We seem to be discussing pros and cons of nuclear. But is this assertion of reasonably extractable uranium from sea water even true? Considering the source to be theregister, what I would like to know is whether the energy available as per the paper is really as big as claimed? or is it just clever math? Keeping aside the issue of waste disposal, are the costs really that low or is the cost cleverly buried elsewhere?

this is an old non-story. the energy required to extract the low levels of uranium from huge volumes of seawater outweigh the energy that uranium can produce as fuel for a nuclear power reactor.
