In this paper a quasi-static electric generator is presented. The quasi-static nature consists in the fact that no solid moving part is envisaged, and the operating fluid remains contained within the device. More precisely, the generator is a Liquid-Metal MHD device, activated by a pressure vibration which causes the liquid metal to oscillate in a DC magnetic field, becoming seat of an electromotive force. The induced electromotive force causes an alternate current circulating in the liquid metal, which performs as the primary winding of a transformer, while a secondary coil, co axial with the current of the liquid metal, is connected to the electrical load. In the present paper, two different layouts of the device are compared, showing the differences in terms of efficiency.
