'Solar highways' transform our crumbling infrastructure into something useful

Okay, we know YOU ride your bike everywhere. But the country’s 4 million miles of roads, and 50,000 miles of interstate highway, probably aren’t going anywhere any time soon.

In the future, cleaning robots will sniff out air pollution

Researchers at the Public Laboratory for Open Technology and Science have kitted out a Roomba -- you know, one of those robotic vacuum cleaners that cats ride around on and act out Citizen Kane -- to evaluate air quality. Lights on the Roomba indicate the presence of evaporated alcohol, and a long-exposure photo, above, can show which parts of a room are clean and which are fumey. Blue lights in the above photo mean that the robot detected polluted air.
