electrolytes in the saline liquid react with magnesium and copper plates on the interior of the lamp to produce electricity.

a specially designed electronic circuit that manages to extend the transfer of ions from a saline medium to convert them into useful and immediate energy. The electrodes of the salt bridge make it possible to drain energy from the salt water, (a known process), but with the electronic circuit with which it is possible to extract around 500 watts for each liter of water.
