To work out the power rating of your inverter, simply add up the required wattage of all the equipment you'll be using. In the meantime, if anyone else has more info, feel free to share it. Paint can with high heat paint. To work out the power rating of your inverter, simply add up the required wattage of all the equipment youll be using. 10. "Direct conversion of wind energy into heat using joule machine." "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." If oil or pressurised water could be used as the brake fluid, then much higher temperatures could be achieved. 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. What about adding thermoelectric generators to the set-up to generate some electricity for low current devices? ". "WIND POWERED THERMAL ENERGY SYSTEMS (WTES)". For example in the UK, heat counts for almost half of total energy use. 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. Check Price 35% OFF. 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. Mr Beams MB390 300-Lumen Weatherproof Wireless Battery Powered LED Ultra Bright Spotlight with Motion Sensor, Brown Read Review. The hydrodynamic retarder is well known as a brake system in heavy vehicles. In general, the higher the tower, the more power the wind system can produce. A heat generating windmill can also be combined with a solar boiler, so that both sun and wind can supply direct thermal energy using a smaller water tank. Dozens of Danish tinkerers did in the 1970s and 1980s. 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. 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. Kris De Decker | This shed heater has an insulated body that's entirely resistant to heat and features thermal insulation in the middle. The only commercial model once made is not for sale anymore. Sure could DIY one instead from hydro power, but would be just like a prototype - not extensively tested and very efficient. You can follow this conversation by subscribing to the comment feed for this post. 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. Subject: To build a water brake windmill from scratch. Furthermore, direct heat generation greatly improves the economics and the sustainability of smaller types of windmills. I see a few problems with your approach. I went looking for a source for eddy current heaters, however, and came up with nothing. If your shed is located in a very shady position, then the lack of sunshine even on bright days could limit the amount of electricity generated. [7]. 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. Of cause it is not economical to have that much storage. , Okazaki, Toru, Yasuyuki Shirai, and Taketsune Nakamura. If you need to plug in a computer and mobile phone, the inverter would need a continuous power rating of 150W + 600W = 750W. Obviously a water brake windmill is suited for a windy climate. 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. How would it be easily replicable? 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. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger. 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. Toby | Purely for the sake of exploring ideas I will pursue my original train of thought anyway ;). Posted by: These seem to be the only English language documents on Danish water brake windmills. We receive very little for any exported power so self-consumption is preferred. Illustration: Rona Binay for Low-tech Magazine. Could be a topic for a future article. 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. 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. The storage system is similar to that of a concentrated solar power plant (CSP), and the solar concentrators are replaced by heat generating windmills. 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. Purely for the sake of exploring ideas I will pursue my original train of thought anyway ;). The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. They are quite inefficient but 13. The system is functionally designed to create and retain heat so would need quite a few modifications to also act as a cooler. Direct heat production is cheaper, can be more energy efficient, and is more sustainable than indirect heat production. 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). Mario Stoltz | 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. 16 In these systems, the generated heat is converted to electricity by the use of a steam turbine. I think that moving the electric generator inside is the worst of both worlds. 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. 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. Build a large box with six sections with a sheet of plywood and 11 wood strips. It is much more practical to use solar thermal. A heat generator based on this principle is basically a wind-powered mixer or impeller installed into an insulated tank filled with water. Larger heat generating windmills were built in the 1980s. 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. Different types of direct and indirect heating production compared. February 27, 2019 at 11:45 PM. Also, could you reverse the process to cool a house? Furthermore, the friction liquid in the water brake was not water but hydraulic oil, which can be heated up to much higher temperatures. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). Keeping Some of the Lights On: Redefining Energy Security | kris de decker | 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. 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. In particular, the electric heat pump is promoted by many governments and organisations as a sustainable solution for renewable heat generation. Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels. They require simple materials: wood and/or metal. Again, also here things dont change much from the conventional. If you can afford it, a combination of both wind and solar power gives you the best of both worlds. No. I thoroughly enjoyed the article on heating with windmills. 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. , Cao, Karl-Kin, et al. In terms of using wind-driven mechanical heat pumps to produce heat. Obviously a water brake windmill is suited for a windy climate. Taking your shed off-grid is simple to achieve, good for the environment, and could save money in the long-term. 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. kris de decker | When I asked about anyone out there doing any experimentations of their own, I was thinking more about your "readers" than the Danish tinkerers. Hybrid power systems can provide reliable off . All Rights Reserved. Even 'Wind Power for the World: The Rise of Modern Wind Energy' doesn't give its meaning. However, solar and wind energy can also be used in a direct way, without converting them to electricity first and of course the same applies to biomass. 