Полезная модель относится к области производства электрической энергии и служит для преобразования энергии русловых потоков ручьёв и малых рек в электрическую энергию с помощью явления электромагнитной индукции.Детали гидротурбины и полый усечённый конус изготовлены из полимерного композиционного материала, например углепластика. Понтоном служит древесина, прочный пенопласт или герметичный контейнер для деталей и узлов переносной микроГЭС, якорный шест нержавеющий.После выбора подходящего места в русле ручья или реки забивают в дно якорный шест, устраивают понтон с электрическим генератором, соединяют гибким валом вал ротора генератора с гидротурбиной и полым усечённым конусом. Полый усечённый конус создает дополнительное сопротивление прохождению естественного потока воды, а за счёт лопастей турбины, изогнутых по конической винтовой линии, приходит во вращение.

An generator/motor that initially uses external power to spin a partially submerged low drag fluid distributor rotor that uses centrifugal force to cause fluid to flow from the center of rotation, through a plurality of Euler curved penstocks, allowing the fluid to flow in a true radial direction through a high “g” artificial gravity field, which dramatically increases the fluid's kinetic energy and released available power (Pa), before it is guided out tangentially from the distributor via a plurality of nozzles symmetrically located at a small height just above the reservoir surface (near zero lift). As the frequency of the rotor is increased linearly the fuel artificial gravity increases exponentially, as does the fluid dynamic available power (Pa). Turbine runners on the rotor assembly capture the available power (Pa), and a positive feedback mechanical transmission couples the captured rotational power to the I/O shaft in its initialized direction thus replacing the external power with internal fluid dynamic derived mechanical power to sustain rotator rotation and drive the shaft of an electric generator. 1.
