GE Microbes Make Ersatz Crude Oil From Many Sources
polymath69 writes "According to The Times Online, genetically modified microbes have been developed capable of turning surplus material such as wood chips, sugarcane, or others, not into ethanol, but into a substance which could substitute directly for crude oil. They claim it could be sold for about $50/bbl, and the production process would be carbon negative."
The process is likely to work, though scaling up may be a problem, but they're very unlikely to have the field to themselves.
There are a lot of companies looking at similar ways of producing fuels. Sapphire Energy claims to be able to make 91 octane gasoline directly from sunlight, CO2 and algae.
Many fringe energy sources have become cost competitive with geological oil since it more than quadrupled in price. What will be interesting is how the oil giants respond to this competition.

This technology has been around for awhile although biofuels usually produce ethanol. Just a molecular side chain away from what these guys came up with. They get 1 barrel from 40sq feet of space. At our current rate of 143 million barrels a week it would take 205 sq miles of manufacturing plants to satisfy our current needs. About the size of Chicago. Probably about the same square footage it you total up all the Walmarts. Very doable.
They got us here in spite of all the government roadblocks. IMHO we would have got here a lot sooner if we hadn't laughed Gore off the stage and I suspect progress will increase exponentially when Obama takes over.

Tangentially, you may be interested to know that when the post office was going to murder all of us with anthrax and the media was trumpeting on about how Cipro was our only hope, a quick look at a the literature revealed that doxycycline is both 1) equally effective and 2) no longer covered by patent and about a hundred times cheaper.
I have mod points. The reign of terror begins now.
There are a number of biomass-to-fuel technologies in the prototype to production stage, many of which have been featured on Slashdot in the past. Here's a sample:
Changing World Technologies (http://www.changingworldtech.com/) -- high-pressure non-catalytic conversion of biomass to Diesel fuel -- prototype online in Missouri
Range Fuels (http://www.rangefuels.com/) -- cellulose -> syngas -> blended alcohol -- proven, 20-million-gallon/year plant under construction in Soperton, GA
AlphaKat (http://www.alphakat.de/) -- biomass/plastics -> Diesel fuel via metal-catalyzed high-temp, high-pressure reaction. Plants under construction across Europe
MagneGas (http://www.magnegas.com/) -- sewage(!) -> natural gas + surplus heat via electrolytic conversion -- you can buy or rent a working production unit from their web site
I note that all of the above use a high-temperature, high-pressure reaction process to produce fuel. The GE process has the advantage over the first three in that it can handle water better than the first three processes above (IIRC, most Fischer-Tropsch type plants have a low tolerance for water in the reaction vessel, which is bad for biomass conversion unless you spend energy to dry it first. E.g. AlphaKat says their process doesn't work with more than 12% water by weight). The other major advantage is that fermentation typically occurs under more gentle and manageable conditions, i.e. near room temperature, near atmospheric pressure and aqueous rather than solvent/metal-catalyst based. However, the down side of their process is that it's not self-contained and not truly carbon-negative unless you use plant biomass as a feedstock, though if you grew algae in an adjacent tank you could probably use that as your feedstock and harvest CO2 from the air. Actually that would be an ideal solution because you could genetically tune your algae to have a specific composition and tune your fermenter bacteria/yeast to efficiently break down your algae. Hopefully that will be in the next phase of this project. Though we'll probably have to make do with catalyst- and pressure-converted biomass until these guys can perfect their process.
