I wonder what the greenhouse gas emissions will be like for the Earth-to-Earth trips. Ironic that the display showed a snow-capped mountain after the E2E animation.
Earth-bound BFR flights could be net zero emissions if SpaceX uses solar energy to generate methane from atmospheric carbon dioxide, as Musk discussed in the talk.
How much does that cost, compared to existing methane sources? I imagine that is only viable if it is comparable in cost.
It's the default Mac background that I assume they were running the presentation off of.
He addressed this. You can make methane from CO2 and water, so it can be carbon-neutral.
