As it was shown earlier, the Seebeck coefficient of some galvanic cells is higher than the predicted one by the equation (S₁ − S₂)/zF. We developed a model of converting heat energy into electrical energy based on the merger of the charged particles (micelles). It is shown that if initial electrical energy of two equal micelles is in the range of 35-50% of initial surface energy, then after the merger of micelles the increase in electrical energy comes out to be higher than the decrease in the surface energy. The additional energy was obtained because Brownian motion does a positive work against Coulomb forces. We pointed out that the additional entropy leaves the system with electromagnetic waves generated during the merger of micelles.
