Abstract: A growing system is equipped with a mixing box that features a PLC-controlled cooling coil and a heating coil in series. Gaseous inputs include air and CO2. The coils facilitate condensation and maintain relative humidity and temperature in an acceptable range. An absorption unit or other chilled liquid source supplies chilled liquid for the cooling coil. Engine or boiler combustion provides hot liquid to the heating coil and CO2-containing exhaust. Condensate is collected for reuse. The output to a growing space is a temperate low relative humidity CO2-enriched stream optimal for plant health.

Abstract: A growing system (e.g., greenhouse) is equipped with a mixing box that features a PLC-controlled cooling coil and a heating coil in series. PLC regulated inputs include air and CO2-containing exhaust. The cooling coils in series facilitate condensation to maintain relative humidity in an acceptable range. Substantial cooling is necessary to achieve sufficient condensation and temperature reduction. Condensate is collected for reuse. The heating coil heats cooled CO2-enriched air to an acceptable temperature for plant health. The output is a temperate low relative humidity CO2-enriched stream optimal for plant health.

Abstract: A growing system (e.g., greenhouse) is equipped with a mixing box that features a pair of PLC-controlled cooling coils and a heating coil in series. PLC regulated inputs include air and CO2-containing exhaust. The cooling coils in series facilitate condensation to maintain relative humidity in an acceptable range. At least two stages of cooling are necessary to achieve sufficient condensation and temperature reduction. Condensate is collected for reuse. The heating coil heats cooled CO2-enriched air to an acceptable temperature for plant health. The output is a temperate low relative humidity CO2-enriched stream optimal for plant health.

Abstract: A scalable vertical conveyor cyclically carries planters (i.e. trays) in a closed path through a sub-floor dark zone and an above floor illuminated zone. A dark zone, formed below a floor, provides a dark region that simulates nighttime. The rate of travel simulates a growing day, such as, but not limited to a 24 hour growing day. One or more lighting, irrigation and fertigation elements are provided in the illuminated zone. Optionally, the portion of the conveyor in the dark and illuminated zones are adjustable.

Abstract: An efficient scalable networkable grow light system ensures that a DLI suitable for optimal plant growth without causing heat stress is met by selectively illuminating lighting elements of determined wavelengths, and adjusting intensity of the lighting elements, and adjusting the height of an assembly containing the lighting elements, if sensed ambient light is inadequate to meet the DLI. A hoist adjusts height to provide full illumination without causing heat stress, while reducing inefficiency due to excessive distance. If sensed ambient lighting is sufficient to meet the DLI, supplemental lighting is not activated.

Abstract: A greenhouse environment control system generates a CO2-enriched air which is supplied to a greenhouse at a controlled temperature suitable for plant growth. An absorption chiller reduces temperature of a CO2-containing stream of processed gasses from an engine. A mixing and blending unit maintains CO2 at an acceptable concentration for enhanced plant growth and human occupation. An HVAC system modulates temperature and positively pressurizes the greenhouse with the CO2-enriched air to reduce risk of contaminant intrusion. Misting further controls temperature. Retractable shades regulate light supplied to plants and solar gain.

Abstract: A method of using internal combustion engine exhaust in a combined cycle power plant is disclosed, wherein the quality and distribution of exhaust to the boiler space of a steam generated electric power plant is controlled to achieve greater system efficiencies. Outside air is blended only with that portion of the exhaust that passes through the burner ports as secondary or higher level combustion gas. The remainder of the exhaust is provided to the boiler space by a route other than through the burner.
