  • I have not read all the comments, however I MUST make this one=

    Denise is a VERY attractive lady. Sooooooooooooooooooo fine. Next time let her do the talking and show more of her. Mini-skirts work well......LOL

  • is there a way to make a generator for a pair of rollerblades

  • It would probably be easier to cut the pvc with a low set jig saw or circular saw. o.o

    As long as you can firmly support your stock.

  • umfang besser mit pi berechnen dauert nur sekunden

  • Thats rubbish! The wind is blowing hard, and its hardly moving!

  • Hi Denise hey Dan. Love watching you play while showing others how to make things while going green. It's great to see people with a sense of humor. Keep up the good work.

  • Is it just me or does this guy look like Messi?

  • @gummipo Lionel Messi? i will agree to that :-)

  • haha, you sound like me and MY wife. "this all sounds really compli----"

    "NAAAAH it'll be fine honey let ME worry about the complicated stuff"

    :)

  • seems like you could put a tac weld on the shaft of this onto a car alternator and then the wind turn the blades?then some way to keep the alternator in a stationary position while it turns the shaft.I like that you scraped the pvc in lieu of the clear blades as it looked a lot better,but would have been nice to see a part 4-7 maybe of adding someway to make this make power.btw watched all the video and liked every one

  • excellent work of cutting and good technique for cutting wood in circle

  • Dan and Denise, this is great...BUT, how do you then connect the turbine structure into a "generator' unit and will the central axis require a stabilizing accompanying attachments such as cables or framework?

    I am keeply interested in the generator attachment.

    Any plans or directions to a design plans or generator products?

    Please advise.

    thank you.

    Best wishes.

    lawrence

  • you also talk to much

  • I like the vert design HOWEVER (COMMA)...just as the wind pushes ONE side of the blades in one direction it would push the OTHER side blades in the opposite direction. Right? Therefore decreasing the actual effectiveness of the design?

  • I thought the rod got bigger when you used the green thing on it :b (Sorry for saying 'green thing' I dont really know what its called XD.

  • You gays gave me a great idea thank you grit videos keep it up

  • one thing's for sure tho... the acrylic blades sure look pretty compared to wood or pvc

  • addicted to circles.........need a better design dude...

  • addicted to circles.............

  • not sure about your turbine dan but denise is pretty hot so i'll keep watching ! :-)

  • Co za ględziarz !Kupa sprzętu mało talentu.

  • Co za ględziarz !

  • G'day Dan and Denise... Thanks for your great videos...When you cut the circle and get the slopping edge on the outside could this be minimised by turning the wood over half way through the cut.?....

  • You are a great comedy DIY team! I enjoy your interaction with each other, even if the end result doesn't always turn out as expected, but real DIY with honesty. I have watched several of your videos, and particularly enjoyed your discovery of the correct way to cut a glass bottle. Well done!

  • Greetings from Israel, Love your videos. What you do here is a sight for a sore eye. Good to see some people care about our home (planet) and our future.

    Eitan

  • @eshvartz THANK YOU FOR THE GREAT COMMENT:-)

  • it's amazingly boring!!!

  • how much wind velocity to make this vertical turbine turn like that?

  • lol design fail, I can create a turbine way more efficient and it also works horizontally.

  • could u replace the pvc by using bamboo? i know i could get some cheap bamboo of roughly the same dimensions as the pvc around here.

  • I really enjoy your video, I like how you always talk about security.

    I made this 'wood blower' . but the problem is... I never know how to fix it with bearings. I wanted to use lazy susan's which is pretty easy way, but lazy susans are very noisy. I live in montreal so I dont think the guy next door would love to hear that noise 24/7. So I thought about rollerblade bearings but I have no idea how to fix them. Any suggestion?:) Something that would last say a at least a years.

    Thanks ^^

  • @xeimarras dickhead, no one made you watch it.

  • Good job with excellent skill, dennise was so helpful!

