  1. Cryo vs non-cryo is not the issue here, neither storables (which have to deal with strict environmental regulations) or cryos work if they can’t be fed into the engine because the fuel is pushed towards the top of the rocket. Even a full tank can have areas of low and high pressure.

  2.  @timoclark8367  Sure… But there are no Helium/gas tanks that go to the top of the tanks either here. Maybe those ones near the engine are Helium tanks, but they don’t seem to have any connection to the top of the tanks. There’s clearly pipes for the top tank to the engine, just not to the top of the tanks. Either way, it’s just an example of the lack of detail/thought behind this plan more than anything else.
