I don't see how cost effectiveness plays a part in this, really. I don't care how much it costs BP to clean this mess up. If they were to find diamonds are the most effective means of removing oil from water then I expect BP to spend every last penny mining diamonds until the gulf is clean, even if the CEOs have to sell their watches to fund it.
As for the hay shortage I'll say 2 things: 1.There are many different types of hay that can't be used as animal feed that could possibly used in this situation and 2. You said "nationwide" hay shortage. BP can buy it somewhere else and bring it over. Don't tell me they'll go bankrupt, we're talking about a HUGE oil company with MEGA deep pockets.
About the below surface oil - how about encasing the hay in something like a giant mesh pillowcase and using weights to suspend it below the surface into the current for a while, then picking it up with ships. Kindof like a giant lobster trap, only on a larger, more sophisticated scale?
