How are Biorock reefs powered?

To power the mineral accretion process, a low DC voltage is necessary. The source of this current generally depends upon the environment near the reef. If a ready supply of electricity is available, cables can be attached to the structure. In more remote areas, solar collectors are usually the energy source. These panels will generally be set up on the shore to feed current to the Biorock reef via submerged cables. Power can also be supplied by other non-polluting sources such as windmills or tidal current generators.

In practice, a low voltage direct current is fed to the reef via cables. The structure acts as a cathode. A special inert material is used as the anode to complete the electrical circuit. The low power is completely safe for swimmers and marine life.
