Chat with experts about the world’s fuel future. 
How long before the world starts running short of oil? Have we hit 
the peak of oil production already, or do we have until mid-century, as some optimists predict? 
This week on ScienceLive, join a live chat with two experts on oil as
 a critical energy source: Mark Finley of BP and David Greene of Oak Ridge National Laboratory. They’ll answer your questions on a variety of
 pressing questions, including whether hot new technology can boost 
world production, how the United States might reduce its dependence on 
foreign oil, and the biggie, how much breathing room we have before the 
inevitable peak.
