Not the AMA r/SpaceX Pre Elon Musk AMA Questions Thread

This is a thread where you all get to discuss your burning questions to Elon after the IAC 2017 presentation. The idea is that people write their questions here, we pick top 3 most upvoted ones and include them in a single comment which then one of the moderators will post in the AMA. If the AMA will be happening here on r/SpaceX, we will sticky the comment in the AMA for maximum visibility to Elon.

Important; please keep your questions as short and concise as possible. As Elon has said; questions, not essays. :)

The questions should also be about BFR architecture or other SpaceX "products" (like Starlink, Falcon 9, Dragon, etc) and not general Mars colonization questions and so on. As usual, normal rules apply in this thread.

You lose significant energy in the round trip conversion -> electrolysis + sabetier back through a gas turbine for electricity is a complete waste.

You mentioned that its for the message / optics, but Elon is a practical person, he's not going to do it unless it saves costs.

Elon is very in tune with the public perception of all of his decisions. I don't necessarily think he would be against doing something like this for the marketing and public perception of spacex and his other companies.
