Respect pentru efortul depus,multa stima.
The original DWP350 Chris Olson design weighs very close to 300lbs, has a 4" diameter yaw shaft with bottom thrust bearing on the turntable, uses precision machined rotors accurate +/-0.04mm axial runout, the magnets are epoxied to the rotors as well as secured with stainless machine screws, about 3x times more tail area and has a 3.5 meter (11.5 foot) diameter rotor.
The Genesis is not the same machine as the DWP350 made by Chris Olson, Chris recommends a Rohn SSV tower for the DWP350 because 2" Schedule 80 pipe won't hold it at 90 feet.
In order for a wind turbine to generate power it has to slow the wind going thru the rotor's swept area, and that means thrust. A DWP350 produces about 860 lbs of lateral thrust @ 3.0 kW and even a 10 foot section of unguyed 3" Schedule 80 won't hold that without bending. That's why it requires a 4" shaft and mast.
Orlando cheapened up the original design, put it on a 20 foot tower where he gets his Santa Anna Winds at 40mph, makes a lot of these videos and thinks anybody else can do the same thing. They can't, and that's not how it works.
The bottom line with axial machines is that they only serve a niche market. For most people all they need for off-grid power for wind is one or two of the micro-turbines . All it needs to do is trickle charge the battery bank on those days when the solar panels don't work well. And those micro-turbines are perfect for that. They don't require an expensive tower, you can put up three or four of 'em cheaper than a big axial, and their purpose is not to fully charge a big battery bank like a big axial can do. They provide supplemental power to prevent your battery from sagging on days when the solar doesn't work so you don't have to run your generator.
So there is not a viable market for the big axials because they are too expensive. Few can afford the $5,000 to $14,000 it costs to put one up on a proper tower so they work. That is only viable if you live up north where the sun doesn't shine in the winter and you'd be running your generator 8 hours a day without it. There you can pay for a turbine that costs $14 Grand to put up in fuel savings over about 10 years. Otherwise, for hobbyists and people that need off-grid power in the more southern latitudes where the sun still shines in the winter, the smaller micro-turbines are the way to go because they're affordable and do the job for which they are intended.
# 1 , there is no viable market for axials. They make poor use of magnetic material compared to radial iron core like our micro-turbines use. So they are excessively expensive, there has never been a viable commercial design based on the axial principle, and they are only suitable for HOMEBREW enthusiasts who need one for off-grid power in the north.
#2 The Genesis axial flux wind turbine is not designed correctly. Everything on the Chris Olson DWP350 from the yaw shaft stub, which is 3" Schedule 40, .216" wall, and the yaw on the turbine head frame is 4" ID with a machined thrust flange on the bottom. The stator support is made of 3/16" waterjet cut steel, and not the light-duty little standoff's that Orlan hason the Genesis. Precisely 6 degrees of mainshaft tilt - same dimension used by the Bergey Excel - for blade tip clearance on lattice towers. The tail hinge angles none of which is correct on Orlan's turbine. As you progress thru the pages of Chris Olson's build, you'll see the stacking on the coil windings is perfect to keep THD
The Air Boss seems to be a solid American made machine there. That's what people need. Go Missouri Wind!!
Yes, it's 100 percent made in America, all done here in Missouri
The evolution of the wind system. That folding tail is quite the innovation. Very smart looking piece of equipment. I like the bold, ultimate and "matter of fact" name too. Liked & shared on G +
NICE!
Thanks Dan. It is well built for sure.I'll be doing a talk video with Gary the builder and designer of the Air Boss. It will definetly be very informative.
Super! excellent video there Jeff, and compliments to Gary for excellent work.

Awesome setup! Using a gin pole, guy wires and an anemometer. Very professional setup! -Shane Rehman, Ecotech Institute, Wind Energy Technology, Aurora, Co
Shane Rehman Thanks Shane
That was so cool. Doesn't look like I will be able to install one myself...wow, if you asked me which one of all the wind turbines you have demonstrated for us I liked the most, I wouldn't be able to decide. But I really like the wood blades. I love the low wind requirement. Thanks Jeff.
Yeah the wood blades look pretty cool. It weighs about 100 pounds.
Sweet thanks for sharing! That is a nice looking turbine!
Looking Good there Jeff!! Save one for me!! It would be perfectly suited for my area!
