Cloud Seeding - A Real World Rain Solution?

In the world of today, it is not uncommon to hear of famine and drought. Africa and Australia are no strangers to these two phenomena. For me there is only one real explanation: a lack of water which is the result of a lack of rain. For years now, climatologists have researched and experimented with weather modification. A process which has become distinctly more advanced over the last decade is known as Cloud Seeding.

Cloud Seeding is an attempt to change the amount of precipitation that falls from clouds. This is done by dispersing substances into the air onto which water vapor condenses. These dispersed substances act as ice nuclei for raindrops. Basically, the process plants "rain seeds" into clouds in order to increase precipitation.

Cloud Seeding can be done by ground generators, plane (most effective) and rocket (not shown in diagram)

The most common chemical used for Cloud Seeding is silver iodide. This silver iodide is released into the air from flares attached to a planes wing. From here on the process of precipitation should take care of itself. In essence, Cloud Seeding is simple but hasn't yet been applied on a very large scale. The process tends to focus on specific areas rather than entire regions.

There has been dispute to exactly how effective Cloud Seeding is, but one thing is certain: it works! The effectiveness seems to depend on the region and cloud. The amount of precipitation due to seeding is also difficult to quantify. Cloud Seeding has been more effective in some instances than in others. I believe that Cloud Seeding needs to be fully research as it seems to be a way of combating drought or at least rain shortage. Cloud Seeding has already come a long way since it's concept first originated in about 1940.

I think that Cloud Seeding is a simple procedure that is a very plausible solution to rain shortage. Could it be THE solution? Could there be ways of reducing precipitation during times of flood with a similar process? I'd love to hear what you think!

I was just this very moment wondering about this very thing! I am loving the Evoke synchronicity and really appreciate your post! It seems with all of the technology that has been developed that harms the environment, this potentialy positive technology should be pursued with vigor!

Thanks :)..and yes you're right! So often we see some fantastic new technology developed, only to discover that it does more damage to the environment than it helps! Cloud Seeding doesn't seem to have any negative effects on the environment. I definitely agree that it should be pursued with vigor!

Some people want to use this technology to prevent precipitation as well. Check it out here.

Thank you very much :)..the possibility of being able to fight rain induced disasters (mainly floods) is something that should be explored!

Just love it! Here I am thinking of growing plants in controled envorinments and you blow my mind with cloud seeding. If I could give more than 1 Evoke point I would!

Man thats amazing. You should definitely be higher up in the ranlings. This is a real world solutoin to a real world problem. +1 Vision.

Incredible stuff....!! I heard this being mentioned a while back but thanks for putting this into perspective :) good stuff buddy

Great innovative idea, This is a great blog and a real life solution to areas that suffer from drought :) great work agent dyer!

Its a good idea, does it contribute too much salt to the water it produces?
Comment by Martin Dyer on April 15, 2010 at 2:22pm
I don't think so but can't be sure. farmers themselves have adopted this system to help better their crops and I'm sure they wouldn't do it if it over-salted their rain water. it's a very good point though and is something that has to be considered :)

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal.

All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
