Abstract: The present disclosure provides methods whereby products can be prepared in a manner that adds value to the products beyond the market value of such products, and the present disclosure further provides methods for optimizing production of products toward processes that yield a positive net result. The methods for preparing a product can utilize a synthesized oxide compound and, depending upon the order of combination, can modify the synthesized oxide compound by combination with both of carbon dioxide and a secondary component.

Abstract: A method for transferring thermal energy to a separate endothermic process includes: (a) providing a carbon dioxide (CO2) stream and a carbonaceous fuel to a heater; (b) reacting the carbonaceous fuel in the heater to produce a heated stream; (c) transferring heat from the heated stream to the separate endothermic process; (d) separating the CO2 stream from the heated stream after (c); and (e) recycling the CO2 stream to the heater after (d).

Abstract: The present invention provides methods and system for power generation using a high efficiency combustor in combination with a CO2 circulating fluid. The methods and systems advantageously can make use of a low pressure ratio power turbine and an economizer heat exchanger in specific embodiments. Additional low grade heat from an external source can be used to provide part of an amount of heat needed for heating the recycle CO2 circulating fluid. Fuel derived CO2 can be captured and delivered at pipeline pressure. Other impurities can be captured.

Abstract: The present disclosure provides systems and methods that combine direct capture of one or more moieties from a gaseous mixture with one or both of calcium oxide production and power production. The systems and methods can utilize combinations of a capture unit, a regeneration unit, a calcination unit, a slaking unit, a heat exchange unit, a separation unit, and a power production unit. The present disclosure provides the ability to remove carbon dioxide and other moieties from air or other gaseous mixtures in a truly carbon negative manner by utilizing electricity from a power production unit that is operated in a carbon neutral or carbon negative manner and simultaneously provide useful products, such as calcium oxide and calcium hydroxide.

Abstract: The present disclosure relates to a launch system, a launch vehicle for use with the launch system, and methods of launching a payload utilizing the launch vehicle and/or the launch system. The disclosure can provide for delivery of the payload at a terrestrial location, an Earth orbital location, or an extraorbital location. The launch vehicle can comprise a payload, a propellant tank, an electrical heater wherein propellant, such as a light gas (e.g., hydrogen) is electrically heated to significantly high temperatures, and an exhaust nozzle from which the heated propellant expands to provide an exhaust velocity of, for example, 7-16 km/sec. The launch vehicle can be utilized with the launch system, which can further comprise a launch tube formed of at least one tube, which can be electrically conductive and which can be combined with at least one insulator tube. An electrical energy source, such as a battery bank and associated inductor, can be provided.

Abstract: The present disclosure relates to systems and methods for power production utilizing an ion transfer membrane (ITM) unit. An air stream and a fuel stream can be passed through the ITM unit so that the fuel is at least partially oxidized or combusted to form an outlet stream comprising CO2. The CO2 stream can be compressed and expanded to generate power.

Abstract: The present disclosure provides an integrated power generating system and method that combines combustion power generation with solar heating. Specifically, a closed cycle combustion system utilizing a carbon dioxide working fluid can be increased in efficiency by passing at least a portion of a carbon dioxide working fluid through a solar heater prior to passage through a combustor.

Abstract: A system and method are provided that sit at the intersection of high bandwidth mobile communications and light detection and ranging (LIDAR). The system and method expand on a diverged-beam free space optical system (DBFSO) and solves the LIDAR cost problem by describing a combined LIDAR/DBFSO system. One integrated hardware system provides the capability of both LIDAR and DBFSO, and in many configurations, both capabilities can operate at the same time, while reducing cost and complexity associated with two separate systems. The system can be stationary or mobile, and apply to both scanning and fixed configurations.
