Posted by: Ideal for multiple-space use (sheds, tents, patios, garages, barns) Suitable for heating small spaces Light and highly portable Produces clean burning with a high energy efficiency Easy to use Simple installation process Ideal for both indoor and outdoor application CONS Not ideal for high altitude areas (beyond 7,000 feet above sea level) [10], A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. Second, converting wind or solar energy directly into heat (or mechanical energy) can be more energy efficient than when electric conversion is involved. The LO-FA was also the largest of the heat generating windmills, with a 12 meter diameter rotor. I absolutely hate the "new" math illiteracy. Subject: To build a water brake windmill from scratch. Posted by: I see a few problems with your approach. I see a few problems with your approach. The same windmill as the one pictured above, seen from below. Posted by: In total, at least a dozen different models have been documented, both DIY and commercial models. It is the calorie that is defined by the heat it takes to raise the temperature of 1 g of water 1 C. 1 cal is approximately 4.19 J and there are in fact several slightly different calories based on different definitions, see https://en.wikipedia.org/wiki/Calorie. 11 Also important is that the cost of thermal storage is 60-70% lower compared to batteries or the use of backup thermal power plants. The tower of the LO-FA windmill was filled up with 15 tonnes of water in an insulated tank: hot water could literally be tapped out of the windmill. March 12, 2019 at 11:32 AM. We are in Perth in Western Australia. I would believe 30% more efficient. Does anyone know of a source for where to buy a small permanent magnet eddy current heater for water or oil heating generation? Two ideas that might be interesting: What about adding thermoelectric generators to the set-up to generate At the time, Denmark was almost entirely dependent on imported oil for heating, which left many households in the cold when the oil supply was disturbed. But although we cannot exclude their use in pre-industrial times, the first reference to heat producing windmills dates from the 1970s, when the Danes started building them in the wake of the first oil crisis. This adds back an electric generator to the system but it only has to be sized for average power*, not peak windy day power, CrazyGadget Large Paraffin Super Warm Heater Single Burner Warmer Greenhouse Green House Plant Seeding Read Review. what it has going for it is a large volume of water in an insulated box . With it though, how would one control the temperature of the house? Happy to see an article related to my PhD research topic! September 02, 2019 at 06:36 PM. It's cheaper than my oil fired neighbours, 100% carbon free and practical for many people to install now. As for what you could actually expect from running a wind turbine directly to a room heater, the answer is: trouble. 99. Great work and service that you are providing! ", The main point was that there's no way for direct heating to be that much more efficient than using electricity as an intermediate energy form. , World Bank: Renewable electricity output. Although the Savonius is a low speed windmill which is ill-suited for electricity generation, it turns out to be an excellent producer of heat: the small windmill produced up to 1 kW of thermal power (at wind speeds of 15 m/s). February 27, 2019 at 11:45 PM. The storage system is similar to that of a concentrated solar power plant (CSP), and the solar concentrators are replaced by heat generating windmills. Different types of direct and indirect heating production compared. The windmill, which had three fiberglass blades, produced up to 8 kilowatt of heat according to non-official measurements comparable to the heat output of an electric boiler for a modest home. Because heat can be stored much more cheaply than electricity, a two-days storm can give heat for a week or longer. The idea of direct conversion of meccanical energy of a windmill into heat is so simple that it seems impossible it has not been applied on a large scale yet. It makes so much sense. Different types of direct and indirect heating production compared. I would say the biggest challenge of direct wind-powered heating system is: the utilisation of this system would be low because of the mismatch between wind power and heat demand profiles. Images from "Test at very high wind speed of a windmill controlled by a water brake", O. Helgason and A.S. Sigurdson, Science Institute, University of Iceland. Create hole for intake and exhaust hoses. Geoffrey Greene | Panels fitted to a roof can be neat and unobtrusive, unlike the more obvious presence of a wind turbine. The study referenced in note 15 contradicts your claims. How would it be easily replicable? A gear box could switch between heating and cooling modes. Jrgen