The technology of our generator
The Generator of the Future
The Technology Behind Our Generator
STG has designed and built the first prototype of a power generator that converts mechanical energy into electrical energy, more efficient than models currently on the market, thanks to patented free-moving pistons and a simple construction without a flywheel.
The direct injection of biogas, hydrogen, or other fuels into the engine, combined with adjustable dynamic compression, allows for even better performance compared to turbocharged solutions.
The STG power generator consists of 4 combustion chambers connected through 2 independent rods that house exclusively designed linear generators.
This simple configuration avoids unnecessary movement conversions (linear to rotational) while allowing the two pairs of free-moving pistons to have synchronized opposing motion with programmable compression.
The result is a high-power output with further reduction in vibrations and noise.
Complete technical documentation and construction CAD drawings are available upon request.
Below are some technical features and comparisons, extracted from the conclusions of the technical team.
The STG energy generator can be developed with different power levels and sizes for various applications. See the chapter “Applications.”

Technical Comparisons
As evident, our generator has no competitors because no generators on the market are built with our highly innovative and revolutionary technology.
When comparing power and efficiency, the strength of the STG Linear Generator lies in its efficiency, over 50% higher than that of its competitors.
Regarding consumption, the best performer is the STG Linear Generator, which is the most advantageous in terms of kg/kWh due to its lower consumption compared to competitors.
The consumption per m³/kWh or kg/kWh of current generators is almost double that of an STG generator.
A weight comparison highlights the extreme lightness of the STG generator.
A volume comparison shows that the STG generator occupies significantly less space, allowing for installation in confined areas.
Regarding dimensions, the height of the STG generator varies between 20 and 30 cm, enabling its use in various sectors where other generators cannot be installed.
As noted by AVL, the hallmark of this technology is its simple construction, consisting of fewer than 100 components, with only a few moving parts, compared to the more than 2,000 components—many of them moving—found in current generators on the market.
Additionally, the STG generator can be applied in scenarios requiring very low noise and vibration levels.
Conclusions
The technical data obtained so far already demonstrate the great potential of our generator in its various models and in comparison to current market generators.
The design data is based on further development of the potential of linear generators.
Our generator, with its groundbreaking innovation, will revolutionize the generator market for many years to come.
