There are ethical problems with ocean storage. What if the stuff leaks? Then it will hurt all nations on earth, not just the one responsible for the waste. And its harder to retrieve the stuff if needed, and harder to fix if something goes wrong during the process of stashing the stuff down there. Peak oil is not an energy crisis. It is a liquid fuel crisis.
If this is supposed to be an ethical problem, then why can a coal plant kill 75 people per year through air pollution and nobody gives a f*ck?! Get a grip on reality, folks. For details, see http://www.phyast.pitt.edu/~blc/book/chapter11.html
Why don't people care about coal? Because they're ignorant and scientifically illiterate, that's why. Peak oil is not an energy crisis. It is a liquid fuel crisis.
I don't think ignorance can explain the people's disregard for the deaths caused by coal. I rather think, these 75 people per GWa are a price most would be willing to pay. The problem is the wrong perception that a few grams of plutonium would kill millions if they came in contact with water, so people think a radwaste repository much more dangerous than it really is. Three decades of propaganda by liars like John Gofman have pretty much ensured that.
