I build open-source appropriate technology: practical thermal, shelter, materials, energy, and local-first computing systems that can be understood, tested, repaired, and shared.
- OpenRoot — public ecosystem hub, evidence standards, and repository map
- AeroCement — lightweight construction-material research
- Black Locust RMH — rocket-mass-heater thermal cascade
- OpenCell Thermal System — thermal storage and passive-system research
- Design-packet template — reproducible open-hardware project structure
evidence → documentation → buildable action → measurement → correction → shared capability
I favor low-resource, repairable, offline-capable systems; open documentation; explicit constraints; and claims that can be checked against measurements.
The account is being consolidated into a small number of clear public projects. The OpenRoot repository map identifies active projects, templates, reference material, archives, and external forks.
