Who do you think would be the best celeb to publically endorse biofuels and put them firmly in the public's eye.
Here's my top five
1. Willie Nelson: Bio Willie great name for a product
2. Daryl Hannah: Lots of fancy celeb friends to convert
3. Al Gore: Made a film, talks at length
4. Richard Branson: A one-man Brand. Is he riding the wave or making waves?
Help me out. I need more names for a top ten.
