Well, actually, it is, kinda:)
A TL10 SM+9 transport vessel with a Fusion Torch drive has suffered a "fuel supply failure". It's drifting into a gravity well.
In emergencies the drive can manage 1G, 3G if they use water, but there is no fuel. There is, however, life support (Habitatx2).

Assuming they have the necessary skills and supplies, how many mps of fuel could they suck out of their life support system?
Would 15 tons of water per unit be too generous? Worth about 0.5mps @ 3G (a 3 second burn?) or 1mps @ 1.5G.

Thanks in advance for any feedback
