Storing renewable energy sustainably and efficiently is one of the major challenges of our time. A team of German researchers is proposing a revolutionary solution: concrete spheres immersed in the ocean floor. Their potential is such that California is preparing to test a large-scale prototype. A simple, ingenious concept The…

    Like a battery, it’s not scalable as a one off, but it may be as a modular mass produced item.

    Or maybe like a wind turbine. You’d have a field of them comprising a power plant. If you lose some individuals, who cares. If you need to do maintenance you can take one offline or entirely replace it without really impacting the power plants output

      An easy manufacturing method would be to 3d print in plastic a double walled shell, with fill holes for concrete, and mounting chanels for motors. Plastic “lining” would provide salt water protection for the concrete.
