By Micheal Anissimov Assuming a 1-megaton nuclear weapon, what are the optimal delivery points to maximize global damage and chaos? We are assuming a 1 megaton bomb due to simplicity - this yield is about twice that of the most powerful fission bomb produced by the US, the Mk 18, which used 60 kg of enriched uranium. With nanofactories, building extremely high-quality centrifuges will become easy, making large quantities of enriched uranium accessible to any organization with uranium ore. We will be able to do with a few centrifuges what previously required hundreds or even thousands. A few facts about uranium: uranium ore is more common than gold, mercury, silver, or tungsten, and is found in substantial quantities worldwide, including in southern Australia, Africa, and the Middle East. It is the 48th most abundant element in the earth’s crust. Pitchblende uranium (1% pure) is available on eBay for approximately $20/kg. The US Department of Energy has stockpiled 704,000 metric tons of...
