Just a solution without fuel generation at mini-HPP! No river, stream, or waterfall. This solution was found by chance, based on academic knowledge. Industrial HPP on this effect can not be built, the forces of nature unfortunately can not be modeled on a large scale, it is easier to use, which is what they do when building dams for HPP. In addition to industrial, there is a class of small stations, up to mini-hydroelectric power plants up to 3 kW. They need a difference in the height of the discharged water. Is it possible to have a hydraulic drive without a height difference? Having come across an interesting point in the textbook of academic physics, the possibility of creating such a drive was worked out and calculated. Surprisingly, all components for the build are released. The material calculates and offers an option for two paired car generators with a total output power of 4 kW. To the book in PDF format, there is a book in Excel format, with two calculation options, mini-hydroelectric closed type or from the discharged water. You can choose and calculate everything for yourself, just insert the source data into the table and evaluate the possibilities. A description and method for calculating the axial generator based on the Gramme generator, where the magnetic induction vector of the magnet poles and the induced field by the phase coils are perpendicular to the induction EMF guidance loss. The material adds a variant for calculating the design and selection of the Pump, turbine and Nozzle available on sale, output power 10-20 kW.
