Students Devise Method of Using Roads as Energy Source

The National Weather Study Project, a competition in Singapore that promotes thinking green, recently pitted teams from 152 schools against one another. The various groups submitted a total of 235 projects. One of the three winning teams, from Anglo-Chinese Junior College (ACJC) in Singapore, developed an idea so intriguing it earned the designers a $10,000 prize and a chance to demonstrate it at an upcoming showcase in Germany.

According to the Straits Times, the group of four students from ACJC developed a system involving water pipes built under roads. Heat gathered and stored by the roads warms the water, providing a greener alternative to gas or electric heating systems, and a significantly cheaper alternative to solar panels.

Specifics of how the system works aren't available yet. If truly effective, the system could actually become a widely accessible green energy source (we've got a lot of streets), since solar panels and other methods typically require exorbitant costs to purchase, install, and maintain.

GPS Leads Truck to Impassable Road for 5 Days

Truck Blocks Road for Five Days Thanks to GPS
If you have a GPS, you've surely noticed that, from time to time, it gives directions that are a little bit... wrong. Maybe it got the name of an exit incorrect, or told you to turn down the wrong way onto a one-way street, or maybe even told you to turn onto a road that didn't exist. You're certainly not alone in these findings, but we hope your wayward directions were less of an inconvenience than those suffered by an unnamed truck driver in the village of Cotswold, England. His GPS directed him down a tiny road that was too small for his rig and, when he tried to back out, he got stuck, completely blocking the road for five days while his company struggled to extract it!

Do you use GPS in your car to get around?



This is an increasing problem in England, with its many small, country lanes that are completely unsuitable for large vehicles. Most GPS devices don't know the difference, and will route cars, trucks, and everything else down these narrow roads, leading to fun times like this.

Oregon Begins Building First "Solar Highway" Project

Just over a year ago, we passed off a far-out proposal that would turn highways into wind farms. Now, however, the state of Oregon is proving that such feats are actually within reach as it breaks ground on the first so-called "solar highway" demonstration project. The project will be installed at the Interstate 5 and Interstate 205 interchange in Tualatin, where it will cover around 8,000 square feet and produce 112,000 kilowatt hours per year. The total cost for the 104-kilowatt solar photovoltaic system is $1.3 million, and believe it or not, it should be completed and operational in December of this year.

Driver Causes Fatal Wreck While Texting On Cellphone

Texting while driving is dangerous.

Here's a somber reminder of why it's important to pay attention to the road while driving.

A California woman was driving along a highway at 66 miles per hour when she crashed in to a line of cars stopped by a construction zone. Why didn't she see the line of cars stopped ahead of her? Because she was too busy sending text messages from her cell phone.

Many states and provinces in North America have banned talking on cell phones without a hands-free device while driving. Some states are going a step further, banning use of a cell phone while driving altogether. But fewer states and municipalities have banned texting while driving. Some are getting wise to this major and dangerous distraction, with Washington State leading the way.

A 2006 University of Utah study found that people driving while talking on a cell phone were as impaired as if they were driving with a 0.08 percent blood-alcohol level. Another 2006 study by Liberty Mutual Insurance Group and SADD (Students Against Destructive Decisions) found that instant and text messaging while driving leads the list as the biggest distraction while driving for teens.

Hertz Vs. Avis (GPS Road Test)



If you ever rent vehicles while traveling, you know that you can tack on an additional $10 a day or so for an optional GPS unit that gives you turn-by-turn directions. Most rental car companies are beginning to feature this option, but the Big Two -- Hertz and Avis -- offer it in almost all of their locations. Not surprisingly, the GPS offerings by Hertz and Avis are different. Which is better? To find out, we test drove the GPS navigators of Hertz and Avis. Check out our findings in the above video.
