Gulf Leak Much Larger Than Reported?

Matt Simmons, a well-known oil industry analysts, says there is a much larger and leak nearby.  He says the other leaks have plumes that indicate leaks of over 120,000 barrels per day.  He also says the Soviets over the past 30 years have had huge well leaks and had stopped the weeks by detonating nuclear weapons a couple miles into the well to seal in the well.
