Experimental diesel/gas engine could give 2009 Saturn a big boost in fuel efficiency

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

Handheld device detects and analyzes soil contamination within seconds

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.

Magic Tank keeps your car going when the gas runs out

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 + water = gasoline? Not quite...

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

Extra Fuel is a safe petrol reserve to keep you motoring

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

Fuel Nozzle Drip Retainer keeps gasoline off the ground

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
