Posted by: 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. I went looking for a source for eddy current heaters, however, and came up with nothing. Because heat can be stored much more cheaply than electricity, a two-days storm can give heat for a week or longer. 7, 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). February 27, 2019 at 07:03 PM. The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. https://www.catchpower.com.au/live-catch-feed. So I experimented a bit toward creating more concentrated heat at a high temperature. How to design a sailing ship for the 21st century? Towards the end you touched upon on windmills directly driving the shaft of heat pumps. Question I have is: Does anyone, any companies make these devices for sale? Posted by: Due to how the article was structured, it sometimes seemed to argue that water brake windmills are more efficient than electric heat pumps. Read Review PK Green Check Price 2 Note that the statement you quote is about mechanical energy, not about heat. 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. The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. Ideas anyone? Or they could be fabricated locally. A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. No. Registered Address: Old Great North Road, Sutton-on-Trent, Nottinghamshire, NG23 6QN. 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. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. Thanks for your speedy reply. 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. Too much cheap energy from the fossil fuel for too many years has turned us unable to see these kind of solutions. First, not all energy loss of an electrical generator is heat, there's also noise and vibration. If not where would I find suppliers for this type of turbine? A gear box would help, but this adds complexity. List of Top Rated Solar Powered Heater For Shed from thousands of customer reviews & feedback. Kris De Decker | Second, wind generators are quite efficient (unlike thermal power plants), so the heat supply would be limited. OK, now I get your point, you are right. 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. I built a water brake using a paint can and spun it with my drill press. 2. 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). 15. Illustration: Rona Binay for Low-tech Magazine. Call Us: 0800 029 1000 Lines Open Until 5PM If you can afford it, a combination of both wind and solar power gives you the best of both worlds. Comments are moderated and will not appear until approved by the author. March 11, 2019 at 02:53 PM. Even the International Energy Agency doesn't mention direct conversion of wind into heat when it presents all possible options for renewable heat production. You can install a bank of more than one battery to increase the available power store. Kris - thanks a lot for this great article, very inspiring! The four heating concepts are ranked based on their yearly capital and operational expenditures, assuming a lifespan of 20 years. Once you have a mechanical-input heat pump, it's a simple matter of rerouting the refrigerant flow as to whether the machine extracts heat from the outdoors, and brings it inside, or vice versa. It's mechanical windmills with mechanical heat pumps that are more energy efficient (and cheaper) than wind turbines with electrical heat pumps. It appears much of the ancillary apparatus could be sourced many places. March 03, 2019 at 07:52 PM. 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). Anyway it's not a point - end goal is to reduce our dependence on resources, Posted by: If in doubt, contact them directly for advice. Mario Stoltz | March 03, 2019 at 09:05 PM. Photo by Claus Nybroe. Your comment could not be posted. Image provided by the Nordic Folkecenter in Denmark. For the moment, there's no other option than to build a water brake windmill from scratch. Posted by: I went looking for a source for eddy current heaters, however, and came up with nothing. Ideas anyone? 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) A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. They move heat energy from outside, making an already cool outside a little colder, to inside your house making it warmer. 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. This means that less solar and wind energy converters and thus less space and resources are needed to supply a certain amount of heat. Source: [7]. The aim of the concept is to utilize wind power instead of conventional wood burning method in order to keep people warm in the cold months. 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. , The Rise of Modern Wind Energy: Wind Power for the World. ", Okazaki, Toru, Yasuyuki Shirai, and Taketsune Nakamura. March 01, 2019 at 08:07 PM. 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. 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. 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. Also, could you reverse the process to cool a house? 2) Open fireside BBQ grill with charcoal. 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). Windmills have braking systems that can stop them from turning when you dont need their energy to impute. The researchers then ran simulations over a period of fifty hours to calculate the windmills heat output. 10. > Has anyone out there done any experimentations of their own? 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. Second, converting wind or solar energy directly into heat (or mechanical energy) can be more energy efficient than when electric conversion is involved. This article is amazing and I love the idea of this. 