I couldn't find any information on the expected performance of the device, including the absolute and relative quantities of CO2 removed from the exhaust stream in various climates (even if they're resistant to high exhaust temperatures, I'd expect a good freeze to kill off any algae). How much of an impact is this product expected to have, and what are its limitations? What assumptions are made on mileage driven to give it a two-month lifespan?
