In 2007, Jakubowski began working on a minimum set of machines necessary to sustain a modern civilization. It comprises bread ovens, aluminum smelters, tractors, brick presses, and 46 others. Factor e Farm has already built 15 of these devices, including a computer-controlled torch table that can cut intricate patterns on metal with a jet of superheated ionized gas. Work will com-mence soon on a cement mixer, a sawmill, and an industrial robot....

Jakubowski expects to have all 50 tools finished by 2015 and publishes progress reports on the Open Source Ecology website. He shares the designs for all the machines and produces how-to-make-it videos. He wants as many people as possible to take a crack at improving the designs.