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. I see a few problems with your approach. In particular, the electric heat pump is promoted by many governments and organisations as a sustainable solution for renewable heat generation. Toby | Anthony | 7. Again, also here things dont change much from the conventional. to receive exclusive offers and discounts. 15. It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. Hopefully, direct heat production will be given the priority it deserves. February 28, 2019 at 12:36 AM. Posted by: Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. *maybe buffered by an hour or two of battery back-up to allow some flexibility. Does anyone know of a source for where to buy a small permanent magnet eddy current heater for water or oil heating generation? Like a joule machine, it converts rotational energy into heat without the involvement of electricity. I don't have the answer but I've sent a mail to some scientists who wrote about the eddy current heater. Fair points. Publicat de Universitatea Tehnic Gheorghe Asachi din Iai Tomul LIX (LXIII), Fasc. 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. The " how to keep a shed warm without electricity " is a guide that tells users how they can heat their sheds without using electricity. The amount of power you require dictates the type of system you install, so calculating your power requirements is key to setting up a system that works for you. Posted by: Walton Web is authorised and regulated by the Financial Conduct Authority, registration number 620773. Credit is subject to status. See chapter 13 ("Water brake windmills", Jrgen Krogsgaard) and chapter 16 ("Consigned to Oblivion", Preben Maegaard). Well, there is a great problem in that an average wind speed of 11 mps is rare.that is nearly 25mph. The letters and numbers you entered did not match the image. February 27, 2019 at 11:45 PM. The heat storage tank of a water brake windmill works like any other heating boiler. The question is how does one turn the heat producing source (the windmill)on and off. In particular, the electric heat pump is promoted by many governments and organisations as a sustainable solution for renewable heat generation. kris de decker | The direct alternative for solar photovoltaic power is solar thermal power, a technology that appeared in the nineteenth century following cheaper production technologies for glass and mirrors. The thing about heat pumps is that they move more heat energy than it takes to drive them. Due to the large energy losses for heat transportation, 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 small city. Posted by: Its heat output was estimated to be 90 kilowatt at a wind speed of 14 m/s (Beaufort 7). Posted by: [12] However, using similar models for heat production can decrease embodied energy and costs, increass lifetime, and improve efficiency. 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. 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. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger. Mario Stoltz | Email address will not be displayed with the comment.). Runner-up space heater: Vornado AVH10. The trick here is to turn the lower heating element to a much higher setting than you would the upper heating element. Due to friction among molecules of the water, mechanical energy is converted into heat energy. It took a long time to heat the water and required good insulation. [3], In spite of this, renewable energy sources play a negligible role in heat production. Still, thanks for expanding our horizon of the possible! The researchers explain and illustrate the workings of the water brake windmill, and calculate the optimal performance of the technology. Erik | It transferred the rotational energy from its wind rotor directly to the axis of a machine, for example for sawing wood or grinding grain. 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). Heat storage can solve this issue but it requires the storage capacity to store 'few months' of generation to fully decouple the generation and demand. Interesting article! BEST HARD-WIRED POWERED: Master Flow 1000 CFM Mill Power Roof Mount Attic Fan. In total, at least a dozen different models have been documented, both DIY and commercial models. HeadakusMaximus | I'll keep you updated here in the comments section. Most used simple wooden blades. February 28, 2019 at 11:41 AM. It uses a patented and innovative device called a Magnetodynamic Heater that works with magnetic induced Eddy currents to produce heat. With it though, how would one control the temperature of the house? "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." 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. For example, here in Barcelona, it would be useless. The electrical current stored in the battery is usually 12V and is DC. 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. Photo by Claus Nybroe. Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) Very interesting article! page for more details. Murray Read | 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. 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. 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. 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. [5] [6]. 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! 7. A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. I just wanted to comment in relation to the article and the use of heat pumps. In terms of using wind-driven mechanical heat pumps to produce heat. 7 8 9, Image; a heating system based on a water brake windmill. 