1) If he said “nuke” I doubt he really meant “nuke”.
2) If this conversation took place, like others said, it sounds more like just sounding off ideas to prevent hurricanes from harming people and cities
3) We have some technologies such as seeding clouds for rain. Dunno how well any of that works
4) I am no expert but I doubt even a “really big bomb” would work. Hurricanes stretch something like 300 miles wide. A nuke might work but sounds absurd. Perhaps a large number of large bombs could break the storms up in the atmosphere? I dunno.
5) How about other technologies such as frequency waves to disrupt the formation of hurricanes?
6) All ideas are worth thinking through. Most of them will have unintended consequences I would imagine. I don’t think anyone would want to test nuclear explosions.
A nuke might have a better chance of knocking out a tornado. Oh yeh, and a whole lot of other things with it too.
But if there could be a targeted, non radioactive explosion to blow off the top of the tornado to disrupt the rotation what a benefit that would be.
