The Q4000, foreground, burns off oil and gas at the BP Deepwater Horizon blowout site in the Gulf of Mexico July 10, 2010, while a relief well is drilled behind it. BP is changing the device capturing oil from the leaking well and plans to have a new, more efficient device in place in seven days, though in the meantime oil is gushing unchecked from the well.
