I see a few problems with your approach. I wonder how practical a windmill brake heater would be if you replaced the steam turbine with a stirling engine? It is much more practical to use solar thermal. One option is to use source heat that does not have to be maintained and a storage tank. 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). Posted by: Some exclusions apply. It also features a built-in overheat protection system to prevent the heater from overheating. Anthony | However, using the stored heat for electricity production is considerably more costly and less sustainable compared ro using heat generating windmills for direct heat production. It's cheaper than my oil fired neighbours, 100% carbon free and practical for many people to install now. [15]. 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 windmills have higher capacity factors (16-40%), which result in even larger cost savings. Erik | 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. 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. Posted by: If you follow that approach, you win indeed. It's probably going to be less practical compared to using a water brake."". February 28, 2019 at 12:36 AM. As for what you could actually expect from running a wind turbine directly to a room heater, the answer is: trouble. 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. 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. However, we use more energy in the form of heat, which solar panels and wind turbines can produce only indirectly and relatively inefficiently. BTW, I am off grid, and do have practical experience. Images from Test at very high wind speed of a windmill controlled by a water brake, O. Helgason andA.S. Sigurdson, Science Institute, University of Iceland. However, in this case a gearbox is required to achieve optimal efficiency. or nuclear stuff) but it seems like a Water-brake wind system could be I absolutely hate the "new" math illiteracy. Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. ", (note: 3x AS efficient is not the same as 3x MORE efficient). So, let's say wind -> electric -> heat gives an overall efficiency of 70%. 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. A gear box could switch between heating and cooling modes. ". Obviously a water brake windmill is suited for a windy climate. Too much cheap energy from the fossil fuel for too many years has turned us unable to see these kind of solutions. All Rights Reserved. There was also a "LO-RA" water brake mill. 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. , Renewables 2018, Heat, International Energy Agency (IEA). No reviews. For the moment, there's no other option than to build a water brake windmill from scratch. Of course, there are other ways but this is the simplest solution. 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. 7. , 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). 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. The same windmill as the one pictured above, seen from below. March 01, 2019 at 07:46 PM. I believe the research institute of your reference [15] - DLR (German Aerospace Centre) do have a project to build and test a prototype of this kind of system. A UK based solar system could suffer from a lack of available sunshine, particularly in the winter months. The researchers then ran simulations over a period of fifty hours to calculate the windmills heat output. March 06, 2019 at 11:45 AM. Overload your circuit and it will overheat and could catch fire; go for too high a rating and youre just wasting money. Source: [13]. 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. 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. Arturs | Ft. . How to design a sailing ship for the 21st century? Taking your shed off-grid is simple to achieve, good for the environment, and could save money in the long-term. Or would it be better to generate e-power all the time if the turbine is capable of it? A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. Ideas anyone? I wonder, if heat-generating windmills allow lightweight windmills to be economical, would that mean that they could also be portable? Please enable JavaScript if you would like to comment on this blog. Has anyone out there done any experimentations of their own? However, in the LO-FA windmill all mechanical parts for energy conversion were moved to the top of the tower. Correct positioning is very important but is not always easy to achieve, particularly when the cost of the cable limits where you can site your turbine. URLs automatically linked. 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. It's probably going to be less practical compared to using a water brake. Most turbine manufacturers provide wind energy system packages that include towers. 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. metals), no generator, fewer controls necessary (associated with frequency control, transformation etc), turn rotational motion directly into heat (especially if all you want is the heat from the wind). 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. 3, In spite of this, renewable energy sources play a negligible role in heat production. Even while distributing a large amount of heat, the Mr. Heater Hero stays cool to the touch. Can be a good source of power during the windy, sun-restricted, winter months. How would it be easily replicable? > Has anyone out there done any experimentations of their own? Clean the cans and punch out 3 holes in the bottom of each can. Keeping Some of the Lights On: Redefining Energy Security | Third, you lose a significant cost advantage because you reintroduce all the electric components. Like the stangenkunst that you dedicated a few articles too? Converting the stored heat into electricity is at most 30% efficient, meaning that two thirds of the wind energy is lost due to needless energy conversions -- and the same is true when solar thermal is used for power production. 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. Show sites now open. what it has going for it is a large volume of water in an insulated box . In other models, heat generation happened at the bottom of the tower from the top of the windmill there was a shaft down to the bottom where the water brake was installed. Parasene. ), (Name is required. If driven by a windmill, such as my Sharp Cycloturbine, good load matching should be possible. James Joule built it in the 1840s for his famous measurement of the mechanical equivalent of heat: one calorie equals the amount of energy required to raise the temperature of 1 cubic centimeter of water by 1 degree Celsius. 