I built a small strong vane powered alternator to replace the old generator on my 1941 J4 Cub. That was how they recharged the battery on the limited electrical system back then. I used a Delco alternator and adjusted the pitch so it didn't scare me from the high speed screaming. It came apart in flight one day causing fear and grief. I researched the alternator market for one with higher capacity thrust bearing and found a nippondenso. It worked great. For all you sharp shooters out there, no it wasn't stc FAA approved. I have had my life nearly ended several times by shoddy A&P mechanics. Being an ex Air Force mechanic, it's my life and I'll do the maintenance thank you.
So good to see people discussing and finding better ways to do same thing. Is there anyone who has professionally worked on small wind turbines projects ? I would like to discuss a couple of things and would appreciate any assistance.
The 90 degree cut at the blade base will like be the point of failure, better to just cut those two connecting points at 45 degrees and have the extra material for strength.
Thanks for the idea. I intend to build a slow speed fan in my workshop to circulate warm air from above the stove and across the roof, down to where I am. It has to be big, but slow moving, otherwise the wind-chill outweighs the heat gain (as I have found out with a desktop fan). At the moment it takes about 2-3 hours to warm it up by natural warm-air currents so hopefully this would speed that up.
@@devfern2270 I found out at more or less the same time about some very small fans only about 6" diameter. Spacing them one at each corner and each of them blowing horizontally towards the next one, creates a gentle draft and gave me the effect I wanted. They are often used by bootleg cannabis growers in confined spacers.

Interesting video. I heard also about so called "vertical turbines" - I am not sure if I wrote the name in English correctly. You could make a video showing how to construct such a turbine. Regarding to this video maybe I am wrong but I am a bit afraid if this construction resist in case of very strong wind (eg. screws, pcv, welds).
A variation on the Hub to make it stronger with a bit more bite in the overall pitch to allow efficient use to my most common wind preference is an easy carry forward. You have provided me with inspiration! Thanks.
As per my previous experiences u should add three more blades and also increase the length of blades for better results n more stable rotation even in slow wind speeds
A creative idea... you said Wearing eyeglasses when welding but it hasn't angle grinders power tool protection! It can cause damage if stones are exploded.

Cool solution. But the rear edge of the blades is allways 0° this is ideal. I guess it is worth to spend a little more time and fasten the whole blade with an angle. In this case you should put the edge with the different angele to the rear. I would expect that this would fit better to the different angle of attack along the different sections of the turbine. Do you have some experience what wind speeds can be hanled by such a construction?
I find that cutting the square notch at the end will eventually cause it to snap at that point (even with the steel), better to just a 45 degree angle there and have the extra material as reinforcement.
You've got a grinder and a welder and you still work on the floor? Build a workbench then build a vice. Nice little project though looking at the generator, I think you should upscale to something that will spin a car alternator.
This is a nice design. There's something I've never understood however. Why are wind turbine propeller blades so narrow? Wouldn't more energy be transferred to the blades if they were wider?
The supported edge should be the leading edge. Twist them. Also as noted in some of the other coments PVC might not be best choise as will become brittle or melt in the sun.
don't have your expensive wrist watch on when you do welding.....little bits of welding splatter are now stuck to the glass....and mabey a bit of dark broken glass could work as a welding shield so you don't need t o use that ......look close your eyes tack weld ...look close your eyes tack weld method
hey try conveyor motor on the turbine stator for your wind turbine instead and plug in wall (you get more out of it.)plus you get five billion views in five years. it has sixty magnets right conveyor is always one rotation per second on you put on dial. do it fast. then upgrade magnets for more amps and voltage. use power box extra one electric company one extra (IT WORKS YOU JUST HAVE TO REMEMBER TO GREASE IT.)
I have been building wind turbines for over 50 years. Using PVC can be really dangerous and Highwinds, just for your information. Not being negative, but you can build a much more robust airfoil using carbon fiber rod and dollar store foam board.
What do you mind with "1:3:20"? It's the measure for the top, the bottom and the large of the blade? Like 1 inch in the top of the blade, twenty inches to larger of it and 3 inches in the bottom of the blade?
Great insight into the build just subscribed and it’s a nice compact turbine I also have built a homemade 650 watts wind turbine, a treadmill motor turbine and a little but powerful ametek 30v turbine and built 2 diy solar panels, be careful in high winds one of my first turbines blew up 😕and now have only 2 wonderful turbines working daily 😊it’s very satisfying watching those things working, keep up the good work buddy 👍
Teach me too. If i want air to be pushed fwd & sucked from back like an exhaust fan. shud the blade curvature be different. Why do some house fans have 4 blades? Is it better for windmills with low wind speeds to have fewer blades?
Waouh is great. I like your videos . your are amazing. I'm a Cameroonian student and a fascinating to wind turbine. I want to learn to make it how can I do? Please can you help me!?

