The generator
without the rare earth.
Fe16N2 rotor. Fe4N stator. A split-rotor multiphase generator, from 1 KW to 1 MW, daisy-chained to gigawatts. Iron and nitrogen. No neodymium. No China.
Every megawatt of modern generation still runs on a Chinese magnet.
The world's data centers, EV drivetrains, defense platforms, and wind turbines all depend on the same choke point: neodymium-iron-boron magnets. That choke point is one country, one supply chain, and one geopolitical decision away from a hard stop.
Supply-chain risk
~95% of neodymium refining happens in China. Every generator, drivetrain, and wind turbine built on NdFeB magnets inherits that dependency.
95% Chinese refiningInterconnect delay
Utility-scale projects wait years for grid interconnect. Behind-the-meter modular generation avoids the queue entirely.
3–7 yr Typical waitCost per watt
Legacy modular generation ships at $8–12/W installed. Rare-earth-free magnetics and shared architecture take us to $5/W at fleet scale.

The base generator is Bill Mercer's patented split-rotor multiphase architecture. Our substitution swaps two components and only two components.
Rotor magnets: NdFeB → Fe16N2
α''-Fe16N2 holds a saturation magnetization near 2.4 T (up to 3.1 T in strained films) versus NdFeB's 1.6 T. At equivalent air-gap flux the magnet volume drops by roughly 63%. Curie temperature reaches 361–540 °C against NdFeB's 315 °C, so the machine tolerates a wider thermal envelope.
Stator core: silicon steel → Fe4N
Sintered γ'-Fe4N runs with electrical resistivity up to 200× nanocrystalline soft-iron alloys. At 100 kHz switching the core loss falls from 4,048 MW/m³ (0.35 mm laminated Si-steel) to 1,297 MW/m³ – a 68% loss reduction without lamination complexity.
| Metric | Fe16N2 (ours) | NdFeB (legacy) |
|---|---|---|
| Saturation magnetization | 2.4 T (up to 3.1 T) | 1.6 T |
| (BH)max | ~143 MGOe | 56 MGOe |
| Curie temperature | 361 – 540 °C | 315 °C |
| Volume at equivalent flux | -63% | baseline |
| Feedstock supply | Iron + N (domestic) | Nd (~95% China) |
Eight ratings on one architecture. Daisy-chained to gigawatts.
Every unit uses the same split-rotor multiphase core, scaled by pole count, phase count, and cooling – not by redesign. Cable N units through a shared medium-voltage inverter frame and you have a fleet at any total capacity.
One clean, quiet box behind every load the country depends on.
Iron Nitride doesn't stand alone. It's the shared power substrate under a coordinated portfolio of energy, water, connectivity, defense, and longevity brands.
