[Nowhere Man]

No, the gravitation weapon was something I heard of on a movie, or such My design is the superbomb. (40GT. in a size small enough to fit in a truck)

40GT? Sounds like a Ford car. B-D Just kidding, sounds like you got a real Continent Buster there. B-)

[Rca2000]

Yes, it would be a Continent buster. In the script, I explain that it would pretty much eliminate ALL of North and South America, and the dust and debris cloud, would cause a nuclear winter for whatever remained of the the world, snuffing out the remainder of life, in under a month.

Although it is a fictional device, IF one could get an older 1960's or such sized 20MT warhead, And as in my story, use "neutron multiplication", to force nearly 100% of the atoms on the fuel, in BOTH the primary and secondary stages, to enter into the chain reaction,and progressively multiply the generations of chain reaction until all of the atoms had entered.... BEFORE the rupture of the casing-- Well, a 40GT blast might just be possible.
