Flipping the whole hab was pretty much the way I saw it too, it is just the

It would probably need to be pelletized before it could be sent into the
reactor/engine. Just as easy to build a giant tank and fill it full of

I don't see this at all.
Scenario A Scenario B
1 G thrust 1 G thrust
3 month burn 3 year burn
Then delta v of Scenario A is less than delta v of Scenario B, and
total trip time of Scenario A is greater than Scenario B.
The only constraining factor is can we carry sufficient propellant to
maintain continuous thrust? (There is also the little problem that B
requires more engine than A as well...)
