An apparatus for extracting power from a fluid flow (110) comprises a fluid driveable engine (120), a conduit (140), disposed to enable fluid communication between a portion of the fluid flow (110), the fluid driveable engine (120) and a transmission fluid, the fluid in the fluid flow and the transmission fluid being different fluids and the portion of the fluid flow being at a lower pressure than the transmission fluid by virtue of its flow rate, thus causing the transmission fluid to be drawn through the conduit to become entrained in the fluid flow, the fluid driveable engine being arrange d such that the flow of the transmission fluid along the conduit acts to drive the fluid driveable engine (120).
