Apparatus (10) for use as a motor or generator, comprising: a first part (20) defining a first region (22);a second part (40) moveable relative to the first part (20) and spaced therefrom to form a fluid-filled gap (50), the second part (40) defining a second region(42) separated from the first region (22) by the fluid-filled gap (50) and configured to be electrically connected to the first region (22) during at least one mode of operation; wherein the apparatus (10) is configured to form an electrically conductive path between the first and second regions (22, 42) by generating a region of electrically conductive fluid in the fluid- filled gap (50) between the first and second regions(22, 42). |
