Read a book by David Suzuki (he didn't make motorcycles) about energy and food.
He pointed out the calorific content of a lettuce, and how many calories were consumed air freighting Oz lettuce to France so people could eat salad all year around.

If we have to import biofuels (in particular the seeds for the oil), then the entire reason has been defeated.
Tony had the right idea.
Fuel from locally available, already used oil is the way.
Wonder what the fossil fuel useage is to transport 57,000 tonnes of canola seeds across the world.

Cargill Australia has imported 57,000 tonnes of Canadian canola to supply oilseed and biodiesel industries. The current crop estimates are 160,000 tonnes in eastern states, while demand is running at 500,000 tonnes.
