Patent ID: 7793652

Claim:
An apparatus for heating water in a contained environment comprising: a) a flotation means for buoyantly supporting said apparatus in a body of contained water; b) a reflective container member supported on said flotation means for substantially floating on a surface of said body of contained water, said reflective container member having a reflective inner wall for receiving a first solar energy directly from a sun and for reflecting said first solar energy to an interior of said reflective container member; c) a heat exchange member having an outer surface and an inner surface, said heat exchange member supported in said interior of said reflective container member for receiving a second solar energy directly from said sun on said outer surface and for receiving said first solar energy, reflected from said inner wall, on said outer surface; d) a dish reflector member supported in said reflective container member between said reflective container member and said heat exchange member, said dish reflector member for receiving a third solar energy directly from said sun and for reflecting said third solar energy on to said inner surface of said heat exchange member; e) a pump means connected to an input of said heat exchange member for pumping a water from said body of contained water into said heat exchange member via said input, said pump means supported submerged in said body of contained water; f) a photovoltaic power supply for driving said pump means; and g) a means for catching water located under the heat exchange means for catching water from an outlet means of the heat exchange member.
