Wave energy to compressed air underwater storage to turbine generators rev 2

The second video of a similar idea, but now includes a better depiction of how the air is stored underwater.
Designed for the southern coastal populations of Australia. Including Perth, Adelaide, Melbourne and Hobart, and all smaller cities and towns in between.
Once Coal and Gas power generation are removed, we need to look at super green renewable energy sources. Given that our planet is covered by 78% ocean, it makes sense to utilize it for our energy source and energy storage. Wave energy along the southern coastline of Australia is as good as it gets. The northern coastlines of WA, NT and QLD, and the east coast of NSW do not have suitable regular waves to extract energy from. They do experience large tidal flow, which could also be used to power this system, but in a different way.
