Startup: Coaxing The Air Into Submission

No, it’s not My First Stargate™ for Kids, but that would be cool. This is a bladeless tabletop fan, from Dyson – the same guys that gave us the bagless vacuum cleaner and the self-righteous advertising campaign. It’s not truly bladeless, the fan is in the base, sucking air into the unit where it gets blown back out from the inner rim of the hoop. The magical part is when that air moves over the inner surface of the hoop, which is shaped similar to a airplane’s wing (or aerofoil, if you want to get technical). Similar to how the wings create lift on an airplane, a combination of Bernoulli Principle and the Coandă Effect cause a lower pressure region to form in the middle of the ring, sucking air in from behind and blowing it out the front. Apparently, these things move 15 times more air through the hoop than goes through those intake vents on the bottom. Sounds amazing – I would love to hear from anyone who’s got one or at least seen on in action, because it sounds a bit too good to be true. For all I know, standing in front of one of these things is like getting sneezed on by a gerbil. For now, I have to make do with this silly video. I’m sure it was fun to make, but at a starting price of $300 a pop, it was also crazy expensive.

Almost there. Still needs some tweaks.

It’s often easy to forget that the word “technology” doesn’t necessarily mean lights and wires. It’s widely believed that the wheel is the greatest invention ever (unless you ask John Waters, who will claim the answer is “ultrasuede”.) After that, we saw millennia of technological wonders without […]

User Input: A Brave Old Era

When Apple ran their original Mac ad during the SuperBowl, it made the news the next day. Partly because it was such an attention-getting ad, but also partly because they were introducing a new kind of PC. There’s a new PC unveiled twice a week nowadays, so nobody cares anymore; but back in the 80’s it was a big deal.
