For example, when I was a student and still owned a desktop instead of a laptop, I has a set-up where I had put a blanket around my desk like a make-shift kotatsu, with the computer desktop poking through. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger. 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. New paper on heat mills: https://asmedigitalcollection.asme.org/energyresources/article/144/4/040802/1120767/State-of-the-art-of-Windthermal-Turbines-A, Nitto, Dipl-Ing Alejandro Nicols, Carsten Agert, and Yvonne Scholz. I have not researched mechanical heat pumps in detail yet, and this could be something for a future article. January 05, 2023 at 07:29 PM. 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). 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. And more efficient. [13]. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. But that's because you heat people, not spaces. Image provided by the Nordic Folkecenter in Denmark. 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. 10 Best Wind Powered Greenhouse Heater for 2023 List of Top Rated Wind Powered Greenhouse Heater from thousands of customer reviews & feedback. Again, also here things dont change much from the conventional. These are comprised of a magnet mounted on a rotating shaft, and can reach temperatures of up to 600 degrees Celsius. The wind speed you mention is not common indeed but it is not necessary either. The result is heat generated by wind energy. A gear box could switch between heating and cooling modes. 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? In this case, it becomes possible to build a pretty reliable heating system with a smaller heat storage tank, because the combination of two often complementary energy sources increases the chances of direct heat supply. March 03, 2019 at 01:04 PM. Photonic Universe provides a useful chart that matches the power consumption of electrical items you intend to use in your shed, to the power rating required from your inverter, which well discuss in the next section. 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. March 12, 2019 at 11:32 AM. This is comparable to the heat output of the smallest electric boilers for space heating. Still, thanks for expanding our horizon of the possible! 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. Posted by: Water brake windmills may be a lot cheaper to build, but they are not more energy efficient because a heat pump only moves heat. Because the Danes already had a strong DIY-culture for small wind turbines generating electricity on farms, they started building windmills to heat their houses. As for what you could actually expect from running a wind turbine directly to a room heater, the answer is: trouble. You feed that to a 500 Watt heater. 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. Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. I just wanted to comment in relation to the article and the use of heat pumps. For example, you could build a desk or a bench with water pipes inside, heated by a small mechanical windmill and heat storage. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. 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. The letters and numbers you entered did not match the image. 10. I think this technology could be great for island communities in higher latitudes. Lathechuck | Good question. Theres two reasons for this. March 06, 2019 at 11:45 AM. All text in Danish, but Google translate is your friend! Obviously, its not always stormy weather, which means that the average wind speed is at least as important. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels. The simplicity of direct mechanical heat production by wind brake is alluring. Heat pumps are certainly the most efficient way to heat either stored water or a house directly however they do not operate on a varying amounts of input power as does simple resistance heating. Third, you lose a significant cost advantage because you reintroduce all the electric components. When I asked about anyone out there doing any experimentations of their own, I was thinking more about your "readers" than the Danish tinkerers. 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. Of cause it is not economical to have that much storage. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. This would be dependent on a total volume large enough to absorb the whole days worth of heat or dual pump water into house then through ground pipes to recool it. Posted by: Mechanical windmills are less complex, which makes them more affordable and less resource-intensive to build, and which increases their lifetime. In total, at least a dozen different models have been documented, both DIY and commercial models. "Expanding the horizons of power-to-heat: Cost assessment for new space heating concepts with Wind Powered Thermal Energy Systems." Energy 164 (2018): 925-936. From the Neolithic to the beginning of the twentieth century, coppiced woodlands, pollarded trees, and hedgerows provided people with a sustainable supply of energy, materials, and food. We are designing the device specifically for the needs of Newfoundlander and for that we want your input. 7- DIY Solar Panel Air Heater Another ingenious design that enable you to build a solar garage heater using recycled soda cans. 12 However, using similar models for heat production decreases embodied energy and costs, increases lifetime, and improves efficiency. Maybe a storage system with both hot and cold stores might be interesting. Lava Heat Italia CAPRI-A-LINE-6MPB Propane Heater$1,010. ijk_ijk | Key Features: Choice of three heating settings: 30W (fan only), 1500W, and 3000W Integrated, adjustable thermostat control (0-850) The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. Job van der Zwan | Or is it just controlling the flow rate of the water? A heat generating windmill with a water brake, placed inside the bottom of the tower. I'll keep you updated here in the comments section. On the other hand, the combination of a small wind turbine and an electric heat pump requires a windmill with a capacity factor of at least 30% to become cost-competitive with gas heating but such high performance is very unusual. Larger heat generating windmills were built in the 1980s. 