Ion drives aren't under-researched, really! They are common, repeat *common* for comm satellites. The Dawn mission to Vesta has been using them for years. SMH

Yeah, except that they're totally different. I'm trying to see how they might be the same ... is the low thrust what you're referring to?

So the appropriate response to military regimes is to wait until it's economically desirable for someone else to put pressure on the government? Bashar al-Assad and Kim Jong Un are in violent agreement with you.

Are you actually calling a military take-over of the government "paranoia"? You do read the news occasionally, right? I also assume you've heard the term "coup".

I lived through those times, too, and in the town right next to Manhattan Beach. And I fell for it. But the evidence here is FAR more damning. I mean, pictures? Semen on spoons in the trash? That's not at the recovered memory level.

You're not a character in one of Neal Stephenson's novels, are you? Because you should be.

Hey cool, I'm a sharecropper too! And an MD who never went to high school.

Well, not that I agree with Moose, but ... everything that comes out of Hollywood?
