017 The Birth Of The Rose Wind Turbine - • Video
Turbulkent hydro - • Turbulent VORTEX Demon... - วิทยาศาสตร์และเทคโนโลยี
There was a Trolly in the town I grew up in 100 years ago that was powered by a micro-hydro generator. Water power built Britain and America.
That smile when the rose spun in the wind... Priceless LOL Great job Rob, thanks for sharing.
I love the fact that you appear to have so much fun doing these
"Roses R Red, Violets R blue", Sure like your ideas too!!! I look for the next 1s from you!!! I bet we each of us also do!
lol - cheers mate
Just saw this tech this morning on "Undecided". Very interesting concepts and micro experiments. Micro wind, micro water, power storage, solar, thermal storage, gravity storage, all may be key in meeting future energy demands.
I remember a guy who tried to claim your rose turbine as his own. He called it the liam F1 turbine😅
I think the turbulent turbines have a constrained exit for the water so that the vertical part containing the blades is actually full of water when running, it is this mass of spinning water that can transfer a large amount of energy as opposed to water running through the blades like a traditional turbine. This makes up for the lack of head / water pressure.
Usually the outer 1/3rd of blades is where all the power producing potential is. This goes for weapons like swords and sticks too.
Perhaps if you ducted the water to concentrate on that outer part of the blades it would use less water for the same output or make more power for the same volume.
Fish Hawk Lake here in Oregon USA has one of those big holes in it to drain overflow instead of it going over the dam, this would be GREAT to put in there.
Matching the vortex direction to your hemisphere would add some efficiency I think.
I agree! especially on larger models...
Your laughter is infectious! Cheers!
Micro-hydro is such a horribly underutilized power source.
When i buy myself some land, it MUST have a stream or river running through it so i can take advantage of that water, so i can live off the land more
Money down the drain
To bad I live in a desert
@Odysseus38 Same.
Yes. An ideal community project😊
what if a turbine was made following the principle of that coin funnel that people love ? Like one of those with a smaller funnel inside and they were spaced such that the water could run in between
A crazy idea Rob.
How would the O Wind do as a water turbine "blade"?
I'm currently in Brazil and from time to time we get the most incredible torrential downpours. It has struck me more than once that there is such a volume of water here that putting something like this in a roof gutter system could really charge up an electric shaver or two
Yes! ayant un moulin je suis intéressé par tout ce qui touche à l’hydroélectricité, et ce type de generation est très bon!
dans les prochaines vidéos aurons-nous la chance d'avoir une petite démonstration sur la bladeless miroslav? (ziroth en parle un peu) mais on ne sait toujours pas si c'est arnaque ou pas...
I thought that the increase in velocity at the center of the whirlpool was the advantage to this design. In the graphic you played at the beginning of this video the opening was something on the order of 1/5th of the size of the reservoir and in the center. Would you be able to achieve the same result with a smaller rose a smaller hole and more of a whirlpool in the center? I would try it myself, but I do not have the ability to do so.
Great stuff as usual. Two things sprung to mind for me. Suspending the generator above the exit hole, (obviously with the blades in the exit hole). And the second thought was, would this work with a mini version of the gerbil wheel generator rotated 90 degrees and blades added in the centre?
Great generators, always makes me think, a bit of a dangerous for small people and animals if left open .
Only the dumb ones are in danger. 😜
Is the better performance of the smaller opening a result of greater head pressure inherent in the funnel like design?
That's lovely for water fall charging battery with the help of solar power ..thanks
It struck me that the finished turbine is very much like a ships propeller. I wonder if a retired ships propellor would be too heavy to use in a similar set up.
Might try making a cone shape under the blades, attached or not. I see the blades turning from the gravity of water falling on it. Not really taking advantage of the vortex movement.
Electricity & water - always fun.
I wonder if you could harness the water coming into the down pipe from the roof gutter?
What about changing the position of the hole in relation to rose
you spin me right round baby right round like a turbine baby round round round.....i'll get my raincoat.
would be cool if they used these in the gutter systems of tall buildings so that there is like this zig-zag of turbines on the left and right corners of a wall's face, so that the same water is used to generate electricity multiple times on its way down. Buildings could be rigged with those step things also on the stairwells, and have some type of sandbattery that sucks up all that energy as heat for long term storage.
