It DOES work. I have strained soup many, MANY times, to get a TOTALLY grit-free beverage. AND I have used a vacuum-cleaner, which emits TOTALLY grit-free air. (Note that my tiny "Shark" hand-held vacuum cleaner has enough suction to pick up a bowling ball!) Not to mention that there are other solutions to the debris problem, somewhat more sophisticated than a strainer: like for instance Dyson's centrifugal force vacuum-cleaner which uses neither a bag nor a strainer. (See for instance <http://www.wipo.int/pct/en/inventions/bagless_vacuum_cleaner/>, if you haven't already seen the numerous commercials about it on TV!) Besides, I did not find anyone else claiming what you claim. Popular Science says no such thing in their article in the September 2004 issue which is totally devoted to cars, even though they have a photo of the Chaparral prominently displayed; and neither do any of the racing magazines I have come across when discussing the Chaparral. Indeed it's likely that the open tires on race cars would throw up far more debris than any fan. (You seem to have a problem for every solution, Austin. It might do you some good to take a tip from Management *Guru* Tom Peters, and treat every challenge like an opportunity, rather than treating every opportunity like a challenge ... ;-)! Cheers! +++++ PS: Uh ... I notice that you give no REASON above for your saying that it won't work. Is there a reason why you hesitate to give a reason?
