Abstract: A LMMHD power generation cell, having a fluid channel in which a conductive fluid is forced to flow in response to an external force. A pair of pressure conveying members such as bellow reservoirs can be used for conveying the external force to the conductive flow. A magnetic field is established across the fluid channel by a pair of magnets. A pair of electrodes is disposed with respect to the fluid channel to collect the electric current induced by the conductive fluid flowing through the magnetic field. The magnets are selected from either permanent magnets or electromagnets. Preferably, the conductive fluid is selected from low-density, low-viscosity, high-conductivity liquid metal such as NaK-78.