  • A simpler method of dividing the circle at the start is to use exactly the technique he describes but to mark only 1 side of the circle not both. By drawing a line through the center of the circle you will automatically bisect the angle on the other side of centre since you are drawing a diameter. This cuts your measuring in half.

  • Denise is the best in the video, I want a date with her, she is beautiful, the video is interesting, but without Denise, I do not see it all.

  • I think you could make a sail based turbine in about a tenth of the time, which would give out more power, and cost less. Please do a video on sail based turbines!

  • I like your idea here, very earth friendly. I couldn't help my self but mentioning something. Now on something like this you don't need to be precise, but this is an equation to help figure out the total circumference of your circle. Take your Radius multiply it by 2 to get your diameter you said thirty inches and multiply it by pi or 3.14159 (there's about 100 digits past the point). D*pi=C for the more nerdy tech ppl like me r*2*pi=C.

  • This system is not very efficient. You will get a few watts only.

  • dennise u are so hot nice asssets u are a babe no sisrespect hollaaaa

  • Wow! Freehanding that 30 degree thing is damn scary. Do it with a jig saw or a hand saw.

    Chucking the rod in the drill and pulling it - that's clever.

  • Wow! Freehanding that 30 degree thing is damn scary. Do it with a jig saw or a hand saw.

  • I really enjoyed these videos.

  • Good tutorial, and nicely explained. Lady even prettier...Thanx

  • With such a beautiful helper must be hard to concentrate I would love to work with Denise too

  • haha.......you guy's are great together.

  • make it up as you go? What is green about this project?

  • You two have some great videos! Keep up the great work!

  • formula's

  • Hey thanks Dan. I have some ideas I been wanting to try and I can use some of your wood working techniques you used.

  • How much power could these wind turbines potentially generate?

  • Comment removed

  • Comment removed

  • a few of these next to the freeway should create some electricity all day and part of the night.

  • can you have denise wear a tank top in the next one? and PLEASE, don't talk so much!!

  • Shes got a sweet ass! What was the video about? Haha

  • she got sweet everything!!!

  • Great video, even though I am on disability I would love to work with you guys, where are you located?

  • Awesome, I Really Enjoyed This Video, We Are Building Our Dream Home In Lakehills , Tx, On 5 ac Right On Medina Lake And We Are Going Completely Off the Grid, I Already Have 7500 watts Of Solar Panels, And This Will Help To Supplement On Cloudy Conditions, I Greatly Appreciate Your Hard Work And Ingenuity , Keep Up The Good Work , We Will Keep You Posted On Our Project Thanks , Chuck And Mary

  • could you do a video of your property... please with cherries on top.

  • watch?v=nQyRAHc7uhw

    :-)

  • I enjoy the banter between you two. Fun.

  • Verticle turbines seem like a lot of work :'(

  • LOLOLOL she stares and smiles at the rod :O

    10:05 :P

    lol sorry i just can't help to laugh

  • You know another idea is Why doesn't some one actually use a Wind Turbine Roof Ventilator for power????? Hook up magnets and a stater plate. Or since most of them have a center rod ,hook the rod up to a pulley then a alternator. If some one knows why you can't do this I would really like to know the reason. The Wind Turbine Roof Ventilator are also called Whirlybirds in some country's.

  • did you use bearings on the axle at the center the pipe which should be a.5" to 2" in diameter metal well anchored into the earth. I know this was a demo but worth saying the Plexiglass blades were the better choice also looked fancier all in all a great job you did one of these day i am hoping you will decide to make a bedeni generator or demonstrate how to make a water purifier using the sun now this would be a great challenge keep up the great work

  • Ok now where does the POWER part come in I thought you were going to hookup a motor or something.. All you have here is yaed art.

  • @hitman40009 We will be doing a Dual Axial Flux generator soon, they are the best choice for wind and most projects. Time consuming to make but efficient in lower wind.

