The Dyson bladeless fan generates airflow by drawing in air and spinning it at high speed. The turbine is made of a series of loops, each one with its own set of blades. As the air enters the machine, it's drawn into the first loop and then out to either side through guidance vanes. It emerges from these loops faster than it entered them, causing it to continue spinning even after it leaves the machine completely. The turbine is powered by a gear train that accelerates the air past the vanes, and then through a series of blades at the very end. This technology has been available for several years now, but it remains relatively expensive. However, Dyson is planning to make it more affordable in the future by reducing its energy consumption.