14 The researchers calculated that at the average wind speed in the country (4 m/s of Beaufort 3), generating one kilowatt of heat requires a windmill with a rotor diameter of 8.2 meters. 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. [13]. The Wind Heater by Korean designer Jihae Kim presents a sustainable technological heating solution during harsh winters. As for what you could actually expect from running a wind turbine directly to a room heater, the answer is: trouble. What I don't quite understand is: heat will be a byproduct of using electricity anyway, since it is always the waste product in the end. 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. 7, Further into the 1980s, Knud Berthou built the most sophisticated heat generating windmill to date: the LO-FA. 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. Too much cheap energy from the fossil fuel for too many years has turned us unable to see these kind of solutions. 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. You introduce extra losses in the mechanical drive train just to get a little bit of waste heat -- and a lot of noise and vibrations -- in the house. It was found that the torque-speed characteristics of wind rotor and impeller should be carefully matched to achieve maximum efficiency. Due to efficiency heatpumps are intermittent energy demand. The writer of the book chapter may know, but he didn't answer my questions. , themes: Off-the-grid energy storage Heating and cooling Wind power Renewable energy History. the generator is not up on the tower (requiring a stronger tower). I would believe 30% more efficient. *maybe buffered by an hour or two of battery back-up to allow some flexibility, Posted by: When I asked about anyone out there doing any experimentations of their own, I was thinking more about your "readers" than the Danish tinkerers. > But that's because you heat people, not spaces. Keeping Some of the Lights On: Redefining Energy Security | It transferred the rotational energy from its wind rotor directly to the axis of a machine, for example for sawing wood or grinding grain. 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. 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. , Selfbuilders, Winds of Change website, Erik Grove-Nielsen. 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. These panels can be sited either on the ground nearby, or on the shed roof itself. Direct heat production is cheaper, can be more energy efficient, and is more sustainable than indirect heat production. 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. Like being commercialised by high view power. Also, designing some cavitation into the submersed rotor might increase the rate of heating. A heat generating windmill with a water brake, placed inside the bottom of the tower. Walton Web Ltd 2019. 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. 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. Join our email club Here it is: http://www.langdal5.dk/energi/info.html. Energy 164 (2018): 925-936. Generate storable heat during off-peak hours. Job van der Zwan | OK, now I get your point, you are right. They conclude that a mechanical heat pump + mechanical windmill is the most cost effective realization of wind powered heating. Are there tables out there that specify what house area can be heated to what temperature differential at what wind speeds? December 13, 2021 at 11:30 PM, New paper on heat mills: https://asmedigitalcollection.asme.org/energyresources/article/144/4/040802/1120767/State-of-the-art-of-Windthermal-Turbines-A, Posted by: For example, you could build a desk or a bench with water pipes inside, heated by a small mechanical windmill and heat storage. 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. The CAPEX values are however much higher for heat pumps, so they don't have the same low tech cool as retarders. This means that less solar and wind energy converters and thus less space and resources are needed to supply a certain amount of heat. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. Chuck Hays | Installing a 20,000L tank is a significant expense, but might be worth it in areas with intermittent access to water or drought conditions. "Has anyone out there done any experimentations of their own?"". 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. Again, also here things dont change much from the conventional. They require simple materials: wood and/or metal. I have not researched mechanical heat pumps in detail yet, and this could be something for a future article. The average cost of a small roof-mounted turbine (between 0.5 kW to 2.5 kW), is about 2,000 5. fake by any means necessary jacket. First, and most importantly, mechanical windmills are less complex, which makes them more affordable and less resource-intensive to build, and which increases their lifetime. 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. 3. I think that moving the electric generator inside is the worst of both worlds. Fourth International Conference on Environmental and Computer Science (ICECS 2011), Singapore, Sept. 2011. Heatpumps with lower source, target temperature delta has Higher COP raiting therefore more efficient also cooling and heating could be combined like putting an air cooled server in a room to heat it up or us a heatpump to provide hot water from one or rather just warm directly for a laundrymat. Also great for even, oscillating heat .
