This is science at its best: Decades ago, the only practical use for sawdust was to soak up vomit, but thanks to scientists at a Belgian university who developed a new chemical process, that same sawdust could soon be used to create gasoline and other products normally derived from petroleum.

Five years ago we first heard about a Caterpillar diesel engine located at the University of Wisconsin-Madison, that had been modified to run on an unlikely-sounding mixture of diesel and gasoline. Not only did the one-cylinder engine work, but it was more efficient than pure-diesel or pure-gas engines at converting the chemical energy of fuel into motion. Sitting in a basement lab, however, isn't the same as experiencing use in the real world. That's why students at UW-Madison, led by Prof. Rolf Reitz, have now put another diesel/gas engine into a 2009 Saturn. Read More
Contamination of soil from petroleum spills is an ongoing problem that threatens to adversely affect the environment and the health of the people in it, so rapid testing of sites is a pressing issue. However, with laboratory samples and results requiring at least a number of days turn around, particularly in remote locations, rapid analysis is not usually possible. RemScan is a self-contained, hand-held hydrocarbon contamination testing device designed to address this problem. Recently released on the US market, the device is capable of testing many hundred samples a day, providing data on the spot, within seconds, and completely without the need of a laboratory. Read More
Despite efforts to limit their use through implementation of charges or bans, billions of plastic bags continue to clog landfills, waterways and the world's oceans every year. Already a potential source for carbon fiber and carbon nanotubes, researchers have provided another reason not to throw the ubiquitous bags away by converting them into a range of petroleum products.

Keeping a jerry can of gasoline in your car may help if you run out of fuel, but it's also highly dangerous and is therefore illegal in most places. According to the Makers of Magic Tank Emergency Fuel, their product is the safe – and legal – alternative to packing a jug of gas. Read More

Air Fuel Synthesis, Ltd. (AFS), a small company in the northern English county of Durham, has recently made headlines for a chemical process that claims to synthesize gasoline from air and water. In essence, AFS is using energy to unburn fuel so that it can be burned as fuel again – a great deal of energy. Sixty kWh of electric energy are used up to store 9 kWh of that energy in a liter of gasoline. When you take into consideration that gasoline vehicles are about 15 percent efficient, a car fueled with synthetic gasoline would use roughly 35 times more energy on a given trip than would an electric vehicle. Not, it would seem, a prescription for a commercially valuable green product. Read More
If you live in the country or take long road trips, having the fuel light start flashing when you’re miles from anywhere can be a white-knuckle event. It’s tempting to carry a can of extra fuel in the boot for such emergencies, but gasoline is extremely flammable and vents off dangerous gases if it gets warm, so it’s not exactly a safe option. Extra Fuel is an alternative to conventional gasoline that will run any petrol engine, yet is safe to take along. Read More
For most of us, it’s simply one of life’s little annoyances ... those last few drops of fuel that dribble out of the nozzle at the gas station. For the guys at Canada’s Dram Innovations, however, that run-on is a serious problem – and one that they’re addressing, with their Fuel Nozzle Drip Retainer. Read More

With both gasoline and diesel engines having their own particular advantages and disadvantages, automotive component manufacturer Delphi is looking for a best-of-both-worlds solution with a gasoline-powered engine that uses diesel engine-like technology for increased fuel efficiency. According to MIT’s Technology Review, such an engine has the potential to increase the fuel economy of gasoline-powered cars by 50 percent and give hybrid vehicles a run for their money in the fuel economy stakes.

The 2013 Cadillac XTS, which will hit dealerships in a few weeks, is a hotbed of new technology and features for GM. The car is the launch vessel for everything from the CUE infotainment system to vibrating alert seats. This week, Cadillac has detailed a smaller but perhaps equally useful feature. Read More
