American Fusion Inc. (OTCQB: AMFN) Outlines Texatron™ Plasma Compression and Confinement Approach in New Technical Analysis

FORT WORTH, Texas, Sept. 29, 2026 (GLOBE NEWSWIRE) -- American Fusion Inc. (OTCQB: AMFN) (“American Fusion” or the “Company”), developer of the proprietary Texatron™ Fusion Engine™, today announced that Chief Technology Officer Dr. John E. Brandenburg has completed a technical analysis describing the proposed plasma-formation, compression and confinement approach underlying the Texatron™ development program.
In everyday terms, Texatron™ is designed to use a brief, powerful magnetic pulse to squeeze a doughnut-shaped ring of plasma, an electrically charged gas, so that it becomes hotter and denser. Grooves inside the chamber are intended to help shape the magnetic field and keep the plasma organized during that squeeze. The challenge is to make the plasma hot enough, dense enough and confined long enough for fusion, then recover the released energy as electricity. The analysis describes a theoretical framework and development objectives.
The report, An Analysis of the Texatron™ Concept for the Creation and Confinement of Toroidal Plasmas for Fusion Experiments, brings together the proposed physics, earlier low-temperature experiments and the questions the Company’s testing program is working to answer.
Pulsed Compression and Rifled Chamber Geometry
Texatron™ uses energy stored in a capacitor bank to create a brief, strong magnetic pulse. That pulse is intended to squeeze the plasma inward. Compression and shock waves heat the plasma as it becomes denser. The analysis considers how to time the pulse so that the plasma reaches its tightest compression near the peak magnetic field, then has time to settle into an organized state.
The chamber’s spiral grooves or ridges are central to what Brandenburg calls the Rifled Toroidal Pinch, or RTP. His analysis proposes that electrical currents flowing along this shaped surface could create a twisted magnetic field and pass that structure to the forming plasma. The aim is to shape and compress the plasma together. Whether the design provides the intended confinement at higher energies remains a question for testing.
The report also examines whether the plasma can retain key features of its magnetic structure as it forms and settles. Its “Double Invariant” framework considers magnetic helicity, related to the linkage and twist of magnetic fields, and a second flux property called “baricity” in the report. Brandenburg proposes that preserving these features could help the plasma remain in balance under pressure. This remains a theoretical explanation to be tested under fusion operating conditions.
Prior Experiments and Further Validation
The report reviews earlier experiments in which plasma was formed inside a rifled toroidal chamber within a vacuum system. Brandenburg reports that, under the low-temperature conditions used, the plasma settled into a relatively quiet state, separated from the chamber walls, and persisted for periods on the order of one second. That observation is relevant to the confinement concept, but it does not demonstrate one-second confinement at fusion temperatures or production of fusion energy.
The Company’s current work focuses on producing plasma consistently; measuring temperature, density, magnetic-field strength, compression and confinement; and evaluating how chamber geometry affects plasma behavior. The testing is aimed at determining whether the intended magnetic structure forms and holds together as operating conditions become more demanding.
“If our continuing experiments demonstrate that we can reproducibly create the required temperature, density and confinement while preserving these magnetic invariants, it would represent an important step toward the ultimate objective of controlled D-³He fusion and direct electrical energy conversion. That is the physics path we are now testing,” said Dr. John E. Brandenburg, Chief Technology Officer of American Fusion.
“The next stage is about measurement, repeatability and continuing to convert Dr. Brandenburg’s theoretical framework into experimental data,” said Fabrice David, an independent director of American Fusion who has observed the Company’s recent testing program.
Fusion Fuel and Direct Energy Conversion Objectives
Texatron™ is being developed to use deuterium and helium-3 (D-³He) as fusion fuels. The primary reaction produces energetic charged particles. In the Company’s proposed design, their energy would heat the plasma and cause it to expand against the surrounding magnetic field. That expansion would change the magnetic flux and induce electrical current in surrounding conductors, an approach intended to recover electricity directly, rather than first producing steam to drive a turbine.
The analysis includes calculations for the very high temperatures and densities the proposed system would require, including ion densities on the order of 10¹⁷ per cubic centimeter and pre-ignition temperatures of several kiloelectronvolts. These are theoretical design assumptions, not measured Texatron™ performance or demonstrated ignition thresholds.
Fusion ignition, net energy gain and direct conversion of fusion energy into electricity remain development objectives that Texatron™ has not demonstrated. Further experiments must establish the required combination of temperature, density and confinement, measure fusion reaction products if produced, and evaluate whether energy can be recovered as proposed.
