Silly summer thoughts 3: Dune Shields

First, a bit of news: I’ve got another guest post up on Antipope, if you haven’t already seen it.  Go have fun with it, if it’s your sort of thing.

Now back to summer silliness; why not pick on Dune again?  It’s a fun target at the moment, especially since it gives this distorted impression that magnates and aristocrats could be part of  a breeding project to produce a superhuman messiah, even though rationally we know that regression to the mean seems to be a more common outcome for human reproduction(except for inbreeding, which gets rather worse).  The current administration in Washington is a great example of how each generation in a wealthy family gets smarter and more talented.  Or not.

In any case, for summer silliness, I give you the shields of the Dune universe, which apparently are spherical shells of force (or weirder, if you’re David Lynch and filming the novel), that slow down objects passing through them to 6 to 9 centimeters per second (this from the glossary in the original story and here) .

Silly summer thoughts, Part 1: new Dune movie

Just a brief one.  I recalled today that a new adaptation of Dune is currently in the works, random deities help us.  I’m not a huge fan of the series, but I did like the original Dune, for what it’s worth.  It’s gotten rather more humorous as I found that Frank Herbert’s idea of a dune was based more on his coastal Oregon dunes than on the Sahara, that his idea for the sandworms came from maggots eating a mushroom, and the Bene Gesserit and their blue eyes were, erm, inspired by his ingestion of (hopefully) non-wormy mushrooms.  Those were the days.

Thing is, I’m a grumpy ecologist.  I’m still trying to figure out how you get their metabolism to effectively run backwards so that they exhale/fart oxygen (I guess they breathe in CO2?).  And a sandworm hundreds of meters long snacking down on a human is about as close in optimal foraging strategy as humans chasing after individual ants.  Ant hives, yes, but individual ants?  Anteaters don’t bother with them, and sandworms shouldn’t bother with individual humans thumping across the dunes.

Still, I wanted to have a little fun, it being a hot afternoon in July.  So I started thinking about those still-suits, which capture and filter sweat and urine and recycle is so that the wearer can drink it again.  Talk about a sweat bath!  If you’re wearing one of these damned contraptions, you’re going to get heat stroke in short order, unless there’s some mechanism for getting the heat out of the recycling body fluids and off into the air.  I may be wrong, but I think that takes energy?  And aren’t electrical signals supposed to attract sandworms?
