Vis a Vis reports: Innovative islands of French Polynesia


Somewhere in the big blue ocean, there lies an island that can serve as a blueprint for the approach to tackle the challenges of climate change with a self-sufficient supply through renewable energies.

We are currently in the South Pacific in one of the most isolated hotels in the world. Island Resort Tahaa on French Polynesia is powered by the sun. Sun generates energy and sends out to Earth that technology like solar panels transforms into electricity. 

The solar energy produced is not only able to power our resort, but it is also critical to stimulating a vibrant and healthy reef surrounding the island.

The concept of so-called Biorock involves applying a low voltage electrical current, completely safe for humans and marine life, to a submerged conductive structure that causes dissolved mineral crystals in seawater. Biorock is most of all powered by renewable energy through photovoltaic solar panels. The composite is made of limestone, calcium and brucite, magnesium with mechanical strength similar to concrete and which makes it a natural composition of coral reefs and tropical sand beaches. 

Biorock methods speed up coral growth in damaged areas and restore the authentic coral reef organisms. Diving through it, I got to see the full range of species and local biodiversity. This original solution of an architect and Marine scientist, prof. Wolf Hilbertz was being developed from 1974 for 15 years and from 1988 is licensed for use of the Tahaa resorts. Thank to such innovations, Polynesian’s coral reefs are considered the world’s healthiest and are vastly growing.
