Another great development in bio-fuels I heard about from Green Options is called “Greaseball Challenge.” It seriously doesn’t get much cooler than this: the Greaseball Challenge is a race from the USA to Costa Rica in vehicles running strictly on renewable fuels. And it’s a charity benefit. Their site describes the challenge:

The Greaseball Challenge is a charity biofuel car rally
from the USA to Central America. Inspired by the tradition
of the classic car race, Greaseball is a cross-continental
adventure promoting sustainability on a shoestring using
renewable fuels.
The inaugural Greaseball Challenge departs on April 1, 2007.
Armed with nothing but a sense of adventure and some
cheesecloth, five teams will drive 4,500 miles on grease power
from the USA to Mexico, Guatemala, Honduras, Nicaragua
and Costa Rica.

I am so tempted to sign up for this thing! It’s fun to watch the racers’ progress on the Greaseball Challenge blog and live on the road vicariously. I’ve always wanted to drive down to Peru, I might just have to copy these Greaseballs and follow their route…