Krogsgaard's manual could be inciteful and interesting to look over. That's also an interesting idea, and it could be more practical than what Job proposes. Theres two reasons for this. Kris De Decker | Third, you lose a significant cost advantage because you reintroduce all the electric components. Good question. A mechanical heat pump is simply a heat pump without the electric motor instead, the wind rotor is directly connected to the compressor(s) of the heat pump. 7. Direct heat production thus offers the possibility to save three times more greenhouse gas emissions and fossil fuels using the same number of windmills, which are also cheaper and more sustainable to build. The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. To work out the power rating of your inverter, simply add up the required wattage of all the equipment you'll be using. In a 2011 paper, German and UK scientists write that small and remote households in northern regions demand thermal energy rather than electricity, and therefore wind turbines in such places should be build for thermal energy generation. 2 If we only look at households, thermal energy for space and water heating in temperate and cold climates can be 60-80% of total domestic energy demand. It features 1260Wh of capacity, enough to run power tools, including a circular saw, electric hammer drill, or bench grinder. Again, also here things dont change much from the conventional. As the stirring rods are lowered into the BBs, the resistance rises very quickly. July 17, 2020 at 06:37 AM. This is comparable to the heat output of the smallest electric boilers for space heating. Posted by: Positioned between the power source and the battery, a charge controller stops your battery over-charging by regulating the amount of power channelled to it. Could this heat storage via water tank double as a way to store potable water? 7, Interest in heat generating windmills resurfaced a few years ago, although for now it concerns only a handful of scientific studies. I corrected the sentence, thanks for pointing it out. Due to friction among molecules of the water, mechanical energy is converted into heat energy. I'm very curious to read those results, but you did not provide the link you are talking about Hi Kris - oh shoot - so sorry. March 09, 2019 at 11:46 PM. Hugh Conway | Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system. [8] A 2013 study using a prototype obtained similar results, and calculated the efficiency of the system to be 91%. Source: 7, Providing enough storage to bridge a week without wind thus requires up to 7 tonnes of water, which corresponds to a volume of 7 cubic meters plus insulation. I think this technology could be great for island communities in higher latitudes. The heat medium would be work done inside the house by the electricity. According toWhich, while micro roof-mounted wind turbines are cheaper, theyre also less efficient and will produce a lot less electricity than pole-mounted ones. The windmill, which had three fiberglass blades, produced up to 8 kilowatt of heat according to non-official measurements comparable to the heat output of an electric boiler for a modest home. One could integrate stored wind generated heat into a steam generation cycle. @Kris I'm not seeing the contradiction in [15]. this would not matter so much in this context as the unutilized heat Very interesting article! We looked carefully at direct water heating via the actual PV panels and found there are two manufacturers (one French and the other Turkish) but they only seem to be effective at lower temperatures such as pool heating plus we have long very hot summers and solar water heaters tend to spend summers venting hot water to avoid overheating in any case. 14. One option is to use source heat that does not have to be maintained and a storage tank. Source: [7]. Your comment could not be posted. The Wind Heater by Korean designer Jihae Kim presents a sustainable technological heating solution during harsh winters. Taking your shed off-grid is simple to achieve, good for the environment, and could save money in the long-term. Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. If driven by a windmill, such as my Sharp Cycloturbine, good load matching should be possible. Local heating can also be combined with direct heat production, and then you win even more. Almost nobody knows that a windmill can produce heat directly. For example, a 5W mobile phone charger will require an inverter with a continuous power rating of at least 150W, whereas a 400W desktop computer would require at least 600W. Does anyone have one for purchase and test? , themes: Off-the-grid energy storage Heating and cooling Wind power Renewable energy History. joseph | For a ground source domestic heat pump, that is typically 4 times more heat energy out than electrical energy in. A mechanical windmill can also be coupled to a mechanical heat pump, which can be cheaper than using a gas boiler or an electric heat pump driven by a wind turbine. The convolutions used (and I'm only guessing here) is that 70% efficiency means 30% loss, and that 90% efficient means 10% loss, so 1/3 the loss is the same as a 3x gain. Erik | Great work and service that you are providing! Do you just need a couple of lights for occasional use, or do you plan to run broadband, a computer, heating, or a host of power tools? Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. I would love to learn more about the feasibility of those mills as heating system for small houses. I am willing and available although I'm not sure of the best way to coordinate such a workgroup. If you want to see the little relay the following link will take you there. 7. For even larger systems, energy needs to be transported in the form of electricity, and in that case direct generation of heat with all its benefits becomes unattractive. If there are no commercial units of small permanent magnet eddy current heaters for water or oil heating generation currently available, maybe one or more of "us" Low-tech Magazine readers has the capabilities to build one? Posted by: Check Price 15% OFF. Well, there is a great problem in that an average wind speed of 11 mps is rare.that is nearly 25mph. Energy 164 (2018): 925-936. Not very elegant but it works for us. It is the calorie that is defined by the heat it takes to raise the temperature of 1 g of water 1 C. 1 cal is approximately 4.19 J and there are in fact several slightly different calories based on different definitions, see https://en.wikipedia.org/wiki/Calorie. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. The scientists calculate that the maximum distance that is cost-achievable under optimal wind conditions is 50 km. They are quite inefficient but Would the amount of water in radiators be reduced or increased based on how hot or cool you'd want? It transferred the rotational energy from its wind rotor directly to the axis of a machine, for example for sawing wood or grinding grain. I would believe 30% more efficient. Arturs | Interesting to see in this case how industrially manufactured systems for energy generation and conversion are oriented so much around the "generally accepted" energy transfer media (mostly electricity of course) that it becomes rather hard for DIYers to get started. In particular, the electric heat pump is promoted by many governments and organisations as a sustainable solution for renewable heat generation. Another model could be to run an air compressor from the turbine. Or some pointers on the formulas to figure this out ourselves? If oil or pressurised water could be used as the brake fluid, then much higher temperatures could be achieved. steve | March 01, 2019 at 07:46 PM. You feed that to a 500 Watt heater. Directly coupling a mechanical windmill to a mechanical heat pump is cheaper than using a gas boiler or the combination of a wind turbine and an electric heat pump. plugged into these to make them greener. Given this, there is far more value in driving a heat pump rather than directly converting the mechanical energy to heat. Photo by Claus Nybroe. 2. What if We Replace Guns and Bullets with Bows and Arrows? How to design a sailing ship for the 21st century? Image: prototypes of heat generating windmills, built by Esra L. Sorensen in 1974. In terms of using wind-driven mechanical heat pumps to produce heat. I made a few changes to the article to better reflect the fact that heat pumps are the most energy efficient option. For example in the UK, heat counts for almost half of total energy use. Image provided by the Nordic Folkecenter in Denmark. February 28, 2019 at 09:36 PM. steve | Could be a topic for a future article. fake by any means necessary jacket. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). September 28, 2020 at 10:19 PM. In case someone might be interested, there is a UK-based company called "H2O Turbine", and they have wind turbines using water breaks to produce hot. Peter Sharp | Press the space key then arrow keys to make a selection. Read Low-tech Magazine with no access to a computer, a power supply, or the internet. First, thank you for putting up such an interesting web site. These are comprised of a magnet mounted on a rotating shaft, and can reach temperatures of up to 600 degrees Celsius. Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. BEST FOR GABLE ROOF: Ventamatic 1600 CFM Mill . Posted by: I'm very curious to read those results, but you did not provide the link you are talking about Posted by: Maybe a storage system with both hot and cold stores might be interesting. 2. We are designing the device specifically for the needs of Newfoundlander and for that we want your input. