Very Efficient Vertical Wind Turbine Once Thought Impossible to Build


fullerwindmill_t700As wind industry claimed that vertical turbines are ineffective, inventor Adam Fuller developed a project to prove this theory wrong.

He designed a windmill consisting of 8 turbines, each having 4 structural steel wind scoops. The vertical turbine has 32 scoops in total and the wind can blow from any direction making the blades spin. By now the prototype is working flawlessly and even the slightest breeze of wind can make its blades spin. The turbine has a 12 feet diameter and is 36 feet tall.

As nobody made a large scale vertical turbine before , Fuller thinks his will be the one: “I’ve been able to demonstrate that for every 10 feet of baffle, there’s a 300 percent increase of output with the rotor. So my thought is that a 40 foot baffle will increase output by 1200 percent. If the 40 foot baffle system is successful, that means that 1 turbine and baffle system (about $200,000), would have the same amount of power as 12 turbines without baffles (about $150,000 ), so there’s financial efficiency. That’s a big change” .

Fuller wants to build a 120 foot model of the vertical wind turbine which he estimates could produce 30,000 to 75,000 kWh each month, enough to power up with energy 30 to 70 homes.

His success in implementing a large scale vertical turbine will probably depend on government funding. But as his project seems to work perfectly he will probably not need to knock on many doors to fulfill his dream.

Hi, this is Adam Fuller (the inventor). I just stumbled across this and wanted to give an update. Picture of a MODEL of the latest design: http://www.journaltimes.com/news/local/86851b5c-878b-11e0-9252-001cc4c002e0.html My design creates a cylindrical vortex at the axis of the VAWT turbine. There are ZERO negative pressures therefore 2000% more power capability. Most VAWT’s are in the range of 3% efficient or less because of negative pressures. Also, wind passing on left, right and collapsing on leeward side of stationary baffle system help ‘pull’ wind through the baffles. This energy from wind outside the swept area helps increase efficiencies. Linked-in page: http://www.linkedin.com/in/majesticwi… Read more »

Congratulations Christi and Adam Fuller. Your has given us a great snapshot of people’s interest and understanding of this subject. Adam is probably onto something here. #29 Fancy, Adam’s turbine has a baffle (if its anything like mine this “cowl” has several segments. He is blocking the wind stream hitting the convex side of the blades (the return swing) thereby removing (or lessening) the negative side of the drag force balance equation: 0.5 *ρ A ( V-v)2 Cd) – (0.5 *ρ A ( V+v)2 Cd ) = Net force which solves to the velocity at the edge being 2/3rds of… Read more »

Multiplication of Vertical Wind Turbine Efficiency – The efficiency of vertical wind turbine can be multiplied considerably by making simple mechanical modification at the base of the turbine shaft. It functions on the basis of wind speed variation principles. An air pump type technique to be fabricaed at the base of the the turbine shaft. A shockabsorber to be fitted under the pivot of the shaft, which will help to creat up-down moment of the shaft operating the pump to creat air pressure and automatic releasing of air pressure giving force to the turbine shaft when the wind speed is… Read more »

Hello everyone! My instructor gave me 5 kVA Vertical Axis Wind Turbine as project study. He wants a design and he wants it “direct coupled”. Does anyone think it it’s possible? I think it will give variable output. Please help me…
Thanks!

Wind Generation
Guest

Wow, 75,000 Kwh a month. Now that’s impressive, especially for something built by just one person. I’ve never seen a wind generator with wind scoops before. I’ve only ever seen generators with blades. Now I’m interested to find out what the difference in efficiency is.

Hey, if anybody out there has any info on this please get back to me. The pma that i need to build is a 48v but i am not sure how to build it. I have built two single phase and one three phase and the three phase ran the smoothest but did’nt put out as much power and none of them put out what they were supose to. So i do not want anymore of those $47-$50 DIY e-books, just somebody that has a real good plan for low rpm and 48v. Thanks, Rob.

I would like to know how anybody saves anything on thier power bills by building a wind generator? The wind mill or vawt is cheep and easy to build but then comes the expensive stuff, the wire for the coils in the pma is over a $100, the fiber glass and resine… however thats spelled, is not cheep, the neo magnets are not cheep and there is the rectifier, volt meter,charge controler, inverter and the big one, the batteries. After buying the batteries you just lost any savings on your power bill, 6v batteries are $120-140 ea and used forklift… Read more »

I like all these ideas, they have potential. I though have a better one that makes all the above redundant. Stop using as much electricity, cut the population, ban the use of internal combustion engines and grow your own food.
Materials required: Nil
Road congestion: substantially reduced
Pointless journeys: substantially reduced
CO2 reduction: substantial
Sustainability: excellent

Hi Adam

Don’t let all the negative inputs get to you, product developent will always be full of negative opinions on all fronts.
I hope you manage to build your dream machine and show the value of the technology you have discovered….

