HV, it is the same as with levers or gears except we are dealing with cross sectional areas of pipes. If you had a lever with 10ins on one side and 1in on the other, then 1oz would lift 10oz. With water, if one pipe has an area 10 times that of another that it is attached to, there will be a 10 fold pressure differential. :8-):

So would a good example be< when you get in the bath, the water level rises due to the weight of the body displacing the water?
So a large diameter pipe containing water has a weight placed inside it thus pushing the water level up. The bigger the weight the higher the water rises?

Science for dummies this, sorry about that :puzz:

Has my lack of scientific intelligence killed the thread? :puzz:

Sorry, but i understand the concepts its just the scientific talk that goes over my head, i need to be told things in bathtubs and plug holes im afraid.

I hope it continues though, even if the jargon is hard to grasp.

We'll sit down together with a bathtub and plughole, HV, and I'll do my best to explain some of it to you. :grin:

LoL, thanks prajna, bathtubs & plugs it is.

So far i understand (i think) the vortex turbine and how that could be made, the problem im having now and always have is getting water to go uphill (the holy grail) without using any of the energy we have made with the turbine.

I think i get now how this may work with the weight in the pipe (well a little anyhow)
Thinking on it, the weight pushes the water up the pipe, say from a reserviour at the bottom to a reserviour at the top, but what would drive the weight to rise back up in order to plunge back down again?

Again, probably missing the point by miles :giggle:

Well that is the problem, HV. Gravity appears to only work in one direction, so if you need to send something in the opposite direction you have to do a little work. Sadly, nobody has found a method of circumventing this so far; probably because gravity is a 'law', i.e. it is the same everywhere, is not capricious or arbitrary and is unbreakable. Do you see there is a difference between that and the conventions commonly called 'law' in our society?

Moving water up hill in sufficient volume to be of use as an header supply is one holy grail

These bods seem to have achieved it in a fashion

two equal weights on either side of a pulley cord are not heavy at all. building a reservoir above your head is a much simpler way to harness nature and a good fire killer
