A German experiment proved that simple concrete spheres make fantastic batteries. Now, California plans to submerge a 9-meter diameter sphere in the ocean and is already planning versions of 30 meters.

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…

    I don’t know what depths we’re talking about here,

    From the article:

    The idea is relatively simple: hollow concrete spheres are installed at a depth of several hundred metres.

      Thanks, I missed that on my read through - 1000 feet of water is pretty serious pressure.

        The more pressure the more “equivalent head” power discharge potential. Separate “vacuum pump” (instead of bidirectional) could also have several stages to improve efficiency.
