Heavy high-temperature industry
Steel, glass, cement, chemicals, refining: continuous thermal flows above 600 °C, sometimes 1,000 °C, captured directly on process lines.
Turn a structural loss into a measurable, controllable output.
Star HarvestingTechnologies
The world isn’t short onenergy. It wastes it.
We capture industrial waste heat above 600 °C and convert it directly into mechanical power, electricity and compressed air. No combustion. No fuel. No external dependency.

ACT I — THE ORIGIN
All energy comes from a star
150 million kilometers away, the Sun releases every second the equivalent of millions of nuclear bombs as heat and light.
That heat is the matrix of every form of energy available on Earth. Without it, no wind, no rain, no life, no carbon, no oil, no industry.
Everything starts as a thermal flow. Everything still depends on it.
ACT II — THE EARTH
A planet that receives, transforms, accumulates
Earth absorbs a tiny fraction of this solar output — yet it is enough to drive oceans, winds and seasons.
That same energy, captured by the living world over hundreds of millions of years, hides today in every ton of coal, every barrel of oil, every cubic meter of gas.
We don’t live in an energy-poor world. We live in a world that never learned how to keep its energy.
ACT III — THE LIVING
Plants, the first solar engineers
For hundreds of millions of years, forests, giant ferns and phytoplankton captured sunlight and stored it as organic carbon.
It was the very first large-scale solar harvesting system — silent, distributed, free.
This vegetal memory is the invisible energy bedrock of our entire industrial civilization.
ACT IV — THE FOSSIL
When life turns into fuel
Buried, compressed, heated for millions of years, that biomass became oil, gas and coal.
Solar energy concentrated to the extreme — dense, transportable, addictive.
The trap was to believe it was infinite. The real waste isn’t having used it. It’s dissipating it today without harvesting its value.
ACT V — INDUSTRIAL FIRE
Above 600 °C: paid for, mastered… then lost
Steel, cement, glass, chemicals, refining, stationary engines, marine propulsion, high-temperature fuel cells: industrial fire produces dense, steady heat well above 600 °C.
That heat is generated, paid for and controlled — then released into the atmosphere.
More than 60% of the world’s primary energy is dissipated as heat. That’s exactly where our story begins.
ACT VI — THE HARVEST
Star Harvesting: capture, convert, return
Our high-speed thermal-exchange engines operate above 600 °C, plugged directly into existing industrial processes.
They convert waste heat into mechanical power, electricity or compressed air. No extra combustion. No fuel. No external energy.
Heat stops being a waste product. It becomes the engine itself.
AMBITION
Halve emissions linked to thermal waste within ten years
By raising existing equipment efficiency by 40 to 60% through heat recycling, we massively reduce primary energy needs.
Less fuel. Less imported electricity. Fewer emissions. If energy is used twice, emissions can be cut in half.
It is not an ideological promise. It is a physical consequence.

CAPITALISM × ECOLOGY
A false opposition, dissolved by physics
For decades we’ve been told economic performance and environmental responsibility are opposites. Our technology dissolves that opposition.
The more an industry cuts emissions, the more profitable it becomes. We don’t ask industrials to make a sacrifice. We hand them a strategic advantage.
Less waste = more value
Less CO₂ = lower costs
More efficiency = more competitiveness
Green investment = economic return
BLUE ECONOMY
Our philosophical framework
Our approach is fully aligned with the Blue Economy, as formulated by Gunter Pauli.
Industrial waste heat is exactly what the Blue Economy describes: an abundant, local, untapped resource that can generate multiple cycles of value. One source. Many uses. Zero extra extraction.
- Every waste is a resource
- Every flow can create value
- Economy must mimic the living
- Profitability and regeneration go hand in hand
ENERGY SOVEREIGNTY
For oil-poor nations, recycling heat is repairing the trade balance
France imports more than €50B of fossil energy every year. Germany, Italy, Japan, Korea, India — most major industrial powers without hydrocarbon reserves live with a structural energy deficit.
Every wasted thermal kWh is energy invoiced abroad. Every kWh recovered on-site means less gas, less oil, less geopolitical dependency.
Our technology is not only a climate lever. It is an industrial sovereignty tool: produce more with what is already paid for, already on the territory, already controlled.

APPLICATIONS
Where the heat is waiting to be harvested
Seven domains where waste heat is being dissipated today — and where our technology plugs in without disrupting the existing process.
Stationary engines
Gas, biogas, diesel, hydrogen: exhaust heat recovery to lift overall plant efficiency.
Extra electricity, compressed air, or direct mechanical assist.
Maritime transport
LNG carriers and thermal-propulsion vessels in continuous regime: onboard heat recovery to improve propulsive efficiency.
Decarbonize shipping without breaking the propulsion stack.
High-temperature fuel cells
SOFC, MCFC for data centers and micro-grids: direct conversion of process heat into useful power.
Toward sober digital infrastructure that produces net energy.
Industrial circular economy
Recycle the heat where it is produced: less waste, less primary energy, fewer emissions. Nothing extracted, nothing displaced.
Heat becomes a local industrial asset.
Regenerative industrial capitalism
A productive ecology where falling emissions and rising margins move together.
Produce better, not less.
Decentralized energy networks
Industrial sites and campuses as local heat reservoirs, integrated into resilient micro-grids.
A more efficient, sober, durably competitive industry.
MANIFESTO
What we believe
We refuse the opposition between growth and planet. We build systems where they advance together.
- 01
The ecological transition won’t succeed against industry, but with it.
- 02
Technology can repair what it once made inefficient.
- 03
Wasted heat is one of the greatest energy opportunities of the 21st century.
- 04
Sobriety also runs through cutting-edge engineering.
- 05
Regenerative capitalism is not only possible — it is necessary.
HORIZON 2036
Our 10-year goal
To have contributed to halving emissions linked to industrial energy waste.
To have proved that wealth can be created by repairing the world’s inefficiencies.
“Heat is not a waste. It is wealth.”
