A^system^and^method^for^generating^and^storing^energy^from^w ind Technical^field The invention belongs to the field of power generation, particularly to the field of using wind to generate electricity. Technical^background Using wind to generate useful work is an old idea, much older than electricity. With the rise of electrical power, much thought has been put into using wind to generate electrical power with mixed success. There are fundamental problems. Natural winds occur irregularly, with varying strength, from varying directions and does so in a way that is difficult to predict with any accuracy for more than a few hours or days. Generally, days with much wind do not coincide with days with much demand for electricity. Furthermore, a major wind plant is generally considered an undesirable thing to have in one’s neighborhood due to noise and other considerations. They also kill birds. One way around some of these problems is to have the wind plants in naturally wind places, such as at sea. That, however, adds to the cost of the construction of wind plants. Maintenance also becomes more difficult. Also, the electricity must be transported a long way adding the cost and maintenance of long cables. Many of these problems can be avoided by not relying on naturally occurring wind, but instead take advantage of the draft of cars passing through, preferably through a tunnel. Traffic through a tunnel varies, but compared to wind, it is more regular and predictable. People do not live in traffic tunnels so there are no neighbors that will be bothered by the plant, and it probably makes less noise than the traffic anyway. Traffic tunnels and other high traffic roads are typically located near or in high-population areas, so the electricity does not need to be transported far. A high traffic road is also an accessible place, reducing the cost of construction and maintenance. However, some problems remain. Intense traffic generally do not coincide with high demand for electric power. Quite the contrary, when people are in their cars they are off the electrical grid and cannot consume the electricity from the electrical grid. What is needed is a solution that allows harvesting the wind energy created by passing cars in combination with some sort of practical way of storing the energy in some form and send it off to the grid in the form of electrical energy at a later time, perhaps a few hours later. This storage method should be of moderate cost and maintenance, be environmentally friendly -both in the global sense but also in the sense that it does not make the local environment unpleasant- and generally be more practical and economical than, say, a huge stack of batteries. US9212653 is an apparatus for generating power from a wind to power propeller driven turbine at for instance an airport runway and has power generator actuated in response to wind from vehicle such as aircraft. This actuates a hydraulic cylinder which pumps and store hydraulic fluid under pressure in an accumulator reservoir. There is nothing in this invention about storing the harvested energy until it is needed. While the patent does mention “storing” it is in a different sense. As it says in [0020] “the quantity of hydraulic fluid is released to power the hydraulic electrical generator when an optimum pressure level is achieved” id est the storing is for optimal efficiency of the device not for energy storing purposes in the context of the invention at hand -that is for hours or days. US7964984 is a power generating system for remove monitoring such as a weather monitoring system. The purpose of the system is thus not to generate electricity for use in the electrical grid but self-electricity generation. The patent does disclose a system using intermittent wind from passing traffic to acuate a reciprocating device. It says in [0009] “The system includes a power generating apparatus carried by the frame and adapted to actuate when the panel reciprocates such that power is generated for use by a power consuming, power storing, or power transmitting device.” but no power storage device is described except that batteries is mentioned as a possibility in [0038]. WO2014094680 is also a power generating system addressing the problem with generating power for a device, in particular a lamp, not for power generation for the grid. This patent discloses a system for utilizing wind from passing trains and it does also disclose a system for storing energy for use in lamps first as mechanical energy in a flywheel, then as electrical energy in batteries. It does not feature an energy storage system in the context of the invention at hand. WO2014094672 is a power generation device for power production, not for use in a specific device. It uses suction from a high-speed train to actuate a reciprocating panel causing a liquid to be paused through a hydraulic motor that drives an electricity generator. However, there is no means for storing energy in the context of the invention at hand. CN202645863U is a Chinese utility model describing of using wind from passing vehicles to actuate an aerofoil in a reciprocating motion which is then turned into a rotary motion which is used to generate electricity. No system for storage of energy is mentioned. CN207145144U is another Chinese utility model. It describes a system for electricity harvesting, storage and generation. It is a wind turbine causing a piston pump to pump water into a storage tower. The water can later be turned into electricity. However, the system uses natural wind and a turbine, not an actuating device and wind from passing vehicles. CN212155070U is yet another Chinese utility model. It describes a water lifting device driven by wind. However, there it is not driven by the wind from passing vehicles but by natural wind. WO2020187211 is a water pumping device using a windmill to drive a piston assembly to pump gas or liquid. It is not intended for generating electricity and it uses a windmill with natural energy, not a reciprocating device driven by passing vehicles. None of these would inventions fulfills the need for a solution that allows harvesting the wind energy created by passing cars in combination with some sort of practical, convenient and relatively inexpensive way of storing the energy in some form, and send it off to the grid in the form of electrical energy at a later time Summary^of^the^invention A solution to this problem is to capture the wind created by passing vehicles with one or more single, separate sail, board or blades. This gives rise to a reciprocating motion in the one or more single separate sail, board or blade. This actuating motion is used for actuating