Nuclear Advancements.

Nuclear weapons are the most powerful and destructive technology ever created. From the first notion that nuclear technology could be harnessed to create a bomb, massive amounts of time and energy (as well as government funding) have been invested in further increasing the destructive yield of nuclear weapons. The process of development was carried out independently by governments worldwide. Despite the segregation of groups of scientists and secrecy surrounding their discoveries, design strategies and problems …

…can go on to start another fusion reaction and so on with unlimited yield. The most powerful weapon ever conceived was of a similar design. The Russian "Tsar Bomba" (King of Bombs) was a fission-fusion-fusion weapon with an additional fission jacket surrounding the third stage that would have produced a yield of at least 100 megatons if it were ever exploded. Without the additional fission jacket it still produced the largest nuclear explosion ever at 50 megatons.
