Iron Nitride builds rare-earth-free power systems from 1 KW to 1 MW, daisy-chainable into gigawatt fleets. Iron and nitrogen — the two most abundant elements between us and the megawatt.
Start with Joe Shepard's split-rotor multiphase generator — proven mechanical architecture, three-phase output, modular. Then swap out every rare-earth dependency. NdFeB rotor magnets are replaced with iron-nitride Fe16N2 at 2.4 T saturation. Silicon-steel stator laminations are replaced with sintered iron-nitride Fe4N at 1.9 T, made in the same nitriding plant as the rotor magnet at a different nitriding potential. Every element in the magnetic path is iron and nitrogen — abundant, domestic, non-strategic.
Segmented Fe16N2 magnets with a carbon-fiber sleeve hold every segment in compression at the 12,000 rpm worked example. Air-gap flux comes from concentrating two magnets into one narrower pole piece, not from a stronger magnet.
Read the physicsγ′-Fe4N sinters to a solid core at roughly 1.9 T saturation, above silicon steel, with no rare earth in it. It leaves the same nitriding plant as the rotor magnet, at a different nitriding potential.
Read the physicsChina controls ~95% of neodymium refining. Iron is the fourth most abundant element in the Earth's crust and nitrogen is 78% of the atmosphere. Zero strategic exposure, defense-qualifying by construction.
Read the supply modelEvery performance metric that matters — saturation, coercivity, Curie point, core loss, supply exposure — moves in the direction we want. This is what replacing the world's most expensive metal with the world's cheapest metal buys you.
Eight discrete generator ratings share one physical language: same housing geometry, same three-phase output, same magnetics — only the scale changes. Buy one for a commercial building. Buy 200 for a data center. Buy 1,000 for a city. The economics are linear because the manufacturing is.
Shoebox-sized. Runs a small office, telecom cabinet, or remote instrumentation.
Suitcase-sized. Whole-house prime power or diesel-genset replacement.
Mini-fridge-sized. Multi-tenant retail, agricultural, small-fleet charging.
Washing-machine-sized. Primary industrial load, cold storage, machine shops.
Double washing-machine crate. Sweet-spot economics for edge data centers.
Utility cabinet. Base-load or peaking, campus microgrid, industrial park.
Tall server-rack format. Direct substation interconnect, hyperscale bays.
Refrigerator-sized field unit. Daisy-chain 200 for 200 MW hyperscale. Base unit for gigawatt fleets.
Four short films on the parts of the design that are hardest to explain in a spec sheet: where the magnetism comes from without rare earths, what the capacitance actually does to the current phase, and why the switching instant matters more than the switch.
Explainer animations — illustrative, not measured performance data.
Every 40-foot ISO container fits four 250 KW bays or one 1 MW rack. Concrete-pad delivery, three-phase interconnect, overhead bus-bar, done. Fleets are daisy-chained by containers rather than by circuits — commissioning is a forklift and a torque wrench, not a substation redesign.
Iron Nitride ships as one primitive inside a larger power-and-intelligence platform. ROSE photovoltaics feed the same three-phase bus. xELECTRICITYx delivers the retail contract. Enwatel handles supply-chain and finance. xSMARTLINKx tracks assets and warranty. HALO health-monitoring watches every rotor bearing. The buyer sees one platform, not ten vendors.
The whole cost model of AI is bottlenecked on interconnect queue times and rare-earth exposure. Replace both variables and the megawatt-per-year deployment number is the only number left to argue about.
