Or simply dump the water so it spins counterclockwise. That's what is dictating the spin, not the Coriolis effect which only works across larger distances and is negligible here.
Absolutely love your videos sir thank you! Perhaps the added tube between the propeller and funnel allows the water energy to transition from rotational moment to a vertical one. What if there was a fan where the blades were in the form of a cylinder sticking out from the walls. As the water under centrifugal force from the vortex would interact better with that kind of blade. Again I love your energy! Keep up the discovery!
If you're going to centrifuge the water, would it not make more sense to use a centrifugal impeller, i.e., one whose blades have emphasis at the circumference...? You could maybe blend in a standard propeller profile below this to capture the remaining potential energy of the de-centrifuged water as it falls through....? Just a thought.
I feel like having channels in the vortex could in theory help direct the water flow much more efficiently, maybe even fins right at the bottom, just before it hits the blades. Bravo as always
When you flipped the propeller over, it looked like the blade angles do not reverse 180 degrees relative to the spinning vortex. The blades still split the water stream. Or did I miss something completely?
No you didn't miss anything just look at a boar with two or more engines on it and you may notice the propellers spin in different rotations. One propeller will spin clockwise and the other propeller will spin counterclockwise on a boat with two or more engines.
It's exactly the same if you flip it over. So that's a bit poorly explained. It's what is called a right hand propeller. Flipping it over doesn't change that. What is needed is a left hand propeller. But the point Robert is making is clear is is it not.
@@jclowe735 With 2 engines. That is correct and intended to eliminate what is called "propeller walk" or "wheel effect". The tendency for a boat to head a bit more to the left for a right hand propeller and a bit more to the right for a left hand propeller. Like the propeller has grip on the bottom like a wheel.
Slight issue when you turned the propeller over it made no difference to orientation of the blades was this a deliberate mistake? You need a prop with blades designed to run in opposite direction. Maybe an Australian one lol.
stepper motor? has got more than one coil, if you rectify each coil individually you can add them together in series for more voltage or parallel for more current, very versatile!
@@herenow2895 still forms a whirlpool. but its much more random which way it goes. once it starts its self perpetuating. source, had a friend in the navy for many years asked him.
The reason that boat propeller didn't work as well as the other is the blades was in the wrong direction for the water to catch it and spin it as if it was a hydro turbine propeller but if you got another boat propeller with the blades in the other direction it would be much more useful.
The boat propeller performs badly because it is the wrong orientation, it was trying to turn anticlockwise when the vortex was clockwise. So you can't just flip it over, you need to make or use a different (handed) propeller.
When we look up at a twister it appears to spin clockwise, north of the equator, but anticlockwise if we are looking down at it from above. This due to Coriolis effect and frame of reference. Cheers.
Great video, thank you. Do you think that using a smaller pipe or larger prop blade would increase output? Clearly the vortex is doing its job and throwing the water (and therefore the kinetic energy) to the outside of the pipe and its missing the blade?
My observation of the boat propeller was that as the water spiralled out of the opening it stuck to the walls and missed the blades altogether. Would it work better with either a bigger prop or a smaller opening then so that the water was guided onto the blades? Also if the blades where a very snug fit in the tube that would help too. I'm thinking thousands of an inch clearance.
hi robert i was hoping you could give me some idea on a project i am considering. i have a diesel hot air heater and the exhaust gets real bloody hot!!! i would like to harness this heat and maybe put to some sort of radiator system or storage heater type of thing. i did also think of having the exhaust going inside the hot air outlet to steal that wasted heat. but diesel fumes is a no no. what do you think?
i noticed that the water flowed between the blades also, maybe add a disk on the bottom of the impeller so the water flows outwards instead of between the blades
At 2:18 you flipped the propeller over. I guess I'm dense but I don't see that turning it over changes anything. The direction of the blade angle is the same both ways, isn't it? What am I missing?
I have a question we get power outs but on city water and still have running water. Is there a way to use that tap pressure ( garden hose) to generate electricity . If it has been done before is there a link , Thanks
