MacroInvent LLC & current focus

This site is the public face of MacroInvent LLC — space settlement design work, conference talks, and educational writing for inventors and entrepreneurs.

The profile page that collected speeches and articles is now the root of a small LLC. Work continues on design portfolio materials, analog operations (including EVA Link), and methods writing. Two related product sites may appear later; this domain remains the long-term public face for MacroInvent.

Mars Desert Research Station — Crew 329

Commanded MDRS Crew 329 in Utah with a focus on updated habitat technology, suit tests, and EVA Link field work.

The one-week mission included live outreach with crewmate Cody Reeder, pressurized spacesuit prototype tests, relay work for Crew EVA Link, and analog experiment runs. Personal projects included a stratospheric balloon attempt (weather scrubbed) and scale rover-train trials on dry, crumbly soil.

eBook — Becoming Inventive
