The search for a viable alternative to fossil fuels has been ongoing for many years. Our oil reserves are not unlimited, and the question of "what to do when the oil runs out" has been hanging in the air like exhaust fumes from a diesel engine.

Consequently, the search for new and innovative ways to create biofuels is an area of research that is receiving global attention and plenty of funding, and scientists believe that they have found a viable answer to the world’s long-term fuel requirements.In a ground-breaking study, researchers at the U.S. Department of Energy’s Pacific Northwest National Laboratory in Richland, Washington have managed to condense a fossilisation process that normally takes millions of years into just one hour.

While we’re all trying to figure out what is the best fuel to burn in our cars, some unexpected sources have turned up with some surprising ideas.

BBC News reports that in the UK, McDonald’s restaurants (which have been strongly criticized in Europe for encouraging the obesity epidemic there) has agreed is to convert all its delivery trucks there so that they run on biodiesel, which will be made from their USED COOKING OIL.

No used cooking oil around?why not run your car on fruit? Also in BBC News, Matt McGrath writes that researchers say that the sugar (fructose) in ordinary fruits can be converted into a fuel for cars that has LOW CARBON EMISSIONS.

There would be no oil shortage if we could use our coal, since we have LOTS of it. But burning it releases greenhouse gases, and what we need most is a clean way to power cars.

Researchers Burt Davis and Rodney Andrews are exploring ways to increase the efficiency of converting coal to liquid fuel. Davis says, "North America is one of the world’s largest coal-reserve regions. Its petroleum is declining, but coal is still the largest resource. If the United States is to become independent from foreign sources of petroleum, it has to make it from oil shale, coal or both. We have about equal amounts of reserves of oil shale and coal, at the current rate of usage, to be able to generate petroleum substitutes for the United States for the next 200 years."

Six years ago, Dreamland co-host Jim Marrs said, "It’s all about oil." Now the Australian defense minister says the same thing about Iraq.

In the Independent, Kathy Marks reports that the Australian Defense Minister Brendan Nelson "admitted that oil was a major factor in the government’s decision to keep troops in Iraq" in an interview on the Australian Broadcasting Corp. When Australia joined the Coalition that took part in the invasion of Iraq, Nelson said that their goal was to fight terrorism and destroy weapons of mass destruction. If this happened in the U.S., it would the same as Secretary of Defense Robert M. Gates announcing that we had gone into Iraq for the wrong reasons.
