The unit itself is a power miser, operating as long as two years on two AA batteries. It also uses novel display technology that makes the data visible even after the power is turned off. It uses ZigBee, employing a 100 mW power amplifier that covers most homes without a repeater.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
