FOR INVESTORS
THE INVESTMENT THESIS
Horne is pursuing that ambition through hybrid confinement, rapid prototyping, and simulation informed by experimental data. The aim is to focus development resources on the design decisions that matter most.
Magnetic field simulation.
HOW WE BUILD
Simulation, fabrication, and testing under one roof keep the feedback loop close. Our focus is on improving the model, testing its predictions, and using each experiment to inform the next step.
THE FUSION LANDSCAPE
Hybrid confinement: inertial electrostatic heating paired with a superconducting, magnetically shielded grid.
Our design goal is modular, scalable energy. Current development connects an operating prototype with in-house simulation and hardware iteration.
A tokamak using high-temperature superconducting magnets. SPARC is its demonstration machine; ARC is its planned power plant.
Both approaches use superconducting technology. CFS applies it to a tokamak; Horne uses magnetic shielding within a hybrid electrostatic design.
Pulsed field-reversed configuration (FRC) plasmas, targeting deuterium–helium-3 fusion and direct electricity recovery.
Shares an emphasis on building and iterating hardware. Its pulsed FRC architecture and direct electricity strategy differ from Horne’s hybrid confinement approach.
An advanced beam-driven field-reversed configuration (FRC), with hydrogen–boron as its intended commercial fuel.
Also pursues an alternative to tokamaks. TAE uses neutral beams to support its FRC plasma; Horne’s design centers on electrostatic heating and magnetic shielding.
Magnetized Target Fusion: mechanical compression of magnetized plasma within a liquid-metal system, designed to capture heat for electricity generation.
Combines magnetic confinement with compression. Horne’s hybrid design instead pairs electrostatic heating with a magnetically shielded grid.
Based on company technical descriptions reviewed October 20, 2026. Comparisons are Horne’s summary of those descriptions. Design goals are not demonstrated commercial performance; the entries do not imply equal technical maturity.
LET’S TALK
The next conversation starts with experimental results, the technical roadmap, and what the next phase of development is intended to demonstrate.
