The technology
Motion to heat, in one step
ROTATEMP is built on a simple idea from physics: spin magnets past metal and the metal heats up. We put that principle to work for real buildings, farms and remote sites.
The principle
What eddy currents are
When a conductor meets a changing magnetic field, circulating loops of current — eddy currents — are induced inside it. The conductor resists those currents, and that resistance releases energy as heat. It's the same effect used in induction cooktops and eddy-current brakes.
ROTATEMP arranges magnets on a rotor. As the rotor turns, the field seen by a nearby conductive mass changes constantly, so eddy currents flow and the mass warms up. That heat is then moved to the space that needs it.

The pathway
From rotation to a warm room
Four stages — and none of them is a generator or a resistance heater.
1 · Capture
A wind rotor or other rotary source spins the shaft. Rotor size is matched to the site's wind and heat load.
2 · Induce
Magnets on the rotor sweep past a conductive mass, inducing eddy currents inside it.
3 · Heat
The mass warms as eddy currents dissipate. Motion becomes heat directly in the metal.
4 · Deliver
Heat is transferred to air or fluid and carried to the greenhouse, barn, room or process.
wind → electricity → heater → heat
Why the direct path
Cutting out the conversions
The common route turns wind into electricity, then back into heat through a resistance element. Every conversion adds hardware, cost and points of failure.
- Simplicity: the heat is made mechanically, so there's no generator, inverter or heating element in the heat path.
- Durability: a sealed, low-part-count drivetrain suits harsh and remote environments.
- Flexibility: any rotary input works, so the same core serves wind, hybrid and marine platforms.
Questions
Technology FAQ
What is an eddy current?
A loop of electric current induced inside a conductor when it sits in a changing magnetic field. The conductor's own resistance turns that current into heat.
Why skip electricity generation?
Going wind → electricity → resistance heater adds components and conversion losses. ROTATEMP uses the rotation to produce heat directly, reducing steps and parts.
Does it work without wind?
Yes. Wind is the primary input, but any rotary motion source can drive the core, and solar can be paired to offset energy depending on the site.
Is this proven technology?
The underlying physics of induction and eddy-current heating is well established. ROTATEMP applies it to distributed cold-climate heating. Performance numbers on this site are concept-level and should be validated against measured prototype data for any specific project.
Want the engineering detail?
We're happy to walk through the core, the platforms and where the concept still needs validation.
