  • Biofuel of the day #1: pig poo. A team at North Carolina State University has developed a process to convert swine waste into bio-oils, using ethanol as a solvent. “Tremendous energy potential”, apparently (Green Car Congress).
  • Biofuel of the day #2: miscanthus grass. A second project at NCSU involves the breaking down of the tough woody stalks into a carbohydrate-rich solid, with no waste, using ozone. The treatment process results in a “commercially viable feedstock for biofuels, curtailing biofuel’s reliance on staple food crops”, says a spokesman (Green Car Congress).
  • British firm Aeristech has secured ¬£500,000 of funding to support the development of its hybrid turbocharger technology. Its separate motor-driven compressor and turbine-driven generator units, electronically integrated, are said to eliminate delayed response (turbo lag) and will allow for “aggressive engine downsizing” (Green Car Congress).
