Abstract: an electric power generating station characterised by a solar array (1) source of electrical power connected to drive a compressor/condenser liquifier (9, 18) to condense compressed gas to liquid state and cryogenic temperature. The liquified gas is then evaporated in a finned heat exchanger (22) and the gas vapor is then conveyed to cool the compressor motor (9), a generator (55), and thereafter directed to the bottom of a liquid tower (41), subjacent a set of inverted buckets (49) spaced on an endless belt (50) engaged on pulleys (48, 52), all submerged in the tower liquid and one of which is engaged to drive the generator. As the buckets are turned around the upper pulley (52), the gas trapped therein is released and conveyed by a return line (45) back to the condensing-evaporation cycle. The use of a gas cycle liquified at cryogenic temperatures exposes the cooled motors (9, 32) and the cooled generator (55) to temperature at which superconductivity may be achieved.
