The Dyson Air Multiplier might be the next generation in fan technology. Gone are the fan blades you’ve seen on every other fan every. It’s replaced bye a hollow ring. Basically air is sucked into the base of the fan and then forced around the inside of the ring and shot out of one side of the ring. The ramp-like nature of the ring causes it to induce air to move from behind the ring through the hollow middle of the ring resulting in a fan-like experience. The technology, while cool, is quite loud- like small vacuum cleaner (something Dyson knows all about). This new type of fan is for sale now for around $300 which i about $290 more than a comparable blade fan.
