Oh Snap! Now some German scientists have (in effect) taken a swing at Stanford professor Mark Z. Jacobson, who concluded in a recent paper that biofuels are a bad policy direction (see summary post here).
In their paper , Prof. Jürgen O. Metzger from Carl von Ossietzky University of Oldenburg in Germany and Prof. Aloys Huettermann from the University of Goettingen in Germany say that growing and using biofuels for all the earth's energy needs is not only possible without jeopardizing the global food supply, but also economically feasible.

According to , researchers in Italy have figured out how to turn olive pits into fuel:
Olive stones can be turned into bioethanol, a renewable fuel that can be produced from plant matter and used as an alternative to petrol or diesel. This gives the olive processing industry an opportunity to make valuable use of 4 million tonnes of waste in olive stones it generates every year and sets a precedent for the recycling of waste products as fuels.
