It seems like every couple of months, some math smart muckitymuck wants to spoil our dreams of one day owning a fully operational Death Star. This time around it’s a pack of do-it-yourselfers from Lehigh University’s Economics department, and the price tag is a mind numbing $852,000,000,000,000,000 (or as they point out 13000 times the GDP of our entire freakin planet).
How did they reach that figure? Hit the Jump to find out.
Taking such factors in as the assumed diameter of the first one (140km, you know, moon sized) and that main material used would be steel mixed with building practices similar to modern day battleships they arrived at this dream crushing figure. The main culprit in ruining this fantasy is the cost of the material used. At 140 km you’d need roughly 1.08 x 1015 tonnes of steel and our current rate of extraction of roughly 1.3 billion tonnes annually, that means it would take 833,315 years to just get the raw materials you’d need.
This totally doesn’t take into account the price of getting the material into space, not to mention the labour costs and various permits you’d need. Just to have some young farm kid find that one thermal exhaust port that you didn’t have enough money to cover over and BOOM. All down the drain.
Man, those rebels were jerks.
