This weeks podcast continues the series on biofuels, and spotlights
ethanol fuel as a replacement for gasoline. Brazil has replaced their
gasoline economy with ethanol from sugarcane. Here in the USA we have
many crops that can be used like corn, potatoes, sugar beets, etc. Any
sugar or starchy crop can be used. Hear more on our podcast, and
follow the additional informational links on making and using ethanol.

While ethanol is cheaper than gasoline it packs less energy per liter
so the miles per gallon is less. IIRC the USA bans the importation of
ethanol from Brazil. Flexfuel vehicles ( vehicles which use E85) and
the sale/distribution of E85 has not taken off in the Washington DC
area (Maryland, Virginia, and DC)  its more popular in places like
Iowa which grows alot of corn and is the beneficiary of corn base
biofuel government subsidies and programs.
