Stirling Generator
Cost-effective Solar Power Solution delivers flexible electricity and district heating/process heating continuously or on demand
Contemporary photovoltaic (PV) solutions are confined to harnessing the visible spectrum of light, neglecting the valuable ultraviolet (UV) and infrared spectra. The Stirling Generator surpasses these limitations by employing solar collectors that excel in capturing an impressive 92% of the sun’s energy as it reaches the Earth’s surface. This outperforms Concentrated Solar Power (CSP) systems, which typically capture up to 60%, and traditional PV solar farms, lagging behind at 16-22% efficiency.
What sets the Stirling Generator apart is its capacity to convert a broad range of heat sources, including solar, biomass, or waste heat. This versatility positions it as a suitable solution for both distributed and centralized energy systems across various scales and applications. Operating silently, emitting low pollution levels, and demanding minimal maintenance, the Stirling Generator emerges as an environmentally friendly and cost-effective choice. Its unique capability to deliver a consistent power output, even amidst fluctuating heat inputs, enhances grid stability and reliability.
Key attributes of the Stirling Generator include:
- High efficiency, producing 4.5 MWh per day in 1/3 of the space required by traditional solar solutions.
- Low environmental impact, ensuring constant power output and a long operational lifespan.
- Minimal maintenance requirements, making it suitable for off-grid applications.
- A cost of approximately $450,000 USD per MWh, reflecting a low entry cost and operational expenses.

How It Works
- We heat the material to 650C using thermal nano tech
- Heat is captured and concentrated on the tube circulating the transfer liquid
- The superheated liquid goes to the storage tanks
- One from the hot ones to the cold ones
- The liquid runs through the Stirling Generator, creating electricity, and discards a cooler “waste liquid”
- The waste liquid, still 300 degrees C, passes a heat transfer unit, sending out hot water or steam at the desired temperature, and returns the now further cooled liquid back to the heating system
Versatile Solution
Steam – Method
For businesses or locations already producing steam, the Stirling Generator provides the greatest benefits This system is 80% efficient. After increasing the heat, equipment is re-piped and steam is passed through the system and put right back where it started. The system is specially designed to direct steam so that all Generators receive the same amount of pressure at the exact same time.
Oil – Medium Storage
Molten Salt – 24 Hour System (Recommended)
- Residual Heat that provides a Thermal Battery
- Lasts 24 Hours up to 36 Hours (adding kit)
- The molten salt flows from the hot tank, through the Generator on demand, and electricity is made, then flows to the cold tank for heat exchange and reheating cycle of the salt melt
- The storage and conversion system can also work well with other sources of thermal energy including “waste” thermal energies – hot or cold
- Having thermal energy storage and electricity conversion abilities on boiler plants can optimize consistent fixed operations levels and even out the need for peak capacity in times of high consumer demand (peak times)

Superior Energy Capture
The Stirling Generator produces and stores thermal energy to deliver a combination of electrical and thermal energy at the LOWEST levelized cost of any renewable energy source with storage. The system delivers clean, green energy during the day and throughout the night.
- The system’s energy capture arrays harvest up to 92% of the solar irradiation hitting the earth
- 70% more efficient than standard Photovoltaic (PV) Solar Panels
- 32% more efficient than Concentrated Solar Power (CSP)
The Energy System can form a significant part of the “missing link” in the green transition. Due to the sizable and cost-effective energy storage capacity, and the ability to store energy for days with minimal losses, the system enables an even energy output profile 24/7.
- Contributes massively to carbon emission reduction targets
- Reduces dependency on fossil fuels for generating electricity
- Reduces carbon footprint and GHG emissions while driving consumer prices down
