NOVELTY - The ribbon drive power generation apparatus has at least one ribbon (61) which is located entirely within a containment tube (62) in a longitudinal direction. The ribbon is formed of coils that helically extend from the first end to the second end of the tube. The frequency of coils per unit length of the tube increases from the first end to the second end of the tube. A power drawing mechanism obtains power from rotation of the ribbon so as to generate power from fluid moving from the first end to the second end of the tube.    USE - Ribbon drive power generation apparatus used with hydrokinetc systems to extract fluid energy in e.g. rivers or streams, bay currents, ocean currents, dams, marinas to produce electricity for e.g. vessels docked or moored or at sea summer homes, camping sites near flowing water, remote monitoring for meteorological or military or pipeline observational and other reporting purposes, emergency power for vessels stranded underwater or otherwise rendered motionless, downspouts, water fountains, shower heads, cardiovascular installation in a living being to provide electric current for various internal applications, milking machines, manufacturing processes using moving or recirculating fluids, pumping water into oil wells to reclaim more oil or fill voids, rooftop water towers, downpipes, replacement or supplementation of pressure relief valves inside water systems of multilevel buildings, miniaturized micro circuitry. Can also be used to bleed very small amounts of energy from existing fluid systems to provide small amounts of electricity that are typically provided by sources such as batteries to power e.g. flow rate monitors, shower stall, fans or radios, lighting displays for public water fountains.    ADVANTAGE - Can be employed in a variety of sizes based on the particular space or configuration restrictions of area or areas in which it would be employed, and can also be employed in a variety of teaming arrangements in pairs, threes, fours, and so forth as well as in parallel or series based on the specific requirements of a particular installation, thus achieving flexibility which allows power generation efforts to be employed in situations not ordinarily considered for power generation. Allows use of magnetic clutch to eliminate having a continuous shaft directly from the end of the rotating ribbon or coil to a gear reduction mechanism associated with alternator/generator, thus avoiding the need to use a tight bearing assembly to prevent fluid leakage into alternator/generator housing that is directly in line with the ribbon or coil assembly. Allows the number of magnets in each half of the magnetic clutch to be adjusted so that when the revolution per minute or torque of the clutch reaches a certain level, the clutch will begin to slip, thus preventing the alternator/generator from over-reviving beyond a predetermined rotational or torque limit that would potentially damage the reduction gears, bearings, or belts, or the alternator/generator, whether by overheating or by premature wear of the bearings in the alternator/generator. Eliminates friction and the mass or inertia of other types of connections between alternator/generator and the ribbon or coil rotating mechanism. Provides a reduction gearing mechanism which allows for easy adaptation of the ribbon or coil to different rates of fluid or water flow or different water head at various sites or installations in order to match a desired performance curve, by enabling the relatively simple substitution of one set of gears with other sets.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a ribbon drive power generation method. The power drawing mechanism is selected from a group consisting of stator field windings, rotating magnets, a power take-off pulley surface on the exterior of the tube, and a power take-off gear surface on the exterior of the tube.
