South Africans have invented an electromagnetic shield that protects humans from shark attacks. The idea has already been tested and saved lives.
The technology is based on a three-dimensional electrical waveform that induces spasms in the sharks’ snouts, saving surfers and swimmers from severe injuries and deaths.
After the series of attacks at the Egyptian Red Sea resort of Sharm el-Sheikh, the local authorities have shown interest in buying devices to protect the tourists.
The shark shield does not interfere with the movement of ships and boats and can be safely used by anyone.
There's even a special device for surfers.
It's a compact, lightweight unit designed specifically to be mounted on watercraft, including surfboards and windsurf boards.
