Hi Gabriel. I know what you mean you are right at some point. In reality the screw rotates faster. However a lot of research went into this subject that proofs no damage on the fish whatsoever. During these tests the fish were netted out after each passage and assessed for damage, including pinch marks, scuffing to the skin, haematoma and strike marks from the leading edge. Each fish passed through several times, with a rest period of 2-3 hours between passages. Tests by Fishtek Consulting.
Make one that kills the fish and sends them to a freezer which in turn is powered partly by the turbine itself maybe? Include a sensor that tells the cellphone when the freezer is full of fish :)
Thanks Wesley! Jij had hem nog niet gezien natuurlijk. Ja vorig jaar is er nog een aanpassing gekomen en we zijn er zelf ook wel heel content mee.... Thanks for watching!
maybe it's just where your from dog, here in uthranasia, we have yellow-jacket trout. they go around in a mollusk like shell that looks like a traffic vest. Here in uthranasia we also have the same accent as middle aged pizza owners on Long Island.
I like this concept. Who ever designed it could probably try building a small model with 45 degrees (like in ballistics) and more spacing between the blades (the more space the more mass of water on each segment and less mass of the mechanism). Only building the models we can know if the increased velocity helps to increase the total output of energy.
excellent work, loved it. I am an electrical engineer, currently working on my undergraduate thesis. Can you plz tell me which software u used for simulation?
great idea! I have another one for rivers that doesn't impede waterflow....................i'll share after May 7th when the good people of the world can profit from it.
I have never heard of it, which doesn't mean it is impossible. It's more depending on the flow of the water (how much and how fast - or slow) Anyway: beter to contact the experts mentioned in the presentation -> Landustrie dot nl
If you encased the screw and completely filled the enclosure with water you'd essentially just end up with a pipe. Water would flow freely around the helix without exerting any appreciable torsional force on the screw's axle. The water needs to be divided up such that it cannot flow from one section of the screw to the next.
Matthew Bucknall no that's not true. it was just for the purpose of visibility of the animation. the weight of the water exerts force upon the uphill side of the blade making the axle turn even if the pipe is full.
Patrick Donohoe you would get less usable force if the screw was fully submerged. Water will for the most part just flow around the screw exerting very little force.
It works by the flow through the "cups" of the descending screw. It's the weight of the water that produces the power, so all that is required is that the screw begins at the high water level. Mind you, a ramp on the screw at the top will chop up fewer fish..
Just a question... when you say the generator turns the mechanical energy into electrical energy... isn't it kinetic energy, not mechanical? (Sorry if I'm completely wrong, I'm a bit nooby at all this)
You have a typo in the title. Should write Archimedean. What is the market status of these turbines? Or, put another way, what is the market adoption evolution of them: are they being used more often or is their market shrinking? I see this technology as being ecologically superior to other dam constructions. Visited a few dams and those surely won't allow fish and crustacean moving from A to B.
***** Thanks for pointing out that typo :-) The hydropower screws and dam constructions are to different solutions for 2 different situations. Screw turbines require slow streaming water and are a great solution for remote areas where a relative small investment can help in the power supply of remote villages.
I want to use an archimedes screw turbine on my property, with 20 liters water per second and a "head" of 2.5 to 3 meters. The turbine then can always run (be operarional) and when the sun shines, pomps can pump water from a 8000 liter underground reservoir to a "water tower" 3 meter tall. Good idea?
This was a good animation, unfortunately I think rather more helpful than the soundtrack would be to have a narrative so that you could watch the animation rather than read and miss it
+Damien Smart Totally agree with you.... However this was the explicit briefing of the client. (A lot of times the sound of these presentations is OFF on trade fares - hence: you have to understand this without audio too)
Please I want to do a video about the use of solar energy in the operation of water pumps, such as that presented here. So I want .you help me to get the program that i can use in my work, where i don't have enough money to buy the program So please help me if you can
its not used because its super efficent, its used in areas with small drops of elevation (3-10 feet) and used in areas where fish might get into the turbines.
With such a volume of water for a second of time, my construction of a small hydroelectric power station will give one and a half thousand kilowatts. even more......
that screw spin because water descend downhill, the gravity pull water to descend downhill. to turn around the screw on the other way the water must ascend uphill, fighting gravity. what if the cloud gives rain on the valley, not on the hill.
If it works so well how come UN doesn't use the in 3rd world countries? Does it work with sea water if so island nation's What's the problem ? Cost or efficiency.😎🦊🎃
I thought only we Americans would be stupid enough to have horrible music instead of a narration regarding something like this. Horrible! Terrible! However, thanks for the effort and best of luck.
you guys got it all wrong... archimedes designed this to bring water from a low level to a higher level, not to be used as a generator. why do you think we use the pelton, francis, wells, and kaplan turbines? btw that idea is very old and instead of trying to make it work why don't you spend your efforts in making a new, better, design.
Keep thinking in the box man. You sound like your typical institutionalized and disgruntled engineer. I love it when people express their opinion as fact by just throwing out terms to degrade sound ideas. The pelton, francis, wells, and kaplan turbines are very efficient, but environmentally inferior when you compare it to the Archimedean screw. You are also wrong about the Archimedean screw being only used to bring water form a low level to a higher level. Although Archimedes primarily used it to operate in this manner, it was quickly discovered that they could harness a continual form of power to grind agriculturally-grown food and operate a crude bellow used in support of blacksmith (etc) operations. Why don't you spend your efforts doing more research before you make ambiguous accusations. Try supporting out of the box thinking, rather than waste your breath by repeating what you were only taught.
You appear to have at least some understanding of mechanics/engineering, so you surely should be able to understand that no one tool is perfect for every task. Simply put, these screws are used for applications where they are more efficient then turbines or other means of converting the water's energy into electro/mechanical energy or are used to convert the energy with substantially lower fish mortality.
so cool dude
Thank you. That is very kind of you Иван Иванов...!
Excellent detailed explanation of advantages & how the archimedean srew pump works.