  • Dan,if you want some really accurate Blade Designs i can help in that department because i designTurbine Rotor Blades for Jet Engines and Steam Power Plants.I can design them for you with a easy to understand description for Blades that will give you great results free of charge,just drop me a line if you are ever interested. :-)

  • If you are making more of these or other circle type things, you should really make a small angle measure to just drop in the center and then all you have to do is mark outward.

  • Hello from Lower Saxony, Germany. Your Savonius rotor is a beautiful work. What interests me is, why did not the lid and the floor also made of solid material.? Due to the increasingly mass of the rotor runs at different wind speeds but after a lot better. I mean, the flywheel is like by the centrifugal force alone have the different wind speeds without major building modifications made.

    But otherwise a very good idea. Thanks for the nice videos.

    Anthony

  • Oh, no.. America.....

  • great work

  • cool, but looks like some details where ambiguous.. love the vid though, keep it up :-)

  • PVC is Very Bad for your health, When you cut, or burn it, the saw dust and crumbs should be put in the trash, ware a mask, & gloves..Don't breath the smoke, it will cause Cancer as well as the dust !..remove dust from you with care..KEEP kids away..no joke Poly Vinyl Chloride used for sprinklers, & plumbing, pools etc ! These are Great Videos ! Thank you !!

  • Thanks,

    You two are Angels,take care :)

    this is what earth needs :) people like you and projects like that :)

  • super

  • Hello from Oklahoma! I have been watching your videos. Now me and my son have some great projects planned for spring. Thanks

  • @myyllw71 :-) Thank you for watching.

    Dan

  • at .08 ... " you cut your work in half by a third " ??? and 10 divided by 3 is what ?? .

  • Did you mean using a compass? I would think it quicker. No measuring with a tape measure.

  • Awesome!!!

  • I got a lot of good ideas from these videos

    Also that with the circles was very good Thanks Cool Video

  • agreed. the whole point is to produce electricity. I got a lot of good ideas from these videos. But iI know from experience how difficult it is to build a generator from scratch. (just having rare earth magnets and wire). Maybe make a video that shows how to make a realistic, power producing generator, and then show practical uses for it.

  • I like the idea, but I would like to see it hooked to a generator producing electricity. I want to know what happens when you apply a load in a city setting.

  • Your wife is not hot. That's because your efficient VAWT is probably providing enough energy to power your indoor cooling needs. But seriously, he is hot and this a great vid. 5 stars.

  • Very nice, you could put the power companys out of biz! Go Green!

  • Few videos on youtube keep my attention the whole duration (especially a total of a half hour's worth). This video was outstanding. Watch out Bob Villa... there's a new guy in town that uses the same tools as I and doesn't spend a fortune! Thank you very much.

  • Thank you:-)

  • It looks like you guys are about to duke it out. Seriously your wife looks like she's going to beat your ass. Can you make another one of these and lip off to her just one too many times so we can see her beat the living shit out of you?

  • What in the world does that fast morse say at the end of the credits? Way too fast for me.

    Something like: BCUTA1WDC9 ?

    Cool video !

  • Comment removed

  • nice video!... gives me some good ideas...... and you're a lucky man!!

  • Awesome videos! But I have one question... how do you get electricity from this? I know how it's done in theory, but what is the practical hook-up, to a battery or to the powergrid. Any plans or anything for that info.

    Thanks =]

  • just set the blades 1/2 the distance by a 1/3 from each other for maximum effeciency. : )

  • I realy enjoy watching your videos.

    and i think you do a very good job on your videos.

    and i just wanted to thank you for makingf them

  • i wanna cut my work in half by a third.

  • Excelent

  • I'll keep enjoying the videos as long as Denise keeps appearing in them :)

  • pretty lady show lol

  • @Bertziethegreat

    YES! I AGREE!

  • getting any power out of it?  *laughter*

  • The blades are placed at the same angle left and right. How come it turns one way? Is it because of the advancing blades in front streamline it more (less "grip") than the retreating blades on the opposite side giving the blades going back more bite? If you look at just 2 opposite blades they would be in equilibrium wouldn't they?

