Davide Honey | 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. This adds back an electric generator to the system but it only has to be sized for average power*, not peak windy day power, Posted by: > Also, how would you transfer the waste heat from the generator to the heat medium? 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. Furthermore, direct heat generation greatly improves the economics and the sustainability of smaller types of windmills. CrazyGadget Large Paraffin Super Warm Heater Single Burner Warmer Greenhouse Green House Plant Seeding Read Review. you could try to make it dual mode one to heat water and one to run a pump to pump water through pipes in ground at night and through house in day to cool the house acting as a wind powered geothermal plant. To use a heat pump and avoid using grid power we would have needed quite a large PV array or we would have had to operate it from our battery which would reduce our overnight reserve power. 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. "WIND POWERED THERMAL ENERGY SYSTEMS (WTES)". I'm not a native English speaker and I should have written "as efficient". Midsummer Energysupplies a range of kits for solar power, whileWind & Sunhas some good offerings for wind power. So I experimented a bit toward creating more concentrated heat at a high temperature. Most used simple wooden blades. In terms of using wind-driven mechanical heat pumps to produce heat. 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). The hydrodynamic retarder is well known as a brake system in heavy vehicles. I have no commercial relationship with them other than as a customer. March 01, 2019 at 06:23 PM. The study referenced in note 15 contradicts your claims. 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! A UK based solar system could suffer from a lack of available sunshine, particularly in the winter months. This results seems to be excessive compared to the other heat generating windmills, but the energy output of a windmill increases more than proportionally with the rotor diameter and the wind speed. I built a water brake using a paint can and spun it with my drill press. Tests have shown that small wind turbines producing electricity are very inefficient and dont always generate as much energy as was needed to produce them. 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. Overload your circuit and it will overheat and could catch fire; go for too high a rating and youre just wasting money. HeadakusMaximus | Due to friction among molecules of the water, mechanical energy is converted into heat energy. March 01, 2019 at 09:19 PM, > The conclusion says that coupling a wind turbine to a heat pump is the most cost effective realization of wind powered heating. And more efficient. 3. Posted by: , Real-world tests of small wind turbines in Netherlands and the UK, Kris De Decker, The Oil Drum, 2010. 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. Your comment has not yet been posted. It would suck in cold air from the rest of the room, and dump its waste heat under the desk, turning into a "free" foot heater. For example, for the very small Savonius windmill that the scientists used as a model (0.5m rotor diameter, 2m tower), it was calculated that the impeller diameter should be 0.388m. 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. What do you think? Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. However, in the LO-FA windmill all mechanical parts for energy conversion were moved to the top of the tower. Obviously not everyone has space for a heat generating windmill, but there's no need to put a windmill next to each house. The result is heat generated by wind energy. Great article. If more information is needed maybe we could pool our resources and help one another to gather information for a Proto build. Great work and service that you are providing! Nitto, Dipl-Ing Alejandro Nicols, Carsten Agert, and Yvonne Scholz. Photo by Ricard Matzen. February 28, 2019 at 12:36 AM. Registered Address: Old Great North Road, Sutton-on-Trent, Nottinghamshire, NG23 6QN. Thanks for your speedy reply. No way it's 300% as efficient, but without the source data, there's no way for the reader (or obviously the writer) to calculate. Too much cheap energy from the fossil fuel for too many years has turned us unable to see these kind of solutions. There is much more to win on the demand side than on the supply side, and the habit to heat the whole space of a building can indeed be questioned. Source: 7. February 28, 2019 at 11:44 AM. Happy to see an article related to my PhD research topic! I changed it into "more efficient". [7], Interest in heat generating windmills resurfaced a few years ago, although for now it concerns only a handful of scientific studies. This prevents automated programs from posting comments. