The folk I know who use biofuel to run their deisel vehicles all filter
used vegetable oil retrieved from cafes etc. In this context I think its
a great way to recycle these waste products - there must be massive
amounts of waste frying oil from all the fast food store, restaurants
etc. But growing annual crops specifically for running motor vehicles is
not a solution to fossil fuel alternatives.

Alternatives....?
Biogas - there's a fleet of taxis in Adelaide running on biogas retreived
from land fill sites.
Hydrogen fuel - Browns Gas - Yule Brown developed a safe way to separate
Hydrogen from water and implode the hydrogen molecules to release energy
- he drove a car from Sydney to Cairns in the 1980's on 1 liter of water!
I edited an article about this for PIJ in the early '90's and a friend
wanted to follow it through but Yule Brown couldn't be found (gone
underground? otherwise eliminated? who knows...) I think this might be
one of the fuels of the future but the oil industry wouldn't want to see
it too poplular too soon....
