Most of The Physics of the Death Star is pretty much Greek to me (art degree!) but long story short, the amount of energy the Death Star needs just to blow stuff up:
It’s a solid week of the sun’s entire power output. Dumping it in about a single second, as required to blow up Alderaan, is a very, very impressive feat. Doubly so when you take into account the fact that the binding energy is just enough to dissociate the planet into a diffuse cloud. If you want to actually blow the thing up into pieces flying out at many times escape velocity, you need much more energy.
So how much would it take to move that thing around? Even in zero gravity? How about the lights? Interior gravity? Refreshers? Mouse-droid charging stations? On second thought… I don’t want to know. (via)
Martin Anderson over at DenOfGeek.com muses on cellular memory, integration, and other scientific explanations, based on other genre works, for how the titular system of Joss Whedon’s upcoming show, Dollhouse, might work? Will Eliza Dushku eventually realize she’s actually Faith? Dollhouse premieres February 13, 2009 on Fox.
No, USA Today is reporting this one straight, complete with comments from Howard Roffman. The Force Trainer “uses brain waves to allow players to manipulate a sphere.” Naturally.
No, you’re not tapping into some “all-powerful force controlling everything,” as Han Solo said in the movies. But you are reaching out with mind power via one of the first mass-market brain-to-computer products. “It’s been a fantasy everyone has had, using The Force,” says Howard Roffman, president of Lucas Licensing.
…In the Force Trainer, a wireless headset reads your brain activity, in a simplified version of EEG medical tests, and the circuitry translates it to physical action. If you focus well enough, the training sphere, which looks like a ping-pong ball, will rise in the tower.
Call me when they start making the toy lightsabers with real light, okay? (via)
