Starting from the operating principle of so-called ram pumps Dr V. Marukhin and his co-workers have developed various types of self-running generators which are based on autonomous hydraulic oscillations. An example is shown in the picture and sketch on the left which were copied from Figure 19 of a paper by Dr. V. Marukhin and Dr. V. Ivanov.
In the sketch above the blue color represents a liquid such as water and the white space above is filled with a gas such as nitrogen. Both the liquid and the gas are put under a high pressure of up to 3000 bar depending on the design or type of the generator. To initiate the self-running (undamped) vertical fluid and gas oscillations it is necessary to apply a specific high pressure pulse for a short time. That is realized by an electrically ignited explosion of about 2 g gun powder. The resulting pressure wave is transferred into the generator via a shock valve. The frequency of the self-running (undamped) vertical fluid and gas oscillations can be up to 3000 Hz depending on the design or type of the generator. The self-running hydraulic oscillations are converted into a pulsed high DC voltage by piezoelctric transducers. The pulsed DC voltage can be up to 12 kV depending on the design or type of the generator. Via a DC / DC and DC / AC converter a convenient form of electricity can be obtained. The resulting usable output power can be up to 1 MW depending on the design or type of the generator. The following and already above-mentoned paper by Dr. V. Marukhin and Dr. V. Ivanov reports about a 125 kW generator which worked non-stop for 2 years, connected to different loads and at different ambient temperatures: https://novam-research.com/resources/Generators-based-on-self-running-hydraulic-oscillations_Paper-by-V-Marukhin-and-V-Ivanov.pdf
Slide set (67 pages, 3 MB pdf, mainly in German) of a German-language talk by Adolf Schneider from October 2025 about ram pumps and self-running generators based on autonomous undamped hydraulic oscillations. His talk took place on 12 October 2025 in Germany at a German-language congress about novel energy technologies and related topics.
A German-language report about that congress is published on pages 4 - 21 in the November / December 2025 issue of the German-language journal NET-Journal (ISSN 1420-9292). It comprises on pages 18 and 19 the German-language sub-report "Revolutionärer hydraulisch-elektrischer Generator bis 1 MW" about the generators developed by Dr. V. Marukhin and his co-workers.
The following table from page 44 of the slide set from Adolf Schneider displays an overview of the self-running generators which are based on autonomous undamped hydraulic oscillations which were developed by Dr V. Marukhin and his co-workers (as of August 2025) (there and in the slide set from Adolf Schneider the generators are called HEG which stands for Hydraulic Energy Generator and "HEG-Typ" means HEG type):
The generator types EGMHS-2000-25 and EGMHR-750 can be delivered with an associated DC / DC and DC / AC converter which provide a stable output voltage of 3500 V DC and 220 V AC, respectively (as of August 2025).
The generators are not marketed publicly. As of August 2025: According to Dr. V. Marukhin there are 23 generators in operation at undisclosed industrial customers in the following countries: Spain, Portugal, Morocco, Saudi Arabia, United Arabic Emirates, Madagascar, China, and Russia. In Spain there is a holding company of Dr. V. Marukhin and his co-workers which comprises also a manufacturing site. There only shareholders of the holding company can order generators. The manufacturing of the generators takes also place in some of the other above-mentioned countries on behalf of the corresponding license partner. The latter is authorized to manufacture generators only for its own use. The production time in Spain is 1 month, in China 4 months, and in Russia 6 - 8 months.
It is intended to acquire for some countries a license for the most recent version of the 1 MW generators and make for Switzerland, Germany, and Austria some demonstration generators available which can be viewed and inspected on request. However, the implementation of this intention is impeded because of the imposed sanctions against Russia. Therefore the desired demonstration generators can be available earliest in 2026 or 2027.
About the operation principle of these self-running generators which are based on autonomous undamped hydraulic oscillations
The russian inventors Dr. V. V. Marukhin and V. A. Koutienkov have developed a macroscopic theory which comprises about 500 formulas (fluid mechanics, fluid dynamics, hydrodynamics, hydraulics etc.). It allows the design of a new type of ram pumps without water losses. Under specific geometrical and dynamic conditions these systems work autonomously.
Microscopic perspective (general description without knowing the involved detailed processes): The author of this website assumes that this and any other self-running energy technology extracts usable energy from an everywhere present form of energy which is called space energy, vacuum energy, zero-point energy, or ether energy as described in this information document . The tapping of this form of energy happens probably via the earth`s gravitational field which acts on the water and gas molecules and / or via electromagnetic fields that act at the atomic level between the water and gas molecules and / or via the electromagnetic fields that act at the atomic level between the atoms of solid materials and the water and gas molecules.
