High school students create Road Iron, the pothole detector
Some high school students near Boston have figured out what has eluded transit agencies for hundreds of years: they have come up with the Road Iron, a device that detects and repairs potholes before they have a chance to form. The device looks for cavities below the pavement and then drills in and fills them, fixing the problems before they occur. The current method of "fill the hole after someone kills their suspension" could very well be replaced by something that was discovered in a classroom.
