Turning waste heat into power

Where the world sees waste heat, we see work still waiting to happen — one of the largest energy sources on the planet, hiding in plain sight. We are building the engine that turns it into power.

The situation

Most of the energy
that industry pays for
is lost as heat.

Industrial waste heat below 300 °C is one of the largest untapped energy sources: worldwide, hundreds of TWh are vented unused every year.

  • In industry, about half of the energy that goes in is lost again — mainly as hot exhaust.
  • Much of this heat is not hot enough for today's equipment to use at a fair cost. So it simply escapes as paid but unused energy.
  • Fairlane turns this lost heat into clean electricity a site can use right away — with no extra fuel.
Free & green energy as infrastructure

The largest untapped
fuel on earth.

A new way to harvest lost energy. Recovering even a fraction reshapes the economics of electricity without changing everything again.

  • Cement, steel, chemicals, food & beverage — the largest reservoirs of recoverable heat.
  • Convert compute exhaust into local electricity and district heating.
  • Near-silent modules close to demand, minimal transmission losses.
  • Convert compute exhaust into local electricity and district heating.
