From Jalopnik - 

Laugh you may have when you heard that Kevin Costner was stepping into BP's oil spill disaster with a potential solution, but BP has now snapped up 32 of the centrifuge machines to help separate the oil from the water.

The technology was created by Costner's brother, with the actor pumping in $20m over 15 years. While 40,000 barrels worth of oil is leaking into the gulf of Mexico each day, the V20 machine can clean up 200 gallons of water a minute.

Horrendous the spill disaster may be, but it's terrific well-known personalities such as Costner and James Cameron are leaping forward with possible solutions to clean up the gulf. [ABC via The Guardian]
