Wind energy

solution
Setup multiple VAWT or HAWT connected each to an air compressor channeling the wind to stacked modular steel containers(fire extinguisher) as per Air Engine description. This way you only use a single Alternators commercial units and not the DIY hacked versions on YouTube with copper coils, neodymium magnets and epoxy glue, or at least you would only need to share one such alternator between ten turbines. Air compressors are freely available and their parts obtainable. The modular containers release their compressed air in parallel through the exhaust nozzle into a turbo charger(vehicle) compression side, which is where the alternator is connected for on demand electricity production. Hot air exhaust gas is vented on the turbine side. Idea for air compressor https://www.youtube.com/watch?v=CThCUDddvFM

By heating the compressed air over Storenergy.rs ceramic balls heated with solar heliostats, the effective energy yield is orders of magnitude larger than only a wind solution. Solar and wind energy is soaked up during the day and merged for high energy intensive applications at night. Connect thousands of these units across the country to the grid, wheeling the power to where it is needed using smart meters.

Horizontal Axial flow Turbine
https://www.youtube.com/watch?v=EPmW-BjCiWI by James Biggar Plans for this project are available here: https://www.resystech.com/3-kw-wind-turbine.html for the 3m 3kwh version.(Mod the design, extending the blades to 5m and the power is 5kw). In this video I build and install the 3 kW Reaper wind turbine. I know it's long, so I posted some time stamps in the comments below to help you navigate to the parts that might interest you. This is a super efficient wind turbine with a 12 ft (3.7 m) diameter rotor driving two 12 coil/16 pole axial flux permanent magnet generators to eliminate the cogging resistance that's inherent in so many radial flux designs, and it has a power potential of 3 kW in a ~30 mph wind stream. In an area with a mean annual wind speed of 11 mph (5 mps) or higher, this turbine will produce 500 kWh+ of energy every month, nearly enough to take an avg home completely off the grid. https://www.youtube.com/watch?v=9FxT-Nyc2tI     This is the trailer for the upcoming video series about my homemade wind generator that I built in 2020/2021. The next videos will be uploaded when I have edited them. I will link them here as soon as they are ready!

The new wind turbine was developed under a partnership with the City University London, based on a patented, low cost technology developed by the University called the Passive Air-jet Vortex Generator. The high-efficiency aerodynamics enable the turbine to operate at lower speeds, which presumably would help mute the any noise. More to the point, Totempower’s goal is to make wind turbine ownership as simple as owning any other standard home energy device such as a furnace or hot water heater. Testing at the University is under way and the company hopes to secure financing to bring two models into production by 2012 – a smaller model for individual homes and a larger one for commercial facilities or community power generation.

https://www.youtube.com/watch?v=g_H2PQ9mZ3k About 4 years ago now i made a VAWT and it sat under my bench for years, recently i pulled it out and tested it in some strong wind. The results were disappointing. The alternator was working great but the wing design was just to inefficient. The next day i flipped it on its side and made a tail for it. I then did alot of reading on blade carving and carved some 1.6m blades.

Solution 1
Combine the Honeywell design with the brim cone design - Wind_energy from Japan or the Ogin shroud design(Wind_energy) and attach to planetary gearbox constructed with techniques from Machine design. Honeywell's blades remains at the same speed in excessive winds. A brim or circular shroud around a traditional three bladed setup doubles the output power by creating a low pressure pocket and thus higher pressure differential. Invented by Prof. Yuji Ohya from Kyushu University. https://www.youtube.com/watch?v=RAO3mVbGqrI,    Ohya patents and see Grunfos wind turbines.

South-African unemployed people whom Honeywell cannot in effect sue(cannot go to jail for civil debt), manufactures the parts for kit assembly using Heated chamber 3d printing(design Patents hacked from Stratasys) and ships the individual parts accepting Bitcoin as payment. Proper Encryption prevents the surveillance-industrial-complex NSA from informing Honeywell and intercepting the shipments to international customers.(once a year the NSA shares all the trade secrets, phone transcripts etc. with the top 500 US companies under the misdirection of a 'cyber security seminar'. Cyber security is just a cover for the real purpose: revealing intercepted trade secrets. this is part of the nsa funding model.)

