CONCEPT FOR A WORLD WIDE ELECTRICAL GRID
It is time to start a world wide electrical grid. A feasibility study needs to be started now. The technology exists to build a world wide electrical grid now. The power would be transmitted with direct current to minimize losses from converting DC to AC. Direct current is now transmitted many miles on land and in the sea. Solar and wind power would be available 24/7 because there’s always wind and sunshine somewhere on earth. Solar powered homes could be on this grid, too. And the grid would be it's own "battery."
The transformers could be located on land. Sometimes, on islands. This could all be worked out. Also, transformers could be designed to be submerged in the sea.
This concept is doable.
