ARTIFICIAL RAINMAKING BY HIGH POWER LASER INITIATION ENDOTHERMIC REACTIONS THROUGH DRONE AIRCRAFT REMOTE CONTROL SYSTEM

Technical field of invention:

[001] The present invention in general relates to artificial rain making by using high power laser initiation endothermic reactions through Drone Aircraft remote control system.

Background of the invention:

[002] Condensation is the basic need for water drop formation. Example: Take two glasses with clean outer surface one with normal water and another with ice pieces and place them on a table in winter season. After sometime you can observe water droplets on the outer surface of the glass which contains ice but not in the other. This is due to the condensation process that occurred in that ice glass without any seeding. Hence condensation is the basic need for the water drop formation. When natural rainfall occurs in the atmosphere no seeding process takes place.

[003] The conventional seeding process used for artificial rain making can be used only for cold rainy clouds, but our proposed process is equally successful for warm white clouds. In our process, condescension is by endothermic reactions. We have proved this in our Laboratory. Seeding process is expensive and harmful to mankind because it brings harmful chemicals on earth along with rain.

Natural evidence:

[0011] Present invention actually works on a method which emulates rain formation mechanism in nature after lightning. On several occasions it has been found that precipitation follows after lightning. Golde (1977) from a number of radar observations has reported that intense precipitation is not even present in the clouds before the first discharge but it develops abruptly in the same region after discharge from which the lightning flashes originate. Battan (1981) has observed very rapid growth of precipitation particles/ice crystals caused by electrical forces following a lightning discharge. In many cases the on-set of strong electrification follows the appearance of heavy precipitation within the cloud in the form of hail stones (Wallance and Hobbs, 1977). The correlation between lightning and precipitation is as follows: heavy gushes of rain or hail often reach the ground in 2-3 min. after the lightning flash and it is evidenced that lightning is the cause rather than the result of the rapid intensification of the precipitation (Mason, 1975). It is further speculated that the rapid intensification of the precipitation from about 1mm/h to 50mm/h in this 2-3 min period is brought about by a greatly accelerated rate of coalescence of water drops under the influence of electrical forces by a mechanism that is obscure and has no convincing experimental or theoretical base (Mason, 1971). From the above work it is clear that precipitation is formed after lightning.

[0012] In lightning, temperature rises as high as 30,000K in fraction of a second. At this high temperature both dissociation and ionization of N 2 and 02 takes place. But for the formation of precipitation, a temperature as low as ~ -10K is needed. How a region which rose to a temperature of ~30,000K attains a temperature of ~ -10K? Who removes the heat? That means after lightning, some mechanism occurs which cool the medium. The mechanism is occurrence of endothermic reactions which cool the atmosphere. This cooling will create CCN (clouds condensation nuclei) in cloud and produce tiny water droplets in the atmosphere. These tiny water droplets then will act as natural seed for the formation of rain drops in the atmosphere (Drake2006).

Practical Evidences:

[0013] Carls and Brock (1987) did an experiment in which atmosphere was heated by a laser pulse up to 1600 to 2800 K. They observed water droplet formation in the atmosphere. They postulated that water droplets were formed by ionization process. This is partly true because they did not consider dissociation and the occurrence of endothermic reactions, which are responsible for cooling and capable of CCN formation. Again in the conclusion of the said paper, he predicted that the air is shock heated to temperatures high enough to cause ionization. If the ionized air is subjected to more radiation, avalanche breakdown of the air can occur. This is similar to breaking of N 2 and 02 molecules because air contains 77% N 2 and 23% 02, which is responsible for endothermic reaction and condensation takes place. Our simulation substantiates the theory that shock heating of air can be at least partly responsible for aerosol-enhanced breakdown.

[0014] In the laboratory, we did an experiment in a chamber where lightning was created by a high voltage electric spark. We noticed formation of water droplets on the surface of the chamber. The results have been published (Chopkar and Chakrabarty2008, Chopkar et al. 2010).

