"THE Australian car industry needs serious investment in alternate fuel technology and hybrid cars, experts have warned, after the US carmaker Ford posted record losses yesterday."

I think public transport and plug-in electric bikes and cars are the way to go in the city. The later can be charged at home and at parking stations.
For longer trips (cars, buses, trucks, trains, ships) biodiesel from algae, Chinese tallow, palm tree oil etc is a solution.
Algae can be grown near power stations to use up half the CO2 emissions, and at sewerage works. Chinese tallow is a weed in coastal USA and around here but the seeds can be made infertile. Palm oil can be grown in northern Australia provided it does not replace food crops or forests.
