He was the best speaker from all in the convention. And he has a good sense of humor. I like the last Landis debate about artificial gravity in the ISS :)
21:40 false point i have calculated that at 0.1 c the sail would have been fully ablated in a few weeks due to nanometer size dust... you have to use precursor laser in the range of PW to protect it
I think in the end, systems integration will determine how spaceflight technology will evolve. I like the idea and reality that autonomous systems are sent ahead of humans; but this supposes we will send crewed missions into extreme deep space? I don't think humans are as riddle with vulnerabilities as most planners imagine. If 'wormholes' turn out to become manufactured structures at places like LHC; this may be the most significant payload we could send to another solar system ? I find it a whimsical thought of somekind of aircraft scaled hangar where we put a 'wormhole' and load it up with everything a new settlement would need to start up a civilization. It might just turn out that by the time all these technologies are doable, Earth will have all the human civilization problems solved and have no need for adventures that are being described in this lecture? I hope I'm wrong, because it seems so interesting, that human will not turn our backs and assert we know everything. Maybe the fantasy is that space travel will be better than cruise ship holidays, and people can get valuable work done; ultimately for more people to do the same... until you have adventurous, really smart humans all over the Galaxy.

here's the worlds latest cutting edge technology....wait the pointer doesn't work....wait the movie doesn't play....
