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). I would believe 30% more efficient. Larger heat generating windmills were built in the 1980s. Of course, there are other ways but this is the simplest solution. And there's also hot water production for washing and cleaning. , Real-world tests of small wind turbines in Netherlands and the UK, Kris De Decker, The Oil Drum, 2010. One of these builders, Jrgen Krogsgaard, wrote a manual in the 1970s and I have asked him if it could be published. SHOP OUR RANGE OF MODULAR SHEDS NOW. Illustration: Rona Binay for Low-tech Magazine. 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. The question is how does one turn the heat producing source (the windmill)on and off. 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. Posted by: This is not about math, it's about language. Great work and service that you are providing! Like the stangenkunst that you dedicated a few articles too? How to design a sailing ship for the 21st century? Posted by: Job van der Zwan | Well, there is a great problem in that an average wind speed of 11 mps is rare.that is nearly 25mph. They conclude that a mechanical heat pump + mechanical windmill is the most cost effective realization of wind powered heating. 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. Check Price 35% OFF. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. 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? 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. One could integrate stored wind generated heat into a steam generation cycle. , erneckien, Jurgita, and Tadas dankus. 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. A gear box would help, but this adds complexity. I don't have the answer but I've sent a mail to some scientists who wrote about the eddy current heater. Could be a topic for a future article. The SCOP values in table 3 show heat pumps to have ~3x the performance of retarders or boilers (less than I claimed for GSHP, but consistent with figures I've see for air sourced heat pumps). , The Rise of Modern Wind Energy: Wind Power for the World. Very interesting article! For example how much more heat do you get when you use ground loops or ground water vs outside air? Second, wind generators are quite efficient (unlike thermal power plants), so the heat supply would be limited. 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. 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. 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. This means that less solar and wind energy converters and thus less space and resources are needed to supply a certain amount of heat. But that's because you heat people, not spaces. Again, also here things dont change much from the conventional. If you also want renewable electricity, you could use solar PV or a second windmill instead of trying to fit everything into one machine. Anyway it's not a point - end goal is to reduce our dependence on resources. This DIY solar box will work as a little solar heater for the shed and be the cheapest way of providing heat to the shed. *maybe buffered by an hour or two of battery back-up to allow some flexibility. Thanks for your speedy reply. 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. Image provided by the, Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). Given the right conditions, a mechanical windmill with an oversized brake system is a cheap, effective, and sustainable heatingsystem. 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. If not where would I find suppliers for this type of turbine? 13. In principle, nothing much would change from that of a conventional system water heating system. The Calorius type 37 which had a rotor diameter of 5 meters and a height of 9 meters produced 3.5 kilowatt of heat at a wind speed of 11 m/s (a strong breeze, Beaufort 6). So, let's say wind -> electric -> heat gives an overall efficiency of 70%. Company registered number: 7120391. Posted by: Posted by: It transferred the rotational energy from its wind rotor directly to the axis of a machine, for example for sawing wood or grinding grain. Of course, there are other ways but this is the simplest solution. There was also a "LO-RA" water brake mill. The printed archives now amount to four volumes with a total of 2,398 pages and 709 images. It's probably going to be less practical compared to using a water brake. In total, at least a dozen different models have been documented, both DIY and commercial models. 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. Purpose it serves: The box, when made successfully, will capture heat from the sunlight when kept under it for some hours. Would the amount of water in radiators be reduced or increased based on how hot or cool you'd want? The same windmill as the one pictured above, seen from below. I went looking for a source for eddy current heaters, however, and came up with nothing. All other technologies are in between. 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. 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. Third, you lose a significant cost advantage because you reintroduce all the electric components. Does anyone know of a source for where to buy a small permanent magnet eddy current heater for water or oil heating generation? https://www.highviewpower.com/technology/. But although we cannot exclude their use in pre-industrial times, the first reference to heat producing windmills dates from the 1970s, when the Danes started building them in the wake of the first oil crisis. They are in their seventies and eighties now, some of them have passed away. 13. February 28, 2019 at 11:56 AM. The simplicity of direct mechanical heat production by wind brake is alluring. 