Hi. I’ve had an idea to handle stability by basically building the platform on a giant gyroscope. I figure, if the inner platform can stay still despite the outer ring motions, then if the outermost ring is made into a hull the rings can take wave motion while the platform is stable. According to the mighty Wikipedia: “Since external torque is minimized by mounting the device in gimbals, its orientation remains nearly fixed, regardless of any motion of the platform on which it is mounted.

I figure this would probably be rather expensive, and the platform would need some sort of fluid support to stay still and avoid snapping the ring connections. On the other hand, with a rubber or plastic top that fluid support can be the water supply, and the space could be used to store things you don’t really care much about moving around. I hope this helps.
I wasn’t actually thinking of manually spinning the gyro. I was thinking the waves would move the outer rings and the inner platform would stay still. This would need some really, really strong, frictionless joints- either ball bearings or magnets. This way, you don’t want to move them back- you WANT the rings to move with the waves. As for keeping the whole contraption in place, I was thinking large motors (probably connected to a few power systems) on the outside of the outermost ring. The contraption would just drift until the captain decides to move it back.
As for getting it in place, I was thinking of building the main platform on a privately owned dock and then loading the rings and outer hull, probably in sections assembled around the platform and then rotating them for connectivity. The outer hull could probably be assembled in the water as a geodesic dome.
As I said, though, this scheme sounds rather impractical, especially considering my (lack of) understanding of gyros. Thanks for your input.
I think there is a possibility of giant gyroscope reality. If the wheel were cast in place, with a special design, where the core had coordinated rebar into a magnetic pattern that would favor generation of electricity, and receive pulses of electricity, one could use small pulses of electricity to start the big wheel spinning. and wind, and motion… I know of several ways to gather small amounts of electricity, and soo…… if you know about the guys using heavy gyroscopes as batteries.. you may have thought of that too…
I was more thinking the wave energy would transfer to the rings and the platform would float still in the water. I’ll have to do some small-scale tests, but I doubt it’ll actually work like I was thinking. Still, the electricity thing is new to me, and if it can be done, then great!
My thought was to put a huge flywheel in the base of a spar structure and spin it. This would prevent any type of tipping and take advantage of a weight we need for other reasons anyway.
Spinning could be done slowly; as long as you add a little more energy than friction takes away your structure gets more and more stable every day. Energy harvested for temperature differential should be enough
