Sorghum in your gas tank?
Another route to decreasing reliance on oil is biofuels. Agrivida, which is based in Massachusetts, is a biotechnology company trying to develop "energy crops" specifically for making fuels. Its goal is to engineer a plant that containa an enzyme that will aid in the process of breaking down cellulose into sugar. Pictured here is sorghum, one of the grassy plants such as switchgrass, being tinkered with to make fuels.