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). However, in the LO-FA windmill all mechanical parts for energy conversion were moved to the top of the tower. I did not look into wind powered cooling but it could be possible. Not sure about your approach though. HeadakusMaximus | Join our email club Logan | Windmills have braking systems that can stop them from turning when you dont need their energy to impute. I would be interested if a mechanical windmill could be coupled with cryogenic energy storage. [13]. 1. Publicat de Universitatea Tehnic Gheorghe Asachi din Iai Tomul LIX (LXIII), Fasc. The average wind speed is not guaranteed either, which means that a heat generating windmill requires heat storage otherwise it would only provide heating when the wind blows. [1] [15] In this second type of heat generating windmill, heat is produced with with mechanical heat pumps or hydrodynamic retarders, not with a water brake. Update to my comment above: here's an Island household in Denmark where the owners have posted comparative practical results of the Calorius 37 windmill with solar thermal collectors. They are in their seventies and eighties now, some of them have passed away. Update to my comment above: here's an Island household in Denmark where the owners have posted comparative practical results of the Calorius 37 windmill with solar thermal collectors. Does anyone have a step-by-step instruction of how to build one that is functional in "actual size", not just a model for display? For example, a wind turbine converts its rotational energy into electricity by the use of its electrical generator, and this electricity can then be converted into heat using an electric heater, an electric boiler, or an electric heat pump. Urban Fish Ponds: Low-tech Sewage Treatment for Towns and Cities. 1 15 In this second type of heat generating windmill, heat is produced with mechanical heat pumps or hydrodynamic retarders, not with a water brake. "Usage of the Wind Energy for Heating of the Energy-Efficient Buildings: Analysis of Possibilities." 5 6. In the meantime, if anyone else has more info, feel free to share it. The trick here is to turn the lower heating element to a much higher setting than you would the upper heating element. , Integration of Thermal Energy Storage into Energy Network, Sharyar Ahmed, 2017, The bright future of solar thermal powered factories, Kris De Decker, Low-tech Magazine, 2011, Solar Heat Worldwide, edition 2018, International Energy Agency (IEA). Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. The Danish water brake windmill from the 1970s was a relatively small machine, with a rotor diameter of around 6 meters and a height of around 12 meters. But if you want AC power for tools or charging batteries, you'll need to spend more than $3,000 for a high-end system. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. Furthermore, direct heat generation greatly improves the economics and the sustainability of smaller types of windmills. For a ground source domestic heat pump, that is typically 4 times more heat energy out than electrical energy in. February 28, 2019 at 12:49 AM. The heated water can be pumped into a building for heating or washing, and the same concept could be applied to industrial processes in a factory that require relatively low temperatures. Maybe a storage system with both hot and cold stores might be interesting. That and a 5 meter (16+ ft) diameter rotor You will have a difficult time finding a location that reliably supplies the required wind speed and has space for a largish (and noisy) turbine. A gear box could switch between heating and cooling modes. Any thoughts? Kris De Decker It compares these four technologies for three system sizes: a small windmill aimed at heating an off-the-grid household, a large windmill aimed at supplying heat to a village, and a wind farm producing heat for 20,000 inhabitants. Also on a larger scale, I think it makes more sense to have heat generating and electricity generating windmills standing alongside each other, rather than combining them into one machine. The powerful battery fueled Mr. Heater Hero offers 35,000 BTU, heating up to 850 square feet of space. Once you have captured the energy from the sun or wind, you need to store it for later use by feeding it into a deep cycle battery or a deep discharge battery. Posted by: Compression will give you a heater, and then releasing the compressed air will give you cooling. [14]. Consequently, the heat generating windmill is at its best as a decentralised energy source, providing heat to an off-the-grid household or in the optimal case a relatively small town or city, or an industrial area. Furthermore, the friction liquid in the water brake was not water but hydraulic oil, which can be heated up to much higher temperatures. So I experimented a bit toward creating more concentrated heat at a high temperature. Of cause it is not economical to have that much storage. March 01, 2019 at 10:10 PM. How to Build a Practical Household Bike Generator, The Printed Website: Volume III & The Comments. And there's also hot water production for washing and cleaning. If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. If you also want renewable electricity, you could use solar PV or a second windmill instead of trying to fit everything into one machine. Posted by: I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) And there's also hot water production for washing and cleaning. Main Fair points. 