This weekend I was carving pumpkins with my girlfriend. Pumpkin carving, a soothing time to bond, relax, and justify having power tools. Rather than hacking away at a pumpkin with a dinner blade, my trusty jigsaw and dremel did most of the cuts and an exacto knife detailed. It was much less effort and the pumpkins came out great.
Being me, I wasn’t settled with a mildly dangerous tea candle. I upgraded the wick by adding part of a regular candle. This made the pumpkin burn with a much more ominous glow (Harzard +1).
It was good, but not great. I went down to the shop and bore a hole into the back of the pumpkin. Add one spray can and that brought the pumpkin from seasonal fire hazard to double fisted spray can/fire extiguisher dangerous (Harzard +3 Safety +2).
In hind sight I should have bore the hole larger. Why? Well the fuel I’m spraying there tended to puddle up in the opening and set the pumpkin on fire, thankfully the pumpkin was fresh and still moist.
No it’s not a stargate, believe it or not it’s a bladeless fan. This fan blows a stream out of the blue ring. The blue ring has a special airfoil shape that can magnify the airflow up to 15x. Since it involves no blades this stream is uninterrupted. This fan seems pretty cool (if $300 means nothing to you,) if you ask me I’ll stick to my propellor style fan. Mine comes with soothing fan noises and doubles as a sound effect generator.
It certainly has the wow factor, but hackaday.com pointed out it probably has blades in the bottom to push air into the ring. Perhaps not the same traditional style but blades still. This design is very novel, so as far as the user is concerned it’s bladeless. It’s like buying a Roomba and realizing it needs to be emptied every once and a while.
Dyson also developed the Airblade hand dryer (the funny looking one you place your hand into and pull out slowly.) Plenty of videos on their site.
