Abstract
The Vortex‑Jet V‑J1 is a 12‑volt, open‑hardware combustion heater that uses a vortex‑stabilized chamber with triple‑sawtooth J‑grooves and a dendritic fin assembly (Arachne #23) to improve burn efficiency and thermal management. Bench testing indicates approximately 3,500 BTU/hr thermal output, with combustion efficiency near 98% and carbon monoxide levels below 50 ppm measured at 0.5 m from the exhaust. The system integrates a 7075‑T6 aluminum combustion core, a TiO₂‑reinforced outer shell, a 12V variable‑frequency fan, and an ESP32‑based controller with fail‑closed fuel logic and optional LoRa telemetry. The prototype bill of materials is $285, with projected cost of $152 per unit at 1,000‑unit scale using cast components. All performance values represent engineering tests, simulations, or literature‑based models rather than field outcomes. The design is released under CERN‑OHL‑P v2 for humanitarian replication, research use, and global open‑hardware development.
