One of the many firms that is working on a replacement for oil is LS9, this Silicon Valley company is experimenting with genetically altered bacteria that create renewable crude oil from agricultural waste. This oil is "carbon neutral" and will be fully compatible with our current infrastructure.
The closest that LS9 has come to mass production is a 1,000-litre fermenting machine, which looks like a large stainless-steel jar, next to a wardrobe-sized computer connected by a tangle of cables and tubes. It has not yet been plugged in. The machine produces the equivalent of one barrel a week and takes up 40 sq ft of floor space.
However, to substitute America’s weekly oil consumption of 143 million barrels, you would need a facility that covered about 205 square miles, an area roughly the size of Chicago.
That is the main problem: although LS9 can produce its bug fuel in laboratory beakers, it has no idea whether it will be able produce the same results on a nationwide or even global scale.
“Our plan is to have a demonstration-scale plant operational by 2010 and, in parallel, we’ll be working on the design and construction of a commercial-scale facility to open in 2011,” says Mr Pal, adding that if LS9 used Brazilian sugar cane as its feedstock, its fuel would probably cost about $50 a barrel.
Are Americans ready to be putting genetically modified bug excretion in their cars? “It’s not the same as with food,” Mr Pal says. “We’re putting these bacteria in a very isolated container: their entire universe is in that tank. When we’re done with them, they’re destroyed.”
