AFKQuoteA tree grows slowly and is filled with fluids from the onset so does not require fluids to be lifted to the leaves as per Sophies rope and bucket analogyI just re-read this comment. Do you not see what rubbish it is? If a tree is 30m high, it GREW there. All materials needed to be lifted up there during the growing process. How long it took is irrelevant to the energy needed. How can you expect to be taken seriously when you misunderstand elementary things like that?If you accept that Energy is conserved in chemical and physical processes then you need to apply that principle in all of your ideas. You can't pick and choose what Science to use and what not to use. It's a consistent package - not mumbo jumbo, like your ideas.

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.gifA 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 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.
