A device capable of translational movement has a base capable of movement across a ground surface or across or through a liquid surface. The base mounts one or more wind turbines aligned substantially horizontally in use, and a drive element operable to move the base. The drive element is powered directly or indirectly by the turbine or turbines. The turbine(s) are such that the turbine operates over at least a wide range of wind directions relative to the device. In the preferred form the turbines are spaced outwardly from the base so as to provide a vehicle space between the turbine or turbines and the base.
