Kevin Costner, star of Waterworld and other epics, has been called in by BP to help clean up the oil disaster in the US Gulf.
Costner has patented a stainless steel device called the Ocean Therapy which cleans oil from tainted seawater. The actor has spent 15 years and $26m on developing the machine which sucks up dirty liquid and then uses a high-speed centrifuge to separate it into oil and heavier water, according to this article which Truong pointed out, and many others like it in the international press today.
When the water and oil are separated, which one gets stuck with the dispersant?