thank u so much! it helped me on physics so much!!!
Excellent Technology!
A lot of good work went into both the product and the presentation. Good luck! if i'd need one, i'll know where to buy from now on :)
thanks! great product!
Make one that kills the fish and sends them to a freezer which in turn is powered partly by the turbine itself maybe? Include a sensor that tells the cellphone when the freezer is full of fish :)
Love the beats man.
Slick idea. You wouldn't have to disturb the stream very much and could get hydro power from small falls all over the place.
This technique was used in the Babylon Garden
Hey EnTWAdemalia thanks for you compliment! The track is "Moisture" from Cypher available at the Active Music Library at Allmusic.nl

why aren't we using these all over the UK?
La musique est vraiment idéale pour la relaxation
Any time.... :-)
Thanks Aasher...!
is this screw better than the old fashion wheels?
👏👏👏
How do the fish know what to do? Is there an instruction manual or even a replay of this video down there to help them out?
Hahaha... I hope so :-) I think they use traffic signs....
They have a cod just sitting around in a yellow suit directing fish traffic.
pounchoutz
You damned FOOL. They don't wear suits! They only recruit naturally yellow fish! In my state it is the yellow perch that does this job.
maybe it's just where your from dog, here in uthranasia, we have yellow-jacket trout. they go around in a mollusk like shell that looks like a traffic vest. Here in uthranasia we also have the same accent as middle aged pizza owners on Long Island.
It's all natural instinct
Thanks Wes...!!! We moeten nog steeds een keer naar Engeland voor de derde versie :-) maar je is leuk geworden hè?
★Awesome Report Thank-you!
Sweet!
Excellent technology to produce electricity when you have small
flows of water.

