A number of sensors have been developed to detect excessive alcohol consumption and prevent impaired drivers from starting their vehicles. The application has primarily been incorporated as a punitive step for repeat offenders. However, when a carmaker proposes a concept, the possibility of OEM use gets a step closer to reality — a step which could prevent or reduce deaths and accidents from drunk driving. Saab's Alcokey concept combines an alcohol sensor with engine immobilizer technology. A key fob with an integrated mouthpiece provides a sample of the alcohol content in the driver's breath to a small semiconductor sensor. An excessive level of alcohol prevents the engine from starting similar to the immobilizer in existing anti-theft systems.

For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
