Nuclear Explosions for Large Scale Carbon Sequestration

Some people will love this idea, it fits with the big ol' simple fix so no worries, we'll just keep on keeping on ... Also somewhat NIMBY for most who don't want their tax money to help deal with the situation that might not be real ...

I'm greatly amused, it reads more like a movie plot or a good April fool's joke ... what could possibly go wrong. Drilling in depths over 3 miles of water isn't that easy. Also water is slightly absorbent hydraulically, but not that much to quell such a high energy blast.

Blasting a large channel in suitable coastal mainland material, (maybe along some strategic line into the country) results in a structure that could be used for shipping and moving the resulting rubble some distance out from the coastline to form a deep protective sea wall along the coast makes a lot more sense as it has more value. The wall would also for a narrow sea suitable for shipping and recreation, the wall additionally creating a secure border while it's undeveloped. Of course after some years, the first built parts of the wall once the bulk has weathered and settled, might be suitable for niche farming ventures or a nature reserve.

>Detonating a 81 Gt nuclear device could cause a global catastrophe if done improperly. Simply burying a nuclear device in a basalt deposit would cause this catastrophe. However, deep water is incredibly shock absorbant.[sic] By buring [sic] the nuclear device kilometers underground under kilometers of water, we can be certain that the explosion will first pulverize the rock then be contained by the water.

We propose burying this device beneath the Kerguelen Plateau in the Southern Ocean, 3-5 km into the basalt-rich seafloor and 6-8 km below the water’s surface. Under these parameters, there is approximately 800 atm of pressure to absorb the energy. Additionally, nearby currents like the Antarctic Circumpolar Current can distribute the particles for accelerated carbon sequestration.

Additionally, the nuclear device should be designed to minimize its long-term radiation effects.To do this, a standard fission-fusion hydrogen bomb design is sufficient. The basalt should absorb and trap in the majority of the radiation to the local area.