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. March 02, 2019 at 01:18 PM. Sure could DIY one instead from hydro power, but would be just like a prototype - not extensively tested and very efficient. Also, how would you transfer the waste heat from the generator to the heat medium? Consequently, hot water could literally be tapped out of the windmill. Happy to see an article related to my PhD research topic! These are comprised of a magnet mounted on a rotating shaft, and can reach temperatures of up to 600 degrees Celsius. Energy 164 (2018): 925-936. For instance, what if you moved it to a nearby higher elevation during the summer? February 28, 2019 at 12:36 AM. In short, the heat generating windmill addresses the main disadvantages of wind power: its low power density, and its intermittency. A UK based solar system could suffer from a lack of available sunshine, particularly in the winter months. Is anyone actually making the technology, or is it still in the lab? 3. The storage system is similar to that of a concentrated solar power plant (CSP), and the solar concentrators are replaced by heat generating windmills. March 05, 2019 at 10:46 AM, @kris de decker -March 01, 2019 at 08:07 PM. March 03, 2019 at 09:05 PM. Direct heat production is cheaper, can be more energy efficient, and is more sustainable than indirect heat production. Overload your circuit and it will overheat and could catch fire; go for too high a rating and youre just wasting money. On a global scale, thermal energy demand corresponds to one third of the primary energy supply, while electricity demand is only one-fifth. February 27, 2019 at 07:40 PM. Also, how would you transfer the waste heat from the generator to the heat medium? Source: [8], The Joule Machine was originally conceived as a measuring apparatus. The " how to keep a shed warm without electricity " is a guide that tells users how they can heat their sheds without using electricity. delegacioni shqiptar ne konferencen e londres; ; postnord kundtjnst flashback You'll need to heat the water somehow outside the shed and run the hot water through pipes that run inside the shed. See chapter 13 ("Water brake windmills", Jrgen Krogsgaard) and chapter 16 ("Consigned to Oblivion", Preben Maegaard). 1, The original 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. [7] Many were built with used car parts and other discarded materials. Posted by: It also features a built-in overheat protection system to prevent the heater from overheating. Walton Web Ltd 2019. luxury apartment hotels paris. 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. Water brake windmills don't need steam turbines. 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. TonyH | 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. I changed it into "more efficient". The heat medium would be work done inside the house by the electricity. However, in this case a gearbox is required to achieve optimal efficiency. 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. Image: prototypes of heat generating windmills, built by Esra L. Sorensen in 1974. Ideas anyone? The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. 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. Direct heat production is cheaper, can be more energy efficient, and is more sustainable than indirect heat production. View an alternate. Midsummer Energysupplies a range of kits for solar power, whileWind & Sunhas some good offerings for wind power. However, an old-fashioned windmill can not only provide mechanical energy, but also thermal energy. 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. Could this heat storage via water tank double as a way to store potable water? Due to how the article was structured, it sometimes seemed to argue that water brake windmills are more efficient than electric heat pumps. Even the International Energy Agency doesn't mention direct conversion of wind into heat when it presents all possible options for renewable heat production. 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: March 01, 2019 at 10:10 PM. Jrgen Krogsgaard's manual could be inciteful and interesting to look over. Taking into account both investment and operational costs, small-scale heat generating windmills with mechanical heat pumps are equally expensive or cheaper than conventional gas boilers when assuming the typical performance of a small windmill (which produces over a period of one year 12% to 22% of its maximum energy output). 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. 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. [13]. Walton Web is authorised and regulated by the Financial Conduct Authority, registration number 620773. Credit is subject to status. Could this heat storage via water tank double as a way to store potable water? If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. The result is heat generated by wind energy. All text in Danish, but Google translate is your friend! Not sure about your approach though. Source: 8. I'll post their reply (if it comes) here in the comments section. It uses a patented and innovative device called a Magnetodynamic Heater that works with magnetic induced Eddy currents to produce heat. Urban Fish Ponds: Low-tech Sewage Treatment for Towns and Cities. 15. Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. This is comparable to the heat output of the smallest electric boilers for space heating. 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. Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. 7. [8]. Theres two reasons for this. Even 'Wind Power for the World: The Rise of Modern Wind Energy' doesn't give its meaning. This is saying that direct wind to heat would then be 280% efficient. This shed heater has an insulated body that's entirely resistant to heat and features thermal insulation in the middle. Joseph | I'm not a native English speaker and I should have written "as efficient". The thing about heat pumps is that they move more heat energy than it takes to drive them. 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. HyLite. @Kris I'm not seeing the contradiction in [15]. However, using the stored heat for electricity production is considerably more costly and less sustainable compared to using heat generating windmills for direct heat production. I'm very curious to read those results, but you did not provide the link you are talking about Hi Kris - oh shoot - so sorry. 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. The LO-FA was also the largest of the heat generating windmills, with a 12 meter diameter rotor. The heater requires a specific battery or electricity to ignite the propane and run the fans that blow out the hot air. Because heat can be stored much more cheaply than electricity, a two-days storm can give heat for a week or longer. Ideas anyone? Posted by: Hopefully, direct heat production will be given the priority it deserves. Runner-up space heater: Vornado AVH10. 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. 