To Mars in a month

New Scientist: Solar super-sail could reach Mars in a month

Okay, so this is very, very cool. I do have a couple of questions, though.

First, would 60 megawatts of microwaves harm humans?

Second, how fast of an acceleration are we talking about? Would humans be able to withstand accelerating up to a velocity of 60 kps?

Obviously, my true concern is:

Will this technology get me to Mars?
