As The United States of America fleets surround the islands, and install the holes around and through the bottom of the islands, a simple concrete or built structure along the bottom below the holes with flotation above from the Air dynamos keeping the island up, we can make all islands on the planet mobile. The United States of America could be one the first countries that sell the service to countries. All island nations would become their own unique countries, increasing life on Earth.
Advent Guard Note: We should build our ocean energy capture points at the lowest point around The United States of America once we can speed up moon moon and produce more power so the countries of Earth do not completely wipe out ocean life by eating up all current energy and stopping it. Though keeping it a lower energy would be possible now, we research onto impact. So in the future as Earth grows, we could re-arrange the countries in anyway.