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. February 28, 2019 at 12:20 AM. Greenhouse, Dog House, Shed, Gable, Attic. 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. Please try again. Energy 164 (2018): 925-936. 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. Question I have is: Does anyone, any companies make these devices for sale? A UK based solar system could suffer from a lack of available sunshine, particularly in the winter months. As for what you could actually expect from running a wind turbine directly to a room heater, the answer is: trouble. I'll keep you updated here in the comments section. All other technologies are in between. Main This is saying that direct wind to heat would then be 280% efficient. Also on a larger scale, I think it makes more sense to have heat generating and electricity generating windmills standing alongside each other, rather than combining them into one machine. Posted by: The study referenced in note 15 contradicts your claims. Heat generating windmills are also investigated for renewable electricity production, mainly because they offer a better solution for energy storage compared to batteries or other common technologies. 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. For example, here in Barcelona, it would be useless. 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. The lower 10 meters of the 20 meter high tower were filled up with 15 tonnes of water in an insulated reservoir. Storing the high heat underground in rocks seems like a cheap option. 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. Brendan Howell | Create hole for intake and exhaust hoses. Very interested in this concept. ben.ben0911@gmail.com, Posted by: Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. But this approach doesn't work for industry, where there's also a high demand for heat. The system is functionally designed to create and retain heat so would need quite a few modifications to also act as a cooler. 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). 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. We are designing the device specifically for the needs of Newfoundlander and for that we want your input. The simplicity of direct mechanical heat production by wind brake is alluring. That's also an interesting idea, and it could be more practical than what Job proposes. Posted by: . Well, there is a great problem in that an average wind speed of 11 mps is rare.that is nearly 25mph. Like being commercialised by high view power. Because high temperatures are needed to produce electricity efficiently with a steam turbine, these systems cant make use of joule machines or hydrodynamic retarders, but instead rely on a type of retarder called an eddy current heater (or induction heater). BTW, I am off grid, and do have practical experience. 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. 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. A gear box could switch between heating and cooling modes. All other technologies are in between. The heater requires a specific battery or electricity to ignite the propane and run the fans that blow out the hot air. Very interesting article! The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. Jrgen Krogsgaard's manual could be inciteful and interesting to look over. 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. Most used simple wooden blades. Error type: Your comment has been saved. Join our email club Photo by Claus Nybroe. 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. 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. No. 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. Posted by: Would the heat be sufficient to kill pathogens in the water tank for longer-term water storage? I absolutely hate the "new" math illiteracy. Beneath a critical wind speed, the compressor will lack the rotational speed to compress the heat transfer fluid back to liquid. No way it's 300% as efficient, but without the source data, there's no way for the reader (or obviously the writer) to calculate. Free delivery to most postcodes. Kris De Decker | | Low-tech Magazine: The Printed Website . This is saying that direct wind to heat would then be 280% efficient. Its heat output was estimated to be 90 kilowatt at a wind speed of 14 m/s (Beaufort 7). 3. Lava Heat Italia CAPRI-A-LINE-6MPB Propane Heater$1,010. Efficiency = (work output) / (work input), "it would be three times more energy efficient compared to first converting the energy to electricity, and then back to rotational energy. The conclusion says that coupling a wind turbine to a heat pump is the most cost effective realization of wind powered heating. Also, designing some cavitation into the submersed rotor might increase the rate of heating. March 01, 2019 at 06:23 PM. "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. luxury apartment hotels paris. Or fastest delivery Fri, Feb 17 . Or they could be fabricated locally. [2], A water brake windmill built at the Institute for Agricultural Techniques in 1974. A Calorius windmill producing up to 4 kW of heat. All text in Danish, but Google translate is your friend! Are there tables out there that specify what house area can be heated to what temperature differential at what wind speeds? https://www.highviewpower.com/technology/. 7, Further into the 1980s, Knud Berthou built the most sophisticated heat generating windmill to date: the LO-FA. Davide Honey | It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. Posted by: March 03, 2019 at 01:37 PM. Press the space key then arrow keys to make a selection. 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. Bruno | First, not all energy loss of an electrical generator is heat, there's also noise and vibration. Generate storable heat during off-peak hours. [15]. Water brake windmills don't need steam turbines. And more efficient. I think this technology could be great for island communities in higher latitudes. Some chose the indirect path, converting wind generated electricity into heat using electric heating appliances. 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. The letters and numbers you entered did not match the image. 2. Source: 13. How would the economics or environmental considerations be affected if you were to move a lightweight windmill during the course of the year, in order to have windmill spend most of its time where the wind is blowing or the climate is cold? What steam turbine? 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. Lathechuck | 15. The researchers explain and illustrate the workings of the water brake windmill, and calculate the optimal performance of the technology. Kris - thanks a lot for this great article, very inspiring! Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. 