Fans without blades?

I remember the days when I was a kid, putting my fingers into a gap while fan is running and got cut. My fingers were bleeding and all the people were freaking out about it. Yes, fan is a big danger when you have children around you. Children’s curiosity often ends up being a negative result of something.

Speaking of which, inventing a fans without blades is something that made parents less worried. Not only the safety issues, but also dirtiness issue has been solved. After not using a fan during the winter season, blades are covered with dust and dirts. People need to take fans apart and clean inside and outside. Normal fans creates winds by chopping of the air, which causes irregular shape of air coming from fans. However, Fans without blades is creating air in slightly different way. It utilizes the air multiplyer.

James Dyson is the person who invented fans without blades. It is very interesting how he got an idea of making no blade fans from restroom hand dryer. As many people have telling me that crazy inventions actually come from something that is very minor. I need to start paying attention to things that are around me and hope that I will get some great ideas at one point!

  1. It looks very cool. But I cannot tell after reading this and going to all three links how it works. The air enters the base and comes out of the ring. My guess that a fan is moving it. In which case it is a bit of a trick and very expensive – about 10 times the conventional equivalent. Dyson is really pulling a con isn’t he?
