[0004] DESCRIPTION

[0005] AREA OF INVENTION

[0006] The present invention relates to a method that can counteract climate change, wherein desalination of seawater is used for irrigation in agriculture and agricultural land is irrigated and fertilized in a precisely metered manner using GPS.

[0007] BACKGROUND OF THE INVENTION

[0008] Seawater desalination processes are state of the art, and the importance of nutrients in water is also partially understood. Science tells us that sea levels are rising. This development poses a significant threat to our climate. Lowering sea levels could help regulate the climate and reduce heat. Many lakes have already dried up, and deserts are steadily expanding.

[0009] Canals, ditches, and rivers must be stopped and cleaned to prevent water from flowing unused and polluted into the sea. Instead, we should use this water for irrigation. Seawater only needs to be partially desalinated, as salt in certain quantities is beneficial for agriculture. This would allow us to contribute to irrigation, increase yields, and raise the groundwater level, thus sustainably strengthening local agriculture. 17.09.2024

[0017] S0122 / TM

[0018] Salt is heated, wherein the salt serves as an energy storage medium and / or wherein the device has a sensor in the agricultural area which transmits data about the plants and the agricultural area, in particular the soil moisture, via the Internet and / or to a satellite, in particular to determine the required nutrients and the required irrigation.

[0019] As a fourth aspect, a system is provided comprising: a solar collector for generating electricity for a network of buildings and installations from solar radiation and a device for desalinating seawater by osmosis and / or distillation, wherein the solar collector transfers electrical energy that is not fed into the network to the desalination device for the production of fully or partially desalinated water and salt and / or wherein the solar collector heats salt, the salt serving as an energy storage medium and / or wherein the device has a sensor in the agricultural area that transmits data on the plants and the agricultural area, in particular soil moisture, to a satellite, in particular for determining the required nutrients and irrigation.

[0020] As a further aspect of the invention, a method for the ecologically optimal management of agricultural land is provided, comprising: fertilizing and irrigating agricultural land and transmitting the locations and quantity of fertilization and / or irrigation and the quantity and growth stage of the cultivated crops via GPS to a satellite.

[0021] Advantageously, a method for the ecologically optimal management of agricultural land is provided. The aim is to supply all necessary nutrients for healthy plant growth in the extracted and partially desalinated seawater, while simultaneously ensuring a sustainable water supply. Continuous monitoring of the areas ensures that the plants always receive the optimal amount of nutrients to meet the needs of the ecosystem. (17.09.2024)

[0022] S0122 / TM

[0023] The aim is to promote growth and reduce the use of medication in humans and animals. Particular care is taken to never increase nutrient levels beyond the required optimum in order to avoid polluting the water.

[0024] Precise location tracking allows for irrigation and fertilization that perfectly matches the needs of the crops, thus preventing waste. This innovative method therefore enables the careful use of resources, preventing adverse effects from resource overuse.

[0025] As a further aspect of the invention, a device for applying one of methods 1 to 7 is provided, comprising: a nozzle for dispensing water and / or fertilizer and a GPS means, wherein the means transmits the location and quantity of the dispensing through the nozzle to a satellite, wherein the GPS means is arranged on the nozzle and / or in an agricultural area.

[0026] As a further aspect of the invention, a device is provided comprising: a wind turbine for generating electricity for a network of buildings and facilities and a device for desalinating seawater by osmosis and / or distillation, wherein the wind turbine transfers electrical energy that is not fed into the network to the desalination device for the production of fully or partially desalinated water and salt and / or wherein the wind turbine heats salt, the salt serving as a heat storage medium and / or wherein the device has a sensor in the agricultural area that transmits data on the plants and the agricultural area, in particular soil moisture, to a satellite, in particular for determining the required nutrients and irrigation.

[0030] Instead of a solar collector, a solar panel or other device for generating heat or electrical energy from solar radiation can be used as an alternative or additional option.

