Osmosis Capillary action and root pressure are accepted as the driving force for lifting water to the canopy of a giant Californian Redwood, towering a hundred metres and more? And these forces are producing flow rates up to and in excess of a 1000 litres a day in a single tree?Another theory is that the leaves, which are porous, can somehow suck water from the soil and evaporate it through the pores of the leaves? Ever tried sucking on a straw with a hole in it?Maybe there is another explanation:Herald Express, July 6, 1995, page 19. (local paper in Torbay, Devon)Eureka!Picture headers, text and pictures removed.Cliff experiment pulls plug on 300 year old law of physicshttp://www3.sympatico.ca/slavek.krepelka/exper/EUREKA.gif [Links inactive - To make links active and clickable, login or click here to register]A Revolutionary breakthrough claimed by a Paignton man is to be investigatedby top scientists.Ideas man Andrew K Fletcher claims he has disproved a fundamental law ofphysics dating back to the 17th century.And impressed by the historic experiment at Overgang cliff, Brixham, toraise water 78 feet without the support of any artificial aids,John Hunt, Senior forestry Officer for Devon and Somerset who witnessed theexperiment's success last Friday said: 'It was quite impressive.The rule that water will only rise 32 feet under atmospheric pressure whenin a column was effectively disproved."But Mr Hunt explained that he is a professional forester not a scientist anda report on the experiment would be sent to the Forestry commission 's AliceHolt Research Station,near Farnham in Surrey, for further investigation.Mr Fletcher's experiment involves a long water filled plastic tube, strungup the cliffside with both open ends placed in two filled demijohns.A small amount of a salt solution is added at the top of the tubebefore it is completely filled with water, this acts as a liquid pulley saysMr Fletcher, lifting water from one demijohn to the other, therebydisproving Torriceli's 17th century law.This explains how trees can raise water to their tops beyond the 32 feetlimit."said an ecstatic Mr Fletcher. He believes that the discovery also suggests amechanism by which all life on earth has evolved from the ground.The Experiment at Brixham Overgang Cliffs where water flowed vertical up a single 6 mm bore tubing using 10 mils of salt solution, demonstrating that a tiny amount of denser solution can lift effortlessly many thousands of times its own volume in water without any artificial aids, demonstrating clearly a non living physical cause of bulk flow in plants trees, animals and humans. The 10 metre limit for lifting water clearly needs some serious revision.

Osmosis is the reason that blisters form on fiberglass boat hulls. Osmosis is how waste products of metabolism enter and leave the blood stream. Osmosis determines how you, me and every living thing lives and dies. One would think that a civilization that spends billions of dollars every year on medical research would understand something as basic as osmosis. Wrong, wrong, wrong.Source: http://www.yarbroughlaw.com/Osmosis.htm [Links inactive - To make links active and clickable, login or click here to register] Or what about Root Pressure? Roots can squeeze water to the tops of trees? You what?. ROFLMAO. Sorry but every time I read about root pressure it makes me cringe.Or maybe capillary action? In other words, a tree is a giant sponge capable of blotting water from below ground level to heights in excess of a hundred metres at flow rates that can exceeding a thousand gallons of water a day in a single tree.Does the cohesion tension theory suck? How can leaves create suction when there are pores in them open to the air? Is it not like trying to suck water through a straw with holes in it? Andrew
Mathematical calculations designed to show it can't happen or can happen appears a little pointless when we can show it taking place experimentally and reliably so. Has anyone done the maths on the Atlantic conveyor system? If you feel this can contribute anything please feel free to share your results.
Thanks for your reply Andrew.I second Rosy's post.What I meant to convey when I asked what does the tree do when its photosynthates have sunk, was, what if this occurs long before Spring arrives? And is the concentration of salts normally found in water enough? Do you use the correct (natural) concentrations, as well as tube diameter, in your experiments?
To support your idea we need you to provide the maths which either shows that the conventional view is wrong or that your ideas about density are plausible.Without them you are hardly in the realms of science.
"Looking forward to your mathematical explanation as to how trees can evaporate 98% of all the water drawn through the roots at the leaf without affecting the density of the sap "That doesn't need a lot of maths.As long as the rate that the water is lost is that same as the rate at which it enters then the net concentrationin the sap remains constant and ther's no change in density.However as I (and others) have pointed out before, IF YOU WANT TO BE TAKEN SERIOUSLY YOU NEED TO PROVIDE THE MATHS.If your next post doesn't include that maths then we can all assume that you are trolling and ignore you.
But we know that cavitation takes place all of the time and that any break in the bead of the imagined cohesion tension generated by a flimsy leaf flapping around in the breeze would render the whole process redundant. Yet the tree appears to not be affected by the constant cavitations, which can be heard cracking with a standard stethoscope. But that’s accepted and to be expected in a belief -based system.
Gravity does not provide the energy?Gravity is the energy, gravity drives the sun, the weather and all of life on earth! Perpetually for now at least!Gravity can raise a mountain to impressive heights, cause tidal waves that demolish coastlines, cause volcanoes to erupt, yet cannot influence solutes inside a tree or indeed a human? Bullshit!
And all of you know what gravity is? Please let me know at your earliest convenience as this problem has eluded the greatest minds and to this day still does!
Hehe.Ok, now I'm laughing. We're in real making-stuff-up territory now.Sure the sun wouldn't be able to exist without gravity, because the matter wouldn't be concentrated in one place... but to say that gravity drives the sun is just ludicrous. What "drives" the sun (in the sense of providing the actual energy) is nuclear fusion. Nuclear fusion is not, repeat not, driven by gravity.
