Roads laced with titanium dioxide could help us breathe easier
Filed under: Etc.
Researchers at the Eindhoven University of Technology (EUT) may be on the brink of discovering a breakthrough that will lead to reduced pollution and cleaner air for all. According to the EUT, a roadway made of concrete blended with titanium dioxide can effectively remove up to 45 percent of the nitrogen oxides that it comes in contact with. The titanium dioxide, a photocatalytic material, captures airborne nitrogen oxides and, with the aid of the sun, converts it to nitrates that are harmlessly washed away by the rain.
The EUT conducted real-world studies on a 1,000-square-meter section of repaved road in the Netherlands. Such testing showed that the laced pavement could reduce nitrogen oxides by 25 to 45 percent more than traditional concrete. As Jos Brouwers, professor of building materials at the EUT remarked, “The air-purifying properties of the new paving stones had already been shown in the laboratory, but these results now show that they also work outdoors.”
Additional testing is still underway and although the pavement laced with titanium dioxide does cost some 50 percent more than regular cement, overall road-building costs only increase by a marginal ten percent. Costs aside, the advantages of the titanium dioxide are readily apparent, but the implementation of such a product requires repaving our roadways, a time consuming endeavor for sure.

Driving the Ford Focus RS, the Feistiest Ford
There are plenty of things in Europe that we Americans unfortunately donât get to enjoy here on home soil: Monstrous medieval castles. No speed limits. Beer stronger than Coke Zero. Of course, some pretty damn cool rides, too.
Like many of my cohorts, I have drooled over Fordâs Focus RS (and RS500) from afar. And now, thanks to Continental Tire, Iâm happy to report that Iâve driven the snot out of a Performance Blue example during a recent stay at the brandâs Contridrom test facilities near Hanover, Germany.
To experience one of the worldâs hottest hatches first hand — on a track, no less — was a completely unexpected treat. I travelled to Deutschland for a test of the latest German tires, not cars. But when the Focus rolled up to the tightly twisted wet handling course (Imagine a regular circuit with small sprinklers constantly dousing the pavement, and youâll get an idea of the Slip ân Slide-like environment), I had to see if it was worth all the international hype. Strapped into the snug Recaro bucket, I was giddier than a thirteen year old during The Twilight Saga: Eclipse premiere.

Hyundai i20 Receives Interior Upgrades and Cleaner Engines
The Hyundai i20 is getting blue on the inside and greener under the bonnet. Minor changes to the aerodynamics and engine have resulted in a boost in fuel efficiency for all engines, while the interior is now more stylish and better equipped.
The best-selling 1.2-litre petrol engine, already one of the most efficient in the class, drops its emissions by 5g/km to 119g/km. This results in a tax disc costing just £30 and company car tax benefit-in-kind rates of just 10%. Buyers wanting the extra power of the 1.4-litre version will see even greater savings, with the Style models dropping by 13g/km to just 129g/km. This results in a drop of two Vehicle Excise Duty bands and a 4.3mpg improvement.
The two diesel engines also see significant savings, with the 75PS model dropping by 6g/km to just 110g/km. The 90PS version gains a six-speed gearbox which helps it achieve a 7.2% improvement in fuel economy.
These improvements have been made possible by adding a small spoiler to the underneath of the car to improve airflow around the wheels, fitting an Eco Drive indicator in the instrument panel to suggest the best point to change gear, using low friction engine oil and an alternator management system.
Inside, there are two blue additions. Firstly, the dashboard and instrument illumination is now blue rather than red, bringing the i20 into line with larger Hyundai models. Secondly, Bluetooth phone connectivity with voice recognition is now added as standard on all models except the entry-level Classic.
