Two decades after the Exxon Valdez oil spill, cleanup technology has progressed so little that the biggest advancement in the Gulf of Mexico disaster — at least in the public’s mind — is an oil-water separator based on a 17-year-old patent and promoted by the movie star Kevin Cosner.

Controlled burns of oil — only tested in 1989 — have been conducted regularly in the gulf.
