Abstract:
A control system manages and optimizes a geothermal electric generation system from one or more wells that individually produce heat. The control system includes heat sensors that measure temperature and fluid flow and are placed at critical points in the wells, in piping, in a hot fluid reservoir, in a cold fluid reservoir and in a cooling system. The control system also includes pump and valve controls, generator controls, a network for gathering information and delivering instructions, and a processing module that collects information and communicates control information to each component.

Abstract:
A passive selective headset (11) characterized in that a controller accepts speech noise and warning signals from microphones (14) and allows the user to employ an "in-wire" controller (17) or an adaptive speech filter (16) to attenuate the noise from the signal fed to the speakers (12) adjacent the user's ear.
Abstract:
A method of transferring heat using a grout that has been optimized for heat transfer includes a heat conductive particulate mixed with the grout. The grout and particulate mixture includes enough particulate to form connections to create heat conductive paths. A method of treating grout so that it is resistant to the caustic environment existing at the bottom of a well, mixing an aggregate with the grout to form a mixture having a PH opposite to the caustic environment at the bottom of the well.
Abstract:
A repetitive noise cancellation system for multiple noise sources employing a controller (36) which senses radiated noise by reference sensors (35) and the status of the noise sources by position sensors (37, 38) and automatically controls one of the noise sources so that the noises being emitted from the multiple sources cancel one another.
Abstract:
A closed box loudspeaker system (9) which has the back of the loudspeaker sealed by a small closed chamber containing a gas which acts like mechanical spring connected to the loudspeaker diaphragm (1). The system avoids the problems inherent in large back chambers by altering the static pressure in the back chamber. To counterbalance the differential pressures either a spring flexible diaphragm (2) or bellows (21) is employed.
Abstract:
In combination, an electrical generation system has a condenser configured to receive a condenser cooling fluid for cooling the condenser and provide the condenser cooling fluid for re-cooling; a cooling reservoir receives are-cooled condenser cooling fluid and provides the re-cooled condenser cooling fluid as the condenser cooling fluid; and a multiphase cooling nest receives in a first cooling phase the condenser cooling fluid; and either provides a first cooling phase fluid as the re-cooled condenser cooling fluid to the cooling reservoir for recirculating to the condenser, or provides the first fluid cooling fluid for further cooling by the multiphase cooling nest, based on the temperature of the first stage cooling fluid.
Abstract:
A system and method of maximizing heat transfer at the bottom of a well using heat conductive components and a predictive model are used to design and implement a closed-loop solid state heat extraction system to conduct geo thermal heat from rock within the well. A heat conductive material inserted into the well conducts heat to the fluid heat exchanging element. The closed-loop solid state heat extraction system extracts geothermal heat from the well without exposing the rock surrounding the heat nest to a liquid flow.
Abstract:
Apparatus is provided having a heat extraction system for generating geothermal heat from within a drilled well, comprising: a heat conductive material injected into an area within a heat nest near a bottom of a drilled well between a heat exchanging element and rock, and any fluid around the rock, surrounding the heat nest to form a closed-loop solid state heat exchange to heat contents of a piping system flowing into and out of the heat exchanging element at an equilibrium temperature at which the rock surrounding the heat nest and generating the geothermal heat continually recoups the geothermal heat that the rock is conducting to the heat conductive material.
