The "market failure" part is that the technology has been available to the world for a while and no one in your precious "private sector" took up the challenge of attempting to make it.
Because the people in your precious "public sector" discouraged them, and in one instance (see above) flatly told them no, you cannot do it. And now, all the private sector money is tied up in delivering fuel to the technology that the "public sector" pushed so hard to get going. So, it's as I said all along: Not market failure, market
distortion, by government action.
Also, just because your world-view is completely polarized on this childish level of "gov'ment" vs. "Free-Market Utopia" doesn't mean that mine is. It doesn't mean that I'm going to worship the inverse of what you worship simply because I disagree with what you worship. I choose not to worship anything. And I'm totally willing to see and understand the government's failures, because I know that the government is really just a concentrated representation of the society at large; not some type of mystical monster or "Leviathan" with its own corresponding mythology. Our problem, and why you see our government stifling technological development is for the very reason that it is influenced, financed, and largely controlled by various oligarchical interests. In this case in point it was the various energy industries, most pronounced being the Traditional Nuclear Power industry.
