I came across this site today about a Japanese guy driving a 100 Series Landcruiser with a 1HD-FTE around the world on bio made from a small processors that fit inside the vehicle.

He started out in 2007 and seemed to make it across North America, but there are no entries for the next leg, Europe - last date on the route map was 25/04/08.

Does anyone know if he ever made it?

What a great project.
