Abstract:
1. A power generation system comprising: a heat source provided at a first location; a heat sink provided at a second location, wherein said second location is elevated relative to said first location; first fluid communication means extending from said heat sink to said heat source; a power transfer system in fluid communication with said heat sink; and second fluid communication means extending from said heat source to said power transfer system, wherein said fluid communication means are operable to circulate a thermally expandable fluid in a loop between said first and second locations, said fluid circulated from said first location, where it is heated and expanded by said heat source, in an upwards direction through said second fluid communication means to said second location, where it passes through said power transfer system and is cooled and contracted by said heat sink, and in a downwards direction through said first fluid communication means back to said first location, the circulation of said fluid operable to drive said power transfer system to generate power, characterised in that said power generation system further comprises a pressure regulation means wherein said regulation means is operable to regulate a pressure difference experienced by the fluid at said power transfer system to prevent said fluid flashing to a vapour.