[0031] In a combined system, wind turbines could both feed electrical energy directly into the grid and store excess energy in a salt storage system. Salt, in its molten form, can be used as a medium for storing thermal energy. When excess energy, for example from wind turbines, is available, it can be used to heat the salt. The salt then stores the heat, which can later be released as needed, for example to evaporate water and thus drive a turbine to generate electricity. This principle can alternatively be applied with excess energy from solar panels.

[0040] According to an exemplary embodiment of the invention, a method is provided comprising the steps of: fertilizing and / or irrigating the crops of an agricultural area, specifically adapted to the 17.09.2024

[0041] S0122 / TM according to the respective requirements and accurate to the square meter, and if necessary individually different for each square meter.

[0042] According to an exemplary embodiment of the invention, a method is provided comprising the steps of: partial desalination of seawater by osmosis or distillation for irrigating crops.

[0043] According to an exemplary embodiment of the invention, a method is provided comprising the step of complete desalination to obtain drinking water for humans.

[0044] According to an exemplary embodiment of the invention, a method is provided wherein the salt obtained from the desalination of seawater is used as an energy storage medium.

[0045] According to an exemplary embodiment of the invention, a method is provided wherein the method for the water constitutes a closed cycle in that unused water flows back into the sea, wherein the groundwater is not included in the method and / or cycle, whereby the groundwater level is not affected by the method.

[0046] According to an exemplary embodiment of the invention, a method is provided wherein the fertilizer is part of the cycle and / or wherein the fertilizer does not enter the groundwater.

[0047] According to an exemplary embodiment of the invention, a method is provided comprising the steps of: introducing seawater into a collection basin, evaporating the seawater and condensing the water vapor to produce drinking water or generating the water by osmosis with a semipermeable membrane.

[0048] Advantageously, the extracted salt can be used as an energy storage medium. 17.09.2024

[0049] S0122 / TM

[0050] Reverse osmosis offers the advantage of directly producing partially desalinated water. This eliminates the need to mix condensed water with seawater to provide sufficient water for agricultural areas that do not require fully desalinated water.

[0051] According to a further embodiment of the present invention, a method is provided comprising the step of mixing drinking water with seawater so that the resulting water is sufficient for irrigating an agricultural area.

[0052] Mixing with seawater allows for a higher quantity of water to be obtained for irrigating agricultural land, with the aim of achieving a water quality that is optimal or just sufficient for plant growth.

[0053] Advantageously, only the water currently needed is produced, so that fully desalinated seawater is used exclusively as drinking water for humans. Partially desalinated water is sufficient for irrigating agricultural land, thus limiting the energy required for desalination.

[0054] According to a further embodiment of the present invention, a method is provided wherein the obtained salt is used as an energy storage medium.

[0055] When the salt extracted from seawater is mixed back into water, heat is released. This energy, in the form of heat, can be used to drive a turbine.

[0056] According to a further embodiment of the present invention, a method is provided wherein the method for the water has a 17.09.2024

[0057] S0122 / TM represents a closed loop and / or where the groundwater is not included in the process and / or loop.

[0058] Advantageously, desalination produces only as much water as is currently needed. In this sense, a just-in-time system for agriculture is implemented, requiring the lowest possible energy input. The produced water is used directly for irrigation, eliminating the need to pump groundwater.

[0059] According to a further embodiment of the present invention, a method is provided wherein the fertilizer is part of the cycle and / or wherein the fertilizer is kept in the cycle and / or does not enter the groundwater.

[0060] Fertilizer is applied, with GPS enabling precise dosing as needed. This prevents over-fertilization, which could, for example, lead to groundwater contamination.

[0061] One aspect of the invention is the provision of a method that contributes to climate improvement. This involves desalinating seawater and using it for agricultural irrigation. Advantageously, this can raise the groundwater level back to normal, as there is no need to pump drinking water from the ground, since the desalinated seawater can be used as drinking water.

