Further installations will likely be overseas, Andreotti said. The team is in touch with countries including New Caledonia, Réunion, Australia, Mexico, Brazil, Egypt and Dubai. “But what makes Mike special is that he took the extra step of envisioning a fake forest of kelp to replace the shark nets. At the end of 2011, an American scientist Rutzen and Andreotti presented their draft to O’Connell and offered to work together. The concept was registered in 2012 as a patent through Stellenbosch University’s technology transfer company, Innovus, and commercialised two years later.
Using this knowledge, the developers created a strong magnetic field by inserting magnets into the kelp-like pipes. However, instead of attracting the attention of a shark, the overly strong magnetic field over stimulates the Ampullae of Lorenzini and acts as another repellent. By inserting strong magnets into the kelp-like pipes of the barrier, it further strengthens the ability of the design to repel sharks, Andreotti said.
