We have discussed this previously in depth.
The bottom line is that you cannot carry enough energy to get anywhere useful in human-scale times.
Gathering energy on the way simply isn't enough.
Human beings (as human beings) are not going to colonize any other solar system. Human beings will go extinct on Earth, not even having permanent sustainable colonies in the solar system.

The more interesting problem is that people REALLY believe in a star-trek-like future... Their belief is extremely passionate and quasi-religious. These same people are HUGE supporters of science, technology and living rationally.
