Well, I'm sure controlled slow-paced mining is more energy efficient and will emit less carbon to create...

But I'm not stopping that guy. Go on. I'll just watch from a safe distance.

Going of the value in the paper and wikipedia it would take the energy used by all of humanity in two months.

[-] marcos@lemmy.world 1 points 1 week ago

You either spend a truckload of resources during decades to make a bomb that explodes releasing the same energy humanity spends in two months, or you spend a truckload of resources doing the end task at a slower pace for decades.

The later is guaranteed to require a smaller truckload.

Why is the second guaranteed to be smaller?
We know how nuclear bombs work. The majority of the energy comes from nuclear fusion, a highly exothermic process, that can (in the foreseeable future) only be used in bombs.
If we don't need to drop the bomb, but rather assemble it in place, it can just use deuterium as a fusion fuel. Deuterium can be distilled from normal water for much less energy that it generates in fusion.

Edit: mixed up fusion and fission in the first statement

The majority of the energy comes from nuclear fission

Yes, from an extremely inefficient fission reaction that can be improved by an order of magnitude by doing it slowly in a reactor.

Mixed up fission and fusion there, they sound so similar in English.
The comment talks about fusion.

[-] marcos@lemmy.world 1 points 1 week ago

Most of the energy does not come from fusion.

[-] anton@lemmy.blahaj.zone 1 points 1 week ago

It does in modern designs, the first time it happened was in 1952.

To quote Wikipedia:

The first thermonuclear weapon detonation, where the vast majority of the yield comes from fusion, was the 1952 Ivy Mike test of a liquid deuterium-fusing device.
