    OTEC, the temperature gravity wheel can be modified to OTEC (Ocean Thermal Energy Conversion).
    Ten years ago, I was a bit bored and built one. It would need to be modified. I have some ideas for it.
    Here is a video of the one I built: https://youtu.be/gdmU6EEAnXI

      ^^^ Thanks, so many possibility just a matter of finding and implementing the right one.

          OTEC is awesome, but really best suited to deep equatorial waters where there's a big enough temperature difference to give decent thermodynamic efficiencies. If you have a seastead in shallow water like the Gulf of Thailand where it's only 50-75m deep and there's only a few degrees temperature difference, I suspect the efficiency would be too low to justify the cost.

          Boosting with solar thermal collectors is interesting (I hadn't heard of it before); I'd be curious to see how it compares cost-wise with solar + batteries, though.