Yes, appalling "welding". Some modern metal GLUE would be stronger. Literally. The blades are a great idea (not new, but well demonstrated) as is the basic method of shaping and mounting, but the rest is an example of What Not To Do. For electrical generation, stay away from geared systems, unless you have a BIG propellor. Go for high speed blades (which these can be, with some finer shaping) and non-contact induction coils.

That will totally work. And adjustments could always be made to improve it, if needed. All by hand, great job and thank you.
This is a great great idea. Don't listen to the negative comments from people who criticize others, but do nothing themselves. Keep up the good work!
+Robert Baker, Thank you for your support.👍
the bike bearing and chains is a great idea as it takes away the strain on the motor's bearings.
So good to see people discussing and finding better ways to do same thing. Is there anyone who has professionally worked on small wind turbines projects ? I would like to discuss a couple of things and would appreciate any assistance.
Yes, this is great idea. I was think more the along the idea of soldered aluminum, but that might be bitting off more then I could chew.
Fantastic, Sir! Twisted, slim blades for a minimal cost! That's clever. I wish you god winds! Best regards, Andreas, Sweden
this guy has not got the faintest idea of real life in the physical world of engineering
I knew he is going to get a lot of pain for welding even before I read the comments. :-) Anyway, thanks for sharing. Good job!
+Vilo Conshmillo 😂😁thanks
Inplix has nice plans for that

Good job! Keep them coming. Thanks for posting this.
start small and work your way up to bigger and better things good job use what you can find

Instead of welding one can drill holes and use bolts to secure the pieces at 4:30...
Interesting stick welding, smart use of tube

As per my previous experiences u should add three more blades and also increase the length of blades for better results n more stable rotation even in slow wind speeds
If there r more blades wud it really be better in low wind. Plz help.
Gives me hope.. I can stick weld like that! :)
Very easy to make. You my friend, are a genius.
Great way to show a general concept.
Killer welding skills.....
A creative idea... you said Wearing eyeglasses when welding but it hasn't angle grinders power tool protection!
It can cause damage if stones are exploded.

Pls post a follow up as sool as you get some wind so we van see it do ots thing!👍
Keep the great job God bless you. While others talk you do your best.
good lines with an angle grinder. thumbs up
Super. Very helpful. Keep posting bro
I find that cutting the square notch at the end will eventually cause it to snap at that point (even with the steel), better to just a 45 degree angle there and have the extra material as reinforcement.
That's a good point.
I think, this is very great idea. but some times ago, I saw this method in RUclips. I want do it too :)
to keep the pitch constant the wdith of the blade is not linear but arctangent of the distance from the center .
You've got a grinder and a welder and you still work on the floor? Build a workbench then build a vice. Nice little project though looking at the generator, I think you should upscale to something that will spin a car alternator.
it was better if you could show us that it is working
Watch my most popular video. Thank you
There's another video where they have a shop fan in front of it and it spins. Yeap, success.
@@newphysicist tthank you
Welding level 1000, very smart little brown ! :D
This is a nice design. There's something I've never understood however. Why are wind turbine propeller blades so narrow? Wouldn't more energy be transferred to the blades if they were wider?
I think more heavier it gets if blades are big so diff to turn if low wind
Thanks for the tip! Realy appreciate it!
They'd work best if their 'pitch'-angle was reduced from the hub to the blade tips; like the huge commercial
commercial wind-turbines.
I really like your videos there is just something really good about them
Thank you so much.. I'm working on something more interesting. Keep in touch..👍👍
New Physicist I will, can’t wait to see it. Thanks
Nice welding, great video, Thanks.
My brother, I asked if it was made of aluminum with a thick thickness. But it looks like that can it be mounted on a zenithch750 stol plane?
A simple idea you can go to a local electronic repair shop and take a ceiling fan use the blades to make your own wind turbine
looked like a bird shat all over those welds
The supported edge should be the leading edge. Twist them.
Also as noted in some of the other coments PVC might not be best choise as will become brittle or melt in the sun.
Thats so helpfull bro, i gonna attampt to use it for low scale irrigation😊
good use of material for a rural setting......but don't breath the zinc fumes when welding!
Nicely done! Thanks for sharing.

0:34 "Safety First" but he has removed the grinder safety guard...... LOL
Johnny Jay Appleseed just crazy
And no gloves as he welds
i like it...
he didn't made this for run electric to entire vilagge...
just sharing his idea...
Verry nice work sir.......
Appreciable work.........
4:40 you should remove the zinc before you weld
A grinder and paint makes a welder what he ain't.

galvanized brackets makes for PP welding. should have grind the galv off first or brought non-galv. Good job though