one or more pumps (4) that pumps a fluid against gravity into an upper reservoir. This generates potential energy. The potential energy of the water can, immediately or at a later time, be released by letting the fluid flow back by gravity into a lower reservoir. The flow can then be used to drive one or more turbines to generate electrical power. Advantages with this solution includes: Compared with conventional wind turbines, this source of wind is reliable and predictable. Unlike a conventional wind turbine, it works when there is little natural wind and it works when there is much natural wind (a conventional wind turbine needs to be turned off at around 22 m/s or more wind). Also, the lack of dependence on natural wind means that it does not need to be placed in a windy location. Such locations are often difficult to reach -such as on heights or at sea. This invention works best in accessible places with plenty of traffic. The ease of access translate into lower cost and lower environmental impact of construction installment and maintenance. Maintenance of a single 2-4MW wind turbine costs 42,000-48,000 $ a year according to various data published online on wind turbines. Also, the sheer height of a conventional turbine in an of itself is a problem and a danger. The current invention can be made much closer to the ground. This invention is, unlike a conventional wind turbine, not likely to cause damage to or kill birds, being placed where it is much traffic and not moving as fast or with as much force as the blades of a conventional wind turbine. The energy storage system can be made with environmentally friendly material, particularly in comparison with a large battery park. The storage system can store energy for a long time with little loss. There might be some loss due to evaporation if water is stored, but that might be compensated by rain and snow. Water pumping can be done over long distances (turbines and fluid pumping can also be at considerable heights with each other) avoiding the transmission network as it has high construction and maintenance costs, poses a risk to the health of living world and the area under the network and around it becomes almost impossible to use. Due to moderate initial investment and low maintenance compared to wind and solar power, return on investment is expected to be faster on the current invention. The system of the invention is more reliable and generates electricity in roughly equal amounts in every season. This is advantageous compared to solar energy in a temperate to cold climate where the solar energy is mostly created in the summer while energy is mostly needed in the winter for heating. The space immediately close to a road is generally not a desirable space to be or live, so unlike wind or solar power, it does not take up a space desirable for living, recreation, agriculture or other purpose. Unlike conventional wind turbines, the system of the invention is not likely to be struck by lightning. The invention can have the turbine and other electricity generating gear places far from other parts, increasing fire safety. Existing natural lakes can also be used for reservoirs for the system of this invention. In regions where temperatures are often low temperatures, anti-freeze additives can be used and some of the equipment can be installed underground or insulated against freezing. Brief^description^of^the^drawings Fig 1 shows a schematic view of the wind from passing traffic being harvested for storage in an upper reservoir. Fig 2 shows a schematic but more detailed view of how the actuating motion is made to pump water that can be used for electricity production. Fig 3 shows an example of how the board, blade or sail that captures the wind of a passing vehicle and turns it into a reciprocating motion can look like. It is the same board, blade or sail as in Fig 2. Detailed^description Legend for the figs: 1: the system, the invention as a whole 2: passing vehicles that give rise to wind 3: single separate sail, board or blade (3) (as opposed to multiple blades in a propeller or turbine) in a reciprocating motion 4: pump to pump fluid 5: lower reservoir to store fluid 6: upper reservoir to store fluid and potential energy 7: turbine to generate electrical power In fig. 1 we see a schematic view of how the boards or sails hang from above, one sail placed directly vehicles and one to the side. They move by the draft of passing vehicles. The sail should be placed as close as possible to the movement of vehicles in both these sails (as close as the traffic safety and traffic norms allow that is). The width of the sail, board or blade should be about 2.5-3m approximately the width of the road, but it is better determined by the aerodynamics experts, should be built so as not to obstruct the other lane of traffic movement in the same or opposite direction, in a word we can say: the force of air during the movement of vehicles hitting the sail must always be greater than the friction that occurs with the air in the rest behind the sail. The distance should be sufficient between the sails to not hinder the mutual movement between them. The height of the sail should be installed where the wind power from the vehicles hits more and its dimensions should be suitable with the area where the wind from the vehicles hits hard. Even for the sail on the side of the road, it more captures the power of winds from small vehicles (if placed in the lane for fast movement of small vehicles, small vehicles are less efficient in the high sail due to distance), while large vehicles can hit almost on both sails but not simultaneously, the sails should not be placed on the same axle, only if the distance of the vehicle from the sail up and to the side is the same, e.g. as in the train. The pump is this embodiment can be a piston pump. In this embodiment can also operate with a small load enough to beat the internal piston to rub against its cylinder by calculating the water pressure (gravity allows the sail to return to a vertical position after hit) but the inlet-outlet connection of the fluid must be changed, the load material can be made from the recycling of heavy metals, batteries out of use or recycled if they do not cause pollution, concrete etc. Water pipes can be made of recycled plastic if they can withstand high pressures. The load should be semi-oval in shape at the top. In fig.2 we have presented a sail, but it can also be a board or slab of lightweight material, alloy or plastic, wrapped in a windproof material or similar material. This construction is mechanically connected to the shaft which moves in bearings, makes reciprocal movements and