Dyson invents bladeless green fan

British inventor Sir James Dyson has launched a bladeless environmentally-friendly fan which he hopes will replace air conditioning.

The designer, famous for the invention of the bagless vacuum cleaner, said his fan stops the “turbulent buffeting” of desk fans, replacing it with a constant air flow “like a breeze”.

The fan will be priced from £199, and is claimed to use a 50th of the electricity of an air conditioning unit.

Sir Dyson said: “If only we could open a window and use a fan then we would be saving a huge amount of electricity, and stopping the emission of HFCs and also having a much healthier environment.

“There’s just as much air flow, and just as much speed, but it’s comfortable to be in front of it.

The fan, which spent three years in development and a year in production, also oscillates and comes with a dimmer switch to adjust its power.
