I’ve never seen a trailer like this – perhaps it wasn’t road safe or something, but it would be wonderful to (re)make – via LoL.

It looks dangerous and is, reportedly, incredibly expensive, but there is no denying the near-maximal awesome factor of the Jetlev Flyer. Power comes from a four-stroke engine in a small “boat” which drags in the water behind/below the flying harness, and to which it is tethered by a big yellow hose that supplies high-pressure water and prevents the operator from exceeding a safe altitude. [Thanks, Alan Dove!]

Maybe I’m venturing into tinfoil hat country, here, but I’m pretty sure I once experienced a flyover by a stealth helicopter. I was camping at a lake in central Texas, during the Fall of 2003. Everyone else had gone to bed, but I was unable to sleep and was sitting up by the remains of the campfire, around 2 AM, just listening to the sounds of the forest, when I very clearly heard a distinctly unnatural sound pass across the dark sky overhead. It was very quiet, and very slow (rhythmically), but unmistakably a helicopter: whup whup whup whup whup. It was a clear night, and the speed at which the sound passed overhead meant it had to be flying at low altitude. There were no lights, just the sound, and I had a very eerie mental image of the glowing silhouette of my body, sitting beside the bright star of the cooling campfire, on a thermal imager cruising somewhere through the blackness above.
This wicked-looking rotor design is called “blue edge.” You can read more about it, and hear a comparison to normal rotor noise, over at Wired’s Autopia.

Jason Rollette’s remotely-operated submarine packs four 500gph and two 1,250gph bilge pumps, with the bigger ones used for propulsion. Check out his incredibly detailed tutorial for instructions on how to build your own. [via Hack a Day]

Our very own Rachel Hobseon @ CRAFT spotted these. She writes:
This project combines two of my favorite things: crayons and rockets. It may have taken John Coker 12 years to complete this project (hey, who among us hasn’t had a case of lingering works-in-progress?) but the result was more than worth it. He’s even included a step-by-step of how he made the rockets. The detail in matching the Crayola design is pretty impressive. I just want to know if he could find a way to add in that awesome Crayola smell.

Don’t let the elevator music distract you, this system can squirt water at 4 bars, or about 60 psi, as compared to a typical fire hose which packs a working pressure of 100 psi or more.
[The] system consists of a number of rotating water jet guns installed on the shipside which provide a continuous high pressure water curtain all around the ship side. The system once installed can be remotely operated from a safe location without any possibility of harm or injury to crew. The system does not require any additional installation which are costly, time consuming and might require various class or administration approvals. Furthermore it provides a visible deterrent to the pirates who will possibly divert to easier targets.

Nine enterprising seniors in Yale’s Mechanical Engineering program built this rad spokeless bicycle for their mechanical design class. Thinking about the off-axis forces that those bearings will have to endure makes my head hurt (and that has to be one strong frame!), however the effect is totally worth it. [via neatorama]

When I was at UT Austin, a school which is famously car-unfriendly, it was rumored that one of the elder patriarchs of the College of Natural Sciences–a man who had multiple doctoral degrees and had been given countless awards for his work both as a scientific researcher and an educational administrator–had once quipped that the honor that was most valuable to him, on a daily basis, was the “O” parking permit that let him leave his car literally in the shadow of UT’s iconic tower.
Well, in terms of available parking, UC Berkeley makes UT Austin look like an airport remote lot in Iowa on a Wednesday in the dead of winter. And according to this official page there are presently seven living Nobel laureates on the faculty there, so I’m guessing there must be at least seven of the prestigious NL parking spaces. Supposedly, regular mortals have to shell out $50 for presumptuous malparkage among the elite.

A commenter on my recent dazzle camouflage post alerted us to the fascinating story of the HNLMS Abraham Crijnssen which, in 1942, escaped destruction by the Japanese fleet because the crew moored her among other small islands and covered her in a thick layer of tree branches, thereby disguising her as a small island.
