System and method for irrigation using atmospheric water
First Claim
1. A method for delivering water to one or more plants wherein each plant resides at least partially in a quantity of soil, and is proximate to air that contains water vapor, said method comprising the steps of:
- operating a condensing unit at condensing intervals to convert amounts of the water vapor into water in liquid form;
storing said water in liquid form in a reservoir, wherein the reservoir is connected to an irrigation system configured to selectively deliver water from the reservoir to each of the plants;
accessing a database of horticultural information for an amount of water needed by a plant type of the one or more plants;
generating one or more estimates of the moisture content of said quantity of soil, during a first specified time period;
computing one or more watering intervals during the first specified time period, wherein each watering interval is computed, at least in part, as a function of values contained in the horticultural database, and also as a function of the estimates of moisture content;
gathering data pertaining to said plant water need, wherein said gathered data is used to determine at given times whether it is necessary to operate the condensing unit; and
operating the irrigation system to deliver water to each of the plants during each of the watering intervals.

Abstract
An embodiment of the invention delivers water to plants of a specified type which reside in a quantity of soil. A condensing unit is operated at optimum intervals to condense water vapor in the air into water in liquid form. The condensed water is stored in a reservoir connected to an irrigation system, which can deliver water from the reservoir to each of the plants. A database is established that contains horticultural information, wherein the horticultural information comprises a set of values representing the water needed by plants of the specified type at different stages of growth. Estimates of soil moisture content are generated during a specified time period. Optimum watering intervals are computed during the specified time period, at least in part, as a function of the set of values contained in the horticultural database, and also as a function of the estimates of moisture content. The irrigation system is operated to deliver water to each plant during respective optimum watering intervals.

12. A method of irrigating, comprising:
-
condensing, by a condensing unit, amounts of water from water vapor; operating the condensing unit for a condensing interval during a time period for a level of efficiency based on temperature data and dewpoint data forecasted for that time period, and an amount of water needed by a plant type of the plant in the soil; determining moisture content of soil subject to irrigation; and selectively storing the condensed water and distributing the condensed water to one or more plants based on the moisture content of the soil and the amount of water needed. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. Apparatus for delivering water to one or more plants wherein each plant resides at least partially in a quantity of soil, and is proximate to atmospheric air that contains water vapor, said apparatus comprising:
-
a condensing unit which is operable at condensing intervals to convert amounts of the water vapor into water in liquid form; a reservoir for selectively storing said water in liquid form; a processing means associated with a database that contains horticultural information for an amount of water needed by a plant type of the one or more plants, wherein the processing means receives one or more estimates of the moisture content of said quantity of soil, during a specified first period of time, computes one or more watering intervals during the specified first period of time, each watering interval being computed, at least in part, as a function of values contained in said horticulture database, and also as a function of said estimates of moisture content, and gathers data pertaining to said plant water need, wherein said gathered data is used to determine at given times whether it is necessary to operate the condensing unit; and an irrigation system operated by said processing means to deliver water to each of the plants during each of the watering intervals. - View Dependent Claims (20, 21)
