Proculation Proculation:
BP doesnt want to close that well. They will loose billions. So they are trying to reduce the damages until they have another rig to pumb the oil.
BP
can't close that well -- there are thousands of pounds per square inch force coming out of that well, and we are working at depths where it is incredibly difficult to even control the depth of something. They are losing billions by having it
open.
Trust me, if BP wanted to save money, manpower and save face, they would have capped it loooooong ago if it were up to them, but it's not -- it simply cannot be capped, the pressure is to powerful for any free floating or moveable apparatus to successfully contain the vast amounts of pressure being exerted at the very opening of that head.
As for the other methods, I believe the problem is that we are beginning to talk about bioremediation. This is actually a very serious problem which occurred during the last oil spill is that the bacteria just don't die when you are done -- they keep going, and going, and going, and when the creator of these materials say that it targets hydrocarbons, my first thought is "okay... so when does it stop? What else does it consume? What if the bacteria migrate as chemoautotrophs will do into the actual oil source? Can we remove them afterwards? Will we create another problem altogether by introducing these bacteria into this region?"
