dyson fan multiplies air, costs

Unless the blades of your electric fan are quite dirty ' mine are, need to clean them ' I don't think you'll feel that the air coming from the fan is 'choppy'. You'll still feel that steady stream of air right? Dyson disagrees, so it invented a bladeless fan that uses technology found in turbochargers and jet engines to amplify the air that it sucks in. The result is a solid cylinder of breeze in your face. Or wherever the fan is aimed at.A motor at the bottom of the fan sucks in a tiny bit of air, which is then sent to the inside of the circle up top.
