Wouldn't it be great if you could buy a device on the Internet for, I don't know, $200, bolt it onto your car and enjoy an instant reduction in emissions and an increase in fuel economy?
Claims like that are as old as the hills. We've all heard about the 100-miles-per-gallon carburetor that "they" don't want you to have, and the scientist whose invention was mysteriously suppressed just as he was about to bring incredibly cheap people's power to the world (think Nikola Tesla).
The Blade: Looks good, doesn't it?
It's inevitable that when fuel prices zoomed up, these devices would see a revival. (Yes, I know gas has come down, but is anyone really happy with $3 a gallon?)
Free lunches are hard to come by, however. Popular Mechanics tested a bunch of "fuel savers" back in 2005 and concluded that absolutely none of them worked. One even started a fire. These devices use miracle magnets, vortex generators, ionizers and water injection. But the only thing they reduced, PM said, was the cash in your wallet.
And this brings us to the latest device, The Blade, which bolts on to the exhaust pipe. It's kind of cool looking in a retro way. Remember those chrome exhaust tips people put on their cars to create a fake hot rod? I've only seen pictures on the website, and I have no idea if the Brazil-sourced Blade actually works. But, given the history, I think caution might be in order.
Don't worry, though, because actress Laura Dern says it works. "Having a Blade on my hybrid car allows me to continue driving with the satisfaction that I am lowering my carbon footprint and burning less fuel," she says.
The Blade is definitely more credible than most. The company paid for independent testing by the respected Automotive Testing and Development Services (ATDS) in Canada. On a 2004 Honda Civic, the Blade allegedly achieved a 57 percent reduction in hydrocarbons, 14 percent in carbon monoxide, 34 percent in nitrogen oxides and six percent in carbon dioxide (the main global warming gas). And on the highway, the numbers show it achieving a five percent fuel economy improvement.
ATDS Vice President Lin Farmer, who conducted the tests, said the Blade "seemed to be doing something on the positive side." He pointed out, however, that the 2004 Civic is a very low-emission car (the numbers for emissions of hydrocarbons, for instance, ranged from 0.0010 without the Blade, to 0.0004 with it).
"It's possible that some of the large improvements in gases are due to test-to-test variability and the fact that we were working with such small numbers," Farmer said. He added, however, that the Blade "performed better than other devices we tested." And the fuel economy numbers impressed him.
William J. O'Brien founded parent company Sabertec in 2005, after he came across the Blade on a visit to Brazil in his role as a venture capitalist. He's a great talker, and I can't pretend to understand everything he said. Luckily, there's a You Tube video that lets you judge for yourself. Here's some of what he said to me when I asked him how a device bolted on to the tailpipe can increase fuel economy. It's unfortunately somewhat paraphrased, because he talks fast:
