Kevin Costner may hold key to oil spill cleanup

The " Kevin Costner solution" to the worsening oil spill in the Gulf of Mexico may actually work. Costner has invested 15 years and about $24 million in a novel way of sifting oil spills that he began working on while making his own maritime film, "Waterworld," released in 1995.
Costner bought the technology, which was originally developed with help from the Department of Energy, after the 1989 Exxon Valdez disaster and turned it over to a team of scientists and engineers for fine-tuning.
The machines are essentially like big vacuum cleaners, which sit on barges and suck up oily water and spin it around at high speed. On one side, it spits out pure oil, which can be recovered. The other side spits out 99% pure water."
