I missed your post, but that link didn't really assuage any of my concerns. I'm not concerned about fallout, we're not talking about nuclear testing. I'm concerned about more immediate physical effects on the environment.
It's already been established that with enough dirt and water over something, it's pretty much harmless. But to use the shockwave of a nuclear detonation to clamp shut the oil pipe as Mac suggests seems far-fetched and dangerous. It seems like more would be involved than just burying it, crossing our fingers, and setting it off.
I don't know. I plead ignorance on this topic for the most part. It's just that based on what I know about nukes, using one to solve this issue seems implausible to me. Of course, the term "nuke" denotes alot of things. I probably wouldn't have any objections if someone said "high-powered explosives" instead.
