~THE WATER-CLOCK/WATER TOWER~ THE BEAUTY is that this is a LOW PRESSURE 25 to 45 psi system. No chance of backing any water back into the strata. The well is cased with a sealed-cap top end protruding a foot or so from the ground. Two one and one-quarter inch internal diameter threaded flanges are through the well-head-cap. One just allows the wind-compressor to pressure up the well while the other is a simple 1 inch internal diameter pvc 'straw' that goes into the water to about 5 ft. above bottom. And above the cap the pvc-'straw' goes where ever you want it to go. The higher the 'straw' extends up out of the well (sealed at the cap), the LOWER the psi atmospheric pressure and the EASIER it is for the 'straw' to send a healthy stream to where ever you want. This is the very same physics as allows any kid to drink a soda-pop up through a straw; aka 'not' rocket science.~:-) A tank about 10 ft.higher than your home-roof line allows ample home water pressure by the way and allows for SOLAR HEATED WATER AS WELL; which is very cool. THE ENERGY STORAGE is NOT within the well; it is the COLLECTED WATER-WEIGHT up in our WATER ELEVATOR TANK that allows the 'energy-storage' for winding our 'main-spring' POWER ON DEMAND SYSTEM. A smaller counter-balance tank can be filling AFTER the 'main water/gravity tank' reaches the BOTTOM of the WIND-UP cycle to act as the 'counter-weight' to bring the 'emptied' drop-tank back up into the top of the elevator 'silo.' THIS LOW-AIR-PRESSURE SYSTEM NOT THEORY: This is a tried and true 'well used' system; pardon the pun.~;-) Date: Wed, 2 Sep 2009 12:50:32 +0200 Subject: Re: [Vo]:Clockwork&RubeGoldberg From: [email protected] To: [email protected] Jak, underground compressed air is a good way to store energy I gather, it is seriously considered by utilities, but what worries me in the specific scheme you describe is that the compressed air will push the well's water back into the surrounding ground. Nick, I found the answer to your energy density question here: http://en.wikipedia.org/wiki/Energy_density Excerpts from their main table: Storage type MJ/kg MJ/L EEStor (claimed) 1.2 5.7 battery, Lithium ion 0.46-0.72 0.83-0.9 Flywheel 0.36-0.5 battery (NiMH), High Power 0.250 0.493 battery (NiCd)[5] 0.14 1.08 battery, Lead acid[5] 0.14 0.36 Spring 0.0003 0.0006 Springs therefore don't seem to be a practical energy storage solution (mass per stored kWh is about 1000 times more than that of other types) Michel 2009/9/2 Harbach Jak <[email protected]>: > Nick: The whole wind-driven 'water-clock' affair would merely be the > 'constantly performing' winding device for a battery/series(maybe five or > so) for the very design of 'mainspring' you propose.
