From the Daily Mail:
Scientists make diesel fuel using sun, water and carbon dioxide
Scientists have genetically engineered an organism that secretes diesel fuel wherever there is sunlight, water and carbon dioxide.
Biotechnology company Joule Unlimited claims it can produce diesel fuel and ethanol on demand at unprecedented rates.
Researchers at the firm, based in Cambridge, Massachusetts, said they can produce the fuel that runs jet engines using the same ingredients that make grass grow.
They also claim to be able to make it in facilities both large and small and at costs comparable to the cheapest fossil fuels.
Joule's website describes the breakthrough as 'energy independence', although many remain sceptical.
Chief executive Bill Sims said: 'We make some lofty claims, all of which we believe, all which we've validated, all of which we've shown to investors.
'If we're half-right, this revolutionises the world's largest industry, which is the oil and gas industry.
'And if we're right, there's no reason why this technology can't change the world.'
Wet blanket alert!
But National Renewable Energy Laboratory scientist Philip Pienkos said Joule's technology is exciting but unproven, and their claims of efficiency are undercut by difficulties they could have just collecting the fuel their organism is producing.Timothy Donohue, director of the Great Lakes Bioenergy Research Center at the University of Wisconsin-Madison, said Joule must demonstrate its technology on a broad scale.
Perhaps it can work, but 'the four-letter word that's the biggest stumbling block is whether it "will" work,' Mr Donohue said.
'There are really good ideas that fail during scale up.'
Mr Sims said he knows 'there's always skeptics for breakthrough technologies'.
