Transcript:
We do have a plan for sustainably producing the rocket propellant,
which is actually almost 80% liquid oxygen.
So liquid oxygen you can get from obviously from the atmosphere.
And then we’re going with methane fuel,
which is 20% of the propellant,
but that you can make also sustainably long term from CO2 and water H2O,
which produces CH4 (methane) and O2 (oxygen).
So that’s the sort of sustainable long term path for rocket propellant generation, and that’s how it would have to be done on Mars, for example.
So not electrifying quite yet.
We do actually have sustainable power generation for some of our propellant generation already. But it’s a small percentage now, but it will be a big percentage in the future.
