Wolf Hibertz wants to use the oceans as a future site for homes. The visionary designer has found a way to use sunlight to turn minerals in seawater into limestone. The limestone would be used to construct floating island homes.
Autopia Ampere would begin as a series of wire-mesh armatures anchored on top a sea mountain. After it is place, they will be connected to a low-voltage direct current supplied by solar panels. Electrochemical reactions will draw minerals from the sea to the armatures over time to create walls of calcium carbonate - which is also called limestone. In the same way that a sponge absorbs water, oceans absorb CO2. By removing carbon-containing compounds from the oceans, the mineral accretion could reduce the further buildup of carbon dioxide, thus reducing greenhouse gases.
Hilbertz plans to grow a self-sustaining island island city on Seamount Ampere, which is situated between Madeira Islands and the tip of Portugal. If constructed ,it will extend 50 feet down to the bottom of the Atlantic.