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. First, thank you for putting up such an interesting web site. Different types of direct and indirect heating production compared. March 03, 2019 at 09:05 PM. Towards the end you touched upon on windmills directly driving the shaft of heat pumps. Also, how would you transfer the waste heat from the generator to the heat medium? Photo by Ricard Matzen. 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. I'm wondering if the idea of a heat mill would combine well with a tethered balloon or kite wind system? The writer of the book chapter may know, but he didn't answer my questions. As the team atWind & Sun explains: Wind turbines can be roof mounted or pole mounted. 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. To simplify the process of powering your shed, there are kits available with all the parts you need included. [1], One type of heat generating windmill converts rotational energy directly into heat by generating friction in water, using a so-called water brake or Joule Machine. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. However, an old-fashioned windmill can not only provide mechanical energy, but also thermal energy. For example, you could build a desk or a bench with water pipes inside, heated by a small mechanical windmill and heat storage. Nitto, Dipl-Ing Alejandro Nicols, Carsten Agert, and Yvonne Scholz. Ecoheater 1000mm Slimline Greenhouse & Shed Heater HHT310 (120W) Read Review. [5] [6]. Brendan Howell | Russ Mattson | However, in both cases, if you want to heat your house with wind power, a simple water brake windmill seems to me like the best choice. Images from Test at very high wind speed of a windmill controlled by a water brake, O. Helgason and, Posted on February 27, 2019 at 11:04 AM in, Keeping Some of the Lights On: Redefining Energy Security, 2-3 times as energy efficient compared to following the indirect path involving electricity conversion, very inefficient and dont always generate as much energy as was needed to produce them, compared to batteries or other common technologies, when solar thermal is used for power production, Ditch the batteries: off-grid compressed air energy storage, Keeping some of the lights on: redefining energy security, Restoring the old way of warming: heating people, not places, Wind powered factories: history and future of industrial windmills, WIND POWERED THERMAL ENERGY SYSTEMS (WTES), Integration of Thermal Energy Storage into Energy Network, The bright future of solar thermal powered factories. 99. Registered Address: Old Great North Road, Sutton-on-Trent, Nottinghamshire, NG23 6QN. I'll post their reply (if it comes) here in the comments section. Generate storable heat during off-peak hours. This adds back an electric generator to the system but it only has to be sized for average power*, not peak windy day power, 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. 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. Parasene. They conclude that a mechanical heat pump + mechanical windmill is the most cost effective realization of wind powered heating. This old-fashioned approach remains relevant, also in combination with new technology, because it would be more energy efficient compared to first converting the energy to electricity, and then back to rotational energy. Does anyone have one for purchase and test? All text in Danish, but Google translate is your friend! Renewable energy production is almost entirely aimed at the generation of electricity. Your comment has not yet been posted. For the off-grid system, directly coupling a mechanical windmill to a mechanical heat pump is the cheapest option, while the combination of a wind turbine and an electric boiler is two to three times more expensive. Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. 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. ", Okazaki, Toru, Yasuyuki Shirai, and Taketsune Nakamura. lambda expression cannot be converted to expression tree. This is not about math, it's about language. https://www.catchpower.com.au/live-catch-feed. BULETINUL INSTITUTULUI POLITEHNIC DIN IAI. In practice I heat my home and hot water with a heat pump powered by renewable electricity, with a bit of solar thermal boost. Image provided by the, Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). Almost nobody knows that a windmill can produce heat directly. Not sure about your approach though. 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. 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. Dimitar Bounov | Any thoughts? Most used simple wooden blades. Or some pointers on the formulas to figure this out ourselves? kris de decker | There are quite a few district heating systems which use waste heat from electricity generation or industrial plants (usually nasty fossil or nuclear stuff) but it seems like a Water-brake wind system could be plugged into these to make them greener. 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. 2. Photo by Ricard Matzen. @Kris I'm not seeing the contradiction in [15]. Retarders and mechanical heat pumps have the same advantages as Joule Machines, in the sense that they are much smaller, lighter, and cheaper than electrical generators. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). 