LETTER FROM LOMBOK
by Barbara Lucas Cahyadi

A couple of issues ago, I wrote about the problems of tackling rubbish on developing islands in Indonesia. Although to some it may be an insurmountable problem or even “someone else’s problem”, to Delphine Robbe and the Gili Eco Trust it is their problem and they are doing something about it!

The Biorock® method was invented, developed, and patented by the late Prof. Wolf Hilbertz and Dr. Thomas J. Goreau. The Biorock® technology uses low voltage direct currents (above 1.2 Volts) going through a steel structure. The Biorock® process also called electrolysis is happening between 2 metals receiving electricity in sea water, resulting in a steel structure to grow solid limestone minerals and the other metal to slowly disintegrate. These currents are safe to humans and all marine organisms.
