If my vacuum can remove even one spec of dirt that yours misses, then mine is better than yours - even if there's no proof that mine would have picked up as much dirt as yours...

DIB: Sir James has made a career, at least up to now, out of reinventing existing technology, not enhancing it, and charging a huge premium for it. If you proclaim this as technologically innovative you have as much comical chutzpah as Sir James by declaring Air Multiplier fans as bladeless and charging $300. Such overstated claims are self-serving because they are untrue. If the self-server impugns others for disclosing the untruth, then he/she/it is the perpetrator of a lie [albeit hiding under the disguise of righteousness]. That is, indeed, no laughing matter. Except perhaps to the evil one. Carmine D. I think that by blade-less they mean that it's not at the fan opening as is the most case with most fans. As a student of physics, surely you enjoy seeing demonstrations of fluid mechanics principles. This is the kind of silly thing that can spark interest in science by children who wonder where the fan blades are. While it's not practical enough to be sold at a vacuum store, once can appreciate invention for the sake of invention. I certainly agree with you that $300 is a ridiculous price for a fan. However, put the application in a military or medical setting, and perhaps there's something there. The market will decide if there's an application for this product.
The smart tyrant writes his own story to ensure that it is favorable. The lazy will repeat lines from the book without fact checking.

Hello Severus:
Agree. In fact Roomba did this with its robotics. For 10 years it made robotic bomb detectors and detonators for the military before applying the same principles to household robotic vacuums. When it did, Roomba sold over 500,000 robotic vacuums in just 6 months of launch in October 2002. Wonder what happened to the all the buzz about the dyson robotic that was floated here by the dyson "insiders" in the know. M00seUK had it right in 2004 when he said it was probably too late for dyson to enter this market. Roomba had the lock on it from the get go. In business it's not just about the product and price. It's about market timing. Dyson was too late. Carmine D.

Ah yes, the Venturi effect.
 The pressure at "1" is higher than at "2" because the fluid speed at "1" is lower than at "2".  A flow of air through a venturi meter, showing the columns connected in a U-shape (a manometer) and partially filled with water. The meter is "read" as a differential pressure head in cm or inches of water. Carmine D.

Carmine D. Hi Carmine, Is this the way a vacuum's sprayer attachment operates? Venson