Very nice looking unit, can't wait to see it perform.
Should be this week or next weeks video.
good job Jeff in Africa we need this
damn it jeff!! every time i'm happy with my system you show me something new that makes me spend more money!!!! i'll have to have one of these as well now!!!
Yeah, that's the idea Derek.
well like you told me before, things just keep getting better. I have looked at the kits for making these before. is this one a dual model or a single model? the dual models are pretty nice. the blades are the difference between the kits I have seen before. the rest is the same setup.
Jeff, those stainless steel bolts are going to be a problem in a coastal area application. In the absence of oxygen and presence of chlorine stainless steel will rapidly corrode. The way they are installed the shafts will be oxygen deprived and eventually a small amount of salt water from sea water micro drops in the atmosphere will penetrate the surround of the bolt shaft. When that happens the bolts will rapidly corrode and snap under load.
+Ramsaran Bissessar Well i don't sell this wind turbine and i agree about the salt air doing damage.
Thanks Jeff
Nice simple unit but how well do you think the wooden blades will stand up in a hail storm with 30 mph winds? I'm thinking the leading edge would get dented or chipped creating and unbalanced blade set with future bearing damage.
I was going to order a Falcon Mach4-Freedom 2, Tomorrow, well that is on hold now. I can wait a week or two to see the output of this unit, then order.
My final evaluation of the Air Boss, to expensive to build commercially, to heavy , ice gets in the stator and rotor plates and freezes up, locks the Air Boss up, wooden blades cracked at the end of 6 months.The tower must be 3" pipe minimum.The output not worth the cost of adding a Midnite Classic charge controller = wind turbine and charge controller costs over $3000.00 for a 1400 watt wind turbine.Hugh Piggot promotes this old technology wind turbine because he makes money off the classes he gives on it.This is my experience with a professionally built axial flux wind turbine.

I'm totally confused; Missouri Wind (you?) put up this video and then says the Air Boss is too expensive, etc?
MissouriWindandSolar
...and this looks like a beautifully crafted machine. I'm 2/3 of the way through building a similar unit and it has been slow going so I can appreciate the artistry that went into your alternator and metal work.

Beautiful blades !!! :)
Yes they are!
Just use balance weights and it will automatically balance...there used on commercial vehicle tires. It could probably be used directly on a turbine.
If under those nuts on the front face of the wooden blades a triangular plate with the required holes is used to link all the blades together, it would add immense strength to the system which as it is relies on the rear plate alone. If the front plate is used the bending moment on the rear plate would be relieved a lot.
Apart from that , it is an excellent generator and blade design even though the blades are a compromise especially near the hub which ideally would have more twist bear the hub.
+Carmel Pule' Apologies as somehow my video failed before the film ended. That is a good design with that plate incorported.
Very nice addition to MW&S. I still want a tower like that. Need full schematics. Finding the pole from oil field pipe is becoming very hard.
Yeah it does make a nice tower. The new Air Boss axial flux wind turbine is a god unit.
Good job !!! :) 👍🏻👍🏻👍🏻
Thank you!
Jeff, you never talk about VerticalAxisWindTurbines. Why is that? Seems like a good design to me...
Thanks for all of your videos and what you do for our community.
Well, i never really seen one that worked. All the videos i see are just blades turning. They are expensive to build and can get complicated.
Mate top stuff :) the blades look great.
Gonna hook up the Classic to it today. Possibly get some outputs.
I need 1 ASAP!
Very Cool wind turbine. Do you have test kits to test for wind mill viability?
Well done jeff, big fan of the axial flux turbine design, hugh piggot nailed it all them years ago and never put it into production. The peoples turbine.Do I want to know the price. Hell yes????
I don't have a price yet. That's going to take a little while to get all the manufacturers lined up.
Now i need to go see your new video.
I think it will be 1 miiiiiillion dollars lol
Looking good.
This should last a long time.

Jeff, can you put together a start up list for actually starting a power system? The ideal thing would be one the the components could be used to grow the system as you can afford it. Batteries seem to be the major hurdle I see to starting up, I'm I wrong?
Your right, batteries are the biggest cost. I will do a compete setup video that you can grow over time.