[0062] According to the invention, agricultural analysis is performed using GPS, with agricultural machinery being equipped with GPS-enabled transmission instruments. In particular, plant development can be determined via GPS and centrally recorded and processed in a computer. This makes it possible to implement a fertilizer and crop protection plan with square meter precision, thus enabling intensive agriculture without soil depletion. Specifically, this allows for achieving optimal yields throughout the entire theoretically possible harvest period. Thanks to the square meter-precise monitoring for the relevant agricultural area, the optimal fertilization time, irrigation, and fertilization duration can be determined, thus preventing over-fertilization. High nitrate levels in the groundwater due to over-fertilization are also avoided. This enables the best possible yields.

[0063] Seawater desalination produces salt as a residue, which can be used as an energy storage medium. Furthermore, the evaporation of the seawater, which leaves behind the salt as a residue, can drive turbines with the rising steam, thus recovering some of the energy input into the evaporation process.

[0064] The individual features can of course also be combined with each other, which can sometimes result in advantageous effects that go beyond the sum of the individual effects.

[0077] DETAILED DESCRIPTION OF EXAMPLE EXECUTIONS

[0078] Fig. 1 shows the method according to the invention, in which a tractor 4 with a device 5 sprays a cultivated area with water and / or fertilizer. The device 5 has means 7 through which data communication via satellite 1 takes place via a satellite dish 2. This allows the precise location and quantity of fertilization and irrigation to be determined, down to the square meter according to the invention, and further refined based on the evaluation of the results. The tractor can additionally be equipped with GPS so that its route can be tracked and its journeys recorded.

[0079] Fig. 2 shows stationary means 14 for irrigation and fertilization, which can maintain data communication with satellites 1 via GPS. This allows the crops to be supplied with water and / or fertilizer according to local conditions and requirements. The invention describes, in particular for mobile and / or stationary operation, a nozzle for water and / or fertilizer that can be controlled by a means 7, which enables data communication via a satellite 1. The nozzle can be designed to dispense only water, or only fertilizer, or a water-fertilizer mixture, or selectively both fertilizer and water. 17.09.2024

[0080] S0122 / TM

[0081] Fig. 3 shows a device 7 according to the invention for separating water and / or fertilizer, which can be used in stationary or mobile applications. The device 7 comprises a satellite dish 2, which can enable data transmission via a satellite 1.

[0082] Fig. 4 shows a plant for producing drinking water with a collection basin 12 into which seawater 13 can be introduced. This seawater 13 is heated, for example, by irradiation 9, causing the water 10 to evaporate. This evaporated water can then be collected and used to condense water for irrigating agricultural land. The salt obtained through desalination is an energy storage medium to which heat can be supplied, thus acting as a heat storage device.

[0083] Fig. 5 shows the entire process according to the invention, which enables a closed cycle for the irrigation of agricultural land, thus eliminating the need to extract groundwater and ensuring that the groundwater level 17 remains unaffected by agricultural activity. According to the invention, the water for agriculture is obtained exclusively from the desalination of seawater 8. Another important aspect of the process according to the invention is the targeted use of the extracted water, thus eliminating the need for additional groundwater extraction. Desalination of the seawater can be achieved by evaporation and condensation or by osmosis using a semipermeable membrane.

[0084] Fig. 6 shows a schematic representation of the method according to the invention, wherein agricultural vehicles 22 collect data on the agricultural land and transmit this data to a satellite 1. This data can be compared with an existing plan 23 on soil quality and the required fertilization. After evaluation, for example by a computer on Earth, the satellite 1 can then transmit data on where and with what intensity irrigation and fertilization take place. Advantageously, this can be very locally targeted. 17.09.2024

[0085] S0122 / TM, so that the crops and agricultural land can be supplied according to the actual local requirements. According to the invention, the seawater 8 is desalinated in two steps. First, the seawater 8 is desalinated to a degree that makes it suitable for irrigating agricultural land. If drinking water is required by humans, the water is desalinated to drinking water quality in a second step. Salt is obtained through the desalination of the seawater, which can be used as an energy storage medium.