12 However, using similar models for heat production decreases embodied energy and costs, increases lifetime, and improves efficiency. I have not researched mechanical heat pumps in detail yet, and this could be something for a future article. No idea what "LO-FA" stands for. With it though, how would one control the temperature of the house? 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. Source: 8. 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? 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). The result is heat generated by wind energy. The printed archives now amount to four volumes with a total of 2,398 pages and 709 images. Would the heat be sufficient to kill pathogens in the water tank for longer-term water storage? 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. I went looking for a source for eddy current heaters, however, and came up with nothing. It makes so much sense. 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. Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. 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. Like a joule machine, it converts rotational energy into heat without the involvement of electricity. The oil then transferred its heat to the water storage in the tower. They require simple materials: wood and/or metal. But that's because you heat people, not spaces. Dimitar Bounov | Fitted to a wind turbine system, a run / stop switch enables you to temporarily slow down and/or stop the turbine from operating should you wish to, for example, to reposition it. February 27, 2019 at 08:02 PM. The use of direct solar heat and geothermal heat provide less than 1% and 0.2% of global heat demand, respectively [4] [5]. Posted by: Obviously not everyone has space for a heat generating windmill, but there's no need to put a windmill next to each house. [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. 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. 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. , Okazaki, Toru, Yasuyuki Shirai, and Taketsune Nakamura. Please try again. The heater requires a specific battery or electricity to ignite the propane and run the fans that blow out the hot air. Kris De Decker | If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. February 28, 2019 at 11:41 AM. 5 6. Like the stangenkunst that you dedicated a few articles too? 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. Much simpler, less material (i.e. Especially in less sunny climates, heat generating windmills are a great addition to a solar thermal system, because the latter produces relatively less heat during winter, when heat demand is at its maximum. Or they could be fabricated locally. The calorie was defined already in 1824. [Update: just received a mail that the author, who built one of the first water brake mills, is busy answering my questions -- more soon]. , Real-world tests of small wind turbines in Netherlands and the UK, Kris De Decker, The Oil Drum, 2010. , Selfbuilders, Winds of Change website, Erik Grove-Nielsen. Could this heat storage via water tank double as a way to store potable water? To simplify the process of powering your shed, there are kits available with all the parts you need included. 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. Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heatingsystem. By installing a solar powered water heater in your shed, you can make use of those solar panels to deliver the power of the sun into the heating element of the water heater itself. $59.99 $ 59. Create hole for intake and exhaust hoses. I think I would like to experiment with this idea and build a mini Water Brake Windmill with the intent of heating a small off grid house. For example in the UK, heat counts for almost half of total energy use. 7, Interest in heat generating windmills resurfaced a few years ago, although for now it concerns only a handful of scientific studies. [1] [15]. Illustration: Rona Binay for Low-tech Magazine. Of course that's impossible, so what the author wrote is obviously not what he meant. 4, 2013, Joules experiment: An historico-critical approach, Marcos Pou Gallo Advisor. That said PV panels are so cheap now particularly as many people are upgrading that a simple resistance water heater does the job and probably for rather less than a heat pump. Greenhouse, Dog House, Shed, Gable, Attic. Or fastest delivery Fri, Feb 17 . 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. I went looking for a source for eddy current heaters, however, and came up with nothing. If you want to see the little relay the following link will take you there. "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." I built a water brake using a paint can and spun it with my drill press. CrazyGadget Large Paraffin Super Warm Heater Single Burner Warmer Greenhouse Green House Plant Seeding Read Review. Good question. What do you think? This prevents automated programs from posting comments. Even the International Energy Agency doesn't mention direct conversion of wind into heat when it presents all possible options for renewable heat production. 1 J = 1 Nm. Posted by: 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. Murray Read | This article is amazing and I love the idea of this. [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. 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. March 11, 2019 at 09:56 AM. Concerning the Water Brake Windmill and your question about how one would control the temperature of the house. The LO-FA was also the largest of the heat generating windmills, with a 12 meter diameter rotor. Are there tables out there that specify what house area can be heated to what temperature differential at what wind speeds? 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. These are comprised of a magnet mounted on a rotating shaft, and can reach temperatures of up to 600 degrees Celsius. Subject: To build a water brake windmill from scratch. Too much cheap energy from the fossil fuel for too many years has turned us unable to see these kind of solutions. 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. , World Bank: Renewable electricity output. Posted by: Local heating can also be combined with direct heat production, and then you win even more. Posted by: Also great for even, oscillating heat . Barton Chen | If oil or pressurised water could be used as the brake fluid, then much higher temperatures could be achieved. Furthermore, the friction liquid in the water brake was not water but hydraulic oil, which can be heated up to much higher temperatures. [7]. Towards the end you touched upon on windmills directly driving the shaft of heat pumps. > But that's because you heat people, not spaces. Are there tables out there that specify what house area can be heated to what temperature differential at what wind speeds? Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. For example in the UK, heat counts for almost half of total energy use. This is saying that direct wind to heat would then be 280% efficient. "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 Wind Heater by Korean designer Jihae Kim presents a sustainable technological heating solution during harsh winters. That way you could put it directly above a busy city perhaps. The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. Obviously a water brake windmill is suited for a windy climate. Most used simple wooden blades. Prototypes of heat generating windmills, built by Esra L. Sorensen in 1974. One of these builders, Jrgen Krogsgaard, wrote a manual in the 1970s and I have asked him if it could be published. It's probably going to be less practical compared to using a water brake. So, let's say wind -> electric -> heat gives an overall efficiency of 70%. First, not all energy loss of an electrical generator is heat, there's also noise and vibration. Dozens of Danish tinkerers did in the 1970s and 1980s. Posted by: For example, here in Barcelona, it would be useless. First, thank you for putting up such an interesting web site. [8] A 2013 study using a prototype obtained similar results, and calculated the efficiency of the system to be 91%. 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. I'm not a native English speaker and I should have written "as efficient". First, thank you for putting up such an interesting web site. That said PV panels are so cheap now particularly as many people are upgrading that a simple resistance water heater does the job and probably for rather less than a heat pump. It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. kris de decker | 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. Very interesting article! [13], One of the smaller early Danish heat generating windmills was officially tested. Sure could DIY one instead from hydro power, but would be just like a prototype - not extensively tested and very efficient. 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. fell free to contact me if you have any question. ", 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. Comments are moderated and will not appear until approved by the author. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger. 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. The thing about heat pumps is that they move more heat energy than it takes to drive them. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. 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. Despite a warming climate, the demand for thermal energy is as high as ever. Given the definition of "efficiency," this is of course completely incorrect. 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. Also, designing some cavitation into the submersed rotor might increase the rate of heating. 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. The question is how does one turn the heat producing source (the windmill)on and off. However, in this case a gearbox is required to achieve optimal efficiency. Converting the stored heat into electricity is at most 30% efficient, meaning that two thirds of the wind energy is lost due to needless energy conversions -- and the same is true when solar thermal is used for power production. 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. It appears much of the ancillary apparatus could be sourced many places. I changed it into "more efficient". The researchers then ran simulations over a period of fifty hours to calculate the windmills heat output. A heat generating windmill can be combined with a solar boiler, so that both sun and wind can supply direct thermal energy using a smaller water tank. Of cause it is not economical to have that much storage. Pro Breeze Mini Heater - Ceramic Fan Heater perfect for Desks and Tables - Personal PTC Heater, White Read Review. I'll post their reply (if it comes) here in the comments section. I believe the research institute of your reference [15] - DLR (German Aerospace Centre) do have a project to build and test a prototype of this kind of system. Check Price 27% OFF. March 09, 2019 at 11:46 PM. For instance, what if you moved it to a nearby higher elevation during the summer? How to Build a Practical Household Bike Generator, The Printed Website: Volume III & The Comments. 2, A windmill with water brake built at the Institute for Agricultural Techniques in 1974. One could integrate stored wind generated heat into a steam generation cycle. 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? Posted by: 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] [8] [9], Drawing of a heating system based on a water brake windmill. 7 8 9, Image; a heating system based on a water brake windmill. 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. [15]. kris de decker | 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. There are quite a few district heating systems which use waste heat If you can afford it, a combination of both wind and solar power gives you the best of both worlds. 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. 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. 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. Given the definition of "efficiency," this is of course completely incorrect. I thoroughly enjoyed the article on heating with windmills. 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. 9 This is comparable to the efficiency of a wind turbine heating water through electricity. Mr Beams MB390 300-Lumen Weatherproof Wireless Battery Powered LED Ultra Bright Spotlight with Motion Sensor, Brown Read Review. [7] Many were built with used car parts and other discarded materials. How would it be easily replicable? Like being commercialised by high view 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. But this approach doesn't work for industry, where there's also a high demand for heat. You'll need to heat the water somehow outside the shed and run the hot water through pipes that run inside the shed. They move heat energy from outside, making an already cool outside a little colder, to inside your house making it warmer. free uk mainland delivery 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?
