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.
YES, I've seen it everywhere (seperation of outer wall and scew causing leakage). I don't understand why people don't just link them both like you said...
@@WiKiTWoNKa The first one was the really magical one for me. The FMV butterfly on the starting island blew me away back in the '90s lol. That said, I have RealyMyst on Steam which was nice to play through and switch back and forth between the old and refreshed graphics.
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..
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.
@@Blenderkim I thought having them both on the one shaft might be nice, (I made a video about it) but maybe having them on separate shafts is better or easier. Then it can be belt driven. (maybe with the belt gearbox from an old electric shop drill so that speeds can be varied). On a positive note, someone in a practical water power forum liked the idea and he said he would try to fabricate one. I think it would be a world's first if he does it!
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
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..
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
Maybe, but this one is very smooth and easy to turn. For an actual water screw for irrigation or an auger for moving grain upwards, a handle would speed things up no doubt.
@@Blenderkim how would I look this up I want to build a homestead on my property with as little electrical consumption as possible and I want to utilize as much of the land as possible if that makes sense so I have a natural spring halfway down my property and I want to build a dam and channel the water up the hill
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
no because what makes it work is that it always has somewhere to flow rather than straight down when its at an angle. if it was straight vertical it would flow down around the spiral, which it cant do here because it would have to flow upwards to go all the way down the spiral
@ aarti sharma : Don't think so. That would be like having a tube around a cylinder. If it was vertical gravity would just pull the water back down. You would need individual containers of water moving from bottom to top
I know. It is like water flowing uphill, almost. Only works if the contraption is at an angle, then as the spiral turns, the water slowly creeps upwards.

Presumably an educational toy/display at a park. Without at least a motor there's not going to be any meaningful work done and the water appears set to just spill out one end or the other.
