The Dyson Air Multiplier is a welcome re-evaluation of the typical household fan. Instead of using blades and rotors like typical fans to speed up airflow, Dyson used its know how in airflow technologies, to devise a device that takes in a small quantity of air, accelerate this air, then propel it outward along the rings. The air surrounding the fan is then accelerated up to 15x by induction. [A more detailed description and accompanied video may be found in the source at the end of this post.]I enjoy this design, for it truly is "thinking out of the box." Dyson took an everyday object, an object that wasn't screaming to be improved upon or replaced, and completely re-engineered it anyway. Given my engineering background, I am well aware of the many pitfalls of re-engineering. The process of re-engineer typically results in wasted time, wasted energy, and improvement on a product that may not need improvement. But this device isn't such a design. Dyson completed changed the process, and in doing so vastly improved the overall product. No longer will dust buildup and dangerous blades be an issue. A true laminar flow of air will result in much more efficient cooling, as opposed to the very turbulent design we are used to. An the aesthetics of the device are wonderful. The huge loop of whites and grays scream a modern openness.
The only pitfall to this wonderful creation... the price. At $300.00 all practicality is thrown out the window. For $40.00 one could buy two fans that match the output of this one. And granted yes, it is a wonderful design combined with great technology, the final cost may leave it nothing more than a novelty.
