Storm Experts Make Cloud Vanish 19
ianchaos writes: "According to an article in New Scientist, storm experts in the U.S. have made a cloud vanish from the sky for the first time. They achieved the feat by sprinkling a water-absorbing powder over the cloud, making it disappear from sight and weather station radar screens. They hope the powder will one day dry up deadly hurricanes and tropical storms."

They were stopped because of protest from other countries who did not appreciate the US fiddling with the global climate.
Not likely to be much different this time around.

First of all, let's just make clear that the scalability of this project will be a problem. Just because you make one little cloud disappear does not mean you get to take away hurricanes.
Next let's discuss the climate issues. Water is recycled on this planet. Any fourth grader can tell you about the rain cycle. Start mucking about with chemicals trying to absorb water and you will eventually muck about with the world's water. A better solution would be for people not to live in places very prone to hurricanes, or for people to adapt dwellings, etc. to withstand them.
Third, let's talk about the physical uselessness of this project. Hurricanes are extreme low-pressure areas. Anyone who's taken high school physics can tell you that the natural movement of anything (atoms, etc.) is from an area of high-pressure to an area of low-pressure (this is why champagne corks pop and why they tell you not to puncture aerosol cans). You may be able to withdraw the moisture from the atmosphere (see the second point above), but that will not necessarily remove the area of low-pressure. Water (in the form of clouds) will continue to gravitate toward the low-pressure, thus patching up all the "holes" that this ridiculous powder would be creating.
Fourth, the price of sporting events is high enough already without having to pay for cloud dispersal services.
Fifth, we already have something that absorbs water and moisture. It's called silica gel, it's horrendously poisonous, and it comes in packets in every box of electronics shipped on this planet.

I'd have to agree.
Same goes for forest fires. The forests were fine for millions of years without us running around putting out fires. Now we just let fuel build up until we get these super-fires we've been seeing in the last few years.
I'd rather they quit spending money on fire-jumpers and just make those people who build their house in the woods pay for fire insurance.

Maybe it could work, but I'm very skeptical that it would have much of an impact unless it was applied very early in the formation of a storm system, and as another poster noted, very much of that would probably have some environmental consequences.

They say it disolves in salt water, but there's not likely to be much salt water at your average stadium, so the stuff might be around for a while. And what would a "gelstorm" do to the traction on a football field or racetrack?
The primary use, over the ocean, sounds interesting, but frankly I think the mention of killing clouds over sporting events is just a little sensationalism to raise hype.
Hurricanes have uses, too. (Score:4)
First off, let me say that my heart goes out to those who have suffered damage or the loss of the life of a loved one because of a hurricane.
As an example: Years ago when hurricane Gloria came through my area, I was without power for 4 days and had friends who had no power for a week. Many roads were closed because of fallen trees. It was a real mess.
But, I noticed something else. For the next few years, the usual storm-related power outages ceased. The big storm cleaned out all the deadwood hanging over power lines. Only the really strong and healthy trees and branches remained.
I like to take walks in the woods. I noticed that the fallen tress and branches became natural habitats for wildlife. There were also great openings in the canopy where trees had once been -- this brought more light down to ground level and caused an outburst of low-level shrubs and the like. It seemed like Darwin's Theory of Evolution at work on a grand scale - a wholesale wiping out of the weakest leaving only the strong to survive.
The point I'm trying to make from these few examples is that I caught a glimpse of what I believe to be long-term cycles at work. I suspect these huge storms are as important to our ecosystem as regular storms are.

the water cycle is not harmed in any way (as if it could be)
It sure could be. If every time a tropical storm develops, we crush it in its infancy, a huge amount of water will fall - on the ocean. This water will not travel to wherever it's going, and the weather patterns of wherever these storms are will change. Look what happened to the Sahara - it's not too hard for local climates to change drastically in response to weather change. If Cuba doesn't get as much moisture falling out of the sky because it was all dumped in the middle of the ocean, their sugar cane will die and -bad things- will happen.
It's not worth considering such a drastic use for this technology until we know more about the weather.

As for hurricanes, their theory has yet to be proven, but the idea is to drop this stuff in a straight line from the eye out to the edge, thus disrupting the hurricane enough to turn it back into a tropical storm -- maybe even a tropical depression. Yes, the low pressure area will remain, but the theory is that the high winds will not (the high winds are not caused by high pressure air rushing radially into the low pressure storm).
And finally, this is not silica gel. Just because "we already have something that absorbs water and moisture" doesn't mean anything else that absorbs water is worthless. Do you wipe up coffee spills with silica gel? No. Do you pack electronics in paper towels? No. Do you read the damn articles before you post? Apparantly Not.

Well, I wouldn't want to swallow something that would dry the hell out of my GI tract. Painful.
Also, why is silica gel even packed with electronics? Most electronic devices can be completely submerged in water, and as long as you give them time to completely dry out, they will work fine, so what does it matter if a little moisture gets on the outside of a device from condensation?
Probably to guard against the people who won't wait till it dries out, but just plug it in immediately.

What have you been smoking? Silica gel isn't even slightly poisonous. Breathing a lot of it can cause lung problems, but that's true of any dessicant, for obvious reasons.