[0086] Fig. 7 shows a combination according to the invention of a wind turbine 24 with a desalination plant 25, wherein desalination can be carried out by evaporation and condensation of the seawater or by osmosis. Advantageously, generated electricity, when not needed, can be transferred to the desalination plant 25, which can use it to produce drinking water and salt. The salt can be considered an energy storage medium, the energy from which can then be called upon when, due to a lull in wind power, the energy demand cannot be met by the wind turbine 24.

[0087] Fig. 8 shows solar collectors 26 that can transfer energy to the desalination plant 25 when there is no energy demand. If there is an energy demand during darkness, the salt obtained through desalination can be used as an energy storage medium and its stored energy can be accessed.

[0088] The invention therefore proposes a two-stage desalination process, in which low-level desalination is sufficient for irrigating agricultural land, while high-level desalination is required to obtain drinking water. In this way, agriculture and people can be supplied with water without unnecessarily consuming excessive amounts of energy. The salt obtained through desalination serves as an energy storage medium. Furthermore, the invention enables targeted irrigation and fertilization through the use of a Global Positioning System (GPS), thereby preventing over-fertilization and the resulting pollution of groundwater. 17.09.2024

[0089] S0122 / TM

[0090] The concept according to the invention enables the supply of water to people and agricultural land, whereby groundwater can be essentially dispensed with, so that the groundwater level is no longer burdened.

[0091] The particular aspect of the invention is that a cycle is created in an overall system which begins with the desalination of seawater and continues with the targeted, metered use of the extracted seawater, whereby only a small amount of water is required and the groundwater level can be kept constant.

[0092] According to the invention, a plant protection area is created so that the plants receive sufficient fertilization throughout the entire growing season. Over- or under-fertilization can be ruled out. There is no risk of groundwater contamination due to the fertilization.

[0093] The invention can therefore counteract increasing soil erosion, groundwater depletion, and soil depletion. One aspect of the invention is the retention of organic materials on agricultural land, which creates new humus that can store CO2 in the soil.

[0094] Desalination can be achieved through the evaporation and condensation of seawater or through osmosis using a semipermeable membrane. Osmosis, in particular, allows for partial desalination, which is sufficient for using the recovered water for irrigating agricultural land.

[0095] Advantageously, the invention combines the sustainable use of seawater with the optimization of agricultural land use. According to the inventive method, seawater is extracted and purified so that it can be used as drinking water and for irrigating agricultural land. This advantageously allows for a reduction in the amount of seawater.

[0096] S0122 / TM

[0097] Sea level can be reached. Furthermore, fewer dikes will be needed in the future, and the groundwater level can be raised again. According to the invention, coastal protection can therefore be improved, agricultural production increased, and the long-term water supply secured.

[0098] The inventive process begins with the extraction of seawater, which is first cleaned of debris and dirt. Some of the cleaned seawater can be used for irrigating agricultural land. The remaining water is desalinated in a central desalination plant.

[0099] According to the invention, combine harvesters or agricultural vehicles are used to collect data on yield and harvest location. This information allows for precise decisions regarding the application of fertilizers and pesticides. Satellite-based monitoring also serves this purpose, with the data collected by the combine harvesters or agricultural vehicles being transmitted via satellite to a central evaluation station.

[0100] Advantageously, combine harvesters and other agricultural vehicles can analyze field data and monitor the current condition of plants and soil. Additionally, sensors can be installed in the soil to receive data from satellites about soil moisture and water requirements. This allows for optimal water allocation to irrigate agricultural land, ensuring optimal crop care.

[0101] Advantageously, the water is enriched with nutrients before irrigating agricultural land, with the nutrients being adjusted according to the plant species, thereby increasing the yield and growth of the crops. 17.09.2024 S0122 / TM

[0102] According to the invention, the crops can receive an optimally adjusted amount of irrigation by evaluating the data from the combine harvester or agricultural vehicles.

[0103] Seawater desalination produces salt, which can be used as an energy storage medium in agriculture or industry.

[0104] Seawater desalination means separating the water from the dissolved salts, which is achieved through reverse osmosis or distillation. The result is pure water and brine, which contains the salts and minerals. The salt can be extracted from the brine and processed into a transportable form.

