lol at everyone saying "get rid of those 90 degree bends and you'll get a better result!" when the whole point is having the wind collected up high to run the turbine on the ground.
In all my years of fabricating headers for my racing engines I have discovered that as long as the header tubes were the same size and all the bends were smooth on the outside radiuses, a bend had no real adverse effect on the air flow. As long as our headers were at approximatly 18 inches in length, they would scavange exhaust pulses very cleanly. Mainly because engine exhaust travels in brusts from the cylinder exhaust port due to firing etc.
I think that had he put a pointed cone inside the center of the fan to direct the air to the outside angled blades smoothly. rather than against the flat center plate, it would have been much more effectient. Plus had the venture been necked down at the fans input hole it would have inscreased the wind speed some as it was dispersed by the center cone. And elliminated the overblast against the side of the fan blade. Air does not like to make flat cornereed turns! But give it smooth outer walls to flow against and you will get much less turbulance.
But that's just my opinion.
Congrats on 10 years on RUclips mate
You could put a cone in the Center of the Impeller to help guide the Wind towards the Impeller blades. I guess smashing it on a flat disc is not ideal . Or you could try the Mini- Rose in combination with the Pipe, as it already has a cone in the Center. Or you could take it a step further and create an Impeller-Rose.
Exactly my thought too! :)
As soon as u saw that turbine I thought that we were getting another iteration of the rose. Can't wait to see it in service
Absolutely Exciting. Considering the problems of the world, you demonstrate that all is not lost.
Venturi makes air to speed up. In this system is better axial turbine. Put on that pipe some fan for WC venting. If you have radial turbine put air around the sides with some snail like housing. Air can get more speed before it hits that blades. Air can be directed with some little wings. Just like turbine in car.
Idea for a video for the naysayers; the long term generation of miniature power units.
You could politely remind people that even a small measure of power accumulates, and a small turbine like that could easily charge a phone while you are sleeping and otherwise not using it.
Perspective is key. Keep chugging through it mate!
i guess ppl dont believe in "overy unity transformations" so you have to market these things as "energy converters" cause thats all people understand, when they put fuel in their car.
robert, the 90* elbow slows movement of air. you should get an increase in air movement by eliminating one of the elbows.
Get rid of both elbows!
Robert……
you are a GENIUS…….
lol - wow - cheers mate - not so sure about that hutch - but thanks
@@ThinkingandTinkering The more i watch your videos….
The more you inspire…..
I have a young lad that we are building bicycle trailers. He builds and races off road race cars. He built trailer #1 almost three years ago. It holds a 400wh battery and 200w of solar. And i rode it across America , California to New York.
I get up to 80km a day propulsion from the sun carting over 150lbs of camping gear.
Paul lives dab smack in the center of San Francisco. I plan to be heading up there latter this month to continue working on Camper/Trailer #2. It has 1000w motors in each wheel made by Grin from Canada. We are designing it to explore The Baja outback . I even have a small fridge/freezer to go into it…….
I am SUPER honored you responded……………
Looks like a solution to what you described in video one.
A cone at roof line that has a tail to make it face the wind.
A 4-6 inch pipe down to ground to turn this design.
I recommend that the end be tapered down to increase the force of the to the turbine intake with a 1-4 mm stand off to suck in ambient air.
Then a capacitor After the generator to take load off the
turbine/generator.
Looks good for proof of concept. The bigger build will be great.
Thanks for the post.
Too many people don't understand the concept of proof-of-concept. They want a full solution right off the bat. It's most evident in the views of employers that want people to fix every problem that arises instantly with 100% efficiency and if you can't do it then you failed. It's a real problem.
Thank you. I think it is interesting. Because in Denmark we are not allowed to set windmill up in the garden. But with this setup you can hide it and only the cone is visible and flush with the wall👍
When you remake the turbine with tighter tolerances, see if you can extend the rotation shaft into the elbow and an adapter, with bering, inside the elbow so as to keep the rotation from tearing it off kilter.
This is great and the fact we can still wear t-shirt and jumper outside at this time of year is pretty nice too
lol - yes it is lol
I am wondering what the difference would be it you eliminated the friction losses by removing the 90 degree bends and either used a straight pipe from the collector into the turbine or if you used 45 degree or 22.5 degree bends.
Redirecting the wind certainly has a lot of merit and there are other ways that come to mind well worth considering
Roof ridges and corners of buildings for starters or the plant room itself being the air concentrator
Concentrating the air raising the temp would make heat pumps more efficient set after the turbine would help efficiency and could provide heated ventilation to boot and first stage to air compression for second stage compression for surplus electrical get all that heat baby
I really like this direction 😃
Great! 👏🎉
I have seen your funnel and tube were mounted vertically and mounted so that it could rotate so the wind goes in the funnel and is directed down but the funnel had a large fin on it so that it would always face the wind and then mount your favorite wind generator directly under the outlet thus a wind generator where the only thing actually moving in the wind is the funnel
Some people wouldn't get it no matter if you built a project capable of 50 kilowatts. LOL 😆 😆 😆
My first thoughts after watching your channel is how can I apply this to making my life better.
