The first plant of marijuana was planted on earth by aliens who wanted to save humanity. Instead of caffeine and amphetamine(for "ADHD") everyone including little kids should be force-fed marijuana all day. Marijuana must be legalized.

Do we even know what Sundial was? Or Gnomon for that matter. What their implementation might be? Was it just a massively staged, but otherwise orthodox thermonuclear weapon or was there something novel about it?
Carey Sublette suggested something last year that has really stayed with me. He said for a truly vast nuclear explosive 'all' (a rather over-subscribed word in this case!) you needed to do was dig a network of adits and interconnect them. Run a steel pipe down the centre of each and fill it with heavy water. Set off a fusion bomb at the mouth of each tunnel and the resulting explosion would be colossal--probably equal to a cometary strike I expect.
Obviously you couldn't drop that on an enemy. However it would work very nicely for a doomsday device if it were big enough. You could even salt it with cobalt granules if you wanted, although how much activated metal would escape the adits might be difficult to rely on. In my perception of the world that is what 'Dead Hand' really is!

More precisely the idea is to line the tunnels to make a proper radiation case and let the detonation of a single igniter bomb propagate through the whole network.
To couple a nuclear explosion with a yield similar to the KT Killer (Chicxulub) to the biosphere to have a similarly devastating effect it would need to be deeply buried so that the explosion energy could be distributed across a very large mass of crust otherwise the energy would escape into space (with some local atmosphere).