MissouriWindand Solar Does your product can be used near sea shore with high winds up to 260 miles per hour from Bay of Bengal ocean on the eastern side of India -- recently we have these high velocity winds for the first time in the city of Visakhapatnam -- State of Andhra Pradesh -- India - almost half the city got vanished Thanks
Jeff, I have not seen you talking about the Axial Flux wind turbine. Do you still have them
The vertical ones that face up and have less tangling wires to worry about i always wanted to build because they don't spin in the direction of the wind they spin in a still position and power battery bank from wind coming dirty wind better only the blades are strange and many different patterns and patents.
A horizontal axis wind turbine (HAWT) rarely turns a full 360 degrees, twisting up the cable. We suggest making a loop at the top of the wind turbine cable to provide tension and keeping the cable from twisting.
You can add a slip ring if you want or simply check the wire when doing regular maintenance.
With a vertical axis wind turbine (VAWT), you typically need very large blades (8 foot+) to turn a generator that is going to produce much power. They also need to be very level to prevent wear on the bearings and keep the blades from stalling.
Thank you for watching!
That wind turbine is nice! Are you going to give one of these away for your next give-away drawing? ;-)
Let us know the cost when you determine it.
hey jeff it's 2020 how about a review of your experience with this unit?
Truly inspirational. How do you calculate tower load?
That's cool.
awsome. cant wait to see the price.
Under 2 thousand for the moment. I'll have a definite price soon.
what stops the wiring from twisting up inside the pole ?
Very nice!!~John
I like it. The quality is really something.Made in the USA right here in Missouri
To me, that makes it better!
Hi, this turbine is not a collector and coal! When the turbine is a vertical axis of the vertical axis, the wires are twisted! How do you solve this problem?!
We recommend a "wire tension system" where a loop is created with the SJOO cable. This provides enough resistance to keep the cable from twisting. Unless you experience very turbulent wind, the wind turbine should not continue to turn in the same direction and will usually turn back. A slip ring can be utilized but is often a point of failure.
I was hoping to see how much it can generate
Next video i will be doing output on it. We will have the Midnite Classic hooked up to it. No wind right now, suppose to get windy this week.
Muito bom. Só queria que tivesse pelo menos uma legenda em português... Parabéns!
big wind farm being built near here. 50 thousand pound nacelles 100 foot long blades bolted to a big nose cone hub. I wold love to install a wind turbine but the city government here can find fault in just about anything that you do. There is a phrase in planning and zoning about windmills. I would have to see what it says exactly
Yup, i hear that all the time.
Super !!! :)
I'm new to this, curious that if the exposed rotors and stator will be influenced by the rain. Can you tell me a bit? thanks!
Liu Bin No, the rain will cause no harm to the stator or make any difference in output.
Yes 👍☑️✔️😌🙌
Why wooden blades?
Betz limit has been smashed and debunked regards Graham Flowers
Nishtyak unit and blade itself liked more ...
جميله الله ينور عليكم ربنا يوفقكم ويوفقني معاكم
Anyone have a good blueprint for 'large' wooden blades? I used to have blueprints for ones made from 10 foot 2 by 8's but lost them. I have draw knives and am a skilled woodworker.
Jeffrey Johnson I don't know anyone that has those Jeffrey
cool
How much do they cost?
Price hasn't been set yet, should be in about a week or to.
Is it possible to get your email and to get in contact with your company? I have emailed the one in your website and there seemed to be no one answering it. Thanks.
Yes, email beth@mwands.com
She'll answer ya.
Well, while it looks good, I don't think that wooden blades will last "forever" as author claims. With all that ice and rain it will last no more than a year.
Do you use torque bolts? Those Chinese bolts are not fit for a coffin.
bohemoth1 We don't use Chinese bolts at all. These are all US made
+MissouriWindandSolar What about wooden blades cracked at the end of six months in USA what about using wooden blades in high temperature zones like in India ---
+joseph jeevanand kommuguri I would say the same thing is going to happen. Wood blades are old technology and no one uses them anymore for a good reason. You might get up to 5 years max out of wood blades or a lot less.
ooooooooo coold
You keep saying "axial flux" but never explain what that means. I have no clue. My next stop is google.
It's just the type of PMA it is. No iron in the stator core.
that going to be expensive to by can the be purchased on HP , [Hier Perches] ?
what stops the wiring from twisting up inside the pole ?