I think you missed a trick here. By using a set amount of water from a set height, you could easily compare how much of the potential energy each blade type has converted. I will never understand why the big original version doesn't have the generator and electric connections on top of a vertical shaft where it can be easily serviced.
Starting to resemble a hydroelectric Francis turbine...
I'm hoping to have another method for energy extraction from moderate to low flow rate water systems in a year or so.
Patents. What a bore. How about UBI and we just share all ideas?
With the generator under the impeller, wouldn’t the generator be flooded and fail?
So have worked out which fan works best inside your Darwin yet
You could have a large scoop to capture the waves
Looks great for grinding fish😂
The Vietnamese use such a device. Looks like an outboard motor with a long shaft that goes into that type of drain hole.
Would i be on the right path in thinking this vortex idea is trying take advantage of water cohesion as the water tail is kept central/conical and not broken into bubbles/foam therfore in effect creating a virtual higher head thus more power?🤔
yes
out of all the turbine concepts youve tested, which turbine is the most efficient for wind generation?
I believe that if you could just have a water wheel setup without the rose but instead have have the fan turned on its side and Apply curved blades set on a flat round plate base with a minimum of 8 curved blades affixed onto the flat round plate and using a funnel to concentrate the water flowing out of the bottom of the funnel to have a steady flow of water to then hit blades on a specific point of the curved blades will result in a higher turn rate of the blades and thusly a higher energy output of the blade generator...
It would cut down on the chaotic manner of the water hitting the rose blade setup facing the flow of water.
I think the chaotic manner in how the water hits the various rose blade arrangement does create some resistance that limits the spin rate.
I would attempt to make such a setup if I could access the materials but I'm disabled with a vehicle to locate the components needed to test my Suggestion.
that sounds very much like a cross flow Banki - Mitchel type to me mate
Tidal generation 🤔
Moderate flow, high torque
If you made the power nacelle look like the "Fenian Ram" submarine then it could be moored by the pointy ends with the turbines on each cone shaped end and a seafloor height adjustment underneath like scaffolding with a gravity base for added security.
When servicing is required, surface the nacelle and complete maintenance ashore.
Might be a reach but not impossible 😉
like it mate thanks for sharing
I would think that you are comparing apples and oranges here. Wind can be compared to speed, "Meters/Second" and longer blades can provide more power for torque. But water should be compared with torque and friction supplied by force. How much torque would your new underwater rose design be able to supply for spinning a loaded system. The weight of wind and water are very different when interacting with the systems. But very interesting. I just wish I didn't live in a desert. I would love to see the amount of load it can push under water.
Air pressure pushes a jetted stream of water which centrifugal force dissipates to rain generation machine
I love your videos, but I wish you would do a few that concentrate on producing a much larger voltage/amperage that could be used to do real life work, example 2-10kw at 120 or 220 vac or 1-2kw at any d.c. voltage. These small scale experiments are great, but the world needs big ideas that make big power, I realize this costs more, but I believe there are options that could make large amounts of power at relatively low costs utilizing recycled materials. A generator that can't even make 12 volts at 5 amps is basically useless for anything but charging a phone, but one that makes 10kw could actually power an average home, water heater, stove, refrigerator, charging an off grid battery bank etc. It seems to me that the same amount of work done to make a small generator could just as easily produce a large one, if the materials were cheap or free, for which I'd suggest automotive recycling places and industrial recycling services for free materials. Best of luck and thanks for all your hard work!
These would be great if they could be integrated into stormwater systems
this is very similar to a style of water generator I have seen used in videos I have seen from vietnam, the structures they use seem to be dotted around the countryside here and there, so they cant be particularly new.
they can typically only provide a few hundred watts look up pico propellor turbines
i will look iinto it mate - thanks for the pointer
Would more petals increase the speed of the turbine.
hmmm test archimed's propeller it can be better
Is this an ad? I've seen a lot of channels post about turbulent the past two days.
The fact is they are not that good and cost a lot. Better to go with traditional micro hydro.
Where are the whale tubercles?!
It will cost a lot in tap water… 🤣 (joking)
01:07 Does the missis know you nicked her pasta machine??
After about 5 years of dipping in and out of your channel I have yet to see anything that produces anything other than mediocre results that add up to nothing in reality, but as long as your sub count goes up I guess that makes it worth it.
Does the Coriolis effect come into play ? Is the turbine more efficient in clock wise or anti clock wise operation ? Just wondering.