Good Luck!

It has always amazed me how quickly the internet down-play zealots are ready to dismiss prior to having complete information. The turbine in the pic is only a portion of the invention. Critical parts make the turbine you see in the pic potentially as much as 1200% (yes 12 times) as powerful and DEMONSTRATED 600% more powerful. Due to the economy, a financial partner defaulted and I have not been able yet to build the very large machines (in the realm of 10,000 square feet of swept area). I have perfected however a smaller roof mounted version and have reduced… Read more »

Adam Fuller may be an inventor, but he invented nothing here. It’s just a variation of the Savonius Rotor that has been around since 1922. If he does something with that square cage around it, it would even be a bloody good looking variation. Nobody in “The Wind Industry” has said that these rotors are ineffective, because if they do what you want them to do, they inevitably ARE effective. For instance: no cooling truck has a HAWT on its roof, but they all have a VAWT, albeit a small one. They are however inefficient, especially when you want to… Read more »

My hat is off to all of you for trying to do your part to clean up the air. I am pondering building a wind generator, but my first project is going to be a very simple solar batch hot water heater placed in series from well to solar heated black tank under glass to interior Hot water Tank. Pondering this project, a thought came to mind. Why not use an old refrigerator box to mount the tank in? You would already have the insulated box, which would be fairly water resistant with the application of some silicone sealant. Anybody… Read more »

Vertical wind turbine to be looked at as simpler and no gear (at top) is required. I suggest combining wind and solar by making the blades metalic painted BLACK and tilted so to accept heat from sun, heated metalic blades will create flow of hot air that does wind action on airfoil, hence solar heat combined with wind rotate the vertical turbine. I think in middle east may be less wind speed but burning sun. In the night the reverse hapens, metalic blades cool faster than surrounding air that create another effect. Why not rain also does another action, please… Read more »

Hey All: There are a lot of interesting comments out there. I have built a magnetic train, a pnuematic robotic arm, and several other things just because I came up with an idea and was able to find the scraps around to try. If you do nothing, you will accomplish nothing. I live at the bottom of a hill at the end of a row of houses and it acts like a wind tunnel. I do not have a lot of room so my windmill will have to be vertical. Building the windmill will not be as much of a… Read more »

That is an interesting disign, very unique. I personally like to make my VAWT unique as well. My personal favorite is a three bladed savinous rotor, made out blue transparent arylic. Not as as large as your turbine though, only about 3 sq ft sweep area.
Two online sources I recommend to look at regarding building wind turbines, centurionenergy.net and otherpower.com

Yes, I agree. Until wind turbines of any orientation become as expensive per KWH as Nuclear or clean coal power plants to build we will not be seeing many commercial applications. When we figure out how to build one that we can be sold to the public over the next 40 years so corporate america can reap profit on it for decades, as well as charge you for the power it’s making, then we’ll see lots of them!

The problem with this story is that it makes no mention of the cost per kWh of the vertical turbine. I’ve talked to engineers about the physics of wind turbines before and the biggest problem is that there are few places in the US that has enough wind speed to generate cost effective electricity, especially if you’re talking about low altitude wind like this guy is proposing. The two biggest variables in energy potential of wind is: E = Surface area of wind being swept x wind velocity^3 x C The reason horizontal axis blades are used is because it… Read more »

Those who don’t know history are doomed to repeat it. Anybody with half a brain who does some research on this subject will find that there are many MANY studies that show vertical axis wind mills like the one this guy designed use more material and achieve less efficiency than a 2-3 blade horizontal axis propeller. if you want a really efficient vertical axis go look up “Darrieus wind turbine” Way more efficiency that what this pile of junk can do. And uses less material to build too. It’s reporting like this that dooms us to using oil and coal… Read more »

Will be interesting to see how the bigger model performs. I think it’s a bit optimistic to assume linear increase with size.. But hey, time will tell.

I’ve always thought vertical wind turbines would be worth looking into: they don’t need the directional adjustment and they are a lot more compact in some ways and you could have the “guts” of the generation mechanism nicely located at ground level too (advantages for servicing and safety of workers)
