BLADE is a retrofit device that attaches to the tailpipe of any gasoline, propane or CNG burning car, suv,van or light duty truck to: Capture toxic Particulate Material (Smog) Reduce CO2 by up to 12% Increase fuel efficiency up to 12% CO2 ReductionLaboratory test results show decreases of carbon dioxide (CO2) up to 12%. CO2 is a potent greenhouse gas and is the primary cause of man-made global warming. Particulate Material (PM) FiltrationParticulate Material (soot) is an air pollutant known to cause grave environmental and human health consequences. Environmental consequences of PM include: air pollution, water pollution, deforestation, crop degradation, acid rain, acidification of waterways and smog. Health consequences of PM include: cancer, cardiovascular and respiratory disease, fibrosis, asthma, reduced pulmonary function and increased mortality. Laboratory testing using the EPA 511 Protocol shows gas mileage increases of as much as 12%. Consumer experiences conducted on a wide variety of cars, light duty trucks and SUV’s in the U.S., Europe, and Latin America have resulted in gas mileage increase up to 34% on 4-cylinder cars, Ford Focuses, etc.•21% on light duty trucks and SUV’s, e.g. GMC 2500s, Chevy Avalanches, Range Rovers, etc. 16% on dual exhaust 8-cylinder sedans, e.g. Lincoln Town Cars, Crown Victorias, etc. 24% on 10 cylinder Box-style trucks, e.g. U-Haul moving trucks.
