“Which isotope has a critical mass under 5 lbs?”
Unobtainium, of course!
Davy Crockett was a dirty bomb. No Nuke explosion.
Critical mass or implosion devises are not small.
I don’t believe a true nuke explosion device can be that miniaturized.
Implosion is method to reduce the amount of core material, but it uses shaped charges to get past sub critical mass reaction.
Dirty bombs? Yes.
True nuclear explosion, no.
Sure, those are certainly a threat.
Evil still exists and nature can be used as a weapon.
It is utter bullshit. Livermore lab has failed to demonstrate fusion with it’s 4.5 billion dollar laser. It’s in a building the size of two football fields and 6 stories high. The power from the fusion, if it worked would have been less than a glazed donut.
Not going to happen.
Krispy Kreme or Voodoo?
Never say never.
You can’t even make a dirty bomb small since they is just nuclear waste, and the size of the exclusion zone is set by that amount of waste. Fukujima tells you the scale that is required. The expended core of a power reactor.
I don’t have any interest in arguing about this.
I have some knowledge of it.
agree
It’s nice to know you claim foreknowledge of every advance in science and technology.
Can you give me some hints? I’d like to add to my patent portfolio...
In fact, “miniature” nuclear bombs already exist, weighing less than 20kg and transportable by backpack. The soviets had even a design in a suitcase that can be lifted by hand. But it’s a classic fission bomb, with proven technics, no fancy laser-fusion-nanotech-whatever vaporware.
as per who?
Anti-matter initiated D3-D2 fusion—but if one already has sufficient anti-matter whats the point?
Side-On laser ignition—Friedwardt Winterberg.
Thanks, will look it up when I get some time free to absorb it.
Wikipedia and other sources contain statements such as, “The M-388 round used a version of the Mk-54 warhead, a very small sub-kiloton fission device. The Mk-54 weighed about 51 lb (23 kg), with a yield equivalent to somewhere between 10 and 20 tons of TNT—very close to the minimum practical size and yield for a fission warhead.”
I see a video of text firing the device and it looks like a significant explosion to me.
I see a picture of a man holding the warhead with a yield four times as great as the largest conventional bomb produced by the Allies in the Second World War.
Davy Crockett (nuclear device)
https://en.wikipedia.org/wiki/Davy_Crockett_%28nuclear_device%29
The M-388 round used a version of the Mk-54 warhead, a very small sub-kiloton fission device. The Mk-54 weighed about 51 lb (23 kg), with a yield equivalent to somewhere between 10 and 20 tons of TNT—very close to the minimum practical size and yield for a fission warhead.
The M-388 would produce an almost instantly lethal radiation dosage (in excess of 10,000 rem, 100 Sv) within 500 feet (150 m), and a probably fatal dose (around 600 rem, 6 Sv) within a quarter mile (400 m).
The units were deactivated in mid-1968.

So the effective kill range is 500 ft-1/4 mile. This makes me ask the question, is it a fission device because of it's explosive capability or the radiation it emits?
