The cloud seeding only works when there are clouds with enough moisture in them to seed. It's not magic, you can't conjure up biblical amounts of rain out of nothing. That water has to come from somewhere. In the Southwest of the United States that water comes from water evaporating from the warm seas off the coast of Mexico. If you can get enough water to evaporate to form rain clouds, you still have to keep the air hot enough that it stays evaporated and doesn't fall somewhere that you don't want it to fall. Then there's the issue of getting the wind to blow it where you want it to go. How the fuck are you supposed to control the wind? The answer is you don't. You just have to rely on the same wind currents that have always been there. So theoretically, you could possibly drop something really really hot into the ocean upwind from where you are hoping to get rain. Then it's just a matter of waiting for the clouds to blow over where you want your rain and then you have a guy fly around with a plane seating the clouds with a chemical that makes the water condense or cools it off so that it'll condense.