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. Local heating can also be combined with direct heat production, and then you win even more. Because heat can be stored much more cheaply than electricity, a two-days storm can give heat for a week or longer. For example, you could build a desk or a bench with water pipes inside, heated by a small mechanical windmill and heat storage. 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. Image: prototypes of heat generating windmills, built by Esra L. Sorensen in 1974. However, in the LO-FA windmill all mechanical parts for energy conversion were moved to the top of the tower. Updated On Feb 2023 711 Reviews Studied By Customer Ratings Affiliate Disclosure 1 COMLIFE PTC 900W/1800W Ceramic Space Heater,Electric Mini Personal Heater Fan With Rotation Function,Over-Heat And Tip-o. Anyway it's not a point - end goal is to reduce our dependence on resources. A solar thermal collector skips the conversion to electricity and supplies renewable thermal energy in a direct and more efficient way. , Chakirov, Roustiam, and Yuriy Vagapov. 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. 7- DIY Solar Panel Air Heater Another ingenious design that enable you to build a solar garage heater using recycled soda cans. This article is amazing and I love the idea of this. There is much more to win on the demand side than on the supply side, and the habit to heat the whole space of a building can indeed be questioned. 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). I changed it into "more efficient". 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. Seems like they suffered from mechanical and plumbing trouble, probably related to the fact that the system was basically a semi-prototype. The thing about heat pumps is that they move more heat energy than it takes to drive them. A gear box would help, but this adds complexity. The most fascinating thing about water brake windmills is that, hypothetically, they could have been built hundreds or even thousands of years ago. Efficiency = (work output) / (work input), "it would be three times more energy efficient compared to first converting the energy to electricity, and then back to rotational energy. Posted by: It's probably going to be less practical compared to using a water brake. fell free to contact me if you have any question. In total, at least a dozen different models have been documented, both DIY and commercial models. 4, 2013, Joules experiment: An historico-critical approach, Marcos Pou Gallo Advisor. According to Eco-shed of the Year winner. Image: A Calorius windmill producing up to 4 kW of heat. > Does anyone, any companies make these devices for sale? I am curious about the potential for a hybrid wind turbine (clutchable): Generate electricity during peak hours (high price) Having trouble reading this image? 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. From 1993 to 2000, the Danish firm Westrup built a total of 34 water brake windmills based on this design, and by 2012 there were still 17 in operation. Even the International Energy Agency doesn't mention direct conversion of wind into heat when it presents all possible options for renewable heat production. For example how much more heat do you get when you use ground loops or ground water vs outside air? 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? If not where would I find suppliers for this type of turbine? The result is heat generated by wind energy. It's mechanical windmills with mechanical heat pumps that are more energy efficient (and cheaper) than wind turbines with electrical heat pumps. 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? It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. The EcoFlow DELTA kit with two 160w solar panels supplies all the power you need for a smaller shed. Kris De Decker | Obviously, its not always stormy weather, which means that the average wind speed is at least as important. March 01, 2019 at 08:07 PM. The hot water is stored in a tank. Of cause it is not economical to have that much storage. ", 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. Hot Water Pipes. "Does anyone, any companies make these devices for sale?"". "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. Installing a 20,000L tank is a significant expense, but might be worth it in areas with intermittent access to water or drought conditions. Consequently, the heat generating windmill is at its best as a decentralised energy source, providing heat to an off-the-grid household or in the optimal case a relatively small town or city, or an industrial area. To convert the 12V DC current from your battery bank, you need to route the electricity from the battery through an inverter, which converts the power to AC. "Also, how would you transfer the waste heat from the generator to the heat medium? 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. Erik | For the moment, there's no other option than to build a water brake windmill from scratch. Due to how the article was structured, it sometimes seemed to argue that water brake windmills are more efficient than electric heat pumps. March 11, 2019 at 11:35 AM, Hi Kris - oh shoot - so sorry. kris de decker | It transferred the rotational energy from its wind rotor directly to the axis of a machine, for example for sawing wood or grinding grain. It's cheaper than my oil fired neighbours, 100% carbon free and practical for many people to install now. I'll post their reply (if it comes) here in the comments section. That way it would be kept simple. Obviously not everyone has space for a heat generating windmill, but there's no need to put a windmill next to each house. It was found that the torque-speed characteristics of wind rotor and impeller must be carefully matched to achieve maximum efficiency. Propane Heater, thermomate 18,000 BTU Portable LP Gas Heater with 3 Power Settings, Mobile Radiant Cabinet LP Heater with Gas Regulator and Hose, Heating Area Up to 450 Sq. Russ Mattson | Once you place the box inside your shed, it will transfer the captured heat through holes. Due to efficiency heatpumps are intermittent energy demand. How to Build a Practical Household Bike Generator, The Printed Website: Volume III & The Comments. They can be ordered inour Lulu bookstore. Company registered number: 7120391. Purpose it serves: The box, when made successfully, will capture heat from the sunlight when kept under it for some hours. 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. Even while distributing a large amount of heat, the Mr. Heater Hero stays cool to the touch. A solar thermal collector skips the conversion to electricity and supplies renewable thermal energy in a direct and more efficient way. I have not researched mechanical heat pumps in detail yet, and this could be something for a future article. [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. 2) Open fireside BBQ grill with charcoal. what it has going for it is a large volume of water in an insulated box .
