1 Nuclear Machine : 74,550
(8 Distilled Water=150 each=1200, 2 sealed potion 600each=1200, 1 Pail Refrigerant=12,900 each. 1 titanuim alloy=23750 each, 1 compressor=35,500)
Total: 201,300
Time Elapsed: 1253 minutes

Total Amount Spent for Raw Materials: 287,220
Total Time Elapsed (based on wlodb information): 2640 minutes , So, 2640x150=396,000
Space Craft Total Amount: 683,220 but this is normally sold 1-2m since u have to pay for the efofort for getting the draft.
