April Production Run

Introduction

We have produced 4 Tractors, 4 CEB Presses, 9 Power Cubes, and 3 Soil Pulverizers in the OSE Production run of 2011 - from April to Sep. 2011. We cleared $25k - achieving a milestone of economic significance for OSE products. We featured the tractor at the Kansas City Maker Faire of 2011. This production run culminated in the build of our Workshop and HabLab living units - as a product of using the tractor, CEB Press, Soil Pulverizer, and Power Cubes. A documentary by Channel 21 from Berkeley - The Open Source Ecologist - and a piece by Land Rover Magazine also came out of this:
