BP doesn't know if mystery plumber figured out fix for gusher

There's a story going around about an anonymous plumber who sketched this fix and send it to a Cal Berkeley professor who looked it over and forwarded it over to BP. Here's hoping this turns into a real feel good story, the plumber gets his/her moment in the sun and gets REMUNERATED by BP for his suggestion.

Six weeks ago, Robert Bea, an engineering professor at the University of California, Berkeley, received a late-night call from an apologetic "mystery plumber." The caller said he had a sketch for how to solve the problem at the bottom of the Gulf. It was a design for a containment cap that would fit snugly over the top of the failed blowout preventer at the heart of the Gulf oil spill.

Professor Bea, a former Shell executive and well-regarded researcher, thought the idea looked good and sent the sketches directly to the US Coast Guard and to a clearinghouse set up to glean ideas from outside sources for how to cap the stubborn Macondo well.

When Bea saw the design of the containment cap lowered onto the well last week, he marveled at its similarity to the sketches from the late-night caller, whose humble refusal to give his name at the time nearly brought Bea to tears.

"The idea was using the top flange on the blowout preventer as an attachment point and then employing an internal seal against that flange surface," says Bea. "You can kind of see how a plumber thinks this way. That's how they have to plumb homes for sewage." 

  True to character, BP claims they really aren't sure where the idea originated, who was responsible for using it, that their guys probably thought of it first anyway and they couldn't see any reason to find that guy and give him some money unless, of course, he had the right papers.
  Amazingly, the professor isn't trying to claim it was all his idea and that he'd like an enormous government grant to conduct more research on this very item and its future in the industry.
  Yet.