  • A circles outer path can be considered Linear in direction so all the blades are the same direction. Vertical turbines catch the air flow because the aerodynamic profile is poor in one direction and enhanced in the other.

    The more extreme this difference is, the more efficient the turbine will perform based on blades only.

    There are different designs for speed and torque depending on the type of generator or workload required. Also based on wind history of your area.

  • yeap that woman is fine as wine, its good to see a white woman with some junk in the trunk that is not anorexic. Not to mention she is really good looking. I also like the striat forward approach to the vedio clips, thanks a bunch.

  • watching this video makes me want to go cut something.

  • Hey Dan & Denise, I am enjoying all your videos.. Very Good *****

  • great stuff but waaaay too much thinking for this type of contraption!

  • give me a break... pretty straight forward...

  • DAMN! Mr Rowhoust is a LUCKY MAN! YUM YUM!

  • lol the math is not that technical...

    360 degrees (A circle) divide by 16 (Number of Props) = 22.5 (degrees in between each line)

    Use a protractor and you are set... as long as you know were perfect center is.

  • Great video! Thanks for sharing!

  • Damn Planes? That was Probly me up there!

  • Comment removed

  • On cutting your blades, you might try cutting to length first. Then glue caps on both ends. Then cut in half. The caps thus make a mounting flange

    that you can simple screw to your plywood. that cuts out having to make all those mounting cuts at 30 degrees.

  • That's a good idea. You could then mount them with some sort of adjustable feature so you could fine tune the angle of all the blades to find the best efficiency.

  • I would like to see more of what it takes to get energy stored in a battery bank, or integrated with the grid.

  • how about continuing this prodgect with actual generators ect.ect.

  • I keep seeing these vertical axis windmill designs, but no oneswivels the blades so that they fold in when they go against the wind! You could use springs(or magnets) to make them pop back out.

  • They dont have to, with the angle of the blades, when the blade comes back around, it is set to have less resistance than the side that grabs. I know what you are saying, but a movable blade will increase the noise as it "whapps!" from catching wind.

  • one word.

    "perfecly"

  • dude to calculate the circumference just use C=Pi x Diameter

    C=3.1416 x D

    simple

  • Great chemistry as a team. You can make much better videos by: Get a third person to run the camera, get a better microphone, clean up the background (too much clutter, ruins the video framing), a little better zooming in and out to keep your faces always on the video. The presenters (people) are great, the video techniques need improvement. You already got the hard part, now get a good cameraman.

  • the last part was quite unclear ... !!

    how much HP can be generated by this design .. ??

  • Whats the ratio between blade area and horsepower/kw ?

  • SHE IS HOT! I want to do her!

  • NEVER use pvc for any part of a wind turbine. you can if you want to get some one killed!

  • why?! Please enlighten me.

  • no offense .. 11:15 .. nice ass !

  • She is beauty !!

    BTW... no berings ?? It does'nt realy seems pretty efficient at all :)

  • Méchant pétard la belle petite noir

  • Mean farter the nice/beautiful litte black?

    Je ne comprend pas. C'est qui le Mechant petard?

  • it's a big 5 star for nice girl

  • this is a great video, but you never show how to make the wind energy into usable energy.

    step by step instructions would be nice.

  • I was left with the same question? Ok.. Looks pretty.. how do I turn it into usable power. : (

  • use it to turn electric motor= generator

  • i know that but i've never done it before. i would like to see someone else do it and get some advice on where to get parts and stuff.

  • Didn't your 6th grade teacher teach you how to cut a circle in three?

    Can't wait for the electrics!

  • Damn planes. Lol, this is actually a cool idea and you could make it really nice looking with paint and such

  • very clever ideas, I am very interested in wind energy. Thanks very much....

  • it actually look pretty neat with the plexi glass

  • love your videos..got to scale it up!

