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,    https://www.google.com/?tbm=pts&gws_rd=ssl#q=yuji+ohya+kyushu+university&tbm=pts 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
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 2
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).

 * http://www.lynxwind.com/gull-wind-turbines.html VerticalWindHelical2.png 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.

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.

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.

In South Africa, copyright on hardware are meaningless as changing the design by 1mm invalidates the copyright. In contrast the UK has made copyright on physicals nearly akin to patents. South Africa's government has right discerned that patent protection only works one way: Down from rich white countries to the subjugation of black countries. Black majority countries can only export their minerals, not their manufactured goods.

DIY kits
Vertical turbines aren't as efficient as lift hawt turbines, but they don't generate the noise pollution of hawt. You have to be at least 300m away from a hawt in strong winds for sufficient noise attenuation. The vertical design isn't patented, allowing for large scale deployment. See Alternators for magnet and wiring construction. https://www.youtube.com/watch?v=0jLA2u_G4Dg. Modify the design by attaching a diy built planetary gearbox to the underside. The trick is to 10x the spinner cutting a magnetic field, allowing for much small alternator and reduced Neodium magnet usage. Cost effective magnets will obviate the need for a gearbox entirely.

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.
