  • Publication number: 20190014726
    Abstract: A system, apparatus and method of enhancing the growth of crops using gaseous media with deprived Oxygen content. A plant growth apparatus is disclosed including a source of Nitrogen gas (N2); a source of Carbon Dioxide gas (CO2 gas); a compressor connected to the source of Nitrogen gas and to the source of CO2 gas; and one or more gas emitters connected to the compressor and adapted to be disposed near plants in a greenhouse or other enclosure. During use, the gas emitters emit a predetermined amount of Nitrogen gas and a predetermined amount of CO2 gas, in a mixture, to the plants, whereby a diffusion gradient is created in each plant moving Oxygen gas (O2) out of the plant and enhancing photosynthesis in the plant.

  • Publication number: 20170318756
    Abstract: A system and method of optimizing Carbon Dioxide delivery to crops during high-temperature periods. The method of facilitating plant growth includes the steps of (a) determining the wilting temperature of a set of plants; (b) measuring the ambient temperature of the plants; (c) supplying CO2 gas to the plants when the ambient temperature reaches a predetermined temperature point prior to the wilting temperature of the set of plants; and (d) continuing to supply CO2 gas to the plants until the ambient temperature of the set of plants falls below the predetermined temperature point, and then discontinuing supplying CO2 gas to the plants. Temperature of the plants is measured by a temperature sensor continuously monitoring the ambient temperature of the plants. A CO2 gas applicator disposed near the plants supplies CO2. the CO2 gas applicator is connected to a controller that is connected to a CO2 gas source.

  • Patent number: 6108967
    Abstract: The present invention involves utilization of carbon dioxide, CO.sub.2, gas produced from various natural and manmade sources. Where such gas is vented as a waste by-product into the atmosphere, it is a leading gaseous emission contributing to the Earth's atmospheric greenhouse effect and ultimately to devastating global warming. The present invention can include a method of transmission, distribution and utilization of CO.sub.2 gas. This aspect of the invention includes the transmission of CO.sub.2 gas through idled natural gas pipelines during summer months and delivery of the CO.sub.2 gas to field crops to increase crops' yields. This method will increase the seasonal utilization "load factor" of natural gas pipelines during "off peak" non-heating months, when natural gas is in low demand. Further, the invention can provide a distribution mechanism consisting of a series of trunk lines with gate valves linking to primary manifolds.

  • Patent number: 5580457
    Abstract: The present invention provides a method of handling waste. In one embodiment, the invention provides a method for economically transporting waste from one location to another, treating the waste to produce a biogas, and utilizing a portion of that biogas to enhance plant growth and/or as a fuel source. In another embodiment, the method involves loading waste into the a waste-carrying vessel and transported to a remote treatment facility, where it is unloaded. The waste is then anaerobically digested at the treatment facility and a portion of the biogas resulting from the anaerobic digestion is utilized to enhance the growth of vegetation. The portion of the biogas so used is desirably relatively rich in carbon dioxide. The remaining portion of the biogas, which is desirably relatively rich in methane, and relatively carbon dioxide-poor, may then be combusted as a fuel source.

  • Patent number: 5409508
    Abstract: An economic and practical system for enhancing plant growth by delivering gaseous carbon dioxide to the plants. The vegetation is planted within an elongated trench preferably in an overstocked condition whereby the vegetation is permitted to grow sufficiently to define a closed canopy. The carbon dioxide-rich gas may be delivered to the trench by conduits beneath the level of the canopy. The trenches can include a floor and side walls which extend vertically upwardly and divergently from each other to restrict the flow of air beneath the canopy thereby minimizing the dilutive effects of the atmosphere. The trenches can also be oriented generally perpendicularly to the prevailing wind direction to minimize the tendency of the wind to carry off the carbon dioxide.
