Kevin Costner and a group of scientists, including Costner's brother Dan, demonstrated the $24 million dollar machine that uses centrifugal force to separate oil from water in New Orleans earlier this week, hoping to convince BP that it can be used to clean up the oil spilling from the Deepwater Horizon rig. The "Ocean Therapy" machines use centrifugal force to separate oil from water, and have a success rate of about 97%. Ocean Therapy Solutions spokesman John Houghtaling said the resulting water was even good enough to drink!

BP said they were working with Ocean Therapy to decide where to test the machines, but if all goes well the machines could be at work cleaning the gulf within a week.