on the other hand makes it possible to pull the metal ropes back and forth by pulling a certain load in the opposite direction of gravity for pumping fluid. In fig.2, if construction conditions allow, loads and pistons can be installed under objects, for example: if we have to install 5 pistons on both sides of the object (10 pistons), if we have space under the object, we can install only 5 of them, ie 50% less pistons and the load in this form reduces the investment cost. If a sail that has 2 or more pillars raised high and has a large width can be placed on 2 or more axes in the same direction, the width and height of the sail should be as large as possible. The surface of contact with the wind should be as large as possible and its shape should be such that they have the greatest possible friction with the wind. In order to capture as much wind as possible, sails should be built as large as possible both in height, but also have as much surface area between the two single pillars in fig 2’ i.e. as much width as possible. Materials used should be as light as possible, for the pillars materials such as carbon fiber might be useful. The area between the pillars that might be textile (possibly even recycled). It is important that it is impermeable to air. The possibility of capturing the direction of the wind should be considered if the technical conditions allow. To keep weight down the materials should be as thin as possible without making the construction to fragile and susceptible to wear and tear. We can imagine placing the sail in fig 2 on a pivotable axle to allow the sail to turn to capture wind from different directions. In many ways a tunnel is the most suitable place to install the system but we can easily imagine other places. A regular road, road without a tunnel is an obvious alternative. This system can probably be installed on large ferries (for the ferry’s needs), we always have water, maybe even strong winds, it can be installed under bridges. An important aspect of fig 2 is when it is installed in a region with turbulent winds above 80km / h or we should try to capture continuous winds at high altitudes in each region. According to the scheme we have presented, the boards make reciprocal movements even if the wind speed is low. The movement must be done at a certain angle so that the load allows us to turn the blade to its previous position, the vertical position and in this position the wind hits the board with greater force. The amount of fluid that rises and at what height, depends on several factors: ^ Wind speed, ^ The lightest weight of the blade but resistant to wind blows, ^ As large as possible blade surface in contact with air, ^ The ratio between the height of the board and the short arm under the shaft to which the ropes are tied, ^ The volume of the piston and its shape (the longer the piston the more efficient it is because the same load is used to pump larger amounts of fluid) etc. Such facilities are easy to build, have low cost and also for the construction of such a facility by recyclable materials which can be used in those parts where possible. Natural lakes can be used to store water (potential energy) for exploitation as needed, the invention works with the same amount of water and can also use rainwater or wastewater after treatment in the respective plants. The system can also be integrated with one or more electricity driven apparatuses such as apparatuses useful in a road tunnel. This could be night lights, emergency lights, data sharing beacons part of a mesh network, emergency signal beacons, commercial displays with lightning, C0 ₂ removers, air cleaners, wild life detergent (such as speakers), specifically bird detergents. The term “fluid” used in the claims refers to a substance that flows, that is a liquid or a gas. Water is the obvious choice of fluid, being cheap and easily available. Other fluids are possible though, and might be advantageous, particularly in a system where fluid loss is small. A heavier fluid allows for more storage of energy. A fluid with lower freezing point removes or reduces the problem with water freezing at low temperatures. Even if water is used, it should not be assumed this is water only. Additives might be useful such as anti- freeze to prevent freezing below zero degrees Celsius. As mentioned, with this idea you can pump all the substances that pass into the piston maybe even a gas such as air, though that is probably not practical except in special circumstances. One such special situation might be from a region with strong winds or usually the coast in a region with less wind to the reservoir below the turbine, then with the help of a device that makes it possible under air pressure to raise water up and store it as potential energy (air can not be saved if we do not turn it into potential water energy). The reason is that if it is a large amount of water that we have used for energy production, it has a cost to return to the place where it is pumped (if it is high distance) only if combined with a river, sea or something else, but pumping air at short distances is not worth implementing. The phrase “single separate” such as in “single, separate sail, board or blade” should be interpreted as opposed to several blades in a turbine or propeller. It should not be interpreted to mean that there can only be one sail, board or blade. Nor should it be interpreted as sails, board or blades being completely physically separated (e.g. in separate rooms or very far apart). The phrase “pumps a fluid against gravity generating potential energy” used in claim 1 should not be interpreted as the fluid only moving in the upward (against gravity) direction. The phrase “immediately or at a later time allow the fluid to flow from the upper reservoir by gravity” together with the phrase “driven to generate electrical power by the flow of the fluid when the fluid flows by gravity from the upper reservoir (6) to the lower reservoir (5)” in claim 1 should be interpreted as there is a choice between generating electricity now or at a later time. This is an important feature of the invention, the ability to generate electricity at a later time when it is needed. The choice is, of course, subject to practical limitations. If the upper reservoir is full there might be a “use it or lose it” situation. Furthermore the “choice” is not necessarily made directly by a human, and it is usually preferable with some sort of automatic system. The phrase “essentially water” used in claim 3 means it is mostly water but probably not 100% pure. The water might contain some additive like anti-freeze and non-deliberate impurities might also occur.