Alll 3D work was done in Cinema 4D, compositing in Adobe After Effects, editing in Final Cut Pro....
Love the video it really cUGHT MY EYE!
+Daniel Rankin THANKS!
Wow Nice!!!
great idea! I have another one for rivers that doesn't impede waterflow....................i'll share after May 7th when the good people of the world can profit from it.
how is it going mate
cool looks good but i have a question will this work with sewage water with need of treating the water first?
I have never heard of it, which doesn't mean it is impossible. It's more depending on the flow of the water (how much and how fast - or slow) Anyway: beter to contact the experts mentioned in the presentation -> Landustrie dot nl
@@STUDIOLEX ok thanks
I want one of these as a water feature...
Αρχιμήδης μεγάλος Επιστήμονας!!!!!!!Like!!!!!!!!!
I need this
Feels like entertainment for the fish
Why are the screws left open on the top ? Wouldn't it be more efficient if it was completely encased ?
If you encased the screw and completely filled the enclosure with water you'd essentially just end up with a pipe. Water would flow freely around the helix without exerting any appreciable torsional force on the screw's axle. The water needs to be divided up such that it cannot flow from one section of the screw to the next.
Matthew Bucknall no that's not true. it was just for the purpose of visibility of the animation. the weight of the water exerts force upon the uphill side of the blade making the axle turn even if the pipe is full.
It's both possible depending on various needs....
Patrick Donohoe you would get less usable force if the screw was fully submerged. Water will for the most part just flow around the screw exerting very little force.
It works by the flow through the "cups" of the descending screw. It's the weight of the water that produces the power, so all that is required is that the screw begins at the high water level. Mind you, a ramp on the screw at the top will chop up fewer fish..
I'm not sure... It's just a typical way to generate a rotating movement via a turbine into electricity. Hope that helps.
enviromental freindly!
Just a question... when you say the generator turns the mechanical energy into electrical energy... isn't it kinetic energy, not mechanical? (Sorry if I'm completely wrong, I'm a bit nooby at all this)
Thanks theLOLstick...!
need to know more
a question for the engineers around here.. would this screw type of generator work in a regular river flow, underwater, without any type of dam?
Probably can be incorporated in irrigation system to maximize water pressure and efficiency in construction in terms of budget
Brilliant
You have a typo in the title. Should write Archimedean.
What is the market status of these turbines? Or, put another way, what is the market adoption evolution of them: are they being used more often or is their market shrinking?

Lex de Prieëlle I understand.

Lex de Prieëlle Thanks, will do that!
formidable
We have 400 cubic water with 3 meter height. We want to generate electicity. How many energy could produced from it??
Please contact through e-mail at info@landustrie.nl
The river should be fast. The idea is not expensive, a small village is feasible.
Hi Lisa,
You can contact Landustrie Sneek BV for more information... Please visit their website and look for the contact part.
cheers, Lex de Prieëlle
How much flow we need lit/s
Please visit www.landustrie.nl/en/contact.html for more information....
Is this feasible? The dams generate more because the pressure which moves bigger shaft with same amount water this design moves.
Omer Yilmaz This is meant for slow streaming rivers.... Dams are a different kind ...

this cannot be the most efficient way to produce power power from moving water
..... beacuse....?
Because it is obvious that the Kaplan, Pelton and Francis turbine have already proven themselves to be efficient.
its not used because its super efficent, its used in areas with small drops of elevation (3-10 feet) and used in areas where fish might get into the turbines.
RPM??

With such a volume of water for a second of time, my construction of a small hydroelectric power station will give one and a half thousand kilowatts. even more......
it's not possible in real situations so use siphon so steady flow of water current become steady speed flow under constant atmospheric pressures
Please visit www.landustrie.nl/en/contact.html for more information....
Hahaha yeah that would be cool:-)
16 m/s ?? Then it would be a filet-fish dispencer!
Hey..... dat waren 2 replies voior de prijs van één :-)
Not feasible ull need a gear .and clean water cant be used even minor trashes mix in water.
if you use a fine net, you will have clean water
I don't believe a fish will make it through that meat grinder, it spins way faster than you portray in the video. You can make fish sausage though!

hi can I help me I have this small project in my college but I no screw turbine full information and measurements not available to me pls help me
यह एक काम्याब उप्करन है .
oh and buy the way this system is fish friendly
I'm too poor to buy the way.
when all water has come downstream, then the water must climb upstream
Ever heard of clouds?
or just spin the screw the other way around and the water climbs back up !
that screw spin because water descend downhill, the gravity pull water to descend downhill. to turn around the screw on the other way the water must ascend uphill, fighting gravity. what if the cloud gives rain on the valley, not on the hill.
i have seen youtube video shows archimedes screw being rotated by windmill receiving wind power. maybe that can push water uphill.
If it works so well how come UN doesn't use the in 3rd world countries? Does it work with sea water if so island nation's What's the problem ? Cost or efficiency.😎🦊🎃
If Landustrie gan help me with that? (does not have to be "free" 🤓)
