</div>You seem to be saying here that SBSP is a useless or actively<br>

good.

Environmentalists are conservative about the environment. I think<br>
they would be against SBSP for one simple reason: it would support<br>
more humans on the planet. I think they ignore that it would also<br>
help get more humans *off* the planet. I'm not sure exactly how they<br>
would react to that prospect.<br></blockquote><div><br></div><div>### Indeed, environmentalists are enemies of humanity, not just selectively conservative folks. "Conservatives" in the commonly used political usage at least have some human well-being in mind, environmentalists want our death.</div>

I'd also include Thorium reactors among the obviously good ideas (from<br>
an engineering perspective) which seem to get little political<br>
traction. I do have a good explanation for why Thorium has<br>
traditionally gotten little support: we wanted bombs, and Thorium<br>
reactors wouldn't help with that. Now that we don't want as many<br>
bombs, Thorium should be popular, but it isn't. The status quo bias<br>
that Anders brought up surely covers this, as well as the other things<br>
we are talking about here.</blockquote><div><br></div><div>### Once an industry is afflicted by a bureaucracy (the NRC, led by men who openly admit they want to destroy nuclear power), progress is impeded by something much more pernicious than mere intellectual conservatism. </div>
