Schematic of a temperature controlled seawater basin. This design allows to grow/preserve coral species in secluded basins on the shore. As a huge number of coral species are in danger of becoming extinct in the next decades (especially in certain areas like the caribbean), this should prove helpful. Besides use in basins, the design could without a doubt also be used in public aquariums and aquatic theme parks. These, as well as the basins thus become, in effect, gene banks.

It should be noted that there is no roof over the basin, so sunlight can still come through. If need be, a transparent plastic could be placed over the basin to reduce the amount of sunlight that enters, and thus prevent the basin of becoming hot rapidly (reduces energy use of pump). The plastic then has to be placed over the basin in such a fashion that it does not work like a greenhouse (so leave a gap to allow air circulation and prevent buildup of hot air).
