Tech Tuesday 1/29/19 – Cool Sounds Edition
[TT1] A few weeks back, I talked about using small drones to inspect aircraft turbines. Now we have a small robot to inspect the skin of an aircraft. Overall, I support using drones and robots for aircraft inspections, as long as the software that is evaluating the sensor feed is more capable than a person at spotting an issue. I’ve done these kinds of inspections, on hovercraft and airliners, and it can be mind numbing. I’d rather a robot spot and flag dozens of issues for humans to evaluate, than having a person get tired and bored doing an inspection and miss things.
[TT2] Apparently, the magnetic poles won’t stop and ask for directions, either.
[TT4] Researchers have figured out what causes rogue waves to form. The magic number is 120. I’ve never seen one of these monsters, but they are no joke. They will break a ship in half.
[TT6] I get how the laser creates the sound, but wouldn’t anyone along the beam path also hear the message, not just the intended recipient?
[TT7] Speaking of lasers, we can use them to flash transform carbon nano-tubes and fibers into diamond. Suck it, DeBeers.
[TT8] Last time, it was Bell getting into the VTOL market, now Boeing. Their entry is not what I’d call attractive. Seems perfectly safe and functional, but about as exciting as a Corolla.
[TT9] A ready made Thermo Acoustic Cooling Plant. What is Thermo Acoustic Cooling? It’s an old process that was originally developed by the US DOD back in the day, that starts by taking heat and turning it into mechanical motion. That motion is in the form of sound waves. The sound waves travel around the blue circle, building up acoustic energy. At some point, that energy hits a desired peak (amplitude), and that can be used to create a delta Temperature to provide cooling. The actual physics are rather obscure. The overall point is that this is A) Not Humbug, and B) is done without working fluids that are dangerous to the environment, or any significant energy input (aside from pumps to move the heat around).
[TT10] Yes, finally, I can exercise while reading a book! OK, yes, I’ve done that before, back when my leg was getting rehabbed, but those electro-stimulators are fecking annoying.
[TT11] Bio-solids! Pshaw! Just say what they are, poop bricks. But, they do lock stuff like heavy metals away so they aren’t leaching into the ground.
[TT12] Pulling CO2 out of the air in exchange for H2 & energy. Of course, the end result is all that nasty NaHCO3 we have to deal with. I’m sure we can all volunteer to make some cakes and cookies with it.
