Commercial Items Identified on my Commute

Image
I see a lot of interesting commercialitems on truck on I-75. When you make the commute many times you start to see the same items over and over again. Sometimes it is huge equipment tires, sometimes heavy equipment of different types. I see these huge blocks of aluminum going North. I think about what the mill must look like and where it is going. And how much aluminum foil a block like this will make. Using the Tesla Full Self-Driving (supervised) allows me to look for these things on the highway. The FSD also helps me through the crazy stop and goes. Easily over 70MPH and then sudden traffic at dead stops, frequently. I see accidents every trip. It is amazing there aren't more. A side note- aluminum foil has a shiny side and a dull side. The reason why is that the foil is folded as it goes through massive rollers. The shiny side is the side that faces the steel roller. The dull side faces itself - aluminum.

VLJs --- 20 years after all the hype

20 years ago the world was abuzz with the VLJ (very light jet) movement. I got to park next to this one the other day in South Carolina. Here is an article from Wired magazine from 14 years ago indicating the demise (or morph) of the hyped VLJ. (Wired article from 2009). The plane in the picture is the Cirrus Vision jet. It probably won the contest in actually (mostly) delivering on the promise of a VLJ. The actual cost of the plane here (about 3 million USD) is way outside what the ridiculously low projected pricing of 20 years ago. But, the plane is cool for sure and is very relateable to the Cirrus piston aircraft. The cruise speed of the vison jet is 345 mph. The Honda jet cruises at 424 mph and the Phenom jet at 466 mph. The speed of the vision jet is incredible compared to my Cessna 172 at 140 mph, but the Vision jet speed is pretty much with the turboprops. (King Air 360 mph and the PC-12 at 311 mph).
