Pollution

A demonstration of how the phosphorus-laden particles can be removed from water using a ma...

Phosphorus is a mineral that's widely used in fertilizer, which itself has an unfortunate tendency to leach out of farmers' fields and into our waterways. Now, researchers from Germany's Fraunhofer Institute for Silicate Research have devised a method of retrieving some of that phosphorus from the water – thus both reducing pollution, and providing a source of reclaimed phosphorus.  Read More

The Audi traffic light system uses icon prompts

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.  Read More

The unit will fit inside a shipping container, and could be towed around the port on a bar...

Shipping ports are major sources of air and water pollution, due in part to anchored or docked ships using diesel generators to keep their onboard systems powered up. A year from now, however, the Port of Honolulu will be trying out a mobile hydrogen fuel cell unit, as a more eco-friendly and fuel-saving alternative.  Read More

Regular catalytic converters like this one may be on their way to obsolescence (Image: Shu...

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

The Wendy Schmidt Ocean Health XPrize aims at combating ocean acidification (Image: NOAA)

Since 1995, XPrize has been promoting science and technology by setting “Grand Challenges” with cash incentive prizes. On Monday, the organization announced the launch of three new competitions by 2020 as part of its XPrize Ocean Initiative, which is aimed at improving the health and understanding of the world’s oceans.  Read More

The Ocean Cleanup Project hopes to utilize the oceans' gyres as a means to collect plastic...

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.  Read More

The new system being tested on the A6 highway, near Madrid

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

Designed by Chilean architect Gonzalo Mardones Viviani to serve as family home to compatriot and former tennis star Marcelo Rios, House RP features a futuristic-looking design that would look right at home in George Lucas sci-fi movie THX 1138.  Read More

The range of Yikebikes now ranges from US$2000 to US$4000

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

Researchers at University of Texas at Arlington have developed a novel means of creating m...

Most previous methods of producing methanol from carbon dioxide have involved lots of electricity, high pressures and high temperatures, and used toxic chemicals or rare earth elements like cadmium or tellurium. A team of researchers at the University of Texas at Arlington (UTA) has developed a new method they claim is safer, less expensive, and simpler than current approaches and can be scaled up to an industrial scale to allow some of the CO2 emitted from electrical power plants to be captured and converted into a useful fuel.  Read More
