This AMA is about SpaceX not Tesla.
Yes Elon is doing an AMA, no it's not about Tesla so please stop posting • /r/teslamotors
Elon's team told /r/spacex mods that he will not be taking questions about Tesla so please stop promoting the AMA
Trolling level: lame. None of those questions will get answered, just ignored you Elon. But there will be discussion on reddit, far far down on the page since the questions that do get answered by Elon will be read and upvoted.
Initially, glass panes with carbon fiber frames to build geodesic domes on the surface, plus a lot of miner/tunneling droids. With the latter, you can build out a huge amount of pressurized space for industrial operations and leave the glass domes for green living space.
I had the same reaction as you when I read what Elon said about geodesic domes with glass panes set in carbon fiber frames. I can't answer your question, but can speculate that it should be possible to monitor cosmic ray intensity so that the domes would be off limits at times but accessible when safe, like when the sun was low on the horizon and at night (again, I'm speculating here).What I'm wondering is, could glass panes provide adequate radiation shielding? Living on Mars would be a lot less fun, in my opinion, if it has to entail staying below ground the great majority of the time. It sure would be nice to have living spaces with views out onto the Martian landscape and of the sky, but only if cosmic and solar radiation could be adequately blocked.