Honeywell wind turbine(sol2)
Blade tip power system purchase ,strip apart, HackPatents and upload design to internet. The blades actually reduce the speed if the wind goes above a certain speed, preventing the system from being damaged while still generating electricity. Other systems have to let the blade free-wheel proportional to the wind force in order to prevent mechanical damage to the system. TAM Wind Turbine uses a system of magnets and stators surrounding its outer ring, capturing power at the blade tips where speed is greatest. An alternative is to mount a planetary gearbox radially and centrally, but this will need a stronger support structure. Torrent site.

Solution 3
Attach a small plantery gearbox to windmill. Gears are made on 4 axis Lathe with Gears_robot broaching, Metal casting and Sand casting. All tall commercial wind systems work on the planetary gearbox principle. The high speed end rotates a generator, this is preferred over an axial generator setup(circular arrangement of magnets) implemented by DIY hobby solutions. Also such planetary design has many expired patents. https://www.google.com/patents/US8393994 (sun gear).

Vertical turbine
Cut blade out of styrofoam with 4 axis mill for Metal casting or form shape on anvil. https://www.youtube.com/watch?v=a3n-VBpcqzM Gorlov helical turbine  Generates the least noise pollution, probably the most important factor to consider with a residential setup. http://www.ugei.com/vertical-axis-wind-turbine/visionair3-vawt The design can easily be hacked by printing it in a 3d Heated chamber and and casting it out of aluminum using the 3d_printers http://www.lynxwind.com/gull-wind-turbines.html He has been mainly focused on the VAWT as they spin around vertically and never have to be pointed into the wind in order to start rotating. They are also very silent when they operate and do not need a lot of wind to start rotating. The smallest breeze can start generating power regardless of how small the energy output is. If the wind increases to high speeds, this type of wind generator is not affected it keeps on turning and generating energy from the wind. Most traditional wind turbines require a certain wind speed to start turning due to the fact that the alternators often get clogged. This happens when the the magnets get attracted to the steel laminates within the alternator. Marcus’s design does not have steel laminates, so the magnets have nothing to get attracted to. http://windgeneratorstoday.com/lynx-wind-turbines/ http://www.arborwind.com/ http://www.superturbine.net/ http://www.windpowermonthly.com/article/1124462/quirky-wind-designs-become-mainstream links to various designs

Energy ball
http://www.homeenergy.se/ Fans ball The “Energy Ball”, a product from the Netherlands which is also sold in the neighbouring country of Belgium. The windmill is made by a company named “Home Energy” (read a snippet of their website in English, French and Swedish). Energy_ball_urban_windmillThe Energy Ball, which can be placed on a roof or on a mast in the garden, is said to deliver more energy than a traditional windmill, and to generate electricity at a very low wind speed of 2 metres per second (Beaufort 2). The secret of these results is the “Venturi-effect”, inspired by river currents. Thanks to the “unusual and exceptional aerodynamic characteristics”, the machine creates a wind flow pattern that “converges first and is then accelerated through the rotor”. Furthermore, Home Energy labels the Energy Ball as "beautiful" and "noiseless", addressing two important objections against urban windmills: noise pollution and visual intrusion.

sheerwind
powerpod same type of concept takes wind from any direction and compresses it with venturi. Most efficient design is the Sheerwind venturi(4x) tube(patented), stacked with three turbines inside the tube. The blades are the Honeywell(Windtronics) design which automatically cuts the rotation speed when the wind exceeds the operating limit. James Biggar turbine which rotates the blades in higher winds with a gearbox increases the complexity, but would be feasible due to the increase in yield. Use Linear actuators to slide covers over the intake to reduce the wind during high loads.

