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…
The most pressure it would experience would be the difference in internal vs external pressure. At 1000ft of depth there’s a pressure of 440psi. Assuming the sphere somehow managed a perfect vacuum that’s still well below the 6000psi compressive strength of high strength concrete, hell they would still have more flexural strength. The spheres themselves definitely wouldn’t be the weak link.
