Water-testing pills draw on breath-freshening tech

Wondering if it's safe to drink the water from your remote village's well? Typically, the only way of finding out involves sending a sample of that water off to a lab, or using testing agents that must be shipped in and kept on dry ice. Now, however, scientists from Canada's McMaster University have developed simple pills that can do the job – and they were inspired by breath-freshening strips. Read More

Audi Online traffic light system helps drivers hit the green lights

One of life's small but satisfying pleasures is hitting the sweet spot while driving across town and catching all the green lights. At the moment, having that happen is a matter of luck, but Audi is developing a system that will make never getting caught by a red light an everyday thing as a way of speeding up traffic while improving fuel efficiency and cutting emissions.

New catalytic converter could make cars cleaner, more fuel efficient and less expensive

By helping to minimize the hydrocarbons and other pollutants that are emitted in a car's exhaust, catalytic converters serve an important purpose. Because they contain precious metals such as platinum, however, they can also be expensive. Now, a British scientist has developed a new type of converter that should be cheaper, longer-lasting and more effective, plus it should boost the vehicle's fuel efficiency. Read More

Cleanup Array concept aims to rid the oceans of plastic waste

Boyan Slat, an aerospace engineering student at the Delft University of Technology, is working to combine environmentalism, technology, and his creative outlook to rid our oceans of plastic debris. His Ocean Cleanup Project aims to utilize the oceans’ natural gyres (five circular currents in the oceans around the world – two in the Atlantic, two in the Pacific, and one in the Indian) to collect plastic waste.

Camera system "sees" toxic emissions from individual vehicles in real time

According to scientists at Spain's Universidad Carlos III de Madrid (UC3M), approximately five percent of vehicles on the road are responsible for about 90 percent of toxic vehicle emissions. Short of pulling each and every car over to analyze its tailpipe output, though, how does one go about identifying the offenders? Well, the UC3M researchers have helped design a system that images the emissions of individual vehicles in real time, on highways up to three lanes wide. Read More

Lighter Yikebike EV models join growing Transport Appliance marketplace

With big changes likely in the global transport infrastructure, the race is on to create the missing link – the smallest, lightest man-packable form of motorized transport yet known. Honda, Toyota, Volkswagen, BMW and Nissan have all shown vehicles in this area, but none have yet hit the market. The best-of-breed is currently the Yikebike and it announced today that it has further extended its lead, lightening its US$4,000 Carbon model from 11.5 kg to 11.2 kg and extending its range to 15 km (9.3 miles). There's also now a choice of Yikebikes with two cheaper versions at 12.7 kg ($3,000) and 14 kg ($2000). Read More
