The internal combustion engine revolutionised transport in the 20th century. It now seems almost certain that the fuel cell will do the same in the next 100 years.
A new study concludes that the official tests which measure the emissions and fuel consumption of new cars are not an accurate reflection of today's real world driving conditions in Australian cities.
While it's rarely cited as a factor behind Australia's booming new car sales figures the rising price of petrol has probably caused many people to get out of their thirsty old banger and into a new car that´s smaller and more fuel efficient.
Rising fuel prices and a growing awareness of the environmental effects of greenhouse gases means that car manufacturers are looking for alternative fuel sources.
It seems that the days of 80-something cents per litre are now probably a memory. While diesel is seen by many people as a more cost efficient alternative, the cheapest fuel continues to be Liquified Petroleum Gas - LPG.
