This is kind of a disappointing 'doomsday machine', it's basically an over complicated and/or machine.<p>I was hoping for at least a stockpile of nuclear weapons in a converted cobalt mine (<a href="http://en.wikipedia.org/wiki/Cobalt_bomb" rel="nofollow">http://en.wikipedia.org/wiki/Cobalt_bomb</a>). Get a few hundred multi-megaton nukes wired up together and if the country gets nuked it blows, kind of like a dead-country's switch. If you generate enough radiation you can essentially guarantee you wipe out your enemy by wiping out the majority of life on Earth.<p>Essentially any large-scale nuclear war can potentially render the world uninhabitable. The amount of soot put into the upper atmosphere by the detonation and widespread forest fires would potentially eradicate all ozone, meaning heaps of UVA, UVB and even UVC. The concern is that we only receive 1.3% of the suns UV's thanks to the Ozone layer and can still receive major burns. Consider that it takes ~30-60 minutes on a bright day to get a burn (at least it does for me), after a major nuclear war it could possibly take less than a minute of direct exposure to get a sunburn and it could possibly take 100 or more years for the depleted ozone layer to restore itself.
