Open Source Ecology (OSE) is a network of farmers, engineers, architects and supporters, whose main goal is the eventual manufacturing of the Global Village Construction Set (GVCS).

[3] Groups in Oberlin, Ohio, Pennsylvania, New York and California are developing blueprints, and building prototypes in order to test them on the Factor e Farm in rural Missouri.

The initiative has prototyped the Seed Eco-Home[13] – a 1400 square foot home with the help of 50 people in a 5-day period – demonstrating that OSE's Extreme Manufacturing techniques can be applied to rapid swarm builds of large structures.

[14] For 2020, OSE was planning its most ambitious collaborative design effort by hosting an Incentive Challenge on the HeroX platform – to produce a professional grade, open source, 3D printed cordless drill that can be manufactured in distributed locations around the world.

This effort was postponed due to COVID-19, and OSE has pivoted to a product release of the Seed Eco-Home in 2021 to address the need for affordable, ecological housing.

[21] The Global Village Construction Set (GVCS) comprises 50 industrial machines:[25][26] Compressed earth block press v4 · Concrete mixer · Sawmill · Bulldozer · Backhoe Tractor: LifeTrac v3 · Seeder · Hay rake · Microtractor · Rototiller · Spader · Hay cutter · Trencher · Bakery oven · Dairy milking machine · Microcombine harvester · Baler · Well-drilling rig Multimachine (milling machine, drill press, and lathe) · Ironworker · Laser cutter · Welder · Plasma cutter · Induction furnace · CNC torch table · Metal roller · Wire and rod mill · Press forge · Universal rotor · Drill press · 3D printer · 3D scanner · CNC circuit mill · Industrial robot · Woodchipper / Hammermill Power Cube: PowerCube v7 · Gasifier burner · Solar concentrator · Electric motor / generator · Hydraulic motor · Nickel–iron battery · Steam engine · Steam generator · Wind turbine · Pelletizer · Universal power supply Aluminium extractor · Bioplastic extruder Car · Truck The first time a Global Village Construction Set product was created by another group was in October 2011; Jason Smith with James Slade and his organization Creation Flame[27] developed a functioning open source CEB press.
