If you had $US15.6 septillion and 94 cents in your account, would you save the world from the economic crisis or build a Death Star, destroy the world, and move on to invade the galaxy? A guy called Ryszard Gold—who probably is an alien villain from the Outer Rim planets and got a 49-point score in our Geek Social Aptitude Test—made the calculation of the most basic Death Star's price with current materials and space transport costs here on Earth. Here's a quick summary:
The total: $US15,602,022,489,829,821,422,840,226.94.
Yes, that's a whooping 1.4 trillion times the current US Debt. Or a sightly more meaningful number: 124 trillion years of war in Iraq.
That will only get you the very basic model of Death Star, no options, no GPS, no radio, no leather heated seats, no mega-laser to obliterate planets, no turbolaser towers, no computer systems, no miscellaneous life support systems, no crew quarters, no turbo-elevators, no energy generators, no showers, no air conditioning, no Darth Vader's jacuzzi, no Emperor's home theatre system, and no bloody canteen. And don't get me started on the cost of all the lunch trays and the constant supply of penne all'arrabbiata and peas needed for all the Death Star personnel*. That will probably double the final bill, coupled with the construction costs, for a total of more than $US31 septillions.
As for the answer to the first question, there's no doubt about it. But then again, I always liked the Emperor's robe. He goes naked everywhere and nobody notices.
