01 — The Challenge
The world needs fusion. Fusion needs tritium.
Tritium — the hydrogen isotope essential for fusion — barely exists on Earth. Global supply is roughly 20 kg per year, all produced as a byproduct of heavy-water fission reactors that are shutting down. Every fusion effort depends on breeding more tritium than it burns. The industry target is a Tritium Breeding Ratio above 1.15.
Most designs struggle to reach even 1.1. This is fusion's chicken-and-egg problem.

02 — The Insight
We're not making power. We're making the fuel for the power.
TITAN-SEA is a fuel factory first, power plant second. With a TBR of 2.40, every reactor produces 140% more tritium than it consumes — breaking fusion's supply bottleneck forever.
🔄
Self-Sustaining Cycle
TBR 2.40 means each reactor feeds itself and has surplus to start new reactors. No external tritium supply ever needed.
🏭
Tritium Export
Surplus tritium at $30,000/gram — the world's most valuable fuel. Supply every fusion program on Earth.

Nuclear Batteries
Proprietary nuclear battery technology with 50+ year life and extreme energy density. Details under NDA — let's just call it our secret sauce.
🧲
Self-Growing Magnets
A proprietary decay pathway produces advanced superconducting material. The reactor grows its own magnet material. Secret sauce.
03 — Our Approach
Seawater in. Clean energy out.
TITAN-SEA reimagines the fusion fuel cycle. Natural lithium, free deuterium, boron, selenium, and carbon — all extracted from seawater — feed a self-sustaining reactor that breeds its own fuel.
In a counter-intuitive finding validated across 127 simulations, inexpensive natural lithium dramatically outperforms costly enriched Li-6 in the TITAN-SEA geometry. Adding just 0.1% borax to the lithium blanket boosts TBR by a further 15%. Together, these eliminate major cost barriers for commercial fusion.
Combined with B⁴V power scaling, 8 concentric beryllium shells forming a neutron maze (45° channels offset 15° per shell = 120° total path), and proprietary self-regenerating pressure vessels — TITAN-SEA doesn't just meet breeding requirements. It shatters them.
06 — Innovations
Thirteen design rules. Zero compromises.
Natural Lithium + Borax
32% better than enriched Li-6. 0.1% borax adds another 15%. Eliminates enrichment cost entirely.
Reactor produces its own Be, graphite, and proprietary advanced materials. Design Rule 13: grow your own parts.
B⁴V Power Scaling
Power scales with magnetic field to the fourth power × volume. Family: P-MICRO (213 MW) to GIGA-10K (7.14 EW).
07 — The Fuel of Fuels
Tritium decays. And that's the point.
Every tritium atom (³H) naturally decays into helium-3 (³He) — the rarest, most valuable isotope in existence. Surplus tritium from TBR 2.40 doesn't just fuel reactors. Combined with our proprietary storage method, it transforms into something extraordinary.
3K superconductor cooling enables 4M+ qubit quantum computers. Our secret sauce is the key to scalable quantum computing.
Room-Temp Superconductors
Proprietary advanced material — predicted room-temperature superconductor. The reactor grows its own magnet material. Secret sauce.
Store surplus tritium using proprietary method → wait 12.3 years → harvest advanced superconductors. Design Rule 13: the reactor that builds itself.
08 — The GIGA FORGE
A transmutation engine. Not just a reactor.
TITAN-SEA's neutron flux creates 17+ medical and industrial isotopes as byproducts. Every fusion cycle transmutes raw elements into humanity's most critical materials.