With a high-pressure system, air gets forced outward and the Earth's eastward spin creates a clockwise flow. In the Southern Hemisphere, the opposite takes place: Wind around low-pressure systems circles clockwise while wind around high-pressure systems circles counterclockwise, coliorus effect. How would a Tesla turbine work in water?
Blades made like a savonius wind turbine should capture the full force of the vortex especially if they have a twist in them. This should turn a motor generator that has more torque with that volume of water quite easily.
if you broaden the blades so there is no visible gap when you look down more water would hit it. also extend the blades or make the orifice more narrow , it seemed there was water escaping at the edges !
Should you have the blades more perpendicular to the ground with that hyperparabolic funel? The hyperparabolic curves changes the momentum of that water from downward to sideways alot.
I live in a bedsit,shared bathrooms,so if theres a way to seperate "solids" ,away then water from them, and the washing machines ,this wee turbine could put a fair Dent in the generating for "Off Grid in City Bedsits"!! Im off to find the soldering iron,but 1st,paper and pen....
one of the advantages of this design is 'solids' pass through - no need to separate - so in a river the fish can go through without being hurt - it also means mud, stones and other 'debris' will also pass straight through
The boat propeller is reverse pitch compared to the other one. If you dump the water so that it spins counter clockwise instead of clockwise, the boat propeller will work better than it did.
does the length of the pipe negate the effect of the vortex in the water and thus diminish its effect on the blades? i.e. 0.5" pipe might gain the full blast of the vortex...?
Yet again fun experiments You might want to try again with a counter clockwise boat prop turning them over dosen't help much but you can get props desiged to run in either direction so your water would hit the flat of the blade alternatively force the water to spin the other way you might get a much better result 👍
@@davebutler3905 Hi dave, I don’t remember why I mention Coriolis, and I don’t see that RaperJason edited his message, but you seem to understand, that’s cool. 😀
The reason for the difference in the efficiency of the turbines is that your design is for low torque/high rpm which is the same as the fan motor, the propeller design is a high torque/low rpm design. If you used a high torque/low rpm motor for the generator you should find the propeller blade would be more efficient.
given the flow pattern, I would think a squirrel cage fan could be reverse engineered w/ an optimized blade assembly - something like a Savonius in style... edit, I see there is a Francis turbine already in use but that has a vertical shaft, i like the idea of bearings on the outside
I Just used Isopon car resin that I got from Halfords - it's a two part polyurethane resin mad for glass fibre - I think lots of resins would work mate
Hi there, just looking at your video again and thinking. The boat propeller has to cut through water, so perhaps thats why the water fell through and hardly turned it. At 3:58 theres 6 blades and no gaps from above. Also if you had a series of motors along a pipe, would the water from one above it feed the one below? - - - or would that lead to diminished returns. Anyway, interesting. Have a good day mate. Enjoy the daffodils, summers coming!. All the best, kieron
this is really meant for full flow and low head mate - in use the water wouldn't stop - it really did that because all I had was bucket so there was a distinct stop and start
@@ThinkingandTinkering When it is the only force, even the negligible force wins. If you dump that bucket from the other direction, it will spin the other way.

Yes it is true, for big air masses, but not when you pour a bucket of water, if you throw it one way or the other, the rotation direction will not change on a short distance.
If the water goes clockwise due to the rotation of the earth, then any thing that harvests that energy is slowing the rotation of the earth... The boys from Greenwich will be in touch
The orientation of the boat propeller blades is the same no matter which way up it is. You need one designed to propel in the opposite direction.
Or simply dump the water so it spins counterclockwise. That's what is dictating the spin, not the Coriolis effect which only works across larger distances and is negligible here.

worth a try
You need to put the turbine further up in the vortex, too much water is bypassing the blades
I think that is really to do with the stop start nature of the bucket of water I dumped in - this is really meant to operate 'full flow' so to speak
It looks like you might have the wrong angle on the boat propeller. The angle is not very clear from the top View.

When it is the only force, even the negligible force wins. If you dump that bucket from the other direction, it will spin the other way.
