The numbers back up some of Costner's complaints: The oil industry spends only $40,000 per year on oil spill research and development.
Still, while many ideas have been posted on the Web and shared since the start of the crisis, plenty of products that promise solutions don't actually stand up to scrutiny.
Today, ABC News saw a sponge that failed to soak up oil.
And then there's Earthbound Green's kitty litter, which was demonstrated for our cameras today. It does soak up the oil, but covering the entire spill with the product could cost tens of billions of dollars.
"The types of cleaning techniques and oil removal techniques have been used for more than 40 years in large part because these are proven technologies that do work," said Tony Wood, director of Texas A&M's National Spill Control School.
Some new techniques have made it into use, including skimmers provided by the Netherlands and the vacuum system now sucking oil from the marshes.
However, it seems that with thicker oil now rolling up on the wetlands and beaches, there will be no easy fix -- just months of hard work.
