Abstract

The present invention aims to utilise the properties of expansion and contraction of a fluid and in particular accelerated condensation of a vapour and provides useable energy based on these properties in the form of mechanical motion which can then be used to create an electrical output. There is provided a system for driving a turbine, the system comprising a conduit (5) and a chamber (2, 4), the conduit (6) defining a fluid flow path within which said turbine is located. The conduit (6) is in communication with an inlet to said chamber (2, 4). The system further comprises a piston (10) mounted in said chamber (2, 4) so as to define an enclosure (18) within said chamber and a heater for heating fluid within the enclosure. There is also provided means to move said piston (10) in a first direction (16) within said chamber (2,4) causing expansion of said enclosure (18), and heating means (8) for heating fluid within said enclosure (18) so as to cause expansion of said fluid into said enclosure (18). A condensing means (12) is also provided for condensing the fluid so as to cause contraction thereof and corresponding movement of said piston (10) in a second, opposite direction within said chamber (2, 4), thereby creating a suction force at said inlet of said chamber (2, 4) and drawing fluid through said conduit (6) and across said turbine.
