This is a general development-stage reference. This company's or project's precise stage is unconfirmed, so no position is assigned. Development pathways vary by technology and business.
Avalanche Energy is a US company building small fusion machines and high-voltage components used in their development. It aims eventually to supply portable, modular power while developing neutron-testing services along the way. Its current stage is machine experimentation and component commercialization—not verified commercial fusion generation or net electricity supply.
What small machines aim to achieve—and how Orbitron works
Founded in 2018 and based in Seattle, Avalanche emphasizes short hardware-development cycles. Company overview Orbitron confines fast ions around a negatively charged electrode; magnetic fields also confine electrons. An electrostatic emphasis should not be simplified to “no magnets.” Machine description
The technology page’s 1–100 kWe range is a development objective, not measured electrical output. Technology overview A small reaction core is not the same as a small complete facility including vacuum, cooling, shielding and power supplies. Manufacturability and energy production exceeding losses require separate evidence.
Holding 300 kV is not demonstrating fusion gain
The company reports maintaining 300,000 V steadily across approximately 2.5 inches while drawing 3 W in that test. High-voltage experiment Voltage is an electrical potential difference, not fusion output or generating efficiency.
The 3 W figure must not be treated as total consumption including ion sources, pumps, cooling and diagnostics. Nor should figures from different machines or conditions be combined into an apparent net-gain calculation. Insulation, particle confinement and energy accounting are separate experimental questions.
Distinguishing Jyn temperatures from Lando’s licensed yield
On 10 June 2026, Avalanche reported measurements corresponding to apparent ion temperatures above 1 keV in Jyn, using optical emission spectroscopy. Jyn announcement The public technical-memo description calls the device a centrifugal mirror; its result must not be transferred directly into whole-Orbitron power performance. Memo introduction
Lando’s page gives 10¹⁰ n/s as a licensed neutron yield. Lando An authorized value is not proof that the machine measured and sustained that output. Temperature, density, confinement time and actual neutron yield need matched conditions. This profile does not reconstruct calculations or uncertainties from the inaccessible full memo.
Hammerhead is a high-voltage product, not a fusion generator
Hammerhead transfers high voltage across a vacuum boundary. The official page offers a 300 kV class and mentions 200 kV products; smaller 50 kV and 100 kV versions are described as forthcoming. Product page Commercializing an insulating vacuum component is different from selling a fusion power generator.
Buyers need to check interfaces, vacuum conditions, maintenance and compatibility—not voltage alone. Product availability does not establish shipment numbers, revenue or lifetime across customers. The sources reviewed did not establish that Avalanche sells HTS tape or superconducting magnets, so those are not added to its product list.
Ion-source delivery is concrete integration evidence
In a release posted on 2 July 2025, supplier D-Pace stated that an ECR ion source had been installed at Avalanche and experiments were underway by May. It followed an earlier ion-source purchase and included beam-optics support. Supplier announcement
This is evidence of integrating external equipment, not net fusion electricity. Injected particles, the fraction contributing to reactions, losses and equipment life require separate assessment. Interfaces between suppliers and machine developers are an important industrial question.
Read FusionWERX’s schedule separately from its marketing
FusionWERX is described as a neutron-testing platform for materials and equipment. Its official page explicitly schedules Cell One customer irradiation with 14.1 MeV neutrons for Q2 2027; Cell Two is a future expansion. Facility schedule
Present-tense descriptions of the business should not convert scheduled capabilities into sustained customer-delivery achievements. Compare neutron energy, source rate, flux at the sample, irradiation duration and sample handling separately. Useful neutron services and net electricity generation are also different propositions.
The October 2026 manufacturing announcement is a plan
The 8 October TRIDEC announcement describes cooperation on a Tri-Cities manufacturing site, permitting, infrastructure and workforce preparation. The 100 kW and 5 MW capacities are targets; Q>1 before 2030 is also a company objective. Manufacturing plans
Regional selection, factory construction, production startup and customer handover are separate milestones. An aspiration for hundreds of machines annually is not current manufacturing capacity. A Q>1 claim also needs a defined input–output boundary before it can be interpreted as net electricity at the grid connection.
Evidence to track and useful comparisons
Track voltage stability, measured particle conditions, actual neutron yield, component sales, testing services and energy accounting separately. Compare matched conditions rather than combining the best figures from successive machines into one performance claim. Manufacturing and maintenance improvements matter but cannot substitute for physics validation.
Astral Systems offers another example of a neutron-first business pathway; UKAEA provides context on testing infrastructure. These are editorial comparisons, not claims of partnerships with Avalanche. Review date: 30 October 2026. No rights-cleared photograph is attached to this profile.
