There are several ways to accomplish the goal of extracting maximum performance from a solid rocket motor via the nozzle. The most common way – a convergent-divergent nozzle – is the standard for a reason: it’s the simplest, lightest most reliable way to do it. But there are alternatives that provide specific advantages. One of…
1/25 scale USS Enterprise, with complete interior. I don’t know where in the hell he’s gonna put it, but I applaud the effort. It’s made out of cardboard and paper, so its lifespan likely won’t be that long, sadly.
All evidence points to the forthcoming “Snow White” live action movie from Disney being something of a train wreck. It is a remake of the 19430’s animated classic, but it’s getting rid of pretty much everything… Snow White was originally prettier than the Evil Queen, now she’s objectively “meh;” Snow White was originally a love…
NOTE: The post below was originally from 2008. But for some reason, it seems like it might be worth a second look. The basic issue comes down to this… the Israelies had the poor manners to occupy Muslim territory. Granted, it was Christian territory before the Muslims conquered it, and Roman Pagan territory before the…
Humanity, that is. In terms of our ability to scare the crap out of African wildlife. Fear of the human “super predator” pervades the South African savanna In short: cameras and speakers were set up near watering holes and a wide range of sounds, including lions and other predators, were played. Animals got the hell…

But more-or-less practical “repeaters” were produced in time for the American Revolutionary War. Such weapons were proposed to Congress, but even though they worked they were very expensive. As…
Sadly not a lot of info on this. The Vulcan Aircraft (Houston, TX) “Starfire” concept from the mid/late 1980s used lift vans and vectored thrust for VTOL. Both military and civilian uses planned. Seems kinda reasonable, if perhaps a bit light on power. The basic design seems like it might be more practical today, though…
It seems that ad blockers nuke the Amazon links I put in my posts from time to time. The most recent blog post below (“Oh, no reason…”) had a few issues with such ads being rendered invisible and unclickable. If, like me, you have an ad blocker, you *should* be able to unblock specific pages…
UPDATE:well, this is annoying… the blog mangles the usual Amazon visual links. Grrr. Some items on Amazon that one might wish to procure. This one I can confirm works. Mine goes bonkers from time to time in antique shops. GQ GMC-300S Digital Nuclear Radiation Detector Monitor Meter Geiger Counter Radiation Dosimeter …
