Can someone explain how the Dyson works? The website is pretty vague, describing an "airfoil shaped ramp". Does the round part spin? If so, how do the oblong ones work?
Actually I have heard about Dyson bladeless fan in 2009, and I really love the design,but it’s too expensive! You know what, this concept is for cooling extrusions in a factory and not his “invention”. But he named it the Dyson fan anyway. The name and the price tag gave me the impression of ego and greed, which may not be true at all. He believed that it would sell even if way overpriced. He is right. Some people are buying it. But I think he would be much smarter and reasonable if he priced it under $100, and he would be benefiting more people and making much more money that way, and people would think much nicer of him. and everyone will be happy. After all, an invention should be to benefit as many people as possible, and not just a few immature adults who like toys such as myself. i bought a mini bladeless air multiplier on SpeMall.com for only $40, it's cute and i think it's worth for the money, maybe you guys should have a look, here's a link for your refer:http://www.spemall.com/Bladeless-Fan_c.html
