The description needs to be edited:
ORIGINAL
Hamster Cage: This is a series of spun rings set at right angles to the rest of the hull. The rings must have a radius of at least 15 metres in order to produce a gravitational field. Machinery to spin a hamster cage uses 0.1 tons for every ton of spun ring. Unlike other designs, the hamster cage is usually set at right angles to the hull and installed in counter-rotating pairs, eliminating torque effects on the ship’s attitude. For each full percent of the hull which is made part of the hamster cage, the cost of the hull must be increased by +2%.
EDITED
Coriolis / Centripetal Hull - A series of spun rings set at right angles to the rest of the hull, the rings must have a radius of at least 15 metres in order to produce an artifical gravity field. These types of hulls may completely circle the hull, or they may need to be installed in counter-rotating pairs (multiple pairs are allowed), which eliminates the torque effects on the ship's attitude. Machinery to spin a coriolis / centripetal hull requires .1 tons for ever ton of spun ring (the ship itself will spin to provide gravity if the section completely encircles the hull). For each full percent of the hull which is part of the coriolis / centripetal hull, the cost must be increased by 2%.
Either coriolis OR centripetal label can be used. Hamster cage is pretty juvenile sounding, and shouldn't be used. I also modified the explanation because you can have multiple spokes or totally encircle the hull with your rotating section. The current description leads a reader to believe that you'd only install two at a time. It would probably be best to simply combine the double-hull and spun sections, as they are essentially the same.
But some questions that aren't answered - where is the cost savings for creating a hull that has no grav plating? This begs the question - how does the crew handle acceleration with no inertial compensator? If we are talking space stations, then no problem, it's not accelerating. But a spaceship WILL accelerate, and that changes everything. The only way for crew to occupy the spinning habitat rings would be for grav plating to be installed, which defeats the purpose of trying to generate a gravity field by spinning. With no grav plating you also are totally at the mercy of your acceleration/deceleration. Again, not a problem if your acceleration curve is pretty low, but if you are accelerating run at .1G, it's gonna take a LONG time to get anywhere. With actual spacecraft tech available, nobody would ever build ships of this type.
