In this Q&A with the Wall Street Journal, Craig Venter, who has recently partnered with ExxonMobil and BP, says that it will be at least 10 years until you have gasoline made by synthetic organisms in your car's tank. "Scalability is the biggest issue," he says. "If we can't generate billions of gallons of fuel per year per facility, it's not going to work. But I think with the Exxon engineering team and their money, we have a chance to scale it up." With BP, Venter is "[looking] for new biology deep in the Earth, to take coal as the starting material, metabolize the coal into methane in the Earth and just isolate the natural gas."
