APWEC
Atmospheric Pressure Wind Energy Collector — the Italian renewable energy generator that uses fluid-air depression, producing electricity continuously.
Clean energy from the atmosphere
The system generates a controlled internal airflow that reaches high speeds and drives a rotor connected to the alternator.
Built for decades of continuous and reliable energy production
Modular components designed to operate in closed or open environments, both civil and industrial. Certified reliability, low maintenance, ground-level access, maximum energy output.
Operational in less than 48 hours: renewable energy that integrates into your plant
Ground-level installation, indoor or outdoor operation, on/off at will, no need for natural wind or complex/tall structures to capture wind at height.
The Italian technology based on high-velocity fluid and atmospheric depression
APWEC is a system that uses fluid-air to generate continuous electrical energy. The internal airflow is accelerated and controlled to drive a rotor connected to a generator. A technology born from a dream pursued for decades: to demonstrate that it is possible to produce energy uninterruptedly without depending on fossil sources, such as wind, sun, tides or others.
Unlike traditional renewable energy generation systems, APWEC does not depend directly on solar irradiation or meteorological variables, and can operate practically without interruption throughout the year. Real energy savings, zero emissions, independence from the electrical grid.
Continuous Operation
Up to 8,660 annual hours
Constant energy production independent of weather conditions.
Scalability
From 1 kW to approx. 10 MW
APWEC's modular architecture allows the plant to be sized according to the user's real energy needs.
Maintenance
Simple and safe
Ground-level access, no work at height.
How APWEC® works: three sections we have named vessels
The APWEC® generator is composed of three vessels solidly fixed to one another. The first generates airflow with openings for atmospheric air intake. In the second vessel there are a series of annular Induction Chambers (I.C.) appropriately designed to accelerate the flow within this second section. The third converts the considerably accelerated high-speed airflow kinetically into electrical energy via a rotor connected to the alternator.
First Section
Flow generation and amplification
A high-speed trigger jet enters the first annular Induction Chamber. The pressure difference generated according to Bernoulli's Principle draws atmospheric air from outside, progressively amplifying the airflow at each successive I.C. The casing material can be steel, aluminium or reinforced plastic for maximum construction flexibility and cost reduction.
Second Section
Conversion into electrical energy
Since the system operates in a duct and the flow is always unidirectional with the same airflow speed intensity, the APWEC rotor does not need a variable-pitch blade system, since the airflow speed always remains the same.
Technical and economic advantages over the state of the art
The basic concept is Simplicity. Simplicity of calculation, construction and operation. The comparison between APWEC® and large conventional wind turbines highlights structural advantages that impact construction, maintenance, installation and operating costs. APWEC, a next-generation generator designed according to the automotive construction philosophy.
Operability
Operation up to 8,660 annual hours
Continuous energy production independent of weather conditions. No dependence on wind or solar irradiation: the system operates 24/7 for the entire solar year, with scheduled stoppages for maintenance only.
Maintenance safety
Ground-level maintenance, no work at height
All service operations take place on the ground. No intervention at significant heights, eliminating the operational risks typical of conventional wind turbines that require specialised technicians working at height.
Construction simplicity
Fewer components, automotive-style construction
APWEC® requires fewer parts compared to the state of the art. The automotive-derived construction philosophy guarantees standardisation, global availability of components and reduced production costs in large series.
Fixed-pitch blades
No variable pitch mechanism
The internal airflow is unidirectional and controlled. The rotor blades operate at fixed pitch, eliminating the variable pitch control system: one of the main sources of failure and cost in large wind turbines.
Installation flexibility
Indoor and outdoor operation, adjacent to the user
APWEC® can be installed inside industrial buildings or outdoors, without the need for towers or elevated structures. Installation adjacent to the end user reduces transmission losses and grid connection costs.
Analogy with industrial turbines
Structure derived from the industrial gas turbine
The physical configuration of APWEC® follows the structure of industrial gas turbines, themselves derived from jet aircraft turbines. A mature, reliable technology with decades of engineering know-how behind it.
Large wind turbines exclusively exploit the dynamic pressure of external wind and require minimum wind speed, tall towers, variable pitch mechanisms and maintenance at height. APWEC® operates with a controlled internal flow, at ground level, regardless of external atmospheric conditions — a technically distinct and complementary category in the landscape of distributed renewable energy generation.
