Gone are the blades of conventional electric fans - instead his 'Dyson Air Multiplier' design uses technology to amplify air 15 times.
Now for the science bit. It works by accelerating air through an annular aperture set within the loop amplifier. This in turn creates a jet of air which passes over an airfoil-shaped ramp that channels its direction… apparently.
Makers claim this means the £200 fans can expel 405 litres of cool air every second.
Then again for that price it should… alternatively you could just pay for someone to fan you with a giant palm leaf. Speaking of the new device James Dyson said: "I’ve always been disappointed by fans. Their spinning blades chop up the airflow, causing annoying buffeting.
"They're hard to clean. And children always want to poke their fingers through the grille. So we've developed a new type of fan that doesn’t use blades."
