<p>The present invention relates to a fluid pump assembly 10 comprising a tank 12 for holding a fluid 14 therein. The tank comprises an inlet 16 and an outlet 18. The fluid pump assembly further comprises a pipe 20 in fluid communication with the inlet and a fluid source 22, wherein said pipe is adapted to convey fluid from the fluid source into the tank via the fluid inlet, wherein the conveyance of fluid from the fluid source into the tank is actuated by a decrease in a first pressure value within the tank towards a second pressure value. Preferably solar radiation is used to increase the temperature and pressure within the tank during the day, while at night the pressure decreases to the second pressure value. A lens or a parabolic reflector may be used to concentrate the sunlight on to a heater component located on the tank.</p> |
