Greetings. Thanks for stopping by and watching, and for the comments. Cheers.

Also a good demonstration that it works in reverse. Water in at the top causes the screw to rotate (as used in some hydroelectric generators).

Hats off to whoever made those screws. So smooth.

Here, what is remarkable here is that the wall of the Archimedes screw rotates with the screw. Separating the two is therefore useless. If we look at many Archimedes screws in operation the outer wall is fixed and the outer is mobile and subject to leakage,friction and fragility.

Kinda satisfying sounds. Brought to memory the Myst Island games.

Those disliking must be expecting a video where Archimedes is screwing a water pump

That's cool.. 2257 years ago, it was High tech ... Archimedes also invented the pulley, the wedge and other things.. I want the screw for my backyard fishpond..

pretty cool..and it was posted on my birthday.. so there is an extra cool point for that too.

I remember playing with one at a playground near my house. They still have it....

Nice piece of stainless steel work. Must have been expensive.

thanks for this delightful demonstration of the screw!

It's an interesting mixture. The fabrication of the screws themselves is immaculate, and the rest of the system is very crude.

Great demonstration of Archimedes screw (and hydrodynamic screw when he stops turning and it reverses its motion. Why doesn't someone make a hydrodynamic screw, and add a smaller diameter "water auger" on top so that the hydrodynamic screw powers the Archimedes screw above? That would be really cool to see! And maybe the people who made that lovely demo could do it and even get a grant to make it.

great video to show an example of the inclined plane for students, thanks for sharing.

i remember going mad on one of these when i was like 7 years old

JUst move down the road to Wales, it never stops raining = no need to raise water - lol

Archimede is know to have been the first man recorded to use it.. but the truth is thst most of the technology that he was using was learned from all around the place... and from thousand of year before him. that is the truth

There's a couple of these in Sydney, Darling Harbour.

Man I would be turning that pump.all day.. 😎

Very nice video !!

Kinda relaxing...

Yo le puse un molino de viento y un acaj de cambio y además que agrande la poza para no perder agua al subirla.

Interesting video 👍

magpies drinking out of a coke bottle know if the water level gets too low and they cant reach it they can drop pebbles into the bottle to raise the water level to where they can drink again this bird knows archimedes principle without high school teachings

now build one out of fiberglass water slide components .. have bottom end on floats.. as long as you only scoop up half the tube of water.. it won't pour back.. it will move water up much faster for irrigation..

Was looking for inspiration on an aesthetically pleasing skimmer for my pond.. So.. Time to break the tig welder out then..

Are these Archimedes Screws purely decorative, or do they serve some purpose?

A double Helix would be interesting

Cool..I saw this 1st time.👍

really cool, what s the minimum RPM to pump the water? and how is the Q?

Is this an educational installation at the park?

if you connected the turning side to a water wheel you could have a free energy water pump

Cool

I wish someone use this to make a water cooled PC.

Love it make it practical 💘😻💜💛💚

Архимедов винт,👍

Does flowing water at the bottom power it's rotation or do you need someone to turn the top of this device?

Wouah! Le même système que les jardins suspendus de Babylone!

good

This method use in south india 1000 years ago

Does electric water pump work on the same principle?

Wouldn't it be better with a handle?

Se tivesse uma roda de vento para acionar o parafuso funcionaria ?????

why not turn a tube in a rod instead

Fantastich.

Think that'll neat the schit outa ya if you tried to get a drink

nobody knows why, it just is

Can it be done vertically? (Not diagonally like pure perpendicular

Muy bueno

How to make this? Do you have a tutorial video of all this?

Pipe song

what was this?

can you make it vertical INSTEAD OF BEING INCLINED>>>AND STILL CAN RAISE THE WATER UP???? IE: TO PUT THIS SPIRAL DEVICE IN A BARREL OF WATER AND TO MOVE UT; as you doing; AND STILL CAN SUCK OR RAIS THE WATER UP TO THE TOP OF THE BARREL???? ID YES THEN PLEASE RESPOND TO BUILD ONE FOR ME : AT THE START FROM PLASTIC . THEN IF IT WORKS IT MAY BE MAKE FROM STELL OR ALLUMIJUM OR ANY OTHER MATERIAL>!! IF YOU CAN: THEN PLEASE RESPOND AND I WILL PAY YOU WHATEVER YOU ASK FOR!! CHEERS

very wet

So if I understand your hire a couple kids to stand there and turn it all day. Other then that it’s awesome.

I'm going to guess most people didn't search for this.

I can't understand that

what about using a pump

The only way this could be dumber if it were powered by an idling v8 engine.

і що це таке?

Что это было???

EZ

Блин как достали, при показе некого устройства держать камеру криво. выдавая что это типа попытка заинтересовать.

Looks like a pretty useless installation.

but why
