The rig is not just on the ocean. It uses the ocean.
The Ocean-Floor Battery is the grand visual concept behind SolarPowerRig.com. The old oil platform sits above deep water. Solar panels collect power on the deck. Compressors turn some of that power into stored pressure. Gravity blocks move through the water column. Cables, controls, winches, pipes, and lift systems connect the platform to equipment below.
In plain English, the ocean depth becomes part of the storage system. The vertical distance between the platform and the ocean floor gives the system room to move heavy blocks. That movement becomes the manga-friendly way to explain stored energy.
Solarjack says the ocean is not empty space. It is “two thousand feet of battery nobody put on the balance sheet.”
