You have a better chance absorbing an olympic size swimming pool with a kitchen sponge.
You'd not only have to control the storm, but all the highs and lows around the storm. If you dump millions upon millions of pounds of absorbant material...all it takes is a small warm current a few miles wide to regain a hurricane's strength.
Ivan is a hurricane. It's simply a large body of moving water and rain that's basically just nature balancing itself out. Humans attribute cause and effect where really it's just nature just doing her natural work. It's not controllable. Hurricane forecasters at the National Hurricane Center have enough trouble predicting a hurricane...but maybe someday we _could_ control it. The guy has good intentions, but practically it's not feasible.
