Because the folk at Centives.com have too much time on their hands, we now have a vague idea of how much it would cost to produce the Death Star in our current currency/economy. It’s not cheap.
Oh, and the cost of the steel alone? At 2012 prices, about $852,000,000,000,000,000. Or roughly 13,000 times the world’s GDP.*
*Gulp*
And how many Death Stars could we theoretically produce, regardless of cost?
[W]e’ve calculated that from the iron in the earth, you could make just over 2 billion Death Stars.
So, let’s see, $852,000,000,000,000,000 x 2,000,000,000 *pulls out calculator.*
Anyone got $1.69683934 × 1027 sitting around burning a whole in their pocket? If so, I think we could take over the known universe.
