can receive and be actuated by exhausted air.

Inventors:

Mark Joseph Maynard - Easthampton MA, US

International Classification:

F03B 17/02

Abstract:

This invention is a renewable energy generator. This is a device for converting low pressure gas into a buoyancy force to create mechanical energy. The device consists of a round cylinder tank with a large radius containing a fluid where the aspect ratio of the round height over width greatly favors the height. Inside this tank is a submerged wheel with a plurality of cups between two supporting rings on the perimeter of the wheel. The rings are connected to a centralized hub and shaft which extend through the sides of the tank at the center. Air or gas is injected in the lower section of the tank to fill the cups and displace the fluid. The displacement of fluid creates an unbalance upward buoyancy force and rotates the wheel along the perimeter which turns the shaft and drives other devices in particular electric alternators to produce renewable electricity.
