Actor Kevin Costner's company claims his device can suck 2,000-5,000 gallons of oil a day.
He says they have have about 40 machines already made. If BP likes what they see during the demo, they say they'll make plenty more.
The video above shows relatively clear water being sucked out of oil. They say the water has less than 1 percent oil.
In the video, you can also see Costner chatting it up with Jefferson Parish councilmen Tom Capella and John Young, Plaquemines Parish President Billy Nungessor and St. Bernard Parish President Craig Taffaro.