Love your work! Keep it up mate! 😉
Powering this puppy seems like a no brainier use for Solar energy. The panels could cover the entire length of the canals, providing power as well as shaded areas
Cool idea
With the fan horizontal and a contoured entry to the orifice to improve the venturi the inlet cone could easily be mounted on a vertical pipe and the cone allowed to self orient to the wind direction with the aid of a vane on the back which would also balance the cone weight.
fluid dynamics are awesome. :)
Happy newyear !
you too mate and all the best to you and yours
Like it! How about the small rose turbine in a funnel on the end?
Have you considered magnetic bearings as a 3rd element (friction) in the design?
Do I need to say it. Get the mini rose on there and give it a bash. Looking at other similar designs, they seem to use a turbine with a very shallow angle, similar to a turbofan turbine or steam turbine. I'd like to make one that the blade angle is adjustable to optimise the power extraction from the wind under different conditions.

What if the exit cone was 90 degrees turned that the prevailing wind blew across it? Would it create a Bernoulli effect actually pulling the air through as well as pushing in from the other cone?
Yeah that will create a Bernoulli effect and that geometry can be part of the optimization.
I wonder if a tesla turbine type fan would work on the end of your ducting, working in the opposite manner to the original
awesome robert!!!, now what about vortexing the input, would that not increase pressure
time to investigate those aspects of the Tesla fluid diode :)
Invention is a multi-iteration process :D
Try you impeller backwards. Multiple cones round the sides and air out of the center hole
i wonder if the air gap in from the cone tube. could be used to further pull more air along with it into your turbine ala the fancy ring arrangement that Dyson "bladeless" fans do.
nice! I was mulling that over too
A result is a result!
spot on mate
Brilliant, its like watching the Thinker at his real job.
Hi Rob, I would love to be able to tinker like you but have been laid up in bed for a month with extreme back pain so can’t do much but enjoy watching your progress. I have made a few comments re Venturi effect on previous episode’s. Would you get better results by placing the cone directly in front of the fan. Surely the pipe and bends adds drag, and does the air not loose momentum with a change in direction.
what you say is right mate but the premise here is to get the machinery on the ground where maintenance and installation cost is lower - that of course has a price in efficiency but, in my mind, it is really all about cost per watt generated at the end of the day
Hmmm..... Centrifugal impellers need air speed, not so much pressure. I presume without any plumbing it would spin faster? If you want it to be fed by pressure difference, feeding the impeller radially as if it was a Francis turbine, would be worth a try.
that is worth a try - cheers mate
What about a tesla turbine on the end? Either as the waste pipe being the inlet or have it going through the centre and out but not sure they work that way round?
I think it would work better if you changed the 90 degree bends with 45 degree bend. Just a thought.
Does the unbalanced spinning of the turbine make much of a difference for the output performance?
yeah it kills it mate
@@ThinkingandTinkering ok for a prototype however 😅
Gives me valuable insight for future reference though
Do you use ventilator in the white cône please?
I bet if you made one of these twice the diameter and a put it on top of an Aeromine you would get some serious shaft power from it.
Have you ever built a tesla turbine? It would be great to see your version. Ps how long did it take to wash the ink from your hands?😂👍
Why not connect the ventri direct to the fan, you will loose the resistance of the two 90deg bends
because you couldn't then sit the machinery on the ground and the cone in the air
Tighter tolerances and no wobble - should be good
This one is practically begging to be paired with the Darwin wind catcher.
Does the wind get lost in the impeller or is there a way to harness the wind again as it exits?
Would like to see the wind speed before and after the Venturi, does it actually focus the wind? Increase wind speed? I would assume so, but don't like to assume, I like to test and know.
Why do u need bends in the pipe when u can just stick the cone in front of the inlet? Every bend u put in results in energy loss.
how would you get it so that the machinery was on the ground and the cone up high? the is the point here
Be interesting how a tesla style turbine would work in your tube
Very interesting. I wonder what the effects would be if a cone was placed on the output end of the tube, that directed all the air right into the input of the turbine, or if this would make any difference?
How would that be done without interfering with the prevailing intake air?
@@fireballxl-5748 I was meaning that it would go on the output end of the tub, directing all the air into the turbine, instead of some of it going off to the side. At 1:59 the output is right against the turbine, but I assume there would still be a little air velocity lost as it hits the flat front of the turbine, and goes to the side. By the way I like your handle, I can remember watching that show when I was young. ;-)
@@howardg396 Yes and the other show was Thunderbirds are Go!
How to make water (instead of gas) run an engine?
yes
Please turn it out of wind Robert.
🙏👍🙏
I couldn't help but think what would happen if you used the turbine to power a flywheel, and then scavenged energy off the flywheel
Any energy you scavenge from the system will decrease total output. Energy comes from somewhere and it's limited.
Free energy if all gym bikes converted to produce electricity
it doesnt matter how much you demonstrate green energy it never catches on for some reason...
Seriously unbalanced