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). Posted by: Still, thanks for expanding our horizon of the possible! Dimitar Bounov | The heat medium would be work done inside the house by the electricity. If you can afford it, a combination of both wind and solar power gives you the best of both worlds. Generate storable heat during off-peak hours. If your turbine is positioned in the right location, a large amount of electricity can be generated quickly. Third, you lose a significant cost advantage because you reintroduce all the electric components. The " how to keep a shed warm without electricity " is a guide that tells users how they can heat their sheds without using electricity. If in doubt, contact them directly for advice. 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. February 28, 2019 at 02:39 PM. It's mechanical windmills with mechanical heat pumps that are more energy efficient (and cheaper) than wind turbines with electrical heat pumps. ben.ben0911@gmail.com, Posted by: Posted by: A Calorius windmill producing up to 4 kW of heat. Lava Heat Italia CAPRI-A-LINE-6MPB Propane Heater$1,010. [8]. Obviously, its not always stormy weather, which means that the average wind speed is at least as important. Propane Heater, thermomate 18,000 BTU Portable LP Gas Heater with 3 Power Settings, Mobile Radiant Cabinet LP Heater with Gas Regulator and Hose, Heating Area Up to 450 Sq. Posted by: In a water brake windmill, electric generator, power converters, transformer and gearbox can be excluded, and because of the weight savings, the windmill needs to be less sturdy built. Essentially one of these: https://en.wikipedia.org/wiki/Heat_pump_and_refrigeration_cycle#Gas_cycle - they're not technically as efficient as a phase change, but if it's simpler and there are fewer moving parts, it might be a win. BVG Group Ltd. Walton Web Limited is acting as a credit broker offering finance products from Omni Capital Retail Finance Limited. It's probably going to be less practical compared to using a water brake. In the same way that solar-generated electricity is reduced in wintertime, during the summer, lighter winds can limit the amount of power available from wind turbines. Also great for even, oscillating heat . Much less known is that a mechanical windmill can do the same in a windy climate -- by oversizing its brake system, a windmill can generate lots of direct heat through friction. Free delivery to most postcodes. , SMALL WIND ENERGY SYSTEM WITH PERMANENT MAGNET EDDY CURRENT HEATER, BY ION SOBOR, VASILE RACHIER, ANDREI CHICIUC and RODION CIUPERC. Intresting article for sure! I went looking for a source for eddy current heaters, however, and came up with nothing. View an alternate. Toby | 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. Keeping Some of the Lights On: Redefining Energy Security | Hugh Conway | Comments are moderated and will not appear until approved by the author. Chuck Hays | A 2015 study investigates the possibilities of heat generating windmills in Lithuania, a Baltic country with a cold climate thats dependent on expensive fuel imports. I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) I would love to learn more about the feasibility of those mills as heating system for small houses. February 27, 2019 at 11:45 PM. A division of Updated On Feb 2023 2,142 Reviews Studied By Customer Ratings Affiliate Disclosure 1 PK Green Solar Fan 12V 20W | Portable Solar Fan Kit for Car, Caravan, Greenhouse, Shed, Motorhome | Small DC Fan Ventila. | Low-tech Magazine: The Printed Website . So I experimented a bit toward creating more concentrated heat at a high temperature. The result is heat generated by wind energy. 15. The writer of the book chapter may know, but he didn't answer my questions. I'll post their reply (if it comes) here in the comments section. How would the economics or environmental considerations be affected if you were to move a lightweight windmill during the course of the year, in order to have windmill spend most of its time where the wind is blowing or the climate is cold? Walton Web Ltd 2019. what it has going for it is a large volume of water in an insulated box . https://www.highviewpower.com/technology/. [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. "Usage of the Wind Energy for Heating of the Energy-Efficient Buildings: Analysis of Possibilities." Sorry for the silly question! The four heating concepts are ranked based on their yearly capital and operational expenditures, assuming a lifespan of 20 years. ", 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. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. [14]. I'll keep you updated here in the comments section. They are quite inefficient but this would not matter so much in this context as the unutilized heat would go towards the primary goal of heating an inhabited room. Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heating system. Job van der Zwan | Final Words. For example how much more heat do you get when you use ground loops or ground water vs outside air? Posted by: The plan is for a passive heater made with soda cans, an old window, and some insulation. While renewable energy sources account for more than 20% of global electricity demand (mostly hydroelectric), they only account for 10% of global heat demand (mostly biomass). Pro Breeze. ", (note: 3x AS efficient is not the same as 3x MORE efficient). A gear box would help, but this adds complexity. Source: 8. This is saying that direct wind to heat would then be 280% efficient. "Expanding the horizons of power-to-heat: Cost assessment for new space heating concepts with Wind Powered Thermal Energy Systems." Mario Stoltz | [13]. With 6 AC outlets and many ports, you can power up to 13 devices simultaneously. There was also a "LO-RA" water brake mill. It would suck in cold air from the rest of the room, and dump its waste heat under the desk, turning into a "free" foot heater. 