  • No I actually like and encourage the idea of building one yourself. Anyone can contact me for instructions on how to build a wind turbine, it's actually very easy even for a beginner.

  • Where is the generator???

  • good video, lots of interesting information... and I have to say Denise is hot!!! :)

  • I'd like to add that you can use your ruler to pinpoint centers by measuring the midpoint of your initial "X", and repeating for each smaller increment. I think that would be faster than the plastic ruler. Anyway, LOVE your work, and thanks for what you do!

  • I was looking around and I came upon your post and I Love it! The only thing is, it's great for the fins, but what about the turbine itself? do you use a car alternator? Gears? How would you tie it into the grid? Battery? If you had solar, (or tried to make a cheap DIY solar) how would this fit, etc. I'm just soaking this all up. Lot of unknowns, but Great ideas!!! Also, how much power did you guys make?

  • expose pvc to UV? may be not the best idea.

    otherwise pretty need tutorial!

    seems never ending though... may be show a finished shot in the beginning.

  • ruin the threads with that pair of channel locks then they won't back off..

  • Nice video guys. Any idea about what the advantages/ disadvantages to more/less fins would be, thanks.

  • Very informative, but how do you mount it, this seams that everyone stops just short of this piont. Keep up the good work

  • i care about your project and the gurl too......

  • Ok so I missed the part about that black thing that appeared in the middle and seems to be the nexus of the whole thing.

    I did learn a bunch watching these - and I will do a few more times...you would be amazed what one can do with duct tape, bailing wire, old political signs and bicycle wheels ;)

  • God Bless, Keep up the good work!!!

  • Nice!

  • omg.... great commitment .. but make me sleep...

  • good job again...

  • This rotor is worse that savonius. Go to school and study windenrgy again!!!

  • i think u missed the point... they werent trying to compete with expencive designs.

  • its not super windy. .....(tornado passing by)

  • Why do you do the ruling on the edge. Couldn't you just take 0.5 between the crossings and than draw a line towards the from the center!?

    Thanks anyway from Germany!

  • Thank you for your contribution.

    Xavier

  • Wow, I'll try this. If you check my videos, I built a very large savonius vertical wind turbine, but the homeowners' association is making me take it down. But if I use a transparent material - they will never notice it :)

  • Another idea is to use those 2 or 3 liter soda bottles cut in half, cut out the shape of the bottles in the board, maybe even slotted. You can even line them all up the width of the board to multiply the effect. Fasten them in any way you can. Is many ways.

  • OK what I see goin on here at the end (I skipped the rest) is wind blowing her hair around, completely trashing the horrible microphone and yet the device designed to capture the wind is barely moving. I can't see that thing creating enough torque to be useful when connected to a generator.

    Moving on to the next design.

  • That's in low wind speed. When the concept of magnetic levitation is added it does even better. Thats where this design leaves traditional HAWT's behind.

  • dang... i just spent nearly an hour watching all these... and this thing sucks. not very efficient at all, and it doesnt produce electricity

  • hahahahahahaha

  • This doesnt seem to be a very efficient wind turbine. Woudnt the wind, on both sides of the turbine create a unwanted negative work on the system. Correct me if im wrong, and I most probably am lol. I do know thats why the angle on the blade is there, to reduce drag on one side while the other side has more drag but still... Very cool, very interesting project, just not the most effective turnbine imo.

  • there is always going to be an amount drag on the other side in less you build an enclosure for it and thats a hole other big debate on effectively channeling the air...

  • True. And come to think of it, even if the efficiency of this type of turbine is lower compared to other types, it still does effectively collect energy from all horizontal angles and thus can absorb more wind energy per square meter than other types of turbines.

  • i like the idea but i think with another material its better luck great projects dude!

  • I like your casual style, if anything it shows how simple these are to make. What do you use to transfer power to a generator?

  • Looking forward to building one of these with my boys. I'd be interested in seeing how the power is transferred. I'm gonna do more surfing, maybe you have a video on that topic
