Truth really is stranger than fiction, and this story that I would swear came from The Onion (but apparently didn't) is proof:
Enter "Waterworld" star Kevin Costner, who has invented a device that cleans oil from sea water.
British Petroleum - desperate for ideas – gave the okay to test six of Costner's gizmos Wednesday, after the Army Corps of Engineers gave the machine a thumbs-up.
Costner's $24 million centrifuge machine has a Los Angeles-perfect name, "Ocean Therapy."
Placed on a barge, it sucks in oily water, separates out the oil and spits back clean water.
