Hydraulic Motor alternate cylinder cavity conical feedback
"The boundless energy is not a dream. It is the next logical step for mankind."
Rafael Serrano
It is not an absurd perpetual engine!
It is a ultra-efficient system which is characterised by reuse The hydraulic fluid in a cylinder does not change state, however, and can be reused in the same package indefinitely until its life cycle is exhausted. However, the hydraulic fluid in a cylinder does not change state and the same package can be reused indefinitely until its life cycle is exhausted.
In this way, by devising a system that prevents most of the hydraulic fluid from leaving the enclosure where it acts, it is possible not to have to evacuate all of the hydraulic fluid after it has completed its delivery cycle. The consequence is that in the end only one 0.84% of new impeller liquid in each cycle with respect to a standard cylinder according to the (non-limiting) model shown here as an example. This makes it possible that the pump driving it can be 9.16 times less powerful than that required to actuate a hydraulic cylinder equivalent in diameter, height and stroke of its piston and therefore feedback is physically possible, by obtaining for practical purposes a complete filling of the chamber intended for the impulsion although it actually only a portion is injected of the same in each cycle.
This is why "this project is so revolutionary that it challenges the status quo. The data provided on this web site show that generate massive energy and almost free is technically feasible, but we are aware of that no one has tried before to this scale and we are also aware of the fact that the initial skepticism is inevitable, as happened with the electricity, or more closely with the internet.
Investing in the unknown requires courage, but the calculations-available here publicly - don't lie: if you hit, we will change the energy future of humanity. If we are wrong, we will have ruled out a critical path with rigor and transparency.
The risk is not to ignore this opportunity, is to not give it a try.«
Therefore, as the Wright brothers in front of the aviation, we know that the first attempts to cast doubt, but the numbers -not the optimism - force us to try.
In final phase of construction
One 30% short of completion

Extreme efficiency
We have solved the problem of friction losses in hydraulic systems. Our prototype is capable of backfeeding at 400 bar, validated by CFD simulations, but the remaining 30% is still to be completed to conclude this stage.
In addition to the hydraulic fluid savings provided by a coniform cavity, two other methods of saving hydraulic fluid further reduce the need for driving fluid, resulting in the use of less than 10% of the volume required by any standard hydraulic cylinder of the same power.
This means that this engine has:
Capacity feedback
Ruled by the formula E = PhAThis engine offers great power and feedback capability.
E: potential energy; P: applied pressure; h: race; To: area of the base

Revolutionary Sustainability: Zero Emissions, Maximum Efficiency
This hydraulic system represents a key progress in industrial decarbonisationby completely eliminating combustion and its polluting emissions. Its optimised design reduces environmental impact in three pillars:
✅ Clean energy 100%:
🔹 Works exclusively with hydraulic fluid in closed circuit (0 direct emissions).
🔹 Compatible with renewable energies (wind, solar) to power the pressure pump.
✅ Circular fluid economy:
🔹 100% reuse of the liquid in each cycle, no leakage losses (certified hermetic seal).
🔹 Reduces fluid consumption by up to 90% compared to traditional systems (less chemical waste).
✅ Radical efficiency:
9x less energy required for equal power than electric or heat engines (Alpha prototype test).
🔹 Long-life materials (service life ≥20 years), reducing industrial waste.
Key innovations
Conical rather than cylindrical cavity
Imagine an engine that uses water pressure (like a hose at full power) to move a piston. Since the volume of a cone is smaller than that of a cylinder, it needs less fluid and less energy to generate the same force:
🔹 Volume of a right cone = ⅓ of the volume of a cylinder (same base and height).
🔹 Formula: Vcone = (1/3) πr²h - - - Vcylinder = πr²h.
Technical operation (current model)
Power Stage (Injection at 400 bar)
✅ A hydraulic pump injects fluid at 400 bar in the conical cavity, shifting the larger base (movable piston) axially.
Constant pressure translates into linear force: F = 400 bar x Piston area.
✅ The conical geometry reduces a 66% the required fluid volume vs. a traditional cylinder for equal force.
Return Phase (Discharge + Crankshaft)
When the top dead centre (zenith) is reached, a relief valve opens, releasing some of the fluid.
✅ A crankshaft mechanism returns the piston to its initial position, completing the cycle.
Constant Pressure = Higher Efficiency
✅ The 400 bar remain stable The system is designed to prevent fluctuation losses (typical in piston-cylinder engines) over the entire stroke.
✅ Reduced volume (⅓ of a cylinder) → Less fluid for equal work → Smaller pump and lower energy consumption.
Fast Cycle + Low Maintenance
Simplified sealing at the fixed apex (only 1 critical joint vs. traditional systems).
Convergent flow (base → apex) reduces turbulence and wear.
