I had a quick peak at a boat called Earthrace today - a bio-diesel powerboat that's currently touring the globe. Visually stunning, it certainly lives up to its billing as "the world's coolest boat".

It goes very fast. Oh, and it's powered by bio-diesel.

Whether you regard biofuels as an environmental solution or not, it's definitely one nice-looking boat, as this picture shows.

Sydneysiders can see it in Circular Quay in Sydney until January 11th then making its way around the coast to the Melbourne Boatshow on January 30-February 1.
