Many islands around the world are facing the risk of being flooded in the near future.
FloatIfy project manager Jeb “Flipper” Fischer: We collaborate with drillers and miners who will bore the islands free from the seabed. Then we will attach a bunch of air tanks to the underside of the island, easy as pie! With a few jet engines, the islanders can move around and anchor up anywhere. We are in a serious discussion with Taiwan right now, and hope to free the island starting next year. We are planning to anchor it next to Hawaii.
