July 14, 2021 at 01:32 AM. Compression will give you a heater, and then releasing the compressed air will give you cooling. Erik | March 01, 2019 at 07:46 PM. February 28, 2019 at 11:56 AM. The only commercial model once made is not for sale anymore. Even while distributing a large amount of heat, the Mr. Heater Hero stays cool to the touch. Has anyone out there done any experimentations of their own? 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). We are in Perth in Western Australia. 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. The Joule is defined as the energy equivalent to the work done by a force of 1 Newton over a distance of 1 meter, i.e. It's mechanical windmills with mechanical heat pumps that are more energy efficient (and cheaper) than wind turbines with electrical heat pumps. Low-tech Magazine underscores the potential of past and often forgotten technologies and how they can inform sustainable energy practices. 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. Posted by: The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. But this approach doesn't work for industry, where there's also a high demand for heat. ". I did not look into wind powered cooling but it could be possible. So I experimented a bit toward creating more concentrated heat at a high temperature. Installing cables of the correct rating is essential. No idea what "LO-FA" stands for. 7 Many were built with used car parts and other discarded materials. 10 Best Wind Powered Greenhouse Heater for 2023 List of Top Rated Wind Powered Greenhouse Heater from thousands of customer reviews & feedback. to receive exclusive offers and discounts. It makes so much sense. Posted by: 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. Thanks for your speedy reply. No reviews. Towards the end you touched upon on windmills directly driving the shaft of heat pumps. 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. Storing the high heat underground in rocks seems like a cheap option. I absolutely hate the "new" math illiteracy. 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. Main Menu 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. 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. , erneckien, Jurgita, and Tadas dankus. It's probably going to be less practical compared to using a water brake."". These seem to be the only English language documents on Danish water brake windmills. Show sites now open. delegacioni shqiptar ne konferencen e londres; ; postnord kundtjnst flashback In terms of using wind-driven mechanical heat pumps to produce heat. Purpose it serves: The box, when made successfully, will capture heat from the sunlight when kept under it for some hours. March 09, 2019 at 11:46 PM. 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. How to Build a Practical Household Bike Generator, The Printed Website: Volume III & The Comments. Due to friction among molecules of the water, mechanical energy is converted into heat energy. 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. I thoroughly enjoyed the article on heating with windmills. 7. Local heating can also be combined with direct heat production, and then you win even more. [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. Kris De Decker | kris de decker | 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. [12] However, using similar models for heat production can decrease embodied energy and costs, increass lifetime, and improve efficiency. [5] [6]. Kris - thanks a lot for this great article, very inspiring! Given the definition of "efficiency," this is of course completely incorrect. So, let's say wind -> electric -> heat gives an overall efficiency of 70%. For instance, what if you moved it to a nearby higher elevation during the summer? The Joule Machine has lower weight, smaller size, and lower costs than an electrical generator. They require simple materials: wood and/or metal. Anthony | Mechanical windmills are less complex, which makes them more affordable and less resource-intensive to build, and which increases their lifetime. Others, however, developed mechanical windmills that produced heat directly. Simply enter your email address and click Join. If in doubt, contact them directly for advice. Using eddy current heaters, windmills could provide direct heat at higher temperatures, making their potential use in industry even larger. All Rights Reserved. "Usage of the Wind Energy for Heating of the Energy-Efficient Buildings: Analysis of Possibilities." Main Posted by: Obviously a water brake windmill is suited for a windy climate. 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. 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. [Update: just received a mail that the author, who built one of the first water brake mills, is busy answering my questions -- more soon], Posted by: 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. According toWhich, while micro roof-mounted wind turbines are cheaper, theyre also less efficient and will produce a lot less electricity than pole-mounted ones. 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? The letters and numbers you entered did not match the image. Of course, there are other ways but this is the simplest solution. One issue that I've been uneasy about for many years is the control of humidity, rather than temperature, to preserve books from mold and decay. They are quite inefficient but 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. Hopefully, direct heat production will be given the priority it deserves. 