From the ◼ product description:
Fashioned as an athletic wristwatch it uses kinetic energy as a clean power source. Although it does function as a regular watch, it also constantly keeps pulling in air through the intake vents collecting CO2, and expels new clean air via the exhaust vents. A step in the right direction for an individual, the eCO2 has the potential to make a powerful impact if worn collectively.
Now, Bob, and Ryan, this is your chance to get in on the ground floor, open a franchise!
