What the US gets from the Russia-Ukraine war

A lot of people think that the US is simply throwing money away. These people are wrong.

 

The majority of the weapons that the US is giving to the Ukrainians are old stock, stuff that would have gone to the incinerator or the scrap heap pretty soon anyway. If you expend a million-dollar weapon that you were otherwise going to simply throw away, you haven’t lost money. But if you expend that weapon for a practical purpose, you not only affect the course of the conflict, you also *learn* things.

A couple of tweets showing the spectacular state of American cities today…

Someone needs a tazin’…

And New York City? Don’t go there.

Here’s a fun related article:

Remote Work Is Poised to Devastate America’s Cities

People no longer *need* to live in big cities quite as much as they used to. The pandemic helped this process along by forcing people to work from home; and once people – and businesses – realized that people could work from *anywhere* and not have to deal with commutes and the nightmare that is the urban area, a lot of people *wanted* to bail out of big cities. Turns out Poop Central, AKA San Francisco, is seeing a *lot* of empty offices as people pull the D-rings and flee that rathole.

The last ten years or so have seen massive denigration of long-established fandoms. Star Trek, Star Wars, LotR, etc. These fandoms have deep and beloved lore, and many of the modern producers simply don’t care. Why respect the canon, when there is a message to deliver?

 

Fortunately, this is not always the case. Sam Witwer is an actor probably best known for voice acting. He’s voiced Darth Maul in the “Clone Wars” and “Rebels” series, and “Starkiller” in the “Force Unleashed” video game, where he also did motion capture. It’s that latter one that’s of interest here. Turns out that he was knowledgeable in Star Wars lore, and knew how to apply that knowledge… and the director of the game knew to respect that. (This was a 2008 release, before the modern age of garbage; but witness Henry Cavill’s love of Warcraft 40K secured him a post-DCU future.) Behold:

Something like 15-20 years ago I bought a 1/18 scale P-47D “Ultimate Soldier” toy. This line of large scale accurate fighter planes was sort of peak Golden Age Of Toys For Adults, even though they sold for a reasonable price at WalMart. They make great display pieces even without structural modifications or repainting, but they are generally screaming for such.

 

Anyway, the P-47D spent years on a shelf in my shop in Utah. From time to time it caught direct sunlight. This discolored the paint *slightly,* but it turned the originally crystal clear canopies milky white. I’ve left them in the dark for some years to see if that would help… nope. I boiled them… nope. I nuked them, if perhaps briefly, with UV; no change. Anybody got any ideas? Why did this happen? How can it be reversed? Scrubbing has shown that this is not a surface feature, but seems to be throughout the plastic.

At some point, recasting them with crystal clear resin might be the only solution, but it’s not one I’m fond of. None of the other canopies did this, so it would seem these two pieces of plastic came from a bad batch.

The constantly evolving “Enzmann Starship”

The “Enzmann Starship” is named after Robert Enzmann, who “designed” it decades ago. Just exactly *when* has been an issue of some confusion in recent years.

It first came to light in the late 60’s or early 70’s, with claims that he thought it up around 1964 or so. The design is unique: a giant spherical ball of frozen deuterium fuel at the front, followed by a cylindrical ship, ending with a series of Orion-style nuclear pulse engines. It was an *ok* concept for a practical starship, though relatively recent analysis presented in the Journal of the British Interplanetary Society argued that it was not nearly as good as imagined. It became something of a sensation in the 70’s after appearing on the cover of “Analog” in 1973.

Nothing has ever been produced, so far as I’m aware, backing up the concept with any sort of detailed design of analysis until that JBIS paper. No reports, proposals, pages of math, from Enzmann seem to be available… just text descriptions of a few sentences and some art. And that’s fine. But in recent years the claims have become more and more expansive. Enzmann, near the end of his life, claimed that the design for a nuclear-pulse vehicle dated not from the time of the Orion program, but back to the *40’s*.

I spoke to Enzmann on the phone a few times over the years. He was enthusiastic, verbose… and baffling. He made lots and lots of claims about having worked on this or that amazing program, but when asked for verifiable details… it was classified. Those who have picked up his mantle and are trying to carry his torch seem to be following in his footsteps there, continuing his claims without much apparent criticism. I’ve recently engaged their twitter contact to get some sort of verification of his claims… but we have now reached the point where not only am I convinced that no such evidence will be produced, I feel no reason to assume anything remarkable is true at all. Behold:

Claiming that nuclear powered aircraft were actually built in the fifties and then buried in a mountain? Yeah… no. I’m out.
