The system comprises a central shaft located on enclosed bearings at either end of the shaft. A turbine wheel (6) is keyed to the shaft (8) with turbine vanes designed to maximise the force of the fluid flowing over the vanes thus causing optimum rotation of the turbine wheel and connected shaft. A fixed guide vane unit (7) is held in place by a separate fixed member. The vanes are designed so that they guide the fluid smoothly into the moving vanes of the turbine wheel without shock. A gate unit (9) with opposed openings is supported by a central boss keyed to the shaft so that the gate unit rotates in phase with the turbine wheel by admission of fluid through the openings and into the fixed vane unit and finally into the rotating turbine wheel. A casing (3) surrounds the gate unit, fixed guide vane unit and turbine wheel unit. A scoop inlet duct unit (2) of inlet size admits and directs the required flow of fluid and is truncated and flanged for coupling to other components of the system.    A base unit is flanged and ribbed for strength and designed to support the assembled components of the system with bolt hold flanged for grouting purposes. The scoop inlet duct unit is fitted with heat supply unit where required to improve power generation performance. The shaft is fitted with flywheel if required for speed control of the turbine wheel. A suitable generator (5) is coupled to the shaft with a unit to match required power output in phase with the speed of the turbine wheel unit. An alternative compact generator of size conveniently fits into the annular space around the shaft. Electronic or other controls interface match control of the system and its generator and battery system or motor fitted to any vehicle or on a static platform.    USE/ADVANTAGE -   For generation of electricity from ram effect of air or water flowing in system which is either static or on moving vehicle such or car, rail vehicle, ship or aircraft. Generator power cleanly and cheaply, to replace power by conventional power or transport systems which heavily pollute atmosphere and are costly to mfr. and generate high cost power.
