Our Mission

Energy stored as heat — not chemistry. Not combustion. Not radiation.

Ferro-Silex Energy Systems is developing the FSC-6.3 Titan — a non-nuclear thermal energy storage platform built for the most demanding environment humans have ever attempted to inhabit: the surface of the Moon.

Where lithium batteries fail in extreme cold, where solar panels go dark for 14 days, where radioactive payloads require years of regulatory clearance — the Titan operates. Silently. Without moving parts. Without toxic chemistry. Without fear of fire.

The same platform that survives the lunar night will power the homes and highways of Earth. One technology. Three markets. Unlimited potential.

The Technology

FSC-6.3 Titan
Thermal Energy Platform

01 — Core
Encapsulated Core Dynamics
High-purity silicon elements micro-encapsulated inside proprietary refractory diffusion barriers, suspended in a structurally stable, ultra-high-density matrix. At peak thermal thresholds, the core safely locks in latent phase-change heat with perfect consistency across extended cycles.
High-Cap
Latent heat storage
02 — Conversion
Rad-Hard TPV Array
Solid-state thermophotovoltaic (TPV) semiconductor cells convert core radiant energy directly into clean electricity. Zero moving parts. Radiation-hardened for extensive lunar surface exposure with minimized power degradation over a multi-year mission lifecycle.
>40%
Theoretical efficiency
03 — Containment
Multi-Barrier Insulation
A multi-shield thermal isolation assembly utilizing high-vacuum spacing, localized structural standoff pins, reflective foil layers, and an impact-resistant outer structure. The entire vessel is built to maintain intense core temperatures internally while maintaining ambient exterior skin levels.

Applications

One platform.
Three frontiers.

◎
Lunar Surface
Primary Application · NASA Artemis
354-hour discharge covers the full 14-day lunar night. Zero radioactive materials. No regulatory burden at Kennedy Launch Centers. Compatible with projected infrastructure. A patent-pending non-nuclear alternative to traditional RTGs and surface fission systems.
⌂
Residential Storage
Near-Term · Home Energy Independence
One compact utility footprint matches multiple chemical battery blocks and handles direct thermal load routing. No lithium-ion constraints, zero thermal runaway risk, and no degradation pipelines. A secure alternative for long-duration residential safety.
▶
Heavy Transport
Future · Long-Haul Electrification
Heavy freight haulage faces critical payload-to-weight issues under standard chemical infrastructures. The high energy storage density of our solid-state core layout offers a zero-emission path for heavy transport architectures without destroying payload limits.

Let's build
the future.

Ferro-Silex Energy Systems is actively seeking research partnerships, NASA SBIR collaboration, and technical feedback from the scientific community.