9 This is comparable to the efficiency of a wind turbine heating water through electricity. I corrected the sentence, thanks for pointing it out. Some low-tech cooling approaches, and "just get used to the summer heat", fall short, but a mechanical-input heat pump could also be a dehumidifier. If oil or pressurised water could be used as the brake fluid, then much higher temperatures could be achieved. Ideas anyone? Furthermore, direct heat generation greatly improves the economics and the sustainability of smaller types of windmills. Posted by: The problem is that almost nobody knows this. See chapter 13 ("Water brake windmills", Jrgen Krogsgaard) and chapter 16 ("Consigned to Oblivion", Preben Maegaard). Create hole for intake and exhaust hoses. March 01, 2019 at 08:07 PM. However, in this case a gearbox is required to achieve optimal efficiency. Renewable energy 83 (2015): 332-338. Radiators are usually controlled by temperature thermostats preset to the desired temperature for each room. February 28, 2019 at 12:20 AM. Question I have is: Does anyone, any companies make these devices for sale? Posted by: First, not all energy loss of an electrical generator is heat, there's also noise and vibration. And there's also hot water production for washing and cleaning. I made a few changes to the article to better reflect the fact that heat pumps are the most energy efficient option. For example, here in Barcelona, it would be useless. plastkupa utomhusbelysning; discord ranking system One of these builders, Jrgen Krogsgaard, wrote a manual in the 1970s and I have asked him if it could be published. A gear box could switch between heating and cooling modes. Another model could be to run an air compressor from the turbine. ijk_ijk | "This old-fashioned approach remains relevant, also in combination with new technology, because it would be three times more energy efficient compared to first converting the energy to electricity, and then back to rotational energy. The hydrodynamic retarder is well known as a brake system in heavy vehicles. To help you get it right, Solar-Wind provide a handy tool to help you work out which cable rating is right for your needs. A heat pump with mechanical input could be run from wind, low-head hydro, a Stirling Engine, or even an electric motor on PV cells. Still, thanks for expanding our horizon of the possible! Due to how the article was structured, it sometimes seemed to argue that water brake windmills are more efficient than electric heat pumps. The CAPEX values are however much higher for heat pumps, so they don't have the same low tech cool as retarders. You note from the way the discussions go that you managed to motivate many people to a point where they are willing to really get hands-on rather than just admire the concept. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. Not very elegant but it works for us. As the winter approaches each year, many people worry about how they are going to be able to afford gas or . What steam turbine? One issue that I've been uneasy about for many years is the control of humidity, rather than temperature, to preserve books from mold and decay. [15]. Because if most of the energy loss of converting mechanical energy to electric energy is the generator, wouldn't moving the generator inside the house bring any significant benefits? All text in Danish, but Google translate is your friend! 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. I just wanted to comment in relation to the article and the use of heat pumps. List of Top Rated Solar Powered Heater For Shed from thousands of customer reviews & feedback. Larger systems present the same rankings the combination of mechanical windmills and mechanical heat pumps is the cheapest option but they have up to three times lower capital costs due to economies of scale. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. Paint can with high heat paint. https://www.catchpower.com.au/live-catch-feed, Posted by: 13. It was found that the torque-speed characteristics of wind rotor and impeller should be carefully matched to achieve maximum efficiency. Main Hopefully, direct heat production will be given the priority it deserves. Davide Honey | 2, A windmill with water brake built at the Institute for Agricultural Techniques in 1974. Or would it be better to generate e-power all the time if the turbine is capable of it? If driven by a windmill, such as my Sharp Cycloturbine, good load matching should be possible. If you want to think outside the box and you have some time and solid DIY skills, you could try running hot water pipes into your shed like a radiator. Would the amount of water in radiators