Sorghum for fuel?

Oil prices are affecting everything in this day in time.  People have to do without some things they took for granted just last year so they can have the gas to go to work now.  The solution is not a simple one but I do believe that alternative sources of fuel are the key to help combat the ever rising price of gasoline.  I saw where they can use sorghum (which is what a lot of our ancestors used to make molasses) to produce a cheaper fuel.  This would also help keep food prices down and feed a lot of families.  I’m sure someone will find a way to poo-poo this like everything else to help bring down our dependence on oil.