3) Coal bed fire pit. Furthermore, direct heat generation greatly improves the economics and the sustainability of smaller types of windmills. I went looking for a source for eddy current heaters, however, and came up with nothing. However, energy losses (self-discharge) should also be taken into account, and this explains why the Danish heat generating windmills usually had a storage tank holding ten to twenty thousand liters of water. However, in this case a gearbox is required to achieve optimal efficiency. This involves one less energy conversion, which makes the combination at least 10% more energy efficient than an electric heat pump driven by a wind turbine. I absolutely hate the "new" math illiteracy. BEST SOLAR VENT: Master Flow 500 CFM Solar Powered Roof Mount Exhaust. Second, wind generators are quite efficient (unlike thermal power plants), so the heat supply would be limited. However, energy losses (self-discharge) should also be taken into account, and this explains why the Danish heat generating windmills usually had a storage tank holding ten to twenty thousand liters of water. Because heat can be stored much more cheaply than electricity, a two-days storm can give heat for a week or longer. Mario Stoltz | SHOP OUR RANGE OF MODULAR SHEDS NOW. Posted by: steve | February 28, 2019 at 12:36 AM. The system is functionally designed to create and retain heat so would need quite a few modifications to also act as a cooler. If you had any pointers to resources, links to other people's DIY direct wind-to-heat pump setups, or were planning on doing an article on those, that would be greatly appreciated! to receive exclusive offers and discounts. the generator is not up on the tower (requiring a stronger tower). Posted by: [16] In these systems, the generated heat is converted to electricity by the use of a steam turbine. . Of course, there are other ways but this is the simplest solution. Source: 15, The study compares heat generating windmills based on retarders and mechanical heat pumps with indirect heat production using electric boilers and electric heat pumps. Posted by: What steam turbine? A heat generating windmill can also be combined with a solar boiler, so that both sun and wind can supply direct thermal energy using the same heat storage reservoir. The direct approach to heat production is considerably cheaper and more sustainable than converting wind or solar generated electricity into heat by using electric heating devices. You can install a bank of more than one battery to increase the available power store. Posted by: If you follow that approach, you win indeed. The heater requires a specific battery or electricity to ignite the propane and run the fans that blow out the hot air. Journal of Sustainable Architecture and Civil Engineering 10.1 (2015): 58-65. These panels can be sited either on the ground nearby, or on the shed roof itself. How efficient is mechanical transmission of energy? Show sites now open. The main exception is the traditional use of biomass for cooking and heating but in the developed world even biomass is often used to produce electricity instead of heat. Obviously, its not always stormy weather, which means that the average wind speed is at least as important. The most recent and extensive studies to date are from 2016 and 2018, and compare different types of heat generating windmills with different types of indirect heat generation. Although the Savonius is a low speed windmill which is ill-suited for electricity generation, it turns out to be an excellent producer of heat: the small windmill produced up to 1 kW of thermal power (at wind speeds of 15 m/s). Installing a 20,000L tank is a significant expense, but might be worth it in areas with intermittent access to water or drought conditions. The hydrodynamic retarder is well known as a brake system in heavy vehicles. Could be a good opportunity for a smaller manufacturer, though starting a company around this is probably not so straightforward - there must have been a reason why Westrup in Denmark is no longer around. It would need off the shelf part preferably OpenSource (cost wise it would be better to pay someone most in need to design for instance in Bangladesh with a low fee cryptocurrency to design it). Instead of having the turbine use the water as a break, you could use the turbine to pump the water through a cooling track and suck the heat out of the house.