[0105] One method of desalination is distillation by evaporation. This process allows the water to be completely removed from the highly saline brine, yielding dry salt, which is an excellent and easily transportable energy storage medium. The remaining water can be extracted from the brine, particularly in so-called evaporation ponds. Alternatively, the brine can be discharged back into the sea or used as a starting material in the chemical industry. An additional benefit is the extraction of important minerals from the brine, namely magnesium, lithium, and potassium. Lithium is particularly useful for battery production, and potassium can be used as a fertilizer.

[0106] The extracted salt can be stored, in particular, in salt storage facilities, which are preferably located near transformers and energy infrastructure installations.

[0107] Advantageously, the extracted salt can be used to make appropriate

[0108] To supply salt to soils that are rather saline. Advantageously, this can be done on September 17, 2024.

[0109] S0122 / TM: Over-salinization can be prevented through the precise monitoring of agricultural land. Furthermore, the salt can be used as a feed additive, thus promoting the growth of livestock. In particular, the salt obtained through desalination can be used as a raw material in the chemical industry for the production of chlorine and caustic soda. Finally, the salt can be used as road salt in winter to de-ice roads and sidewalks.

[0110] Another application of the recovered salt is the regeneration of ion exchangers in water softening systems, which can soften hard water.

[0111] Salt can be used as a heat storage medium. For example, excess energy from wind power can be used to heat the salt, and this heat can later be used to drive turbines. Advantageously, salt has a high heat storage capacity and can therefore store large amounts of heat over a longer period.

[0112] According to the invention, seawater is first purified and then conveyed via a pipeline to a desalination plant, where desalination takes place to a degree that enables the irrigation of agricultural land. In a further stage, the partially desalinated water can be completely desalinated so that it is suitable as drinking water for humans. Advantageously, the extracted salt can be used as an energy storage medium, allowing energy from wind or solar power plants to be used to heat the salt, which then stores the heat that can later be used, for example, to drive turbines.

[0113] According to the invention, seawater is therefore conveyed via pipelines to desalination plants, agricultural land, or human residences, after complete desalination. 17.09.2024

[0114] S0122 / TM

[0115] In an alternative embodiment of the invention, the method or device includes a sensor that determines the water content of an agricultural area and forwards this measurement value to a satellite and / or a computer for evaluation.

[0116] Advantageously, the device or method according to the invention can achieve a saving of 15 liters of diesel per hectare of agricultural land.

[0117] The device according to the invention can also include a device for taking a soil sample, wherein the soil sample is always taken from the same location by evaluating GPS data. The soil sample can be used to analyze soil quality. In an alternative embodiment, the soil sample can be sent by means of a drone. The soil sample can be examined in particular for minerals and microorganisms.

[0118] Data transmission according to the invention is wireless, and the data transmission can be carried out using radio technologies or wireless transmission methods, in particular WLAN, Bluetooth, NFC, radio optical technologies, or radio networks. Furthermore, data transmission according to the invention can be carried out via satellite, wherein data is sent to satellites or associated ground stations, or between satellites and ground stations, using radio waves or laser beams.

[0119] According to an exemplary embodiment of the invention, a method for the ecologically optimal management of agricultural land is provided, comprising:

[0120] Fertilizing and irrigating agricultural land and 17.09.2024

[0123] According to an exemplary embodiment of the invention, a method is provided comprising the steps:

[0124] Fertilizing and / or irrigating the crops of an agricultural area, specifically adapted to the respective requirements and accurate to the square meter, and if necessary individually different for each square meter.

[0125] According to an exemplary embodiment of the invention, a method is provided comprising the steps:

[0126] Partial desalination of seawater (13) by osmosis or distillation for irrigating crops.

[0127] According to an exemplary embodiment of the invention, a method is provided comprising the step of complete desalination to obtain drinking water for humans.

[0128] According to an exemplary embodiment of the invention, a method is provided wherein the salt obtained from the desalination of seawater is used as an energy storage medium.

