Clothes are throwaway items now. Back In My Day, socks with holes in them were repaired; now, often enough, shirts are worn only a few times then tossed. Sometimes sent to thrift stores and the like, sometimes simply thrown out. But thrift stores have more clothes than they know what to do with. So often these discarded shirts and shorts are boxed up and shipped to third world countries where the trainloads of discards can be used to eliminate the local indigenous clothing production industry; this is why you often see some illiterate tribesman wearing a t-shirt emblazoned with the logo of some midwestern high school baseball team. At some point I suppose this global traffic in clothes might end, but likely not before many places lose the knowledge and ability to make their own clothes.

Anyway, it seems to me the obvious solution for this is so obvious that it’s obvious: FIRE. Clothes are largely made from plastic and cotton; these will happily burn. Sure, some unfortunate fumes will be generated, from the toxic to the CO2;  but if incinerated in a large and modern facility this can not only be done fairly cleanly it can also generate a lot of power. Use the combustion to boil water, run the steam past turbines, shazam, electricity. But for whatever reason we don’t much burn our garbage these days, preferring instead to burn rocks and goop we dug up out of the ground. So what happens to all these discarded garments?

If you’re Chile, you dump them in the desert. There it can be picked through by locals and by a company that is trying to separate out the various materials and make something of them.

A recent satellite photo shows the pile:

It’s a little difficult to judge scale from that. At lower left you can see an urban area; the pile is clearly a number of city blocks in expanse.

An article from 2021 shows the pile (from the ground) as it existed in 2021. It was *huge:*

Here’s the location on Google Maps, satellite view:

Interestingly, the Google Maps satellite photo, which seems to have been taken in July of 2022, shows just bare Earth. It seems that there was a huge pile in 2021, it was dealt with in 2022, and its huge again in 2023. So processing seems to be keeping up. Or… when the photo was taken in 2022, the pile had been buried in the dirt.

Even with a specially made setup and at close range, it’s difficult. This should drive home the difficulty and impressiveness of hit-to-kill interceptors that take out incoming warheads or missile from tens of *miles* away at closing velocities far greater than those of mere bullets.

Also: bullets don’t as a rule fuse together; rather, they explode in a shower of flattened lead fragments.

Back in the Good Old Days of above-ground nuclear testing, a series of solid propellant smokey-trailed rockets would be launched just before detonation. They would leave vertical trails in the sky near the detonation. The video below explains just what they were for, as well as some of the physics of the detonation itself… the radiation front and the shock front. It’s interesting.

Both the phone and the typewriter arrived today. The phone, as can be seen, seems to fit just about perfectly, indicating that the Samsonite briefcase is the correct one (though a number of virtually trivial details are different). The phone has a cord that seems to be pretty permanently attached, but I am loathe to just lop it off. My goal is to keep all the vintage bits as intact as possible, so I’ll either disassemble the phone or go straight to making a silicone mold of it and casting it in fiberglass. I hope to remove only a few keys from the typewriter, assuming I can figure out how to remove them without damaging them, then mold/cast resin copies. Other than a cracked frame the typewriter seems intact and functional. And while there is about zero chance I’ll ever use a typewriter again… I cringe at the idea of wrecking such a nifty bit of functional analog mechanical genius.

The phone and the keys are the wrong color, so casting copies seems to be the correct way to go in any event. This would also open the door for a very limited run “kit” for those vanishingly few who want this. I plan on making the parts out of a combination of cast resin and fiberglass; hand laid up fiberglass cloth components would be strong, light and *hollow,* allowing those with a mind to to install electronics. A functioning keyboard and monitor would be spectacular, though a functional fiberglass phone seems maybe a bit dubious.

 

 

 

 

Note the obligatory feline photobomb.

The first artifact has arrived, a Samsonite briefcase. I am *largely* certain that this is the correct case; there are certainly a largish number of them readily available on Ebay. There are some minor differences between this one and the prop, most of the differences explainable as modifications: the key locks have been removed and replaced with featureless aluminum disks/cylinders; the tabs on the prop have concave ends rather than just squared-off ends. There is a small placard affixed to the middle of the briefcase… I can see “Honeywell,” then something that might be numbers, and then “EXECUTIVE.” The interior lining needs to be removed and the whole thing cleaned, the metal polished and the metal base that the handle is fixed to painted black.

And, of course, the current residents evicted. This took about five seconds; it is a box, after all.

I will wait a little bit before launching into a full preparation. The intercom/phone should be the next item to arrive, and if it fits in this case as it should, then I’ll be off to the races. If it doesn’t… well, I’ll need to rethink the case, I guess. Pretty confident, though.

Ever since the early sixties there have been ideas about “inspector” spacecraft that would check out other satellites. This would be done to see just what some foreign satellite actually was…r econ, communications, navigation, weapons platform. But actually doing it has not but done too often… at least, it hasn’t been *shown.* But here are the results of one commercial satellite – the Worldview-3 earth observer – looking at a Landsat from a range of about 100 kilometers. The imagery is remarkably clear.
