Gravity Mill - any comments to this idea?

hi andi,

I know what you are trying to do, but this wont work. If you squeeze your water hose (or scaling down the exit) you give force to it which has to be overcome by the water pressure. This would balance out the heigher waterflow, so you have no results from it.

are you saying the water in your hose didn't go higher?  if you are not saying that, then the pipe reducer does this, thus higher water delivery.

Hi Stefan,
This is a first time post for me. Just to let you know, I am a polymer research chemist with over 20 years experience in the lab. I have been following this post for several days now and find it very interesting. I also follow the idea that keeping setups as simple as possible give the best chance at success.

Look at this sketch by Mr. Herring:

http://www.icestuff.com/energy/elsa/page_36_-_780.htm

Notice that it gives a solution to shuttle compression by pushing upward with the force of the gained energy (water). To me this looks like a very real and simple solution to shuttle compression. The only problem I see could be when the shuttle is ascending. Water flowing past and opening has an ability to create a vaccuum. This might pull the lever intended for compression inward. I don't know. This would block the shuttle's ascent. Maybe a spring could keep the lever in its little alcove until water compresses it from above. Just an idea.

I also don't know if we need to worry about the calculations so much at this point. Hypothetical and real values always vary and little glitches in the workings of an apparatus tend to pop up unexpectantly. Real lab work is the only way to test for these problems. If it works, it works. If not then why and how can it be made to work?

There does seem to be a good possiblility that Mr. Herring did have a working apparatus at some point in time, but where are the pictures? In fact, where is Mr. Herring. Is he still alive? If he has worked on this concept for decades then he must have some kind of working unit.

I would love to see a picture of a shuttle he built, or anything he put together for that matter. I don't believe every sketch is just hypothetical. He must have something that works and is in existance.

Just a few thoughts I am throwing out; and I want to thank you for all you efforts.

best regards, ResinRat2

tbird, surely the water will go higher when scaling down the pipe exit, but the shuttle needs to overcome this extra force... Nothing gained from it.

ResinRat2, I tried different ways to get in contact with Mr. Herring long time ago. I don't know if he gave up his project and what he is doing now. Perhaps he was not able to build his device - at least then he could tell us where the problem is.

hi ResinRat2,

it's nice to have a person onboard with such a background.  welcome!

Notice that it gives a solution to shuttle compression by pushing upward with the force of the gained energy (water). To me this looks like a very real and simple solution to shuttle compression. The only problem I see could be when the shuttle is ascending. Water flowing past and opening has an ability to create a vaccuum. This might pull the lever intended for compression inward. I don't know. This would block the shuttle's ascent. Maybe a spring could keep the lever in its little alcove until water compresses it from above. Just an idea.

of course the compression arm would be locked in place until it was needed.  if not, as soon as enough water was added to leveraged water container it would overcome the weight of the arm assy. on the shuttle side of the pivot and reguardless of the "vaccuum" or whatever, it would enter the pipe.  using this system, the arm should be ready to work well before the cycle is complete.

any thoughts on how to prove to these guys (doesn't look like my hose example worked) that if you reduce the diameter of the exit pipe at water level, it will be able to push the water higher?

thanks for being here.

andi,

tbird, surely the water will go higher when scaling down the pipe exit, but the shuttle needs to overcome this extra force... Nothing gained from it.

what extra force?  it didn't gain any weight because you moved it.  it can only create as much force as it weights.

have to do a little work ow.  be back in less than 2 hours.
