Cleanup crews still face the challenge of getting rid of the millions of gallons of oil that have been flowing into the Gulf of Mexico since April. Some of the most fouled water is being cleaned by separating devices known as centrifuges. American actor Kevin Costner has been funding the development of this technology since the Exxon Valdez disaster off the Alaska coast in 1989, but the machines have never been used to clean up an oil spill—until now. Host Steven Cherry talks with Eric Hoek, an engineering consultant for Costner’s Ocean Therapy Solutions, about how the company’s centrifuge technology is cleaning up the Gulf.
