Abstract
A magnetohydrodynamic (MHD) device including an electrochemical cell, an aqueous liquid, and a magnet is provided. The electrochemical cell includes a first and a second electrode and an enclosed gas volume fluidly connecting the two electrodes. The first electrode generates a reaction gas at a first rate, the second electrode consumes the reaction gas at a second rate, the first rate being substantially equal to the second rate. The aqueous liquid is between the first electrode and the second electrode and includes a current having a direction. The magnet generates a magnetic field having a direction normal to the direction of the current. The MHD device produces a propulsive force having a direction simultaneously normal to the direction of the magnetic field and the direction of the current.
