Dynomat corporation has developed a very absorbant powder which they have proven that if it dropped into clouds, it will dry them out.
You can research dynomat on metacrawler search engine and read about their weather modification research.
I think that this powder could be dropped into the clouds at one end of a tropical depression, before the circulation closes, and dry out one end of the tropical depression. This would prevent a circulation from forming and prevent it from becoming a tropical storm. That would prevent hurricaines from occuring.
Planes could be stationed, in hurricaine season, on an island off the coast of Africa and in the Carribean, to be ready to seed the tropical depressions as they are forming, and prevent them from becoming tropical storms.
This may only need to be done 10 times or less, each hurricaine season.

Dry them out? Where is the evaporated water going? Wouldn't it just make more clouds? =\

Rain.

Clouds are made of ice crystals and very small water droplets. The powder hits the cloud and it forms a transparent gooey mess that falls from the sky. It destroys clouds.

Click on the research projects section also. There might be more details there.
They said they cut a cloud in half with a crop duster.

how hazardous, if at all, is this powder dynamat has created?

That sounds a little to good to be true or safe, like serin gas....

Spending more money to stop the hurricanes compared to the cost of damage they will cause is not a good idea.

Was that a question?

too true.

how much is a human beings life worth?
