Computers get hot. Heat is bad for computers. To whisk it away, we use a combination of heatsinks and fans to snatch heat away from the internals and blast it out of the computer's case. But Sandia has a concept that combines the two in a way that, they claim, increases heat-removing efficiency by up to 30 times.
Even though the ring-shaped Air Multiplier fan isn't particular powerful at $300, it's still, well, a bladeless ring! And while the answer to what comes next can only truly be known in the jetstreams of genius cycloning around in Dyson's head, cartoonist Tobias Lunchbreath has taken a stab at what ring-shaped future luxuries we may have the pleasure to purchase in the future.
Ever since Schuyler Skaats Wheeler introduced the first axial-bladed electric desk fan in 1882, fan technology has remained remarkably conservative. But that classic bladed design wasn't good enough for the innovative people at Dyson. With their new desk fan, Dyson has thrown out over a hundred years of axial desk fan technology to create the first fan that provides a continuous stream of smooth air.
The retro-futuristic design of this skateboard was inspired by the look of rocket ships in old cartoons. Ryan Bavetta used a jigsaw to cut out the sleek deck and then mounted a propeller and 3.7-horsepower engine from a model airplane on the back to power it. A handheld remote controls the engine throttle, which can move the board 25 mph or more wherever he wants to go.
