Those who’ve tried The Blade say it works – though, so far, we’ve not met any of them. The proported fuel-conserving, emissions cleansing attachment for autos hit the market late last year amid kudos and celebrity endorsements (Sheryl Crow, Laura Dern and Ben Harper say it’s da bomb).
The simple tail-pipe attachment/filter is said to cut auto emissions by 57 percent, and greenhouse gases by six to 34 percent, depending on the model of your car. That makes the $200 price tag reasonable enough for the carbon-conscious.
But the fact that it can increase fuel economy up to five miles per gallon makes it attractive to just about every Joe and Jane Sixpack in the country.
