HChristian Screw

Like the Archemedian Screw, but better

This is a method for getting water out of the ground, but with no moving parts -- no axle. Instead this iron tube is a thin vertical screw at one end and a thick wide coil at the other, with a rifled inside chamber, but tapered into a vortex. Resonance with environmental vibrations will ensure that this Screw becomes a permanent fountain, pumping water out if the ground via resonance.

       I'm getting a bad vibe about the physics here.

       The vibration of the whole device brings the water once around the rifled thread inside the tube for each period, driving it up hill. The would eventually stop vibrating if it wasn't for the tapered nature of the spring which amplifies small resonances. Most of the small resonances would be related to the wind for the first few iterations, but once tuned, this device could be picking up periodic frequencies from the ground and from the electromagnetic field.   

       You could attach feathers to the side of the pipe and the vibration would allow them to give flapping support.

       Okay, I've been avoiding asking but what is it with you and feathers?

       I take tar and feathers and make a rapture out of it.   

       Feathers are like a 3 dimensional screw because of their s-shaped cross section and the spiral of the quill. No matter which way you wing them around, their push gets averaged out to be either against or with the screw and can be directed.

       S shaped cross section? Oh I have some searching to do

       kind of like a 3D S. Its funny, I cant find any good pictures online. But if you look at a feather its kind of down curved at the front edge and up curved at the back edge, so when your are scooping forward the feather catches as much air as possible and on the back stroke the back edge flips over and is a scoop in the other direction. It seems to me you could make giant s-shaped artificial feathers out of carbon fiber or another strong material.

       It's called a "catastrophe" curve; a cubic with three real roots, projected back along the z-axis to a straight line.   

       The two solutions for the points of inflexion represent the transition points between the outer surfaces of the manifold. The central region between the points is inaccessible. WKTE.

       I'm afraid I still don't understand how this thing is supposed to drive water uphill. Water is a pretty good damper of vibration. Vibration is a pretty lousy method of transport.

       Upsides: economical, elegant, environmentally friendly, energy efficient, easy to maintain.   

       Downsides: won't work.

       The really annoying bit will be one of the JHC's ideas will be profitable...leaving us HB-ers living on 1 potato a day or something.

       Well... dang.
If a resonant chamber could be made to induce Chladni patterns on the surface of a small pool of water, could globules of water not be made to break way from the pattern to be split over and over against geometric shapes built into the sides into ever smaller droplets as they climb the walls of a frequency-increasing diameter-shrinking spiral tower?
  

       Made for a cool visual anyway. (+)   

       // I'm afraid I still don't understand how this thing is supposed to drive water uphill.//   

       I don't claim the ability to decipher Our Lord and Savior's idea, but if you visualize a staircase with a slight lean back, then visualize the whole thing attached to a rotating cam water could be 'thrown' from each step onto the one above it in succession that would work.