The exit port contains the Honeywell wind turbine. https://www.youtube.com/watch?v=f1rtKh_CW44

1KW VAWT Powertree (Grid, Island, Hybrid)

The 1000w wind generator comprises a multiple bladed rotor with a vertical axle, and is designed as a so called upwind rotor. The nacelle is bolted to the airfoil mast, and houses the rotor, bearings and generator. The gearless synchronous generator produces three-phase alternating current. A wind vane is not required as the yaw drive functions automatically. . The yaw bearing with the slip ring joints is fitted below the airfoil mast. The bottom face of the yaw bearing forms a flange which can be used to connect a tubular mast.

https://www.youtube.com/watch?v=_z4K7w3tM3E Turbine build tutorial: http://solarflower.org/tutorial.php?lang=en&tut=vawt The generator is rated at 1.5HP / ~1kW which the turbine should be doing in about a 60 km/h wind, at about 90 volts. This video is just an incidental update, mostly on the new chain drive prototype and pole mount configuration, I'll be doing a full documented update at some point soon. The cost breakdown is about $25 for the turbine itself, $45 for the treadmill motor as generator, and $95 for the pole, steel rope and fixings etc. Known Issues With The Video: ~ Yes the steel ropes start out mounted below the turbine then jump to above it, turns out they work a lot better up there. ~ Yes the pole wobbles a bit, in future I'll have probably just some polyprop rope to the pole mid point to lock that off and stabilize the whole thing. ~ Yes the chain is off when the turbine is up and spinning, I didn't have it tensioned well and it dropped but then also didn't have the time or assistance to take the pole down and re-establish it before I had to leave. It does work fairly well tho. ~ Yes for now you're going to have to take my word for that. ~ The video is largely out of focus but my phone camera either auto focuses constantly or not at all and the latter is slightly less annoying. ~ The turbine does pop a bit when it spins, but it's not loud and I'll try to resolve that. ~ Yes the back two ropes are crossed at the top, that's for reasons. https://www.youtube.com/watch?v=t9TrUPoevXI https://www.youtube.com/watch?v=_z4K7w3tM3E

this is a scam, evaluate the other vertical designs rather. http://icewind.is/en/ The IceWind CW turbine is the first product designed by IceWind and has been in trials now for 7 years. The CW was originally made for non-geothermal areas in the harsh Icelandic weather conditions but suits well for all residential applications. https://vimeo.com/175852127, https://www.youtube.com/watch?v=Wlxz-KzebbQ

https://youtu.be/mDBNFY2BXKU The O-Wind Turbine was invented by two students from Lancaster University in the UK, who won the James Dyson Award in 2022 for their innovative design. The device consists of a spherical structure with vents that allow the wind to flow through it from any direction. The wind causes the sphere to spin around a fixed axis, which is connected to a generator that produces electricity. The device is small, lightweight, and easy to install, making it ideal for urban and residential areas where space is limited and wind conditions are unpredictable. Unlike conventional wind turbines, the O-Wind Turbine does not require a minimum wind speed, direction, or height to operate, and it does not produce any noise or visual pollution.

Anyway, testing with even a not so perfect prototype (but it is always the way first prototypes are, aren't they 😋) is always a good idea, as it gives leads to what could be improved ans new ideas - keep on the good job ! 😃 https://www.youtube.com/watch?v=XPZei_UONX0 Aeromind https://www.youtube.com/watch?v=JJDyIOtr5yA zephyr no noise http://www.windenergy.com/ and http://peswiki.com/index.php/Directory:Enviro_Energies Mag-Wind For power conversion to electrical, use the dynometer idea from solar links on making a home-made DIY dino 1kwH. http://www.lowtechmagazine.com/2009/04/small-windmills-test-results.html lots of links ready to reverse engineer with HackPatents and sell in South Africa via fronting companies. http://www.turby.nl/ http://www.airdolphin.co.uk/ http://www.skystreamenergy.com/ http://www.crestaustralia.com.au/products/brochures/WRE.030.pdf http://www.fortiswindenergy.com/products/wind-turbines/passaat http://www.boost-energy.com/ampair/products_product1.asp
