I agree with Jason (and, I think, Martha) that interstellar travel "as seen
on TV" would require tremendous amounts of energy, and that when it comes to
energy, humanity has a long way to go in almost every regard.
I'm optimistic that Secretary Chu will take a good broad look at energy, but
I don't think we're going to get starships during this administration.

You have your answer here. Send a nano ship to a star system, it can travel
slower then .1C and once it arrives, it can use the local material to
create bigger machines. Then take it from there. |

I like it, because it's also relatively cheap and doable within
existing technology.