[0015] Rohwetter et al. (2010) have shown that ionized filaments (like a cable) generated by ultra-short wave (Visible, Infra Red region) laser pulses are able to induce water-cloud condensation in the sub-saturated atmosphere in the altitude region between 45 and 75m resulting in rain.

[0016] Yoshihara et al. (2007) have shown that the pulsed UV-laser irradiation of ambient air induces the formation of water droplets or small ice particles in the laboratory. They also observed that the atomic oxygen which is formed in this process quickly reacts with oxygen molecules to form ozone. In their experiment ozone is formed due to endothermic process by which condensation takes place and CN (condensation nuclei) is formed which produces water droplets or ice crystals.

[0017] It may be mentioned here that a group at Indian Institute of Tropical Meteorology, Pune who is experimenting with lidar, has also observed that a few drops of water fall after the laser beam is shot in the atmosphere.

[0018] Recently, in U.S.A. at the University of Central Florida in Orlando, Development of this technology (Laser makes rain) was supported by a $7.5 million grant from the U.S. Department of Defense. During a rainstorm, particles inside a cloud build up static electricity and release it as lightning. Meanwhile, tiny water droplets stick together until they are heavy enough to fall to the ground. Scientists want to recreate this process with lasers to produce rain when and where it is needed (Inside Science TV).

[0019] Although various research works prove that condensation takes place in laboratory cloud chamber, not much scientific justification is provided about what phenomena is responsible for that condensation? In our studies we have analyzed and observed that only and only endothermic reaction is responsible for the said condensation.

[0020] In the atmosphere, after lightning, heavy rain fall occurs. In lightning phenomena condensation takes place by initiating endothermic reactions and tiny water drops formed, these tiny water drops collide with each other due to acceleration and turbulence by wind force to form big rain drops, these rain drops act as natural seeding for another sets of rain drops. In this way, chain process occurs with heavy rain fall. Above lightning phenomena, is used in the present invention for artificial rain making by using plasma laser pulse in the atmosphere, through Drone air craft's with remote controlled system.

[0021] The advantage of this method is, it is environmentally clean, one time investment so it is economical, can be turned on and off at will, and can be precisely positioned. It will be movable on drone air craft remote control system. The present system is targeted to create artificial rainfall by high power laser pulse in the atmosphere, at any place, at any time, as per our human need, for green revolution, in the whole world.

Summary of the invention:

[0032] The mega UAV fitted with pen tax digital camera is used for taking high resolution images on demand. Mega UAV is controlled by autopilot along with pre-programmed ground control software or can be manually taken off using simple joy stick working at radio frequency range.

[0033] For penetrating deeper inside the clouds when triggered from ground, LASER beams are not efficient. To trigger ionization process and further initiate endothermic reaction instead of sending light beam from ground to cloud, UAV is equipped with plasma frequency releasing system and is sent to the inner of the cloud mass density. UAV system goes deep inside the cloud mass and releases single high power LASER pulse in atmosphere.

[0034] Drone systems are used to create acceleration and turbulence by wind force and tiny water particles collides and becomes bigger rain drops. Such bigger rain drops acts as seed to form another rain drops and raining occurs.

[0038] In order that the manner in which the above-cited and other advantages and objects of the invention are obtained, a more particular description of the invention briefly described above will be referred, which are illustrated in the appended drawing. Understanding that these drawing depict only typical embodiment of the invention and therefore not to be considered limiting on its scope, the invention will be described with additional specificity and details through the use of the accompanying drawing.

Detailed description of the invention:

[0039] The present system is designed to create artificial rain by initiating endothermic reactions in the cloud using a high power laser pulse through drone air craft remote control system. The advantage of this method is, it is environmentally clean, one time investment, can be turned on and off at will, and can be precisely positioned and cover a cloudy wide area according to atmospheric condition.

