<p>A hydraulic drive system for powering a vehicle comprising: a fluid circuit; a battery driven motorised pump operable to circulate fluid around said fluid circuit; a turbine-generator operably associated with said fluid circuit to generate hydro electricity; and a drive motor for driving the vehicle connectable to the turbine-generator to be powered by the hydro electricity. The drive system may comprise an automatic switching system for enabling change over from charging of a first set of batteries and discharging of a second set of batteries to charging of the second set of batteries and discharging of the first set of batteries when the first set of batteries has charged above a predetermined level or the second set of batteries has discharged below a predetermined level.</p> |