[0129] According to an exemplary embodiment of the invention, a method is provided wherein the method for the water constitutes a closed cycle in that unused water flows back into the sea, wherein the groundwater is not included in the method and / or cycle, whereby the groundwater level is not affected by the method.

[0130] According to an exemplary embodiment of the invention, a method is provided wherein the fertilizer is part of the cycle and / or wherein the fertilizer does not enter the groundwater. 17.09.2024

[0131] S0122 / TM

[0132] According to an exemplary embodiment of the invention, a device for applying one of the methods according to the invention is provided, comprising: a nozzle for dispensing water and / or fertilizer and a means for GPS, wherein the means transmits the location and quantity of the dispensing through the nozzle to a satellite (1), wherein the means for GPS is arranged on the nozzle and / or in an agricultural area.

[0133] According to an exemplary embodiment of the invention, a device is provided comprising: a wind turbine (24) for generating electricity for a network of buildings and facilities and a device (25) for desalinating seawater by osmosis and / or distillation, wherein the wind turbine (24) transmits electrical energy that is not fed into the network to the desalination device (25) for the production of fully or partially desalinated water and salt and / or wherein the wind turbine (24) heats salt, the salt serving as a heat storage medium and / or wherein the device has a sensor in the agricultural area that transmits data on the plants and the agricultural area, in particular soil moisture, to a satellite, in particular for determining the required nutrients and irrigation.

[0134] According to an exemplary embodiment of the invention, a device is provided comprising: a solar collector (26) for generating electricity for a network of buildings and facilities from solar radiation and a device (25) for desalinating seawater by osmosis and / or distillation, wherein the solar collector (26) transfers electrical energy that is not fed into the network to the desalination device for the production of fully or partially desalinated water and salt and / or wherein the solar collector (26) heats salt, the salt serving as a heat storage medium. 17.09.2024

[0135] S0122 / TM and / or wherein the device has a sensor in the agricultural area which transmits data on the plants and the agricultural area, in particular soil moisture, to a satellite, in particular for determining the required nutrients and irrigation.

[0136] According to the invention, the collected water is first cleaned of dirt and debris. In a next step, the water is desalinated to such an extent that it is suitable for irrigating plants, especially crops. The salt obtained can be used as an energy storage medium. Energy from wind turbines, solar power, or photovoltaic systems can be used for desalination, provided there is a surplus of electricity or energy. A portion of the partially desalinated water can be completely desalinated to make it potable for human consumption. Complete desalination can also be achieved using surplus energy from wind turbines, solar power plants, and / or photovoltaic systems. The salt obtained serves as an energy storage medium. Advantageously, the rare earth elements contained in the water can also be recovered during the treatment process.

[0137] Advantageously, the inventive method does not further burden the groundwater, since only as much fertilizer is applied to the crops as they actually require. Additionally, the groundwater level is not lowered, as the water needed for irrigation is obtained by desalinating seawater. Desalination is carried out using surplus energy from wind and photovoltaic power plants when their energy or electricity cannot be used because it exceeds current demand. The salt obtained through desalination serves, in particular, as an energy storage medium.

[0138] Currently, sea levels are rising and groundwater levels are falling. The invention therefore proposes a method that uses partially desalinated seawater for irrigating agricultural land, since crops do require a certain amount of salt for irrigation. (September 17, 2024)

[0139] S0122 / TM, which are already present in seawater. For drinking water supply, the seawater is completely desalinated.

[0140] Advantageously, this process can compensate for fluctuating energy demands, even when only weather-dependent wind and solar power plants are available as energy sources. In particular, the salt already produced can be used as an energy source in the evenings when no electricity is available from solar or photovoltaic systems. Especially on weekends, when industry demands little or no energy, more salt can be produced using wind and photovoltaic power to be used as an energy source during peak demand.

[0141] The inventive method makes it possible, in particular, to transform desert regions into areas suitable for agricultural use and for the cultivation of crops.
