Solar farm in Australia could power Singapore via 4,500km undersea cable

Sharks love biting cable with electricity flowing in it. Even with redundancy, submarine cable cuts cause big outages on the internet, I am sure they know this but I wonder why they think the risk is not a deal breaker?

You know what would be cool? Robots/Drones that dig trenches in the ocean floor and bury the cables! But even to lay them down like it is done now, it is very expensive with only about a dozen or so cable ships in the world I believe.

It’s not a deal breaker because there are many underwater HVDC cables in operation across the world that have been reliability operating for years or decades.

If sharks (or other active water hazards) are a concern, you bury the cable with water jets below the sea floor.