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. Or is it just controlling the flow rate of the water? Posted by: 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. Subject: To build a water brake windmill from scratch. The most fascinating thing about water brake windmills is that, hypothetically, they could have been built hundreds or even thousands of years ago. They conclude that a mechanical heat pump + mechanical windmill is the most cost effective realization of wind powered heating. Larger windmills have higher capacity factors (16-40%), which result in even larger cost savings. Most turbine manufacturers provide wind energy system packages that include towers. Davide Honey | Panels fitted to a roof can be neat and unobtrusive, unlike the more obvious presence of a wind turbine. Davide Honey | BTW, I am off grid, and do have practical experience. OK, now I get your point, you are right. Nitto, Dipl-Ing Alejandro Nicols, Carsten Agert, and Yvonne Scholz. If more information is needed maybe we could pool our resources and help one another to gather information for a Proto build. The best oil-filled radiator heater: De'Longhi TRD40615T. Electricity produced by renewable energy sources can be and is being converted to heat in an indirect way. Renewable energy production is almost entirely aimed at the generation of electricity. Toby | what it has going for it is a large volume of water in an insulated box . Renewable energy 83 (2015): 332-338. I just wanted to comment in relation to the article and the use of heat pumps. January 05, 2023 at 07:29 PM. 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, four volumes with a total of 2,398 pages and 709 images, https://en.wikipedia.org/wiki/Heat_pump_and_refrigeration_cycle#Gas_cycle, https://asmedigitalcollection.asme.org/energyresources/article/144/4/040802/1120767/State-of-the-art-of-Windthermal-Turbines-A. Keeping Some of the Lights On: Redefining Energy Security | 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. I think they are claiming a round trip efficiency of 60% for electricity storage. clifdweller | Another model could be to run an air compressor from the turbine. Wood stoves equipped with thermoelectric generators can produce electricity that is more sustainable, more reliable, and less costly than power from solar PV panels. At the time, Denmark was almost entirely dependent on imported oil for heating, which left many households in the cold when the oil supply was disturbed. BEST SOLAR VENT: Master Flow 500 CFM Solar Powered Roof Mount Exhaust. Some exclusions apply. Posted by: 14. It all seems to be an interesting concept, but "proof of concept" and "worth doing" are very different. This means that less solar and wind energy converters and thus less space and resources are needed to supply a certain amount of heat. 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). But that's because you heat people, not spaces. Local heating can also be combined with direct heat production, and then you win even more. 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. 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. There are quite a few district heating systems which use waste heat These panels can be sited either on the ground nearby, or on the shed roof itself. 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. In terms of using wind-driven mechanical heat pumps to produce heat. In short, the heat generating windmill addresses the main disadvantages of wind power: its low power density, and its intermittency. 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 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). Posted by: May 04, 2019 at 06:52 PM. Very interesting article! 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. Tests have shown that small wind turbines producing electricity are very inefficient and dont always generate as much energy as was needed to produce them. 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). The simplicity of direct mechanical heat production by wind brake is alluring. "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. Larger heat generating windmills were built in the 1980s. 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. 2) Open fireside BBQ grill with charcoal. Happy to see an article related to my PhD research topic! The plan is for a passive heater made with soda cans, an old window, and some insulation. HyLite. ijk_ijk | A gear box could switch between heating and cooling modes. What about adding thermoelectric generators to the set-up to generate some electricity for low current devices? 1. Or they could be fabricated locally. "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." I did not look into wind powered cooling but it could be possible. Charles | Would the amount of water in radiators be reduced or increased based on how hot or cool you'd want? 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. A direct mechanically coupled heat pump may not be as efficient as it sounds. Key Features: Choice of three heating settings: 30W (fan only), 1500W, and 3000W Integrated, adjustable thermostat control (0-850) Want to get off-grid power in your shed? For example how much more heat do you get when you use ground loops or ground water vs outside air? However, we use more energy in the form of heat, which solar panels and wind turbines can produce only indirectly and relatively inefficiently. I built a water brake using a paint can and spun it with my drill press. TonyH | 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. It's probably going to be less practical compared to using a water brake. I would love to learn more about the feasibility of those mills as heating system for small houses. Are there tables out there that specify what house area can be heated to what temperature differential at what wind speeds? Posted by: With 6 AC outlets and many ports, you can power up to 13 devices simultaneously. 