The parallels between the seventies and the current era are numerous. A shameful abandonment of allies, allowing them to be over-run by savages. A feckless and wholly incompetent President, in far over his head. A NASA in shambles, promising a New Thing but facing constant technical issues, delays and massive cost over-runs. An economy in deep trouble, with looming inflation. An energy crisis. Deep cultural and racial divisions. New York and other major cities being known more for their crime than anything else. And on and on.

So today, while out and about I stopped in a convenience store to get something to drink. Over the past few months there have been occasional shortages… sometimes they don’t have the syrup to make this or that fountain drink; or they don’t have straws, or they don’t have polypropylene cups, or they don’t have styrofoam cups. Various bits of shelf space bare from time to time.  All annoying side effects of the current economic conditions brought about by the pandemic and ridiculous policies that trash the ability of American ports to do their jobs. But nothing quite screamed “the 70’s are back, baby!” to me quite like today: I got my drink, pulled out a paper-wrapped straw, and unwrapped it.. to find a *paper* straw.

I haven’t seen a paper straw in 40 or more years. I didn’t like ’em then, because they turned into a soggy mess well before you were done with them. I don’t like them any better now, because of what they represent: an admission of failure. I don’t know if these straws hold up any better than they did 40+ years ago because as soon as I got to my car I swapped it for a proper plastic straw. But I kept the thing. It’s still there, mocking me, promising to bring on stagflation and a return of lime green polyester leisure suits, wide lapels, bell bottoms, perms.

Get ready for it. it’s coming back, like it or not.

This is an odd thing:

The Future of Custom Vehicles: Ford Unveils All-Electric F-100 Eluminator Concept With New EV Crate Motor Customers Can Now Buy

The “F-100 Eluminator” is just a concept car at this stage, with two 240 horsepower electric motors in a frame based on the 1978 F100. Ummm… sure. The title is perhaps a bit misleading: it’s the electric motor that customers can buy, not the complete vehicle.

I guess it looks good (except those wheels… the large-diameter hubs married to narrower sidewall tires always seemed like a bad idea for a vehicle designed to actually *work*). Just strange to see a 1970’s pickup turned into a modern electric.

But so long as Ford is going to the bother of making electric-powered concept cars based on decades-old designs, I have a suggestion:

A few modestly interesting videos, especially if you want to depict rapid depressuization of a high-flying aircraft.

First a test with a jetliner. This seems to be a 7 psi pressurization check carried out on the ground. Rather than being pressurized at somewhat less than sea level pressure and blowing down to very low pressure at high altitude, this started off at *more* than sea level pressure, and blew down to whatever the local air pressure was. The end result is more or less the same; the structure of the aircraft undergoes the exact same stresses (which was probably the point of the test). The visual response is, *I* *think,* more pronounced here than it would be at altitude, because the high pressure ground test likely had more humidity to start with – and thus convert to visible cloud – than a high altitude scenario would have. Bonus: best YouTube comment had to be… “This must be the pilots first day. Putting the clouds on the inside of the plane instead of the outside is a rookie mistake.”

 

And another depressurization test, this time of a U-2 pilot and his “space suit.” You can see the cabin fill with vapor briefly… and you can see how that carefully fitted suit doesn’t fit worth a damn anymore promptly after depressurization:

And another depressurization of a test chamber (from 8,000 feet altitude to 18,000), showing the insta-cloud:

Portlan, Oregon, paragon of progressivism and police-defunding, *used* to have a Coast Guard Cutter as a museum ship, the USCGC Alert. Then it got turned into a homeless encampment. Then it sank.

Rather than spending taxpayer funds on police, civic improvement, restoration ans sustainment of history and dealing with abandoned military vessels in their waters, the Portland government decided to be Portland.

The modelling is nearly complete. Unfortunately, the fully assembled version of the CAD model is so complex that none of my computers would even attempt to render or shade it; all I seem to be able to get are wireframe images. That’s what I get for being poor, I suppose. The shuttles are themselves each as complex as many of the CAD models I’ve made.

Half off the price of their books, plus free shipping. Woo! So if you have any money left over after you buy suspiciously large numbers of copies of “SR-71” and “B-47/B-52,” go get you some books about ships and such.

And if you end up saving some cash on a haul of books, why not show your boundless appreciation…
