Investor brief

Truck-sized fusion modules for defense, space and remote industry

Executive Summary

Avalanche Energy is building micro-fusion 'batteries' — kilowatt to megawatt-class fusion devices designed to compete with diesel gensets, RTGs and small reactors before scaling to grid power. Its Orbitron architecture uses magneto-electrostatic confinement to trap ions in stable orbits at fusion-relevant energies inside a desk-sized device.

Strategic Thesis

Skip GW plants entirely — build truck-sized fusion modules that compete with diesel gensets and RTGs first, then aggregate to grid.

The Problem

Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.

Orbitron — Magneto-Electrostatic Confinement

The Orbitron combines magnetic and electrostatic fields to confine ions on closed orbits, achieving high ion energy in a small volume without the bulk and cost of large magnets or lasers.

Magneto-Electrostatic Trap

Electrostatic potentials accelerate ions to fusion energies; magnetic fields suppress losses to the electrodes.

Modular Form Factor

Each Orbitron unit fits in a shipping container. Power scales by aggregation, not by building a single massive reactor.

Defense and Space Applications

Multiple DoD SBIR awards target compact fusion neutron sources for radiography, nondestructive testing and space propulsion.

Fuel Strategy

D-D / D-T (Modular)

Fuel choice depends on application: D-D for neutron sources, D-T for higher power density where licensing allows.

Product Platform

Orbitron Testbeds

Operating laboratory devices proving magneto-electrostatic confinement.

Fusion Battery Modules

Future kilowatt-to-megawatt distributed fusion units for defense, remote sites and space.

Energy Conversion

Economic Vision

By targeting markets where the alternative is diesel at $1/kWh or a custom RTG at much higher cost, Avalanche bypasses the grid-scale economic threshold that gates every other fusion company.

Vision

Distributed fusion power that displaces diesel everywhere it runs today.

Mission

Build small, mass-manufacturable fusion modules with real customers from day one.

The description above reflects Avalanche Energy's publicly stated technology goals, roadmap and architecture. Many elements — particularly net-energy gain at scale, advanced fuel cycles, and grid-relevant economics — remain ambitious objectives that have not yet been demonstrated commercially anywhere in the fusion industry. Forward-looking statements should be treated as engineering targets, not certainties.
