Halt! Hold it right there, Citizen Contraptionist! You’ve gone too bloody far this time! Necessity may be the mother lode of invention, but precisely what necessitated the removal of the circulating blades from a circulating fan? Time was, if stuck your head into a proper fan, you came out with a bloodied head, as well you should have! The loppin’ of the noggin' was collateral damage in the war on stagnant air and the karate chopping of the blades was the munition that spelled triumph, which is to say, welcome, cooling relief. To paraphrase a credo from the exterminator’s trade, if you build a better mousetrap, the world will beat a vacuumed pathway to your door, but the world will surely stride past your entryway rather than embrace this "air multiplying" imposter! As to your previous invention, the Dual Cyclone® bagless vacuum, I’ll admit to being more receptive and intrigued by the Houdini-like disappearance of the dirt. You proved yourself worthy once, Sir James Dyson, CBE (Commander of the Most Excellent Order of the British Empire) and pride of Norfolk. Methinks you best go back to the drawerering board or find yourself forever in the shadows of the quintessential electronics creationist David Oreck XL!