[0040] When a laser pulse of wavelength, k and energy, hv (v = 1/k and h is Planck's constant) is shot in the atmosphere, depending on the value of its energy, it can dissociate (break the bonds of) Nitrogen (N2) and Oxygen (02) and ionize them as follows:

Dissociate: N2 + hv-+N* + N .............. (1) 02 + hv O* + O .............. (2)

Ionize: N2+ hv - N2++ e- .............. (3) O2 + hv-+ 02 + e~ .............. (4)

Energy required to dissociate 1 molecule of N2 and 1 molecule of 02 = 2.25x10-18 Joule. Energy required to ionize 1 molecule of N2 and 1 molecule of 02= 4.44x10-18 Joule.

[0041] Hence the energy required to dissociate 1 molecule of N 2 and 1 molecule of 02 is about half of that required to ionize them. Therefore, when a laser pulse is shot in the atmosphere, it will first dissociate N 2 and 02 and if energy still remains then it will ionize them.

[0042] After bond breaking (dissociation, reactions 1and 2), two atoms of N 2 (N*, N) and two atoms of 02 (0*, 0) are formed. Among them atoms N* and 0* are in excited state and hence are unstable. They immediately react with some gases to come to ground state and form stable NO and 03 as follows:

N* + 02 + ( 43.2 kcal/mol) -+ NO + 0 .......... (5) 0* +02+ N 2 + (67.6 kcal/mol) - 03 +N2 .......... (6)

[0043] Both reactions (5) and (6) are endothermic and absorb a large amount of heat (43.2

+ 67.6 = 110.8 kcal/mol) from the surrounding air. As a result, the air becomes cooled below the condensation temperature and fine water particles are formed, cloud seeding takes place and it rains. There is another possibility. In reactions (3) and (4), positive ions, N2+ and 02+ and electrons, e- is formed. Positive ions, N2+ and 02+ will quickly react with water molecules and form big ions like H(H 20), etc and electrons, e~ will quickly react with many gases to form big negative ions like N03(H 2 0)n etc. The value of "n" could be as large as 25. These big positive and negative ions may act as seed and create rain.

Best Method of performance of the invention: Recording of atmospheric parameters:

[0044] Measurement of atmospheric parameters like percentage of humidity, temperature, and pressure and wind velocity at different height before and after sending the laser pulse will be done by weather forecasting system or satellite receiving systems. Data to be recorded (before and after passing laser pulse)

Date::.........Day::..........Tim e::... AM........ PM Location:: ...........

[0045] Above parameters will be recorded by sending a laser of particular wavelength and then we will vary the wavelength of laser Pulse and record the same parameters so that the data can be collected for ready reference for artificial rain making at that particular place.

Observation of cloud condensation and precipitation formation:

[0046] Videos and pictures of cloud condensation and precipitation will be recorded by cameras before, during and after laser induced precipitation.

Measuring liquid water content in the cloud:

[0047] Liquid water content in the clouds will be measured by sending quad-copter at various heights.

Laser experiment:

[0048] After recording atmospheric parameters and water content of the clouds on any given day at a particular date, time and location; different wavelength of lasers are sent to atmosphere and resulting precipitation is recorded using rain gauge. For example, on a given day after recording percentage of humidity, temperature, and pressure and wind velocity; laser pulse of various intensity and different wavelengths are transmitted and resulting precipitation will then be noted. Through this process following information is obtained: INTENSITY OF LASER BEAM= --- nm (wave length X)

[0049] In this way, various parameters can be collected by passing a laser pulse of particular wavelength and then by varying the wavelength of laser Pulse average rain fall at different rain gauge stations can be observed. This constitutes optimum value of wavelength and intensity of the laser Pulse which will give the maximum average rain fall.

Analysis:

[0050] At any given level of humidity range, the data of laser intensity (wavelength) versus % of water drop formation can be observed. After calculating optimum laser intensity at a given humidity ranges, relationship between humidity range and optimal wavelength to cause precipitation at that humidity range can be analyzed. This reading is used to design the final laser induced rain making system optimized to cause maximum possible rainfall at a given level of humidity