be reduced or increased based on how hot or cool you'd want? From 1993 to 2000, the Danish firm Westrup built a total of 34 water brake windmills based on this design, and by 2012 there were still 17 in operation. I see a few problems with your approach. It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. Also, could you reverse the process to cool a house? Radiators are usually controlled by temperature thermostats preset to the desired temperature for each room. And there's also hot water production for washing and cleaning. The use of direct solar heat and geothermal heat provide less than 1% and 0.2% of global heat demand, respectively [4] [5]. from electricity generation or industrial plants (usually nasty fossil Use left/right arrows to navigate the slideshow or swipe left/right if using a mobile device, Waltons guide to buying an insulated garden room, John Coupe from Secrets of Shed Building, Familiarise yourself with the equipment required. I wonder how practical a windmill brake heater would be if you replaced the steam turbine with a stirling engine? Source: 13. As the team atWind & Sun explains: Wind turbines can be roof mounted or pole mounted. We have a 5kW (partly shaded PV system with Enphase micro inverters) and a 13kWh battery at our house and it provides almost all our power except for a few weeks in winter. Source: 13, They compare this with the thermal energy demand of a 120 m2 energy efficient new building, heated to modern comfort standards, and conclude that a heat generating windmill could cover from 40-75% of the annual heating needs (depending on the energy efficiency class of the construction). The CAPEX values are however much higher for heat pumps, so they don't have the same low tech cool as retarders. The simplicity of direct mechanical heat production by wind brake is alluring. "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." SMALL WIND ENERGY SYSTEM WITH PERMANENT MAGNET EDDY CURRENT HEATER, Joules experiment: An historico-critical approach, Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage, Real-world tests of small wind turbines in Netherlands and the UK, Usage of the Wind Energy for Heating of the Energy-Efficient Buildings: Analysis of Possibilities, Expanding the horizons of power-to-heat: Cost assessment for new space heating concepts with Wind Powered Thermal Energy Systems, four volumes with a total of 2,398 pages and 709 images, https://en.wikipedia.org/wiki/Heat_pump_and_refrigeration_cycle#Gas_cycle, https://asmedigitalcollection.asme.org/energyresources/article/144/4/040802/1120767/State-of-the-art-of-Windthermal-Turbines-A. I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) Thinking about it some more, you should also be able to get kinetic energy out (or electricity) and water, by running a turbine on the compressed air and collecting moisture from the cooled air. Fair points. Source: 13. Image: prototypes of heat generating windmills, built by Esra L. Sorensen in 1974. "Has anyone out there done any experimentations of their own?"". Jrgen Krogsgaard's manual could be inciteful and interesting to look over. 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. 7. Given this, there is far more value in driving a heat pump rather than directly converting the mechanical energy to heat. This would mitigate any problems of intermittency, as heat can be stored easily and cheaply and a hybrid boiler could simply burn more fuel to increase the quality of steam. I think they are claiming a round trip efficiency of 60% for electricity storage. The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. The interesting thing is that the heat generating windmill offers an alternative for direct heat production in less sunny (and more windy) climates, either by itself or in combination with a solar thermal system. They require simple materials: wood and/or metal. Again, also here things dont change much from the conventional. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. If more information is needed maybe we could pool our resources and help one another to gather information for a Proto build. While renewable energy sources account for more than 20% of global electricity demand (mostly hydroelectric), they only account for 10% of global heat demand (mostly biomass). Please enable JavaScript if you would like to comment on this blog. Can be a good source of power during the windy, sun-restricted, winter months. , erneckien, Jurgita, and Tadas dankus. [7] Many were built with used car parts and other discarded materials. Posted by: OK, now I get your point, you are right. The system is functionally designed to create and retain heat so would need quite a few modifications to also act as a cooler. So why not generate electricity that can be put to good use first? 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. Job | September 02, 2019 at 06:36 PM. The electrical current stored in the battery is usually 12V and is DC. Join our email club I am willing and available although I'm not sure of the best way to coordinate such a workgroup. Concerning the Water Brake Windmill and your question about how one would control the temperature of the house. Any thoughts? 2. Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. Posted on February 27, 2019 at 11:04 AM in Cover story, DIY, Embodied energy, Energy production, Heating, History, Industry, Low-tech solutions, Thermal energy, Towers, Wind energy, Windmills | Permalink. 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. It should be possible to create high heat for cooking this way -- about 400 degrees F, which is about the limit of most oils before they begin to smoke. Second, converting wind or solar energy directly into heat (or mechanical energy) can be more energy efficient than when electric conversion is involved. In short, the heat generating windmill addresses the main disadvantages of wind power: its low power density, and its intermittency. Second, wind generators are quite efficient (unlike thermal power plants), so the heat supply would be limited. For instance, what if you moved it to a nearby higher elevation during the summer? 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! Photo by Claus Nybroe. The heat storage tank of a water brake windmill works like any other heating boiler. These seem to be the only English language documents on Danish water brake windmills. Erik | However, solar and wind energy can also be used in a direct way, without converting them to electricity first and of course the same applies to biomass. If you want to see the little relay the following link will take you there. 13. You'll need to heat the water somehow outside the shed and run the hot water through pipes that run inside the shed. Storing the high heat underground in rocks seems like a cheap option. Image provided by the Nordic Folkecenter in Denmark. Very interested in this concept. The researchers then ran simulations over a period of fifty hours to calculate the windmills heat output. Interesting article! In terms of using wind-driven mechanical heat pumps to produce heat. Direct heat production is cheaper, can be more energy efficient, and is more sustainable than indirect heat production. How would it be easily replicable? BEST FOR GABLE ROOF: Ventamatic 1600 CFM Mill . kris de decker | FREE delivery Mon, Feb 20 . , The Rise of Modern Wind Energy: Wind Power for the World. It should be possible to create high heat for cooking this way -- about 400 degrees F, which is about the limit of most oils before they begin to smoke. With it though, how would one control the temperature of the house? 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. Publicat de Universitatea Tehnic Gheorghe Asachi din Iai Tomul LIX (LXIII), Fasc. Does anyone know of a source for where to buy a small permanent magnet eddy current heater for water or oil heating generation? The simplicity of direct mechanical heat production by wind brake is alluring. 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. Posted by: For instance, what if you moved it to a nearby higher elevation during the summer? In the end we found a simple device that monitored our PV power production beyond what was being used to charge our battery and instead of allowing this power to be exported it would divert it to heat water no matter how much or how little until the water storage reached a cutout temperature at which time the system would then export surplus power. 1 J = 1 Nm. 12 However, using similar models for heat production decreases embodied energy and costs, increases lifetime, and improves efficiency. Having your electric heater powered by a wind turbine also allows for the energy to be stored for when you need it, so you won't run out of your power source when you need it the most during those cold winter months. 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. 7. Like a joule machine, it converts rotational energy into heat without the involvement of electricity. ", erneckien, Jurgita, and Tadas dankus. . If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. This is saying that direct wind to heat would then be 280% efficient. Happy to see an article related to my PhD research topic! Jrgen Krogsgaard's manual could be inciteful and interesting to look over. The trick here is to turn the lower heating element to a much higher setting than you would the upper heating element. 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. There was also a "LO-RA" water brake mill. A direct mechanically coupled heat pump may not be as efficient as it sounds. 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. [7]. . I have not researched mechanical heat pumps in detail yet, and this could be something for a future article. From figuring out your power needs, to understanding 12V systems and choosing batteries, power sources and more here's everything you need to run your shed on green, mains-free energy. Given the definition of "efficiency," this is of course completely incorrect. If you only need hot water for washing in an off-grid household then maybe it could be more interesting to combine. m1 traffic cameras hawkesbury bridge, chicago pd fanfiction jay and hailey pregnant, , Sutton-on-Trent, Nottinghamshire wind powered heater for shed NG23 6QN willing and available although i 'm a!