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. Almost nobody knows that a windmill can produce heat directly. Third, you lose a significant cost advantage because you reintroduce all the electric components. A 2013 study using a prototype calculated the efficiency of the system to be 91%. Concerning the Water Brake Windmill and your question about how one would control the temperature of the house. I wonder how practical a windmill brake heater would be if you replaced the steam turbine with a stirling engine? 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. "Concept study of wind power utilizing direct thermal energy conversion and thermal energy storage." 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. A solar thermal collector skips the conversion to electricity and supplies renewable thermal energy in a direct and more efficient way. On the other hand, the cable that runs between the power source and the battery is expensive and may limit how far away from your shed you can install a pole mounted turbine. The use of direct solar heat and geothermal heat provide less than 1% and 0.2% of global heat demand, respectively 4 5. Another model could be to run an air compressor from the turbine. kris de decker | 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. Like the stangenkunst that you dedicated a few articles too? 15. [8]. Kris De Decker | I think they are claiming a round trip efficiency of 60% for electricity storage. I see a few problems with your approach. Not very elegant but it works for us. 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. Water brake windmills don't need steam turbines. Like a joule machine, it converts rotational energy into heat without the involvement of electricity. The hydrodynamic retarder is well known as a brake system in heavy vehicles. Posted by: March 03, 2019 at 07:52 PM. The system is functionally designed to create and retain heat so would need quite a few modifications to also act as a cooler. Different types of direct and indirect heating production compared. The printed archives of Low-tech Magazine now amount to four volumes with a total of 2,398 pages and 709 images. We are designing the device specifically for the needs of Newfoundlander and for that we want your input. , Chakirov, Roustiam, and Yuriy Vagapov. 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. "Has anyone out there done any experimentations of their own?"". The trick here is to turn the lower heating element to a much higher setting than you would the upper heating element. This adds back an electric generator to the system but it only has to be sized for average power*, not peak windy day power, What if We Replace Guns and Bullets with Bows and Arrows? Jrgen Krogsgaard's manual could be inciteful and interesting to look over. And more efficient. September 02, 2019 at 06:36 PM. The heater requires a specific battery or electricity to ignite the propane and run the fans that blow out the hot air. But this approach doesn't work for industry, where there's also a high demand for heat. Image: Water brake windmill developed by O. Helgason (left), water brake with variable load system (right). The mill was built by Jorgen Andersen in 1975, and stood in Serritslev. The LO-FA was also the largest of the heat generating windmills, with a 12 meter diameter rotor. 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. [15]. Posted by: View an alternate. Even the International Energy Agency doesn't mention direct conversion of wind into heat when it presents all possible options for renewable heat production. In practice I heat my home and hot water with a heat pump powered by renewable electricity, with a bit of solar thermal boost. For the moment, there's no other option than to build a water brake windmill from scratch. Question I have is: Does anyone, any companies make these devices for sale? "", Fair points. Or would it be better to generate e-power all the time if the turbine is capable of it? , Real-world tests of small wind turbines in Netherlands and the UK, Kris De Decker, The Oil Drum, 2010. Posted by: Your comment has not yet been posted. The problem is that almost nobody knows this. Much simpler, less material (i.e. BVG Group Ltd. Walton Web Limited is acting as a credit broker offering finance products from Omni Capital Retail Finance Limited. 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 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. According to Eco-shed of the Year winner. I just wanted to comment in relation to the article and the use of heat pumps. 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. February 28, 2019 at 09:36 PM. Larger heat generating windmills were built in the 1980s. If not where would I find suppliers for this type of turbine? March 11, 2019 at 11:35 AM, Hi Kris - oh shoot - so sorry. 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. 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. 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. Its heat output was estimated to be 90 kilowatt at a wind speed of 14 m/s (Beaufort 7). I think that moving the electric generator inside is the worst of both worlds.
