Who needs chem-trails anymore,
British to Test Geoengineering Scheme (http://www.technologyreview.com/energy/38564/?p1=A5)


In October, British researchers supported by the U.K. government will attempt to pump water a kilometer into the air using little more than a helium balloon and a rubber hose. The experiment, which will take place at a military airfield along England's east coast, is meant as a test of a proposed geoengineering technique for offsetting the warming effects of greenhouse gases. If the balloon and hose can handle the water's weight and pressure, similar pipes rising 20 kilometers could pump tons of reflective aerosols into the stratosphere. :eek:

That is insane. I hope the good British people see the lunacy of this stuff and rail against it. Does anyone else just get that whacked out feeling like, "are they serious?!" when they try stuff like this? I mean, do you really think the earth is that dependent on human intervention? It's sickening.

Not an easy trick- certainly not as easy as running a hose up to a baloon. A column of water even one kilometer high has an incredible amount of mass and could burst most pipes or hoses- that is why water for high-rise buildings brings their water up in steps- usually pumping it up to a pool on one floor where it is again pumped further up the building. Then as you go higher you lose pressure of the water at the top so the force for spraying gets decreased. A rubber hose- as reported in the piece- would not be able to handle the pressure. Then you have a problem with temperature and the water potentially freezing at one kilometer (or even 20) in the air because it tends to get colder the higher you go. http://www.allaboutskyscrapers.com/skyscraper_plumbing.htm

Plumbing engineers found out that as you lift water above a datum, you lose 1 pound per square inch for every 2.3 feet of elevation. This small but incremental loss makes achieving high water pressure at the top of a water column very difficult. Most water fixtures require at least 25 psi to operate or flush properly, so measures to insure consistent water pressure throughout the building must be implemented. As the building get taller, another problem arises as the water pressure at the bottom of a vertical pipe becomes too great for safe operation and building codes.

From the original article:

"How do you make a flexible pipe that can carry 6,000 bar of pressure that sways in the wind of the jet stream and guarantee that it will last?" asks Justin McClellan, an engineer with Aurora Flight Sciences, which builds advanced aerospace vehicles for scientific and military applications. "A typical oil and gas rig might see 2,000 bar of pressure, and that is with a roughly quarter-inch-thick steel pipe. Solving the one-kilometer problem is probably not very hard, but when you add up all the requirements for a 20-kilometer pipe, this starts to look pretty unrealistic."

Hunt acknowledges that multiple challenges put the project "on the edge of what is possible," but he says that all engineering issues can be overcome within five years. Full-scale deployment could be achieved for approximately 5 billion pounds per year, he maintains.

(Five billion pounds a year would be about eight billion US dollars).

Best comment in the comments section:
I see stupid people,, and they don't know they are stupid. Unfortunately, they are in charge of much of our future.

The theoretically possible and the realistic in this case seem to be far apart.

OK. I go ahead and ask the stupid questions....I've got nothing to lose.


Here goes:


similar pipes rising 20 kilometers could pump tons of reflective aerosols into the stratosphere.

Didn't we just go through a "no aerosol" campaign twenty or so years ago? Has our atmosphere changed since then? :eek:



Other methods of geoengineering have also been tested, including fertilizing oceans to encourage algae blooms and pulling carbon dioxide out of the air.

We live in the Chesapeake Bay watershed (Pennsylvania).
Why are farmers fined around here for letting fertilizers get into the rivers which then dump into the ocean?

The British are coming!!!!!!! Been trying to tell you people! **** wheres Paul Revere when you need him.
