A very oversimplified cost estimate for the Death Star over at Gizmodo.
Of course, this is ridiculous. If you were building a Death Star, you certainly wouldn’t bother trying to schlep the raw materials up out of the gravity well of the Earth. You immediately cut $12.79 septillion out of your cost estimate if you just start mining asteroids. That’s an almost 82% reduction out of this budget, right there.
Come on, Gizmodo. You can’t give a guy huge nerd points when they miss such a blatantly obvious scrounging opportunity.
