http://www.dailymail.co.uk/sciencet...-Scientists-convert-plant-crude-oil-hour.html Drivers could soon be filling their cars with petrol created using algae thanks to a new process that converts the organisms into crude oil in less than an hour. Engineersat theU.S. Department of Energy's Pacific Northwest National Laboratory (PNNL) have created a chemical process that produces useful crude oil minutes after they pour in harvested algae - a verdant green paste with the consistency of pea soup. ... 'Cost is the big roadblock for algae-based fuel,' said Douglas Elliott, the laboratory fellow who led the PNNL team's research. 'We believe that the process we've created will help make algae biofuels much more economical.'
