Bat Technology May Eliminate Scanners at Airports
A new technology that emits 3mm microwaves may soon eliminate the need for metal detectors at airports. The invention, dubbed Tadar, after the Brazilian Tadarida bat, can create a thermal representation of the scanned item or person. The clothing disappears and anything; change, bombs, guns, toothpaste – you name it – will show up on the scan. Different materials are represented by different colors in the scan. Apparently, the technology is able to scan things from up to 50 meters away.
