Systems and methods for rain cloud initiation

A system configured to produce a man-made cloud and deliver the man-made cloud into the troposphere at an altitude targeted for downwind delivery of precipitation from the man-made cloud, the system being operable in conjunction with one or more airborne vessels, the system comprising:

• a water-delivery subsystem configured to deliver water from a water source to a fanning subsystem, wherein the water source is one or more of an ocean, a lake, and/or a river;
• a fuel-delivery subsystem configured to deliver oxygen and hydrogen to the fanning subsystem;
• the fanning subsystem including an intake, an output, one or more de Laval nozzles, and a de Laval turbine, wherein the intake is configured to take in the oxygen and the hydrogen from the fuel-delivery subsystem, wherein the fanning subsystem is configured to ignite the oxygen and hydrogen to produce aerosol within the one or more de Laval nozzles, wherein the one or more de Laval nozzles are configured to drive the de Laval turbine, wherein at least a portion of the delivered water is combined with the produced aerosol prior to entry into the air tube, wherein the output is configured to output the aerosol produced from the oxygen, the hydrogen, and the portion of the delivered water, and wherein the fanning subsystem is further configured to transport the aerosol from the fanning subsystem into an air tube;
• the air tube having a first end and a second end, wherein the first end is arranged at or near the fanning subsystem, wherein the air tube is configured to transport the aerosol from the first end through the air tube to the second end, wherein the second end is disposed into the troposphere by coupling the second end to the one or more airborne vessels while the one or more airborne vessels are flying in the troposphere,
• wherein the air tube has a particular length when deployed, ranging between the first end and the second end, wherein the particular length is sufficient to maintain the second end of the air tube at an altitude ranging between a few hundred feet and a few thousand feet, wherein the system is configured to deploy the air tube such that the altitude at the second end of the air tube corresponds to the altitude targeted for the downwind delivery of the precipitation from the man-made cloud,
• wherein the air tube includes multiple exhaust vents disposed between the first end and the second end, wherein individual ones of the multiple exhaust vents are configured to exhaust a portion of the aerosol from the air tube into atmosphere,
• wherein the aerosol exits the air tube at the second end such that the man-made cloud is produced by the aerosol upon exiting the air tube at the altitude targeted for the downwind delivery of the precipitation from the man-made cloud.

A method to produce a man-made cloud and deliver the man-made cloud into the troposphere at an altitude targeted for downwind delivery of precipitation from the man-made cloud, the system being operable in conjunction with an airborne vessel, the method comprising:

• delivering water from a water source to a fanning subsystem, wherein the water source is disposed at or near ground level;
• taking in, by an intake of the fanning subsystem, either:
• (i) oxygen and hydrogen, wherein the oxygen and hydrogen are ignited to produce aerosol, or else taking in one or more of:
• (ii) air,
• (iii) the delivered water, wherein the delivered water is or has been combined with the air to produce aerosol, and/or
• (iv) the aerosol produced from the delivered water;
• outputting, by an output of the fanning subsystem, either:
• (i) the aerosol produced from either the oxygen and the hydrogen or from the delivered water, or else outputting, responsive to taking in (ii), (iii), and/or (iv),
• (ii) the air, wherein the air is or has been combined with the delivered water to produce the aerosol, and/or
• (iii) the aerosol produced from the delivered water;
• transporting the aerosol from the fanning subsystem into an air tube, the air tube having a first end and a second end, wherein the first end is arranged at or near the fanning subsystem, wherein the second end is disposed into the troposphere by coupling the second end to the airborne vessel while the airborne vessel is flying in the troposphere, wherein the air tube is at least 400 feet long from the first end to the second end;
• transporting, by the air tube, the aerosol from the first end through the air tube to the second end;
• exhausting a portion of the aerosol from the air tube into atmosphere, by multiple exhaust vents disposed between the first end and the second end of the air tube;
• and
• producing the man-made cloud, by the aerosol exiting the air tube at the second end of the air tube, at the altitude targeted for the downwind delivery of the precipitation from the man-made cloud.