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. , Chakirov, Roustiam, and Yuriy Vagapov. [1] In temperate or cold climates, the share of thermal energy is even higher. BTW, I am off grid, and do have practical experience. Overload your circuit and it will overheat and could catch fire; go for too high a rating and youre just wasting money. ", erneckien, Jurgita, and Tadas dankus. 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. However, in both cases, if you want to heat your house with wind power, a simple water brake windmill seems to me like the best choice. February 28, 2019 at 12:27 AM, "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.". For example how much more heat do you get when you use ground loops or ground water vs outside air? A much larger water brake windmill (7.5m rotor diameter, 17m tower) was built in 1982 by the Svaneborg brothers, and heated the house of one of them (the other brother opted for a wind turbine and an electric heating system). A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. Subject: To build a water brake windmill from scratch. To work out the power rating of your inverter, simply add up the required wattage of all the equipment you'll be using. It makes so much sense. Here it is: http://www.langdal5.dk/energi/info.html, Posted by: SHOP OUR RANGE OF MODULAR SHEDS NOW. Journal of Sustainable Architecture and Civil Engineering 10.1 (2015): 58-65. Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. Check Price 35% OFF. A division of This can happen automatically via a temperature limiting switch located on your water storage tank which tells the system when to turn off the windmill. Sorry for the silly question! What do you think? Another model could be to run an air compressor from the turbine. When the heating is turned on, the water is pumped through the house and then flows back into the tank, where it can be heated again. Check Price. 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. Very interesting article! Solar thermal energy can be used for water heating, space heating or industrial processes, and this is 2-3 times as energy efficient compared to following the indirect path involving electricity conversion. March 11, 2019 at 09:56 AM. Obviously not everyone has space for a heat generating windmill, but there's no need to put a windmill next to each house. I did not look into wind powered cooling but it could be possible. Happy to see an article related to my PhD research topic! I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) Due to efficiency heatpumps are intermittent energy demand. > Has anyone out there done any experimentations of their own? 8 A 2013 study using a prototype obtained similar results, and calculated the efficiency of the system to be 91%. , Cao, Karl-Kin, et al. Posted by: You could build small networks for heat distribution, in which one or a few windmills supply heat to a community of buildings or a factory. 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. It is much more practical to use solar thermal. The plan is for a passive heater made with soda cans, an old window, and some insulation. Could be a topic for a future article. In the meantime, if anyone else has more info, feel free to share it. I thoroughly enjoyed the article on heating with windmills. I see a few problems with your approach. March 02, 2019 at 08:15 PM. How to Build a Practical Household Bike Generator, The Printed Website: Volume III & The Comments. Reuben Lewis | 7 Many were built with used car parts and other discarded materials. Also say you've got the 20 mph wind consistent enough to sustain the power output. If not where would I find suppliers for this type of turbine? Image: the heat generator of a heat generating windmill. Posted by: This is much better than the 30% of the molten salt. Posted by: 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. The wind-powered heater can heat water for domestic or industrial purposes directly from wind energy. 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. Adjusting energy demand to supply would make switching to renewable energy much more realistic than it is today. 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. For example in the UK, heat counts for almost half of total energy use. [13], One of the smaller early Danish heat generating windmills was officially tested. 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) Installing a 20,000L tank is a significant expense, but might be worth it in areas with intermittent access to water or drought conditions. 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? That way it would be kept simple. Illustration: Rona Binay for Low-tech Magazine. This adds back an electric generator to the system but it only has to be sized for average power*, not peak windy day power, Mr Beams MB390 300-Lumen Weatherproof Wireless Battery Powered LED Ultra Bright Spotlight with Motion Sensor, Brown Read Review. solar [at] lowtechmagazine [dot] com, This is a solar-powered website, which means it sometimes goes offline, more energy efficient compared to first converting the energy to electricity, and then back to rotational energy, very inefficient and dont always generate as much energy as was needed to produce them, when solar thermal is used for power production, WIND POWERED THERMAL ENERGY SYSTEMS (WTES), Integration of Thermal Energy Storage into Energy Network, The bright future of solar thermal powered factories, Direct conversion of wind energy into heat using joule machine, 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, Keeping Some of the Lights On: Redefining Energy Security. 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. Free delivery to most postcodes. 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. Ian Speer | If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. 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.
