28 November 2012 — The winner of the Nobel Prize in Chemistry in 1988 for work on photosynthesis, Dr Hartmut Michel, says bio-fuels don’t work. The director of the Molecular Membrane Biology department at the Max Planck Institute for Biophysics offers three reasons for his logic. Firstly, Dr Michel says photosynthesis is inefficient because plants only convert about 1 per cent of the sun’s energy into chemical energy. So that’s out. Secondly, turning biomass into bio-fuels is also inefficient because of the energy needed to grow fields of plants. And finally, creating bio-fuels would also use up large quantities of arable land and food, degrading soil and putting pressure on food prices. Read the full story here.