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. , Cao, Karl-Kin, et al. It's probably going to be less practical compared to using a water brake. Happy to see an article related to my PhD research topic! Read Review PK Green Check Price 2 It works like this: the cans are painted black to better absorb heat, and then holes are drilled in the bottom to allow air to flow through them. It was found that the torque-speed characteristics of wind rotor and impeller should be carefully matched to achieve maximum efficiency. HeadakusMaximus | Logan | In terms of using wind-driven mechanical heat pumps to produce heat. 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. March 11, 2019 at 11:35 AM, Hi Kris - oh shoot - so sorry. Wind Talk Space Heater for Indoor Use, 1500W Electric Oscillating Portable Ceramic Tower Heater with Remote . 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. [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. Positioned between the power source and the battery, a charge controller stops your battery over-charging by regulating the amount of power channelled to it. That's also an interesting idea, and it could be more practical than what Job proposes. Sure could DIY one instead from hydro power, but would be just like a prototype - not extensively tested and very efficient. Keeping Some of the Lights On: Redefining Energy Security | Key Features: Choice of three heating settings: 30W (fan only), 1500W, and 3000W Integrated, adjustable thermostat control (0-850) 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. A direct mechanically coupled heat pump may not be as efficient as it sounds. 1 15. Davide Honey | Cao, Karl-Kin, et al. Radiators are usually controlled by temperature thermostats preset to the desired temperature for each room. I did not look into wind powered cooling but it could be possible. Furthermore, the friction liquid in the water brake was not water but hydraulic oil, which can be heated up to much higher temperatures. Mario Stoltz | So, let's say wind -> electric -> heat gives an overall efficiency of 70%. FREE delivery Mon, Feb 20 . Create hole for intake and exhaust hoses. I changed it into "more efficient". March 03, 2019 at 01:04 PM. 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. To work out the power rating of your inverter, simply add up the required wattage of all the equipment youll be using. Still, thanks for expanding our horizon of the possible! Source: [13]. Its heat output was estimated to be 90 kilowatt at a wind speed of 14 m/s (Beaufort 7). They can be ordered inour Lulu bookstore. We are designing the device specifically for the needs of Newfoundlander and for that we want your input. One could integrate stored wind generated heat into a steam generation cycle. what it has going for it is a large volume of water in an insulated box . 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. 5 6. To work out the power rating of your inverter, simply add up the required wattage of all the equipment you'll be using. Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels. 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. Posted by: I'll keep you updated here in the comments section. 16 In these systems, the generated heat is converted to electricity by the use of a steam turbine. ", erneckien, Jurgita, and Tadas dankus. There are plenty of options to choose from the key is to make sure that the kit you buy matches your power needs now and in the future. In the meantime, if anyone else has more info, feel free to share it. 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. If in doubt, contact them directly for advice. The SCOP values in table 3 show heat pumps to have ~3x the performance of retarders or boilers (less than I claimed for GSHP, but consistent with figures I've see for air sourced heat pumps). If you also want renewable electricity, you could use solar PV or a second windmill instead of trying to fit everything into one machine. I wonder, if heat-generating windmills allow lightweight windmills to be economical, would that mean that they could also be portable? . Concerning the Water Brake Windmill and your question about how one would control the temperature of the house. ", (note: 3x AS efficient is not the same as 3x MORE efficient). Lava Heat Italia CAPRI-A-LINE-6MPB Propane Heater$1,010. Posted by: Installing a 20,000L tank is a significant expense, but might be worth it in areas with intermittent access to water or drought conditions. [9] This is comparable to the efficiency of a wind turbine heating water through electricity. This article is amazing and I love the idea of this. Due to friction among molecules of the water, mechanical energy is converted into heat energy. They require simple materials: wood and/or metal. Would the heat be sufficient to kill pathogens in the water tank for longer-term water storage? Another model could be to run an air compressor from the turbine. September 28, 2020 at 10:19 PM. Despite a warming climate, the demand for thermal energy is as high as ever. https://www.highviewpower.com/technology/. 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. Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. A solar thermal collector skips the conversion to electricity and supplies renewable thermal energy in a direct and more efficient way. One option is to use source heat that does not have to be maintained and a storage tank. Posted by: It makes so much sense. Photo by Claus Nybroe. What steam turbine? Posted by: [15]. Fourth International Conference on Environmental and Computer Science (ICECS 2011), Singapore, Sept. 2011. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). fake by any means necessary jacket. Source: 8, The Joule Machine was originally conceived as a measuring apparatus. Main 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. 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? Also say you've got the 20 mph wind consistent enough to sustain the power output. Does anyone know of a source for where to buy a small permanent magnet eddy current heater for water or oil heating generation? I think that moving the electric generator inside is the worst of both worlds. 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. They move heat energy from outside, making an already cool outside a little colder, to inside your house making it warmer. Has anyone out there done any experimentations of their own? Question I have is: Does anyone, any companies make these devices for sale? 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.
