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.
The scheme, called SPICE (stratospheric particle injection for climate engineering), is one of several proposed geoengineering methods under study. In this case, the idea is that particles injected into the stratosphere would reflect a small percentage of the sun's energy back into space, thereby cooling the planet. The concept seeks to mimic the cooling effect of volcanoes that inject sulfide particles into the stratosphere in large quantity. A 2009 study by the U.K. meteorological office estimated that 10 million metric tons of sulfide particles injected annually into the stratosphere would cool the planet by approximately 2 °C within a few years.
Other methods of geoengineering have also been tested, including fertilizing oceans to encourage algae blooms and pulling carbon dioxide out of the air. But a 2009 report by the U.K.'s Royal Society concluded that reflective aerosol injected into the stratosphere would be the least expensive and most effective way to rapidly cool the planet.
In addition to the pipe tethered to the balloon, airplanes and rockets could be used to deploy the particles. But Hugh Hunt, a senior lecturer in engineering at the University of Cambridge and a member of the SPICE project, says the balloon-and-pipe approach that his group is testing would be significantly less expensive. "Trying to use airplanes or rockets ends up costing 100 or 1,000 times more than a pipe and balloon," Hunt says. "At an altitude of 20 kilometers, an airplane can only carry one, maybe two, tons of payload. That means five to 10 million flights per year, burning roughly 1 percent of global oil production. It seems unlikely to me that that would be economically viable when a few dozen pipes would do just as good a job."
The current pilot program will pump 100 kilograms of water per hour to an altitude of one kilometer. Full-scale designs call for as many as 64 pipes spread around the world, each lifting five kilograms of sulfur dioxide or other reflective particles per secondapproximately 160,000 metric tons per year. Each pipe alone would weigh 30 tons and would be held aloft by a balloon 100 meters in diameter, slightly larger than the largest balloons ever built. The biggest challenge of all, however, would be developing a flexible pipe that can withstand ultrahigh pressures. To raise the particles to a height of 20 kilometers, the pipe would have to withstand 4,000 to 6,000 bar, or atmospheres of pressure.
It is a proven point that cold weather kills more people than warm.
So then, who is complaining about warmer climates?
Surely not the Vikings that were living in Greenland.
That is until things got cold again.
Perhaps it is all part of the population conspiracy.
That conspiracy preceded the acid rain, ozone hole,
global warming, climate change and a thousand other
scams by the radical control freaks of the world.
The ones that says too much population = bad.
Of course we know the definition of too much might just
be any, over and above those involved in the conspiracy.
Too many people with too much time on their hands. With
nothing to do but worry and fret about the state of the
planet. God help us, help ourselves.
They will need a volcano.............
I hope that they have a good heat tape wrapped around the pipe. I hear it gets a might chilly at 65,000 ft.
Good point !!! It will freeze in the tube¿?
At 39,000 feet, the last aircraft I was on, the outside temp a
was a brisk -100 degrees F......
Yes, a warmer planet does have many someones stupid ... and stupid is as stupid does ... as all know.
Think if population control is the main objective, a delivery system less expensive would be the method of delivery or maybe the thinking is ... this would be the cheaper delivery system? Unknown to me yet, maybe balloons would be quieter in the dead of night?
Think it would be better to back away from the keyboard, for me ... Starting to scare myself.
They want to pump sulfur dioxide into the air from 64 stations around the world?
Thirty years ago, the predecessors of these kooks were campaigning for pollution control equipment to keep sulfur dioxide out of the air.
Do they think that if they put this stuff up high in the air it will not work its way back down to us?
Do they think that the rest of the world will just stand by and let them poison the global atmosphere, for a scheme as hare-brained as this?
No one knows what will really happen if they do this. But they are talking about a global experiment, and failure will have global consequences.
Besides, the sun has had decreased sun spot activity in the past three years, and some scientists are predicting a little ice age. The Maunder minimum lasted something like 70 years. Anyone who was perceived to have helped bring such a spell upon the earth would be the subject of scorn, ridicule, and revenge.
My technical education is more than sufficient to understand both the theories and the evidence on both sides of the anthropogenic global warming debate. The result is that I am not worried about “man-caused climate change” hurting us. What frightens me is geoengineering. We may be totally out to lunch on AGW, but I am quite confident that geoengineering would drop global temperatures as much as predicted - the computations and technical challenges are so much simpler. The downside is that if the warming we are countering is fictional, instead of “saving” the world, we will push it into another ice age, and those can last for a very long time and do real damage. That sounds like something a liberal would do by accident, doesn’t it?
The road to a frozen Hell is paved with good intentions..........
These are just like the guys that seeded hurricanes with silver iodide back in the 60’s, in an attempt to ‘rain’ them out of energy.

Of course The Spice girls have nice balloons and could give a leg up to the program!
Yep, but everyone would be told, as always and as all know, the intentions were good. There would never be anyone who would be blamed for their "Good Intentions." How can anyone be or believe a liberal? Sheesh...
Always....always remember that the number 1 driving force for all liberals/Democrats/progressive/socialists is the fear that there are/will-be too many people on this planet. Killing people by freezing them to death, or starving them, is considered to be merciful euthenasia by Democrats.
5280 ft x 62.5 lb/foot^3 = 330,000 pounds/foot^2 ~ 2300 psiThey don't have those at Ace. Besides which, the hose has to be able to support the weight of a mile long hose filled with water. The higher you go, the worse it gets.
and a pump that can develop that kind of head pressure.
...and it’s gonna freeze when it gets to the top..........
I’m not sure what is most pathetic - that a nation would attempt such a laughable project or that a magazine entitled “MIT Technology Review” would bother to cover it(???)

A Crop Duster would work better.........
Attention Hugh Hunt and other idiotic British researchers: It’s not note to screw around with Mother Nature.
