The Breadboard Project: a functioning CELSS plant growth system

Abstract

The primary objective of the Breadboard project for the next 3-4 years is to develop, integrate and operate a Controlled Ecological Life Support System (CELSS) at a one person scale. The focus of this project over the past two years has been the development of the plant growth facility, the first module of the CELSS. The other major modules, food preparation, biomass processing, and resource recovery, have been researched at the laboratory scale during the past two years and facilities are currently under construction to scale-up these modules to an operational state. This paper will outline the design requirements for the Biomass Production Chamber (BPC), the plant growth facility for the project, and the control and monitoring subsystems which operate the chamber and will present results from both engineering and biological tests of the facility. Three production evaluations of wheat, conducted in the BPC during the past year, will be described and the data generated from these tests discussed. Future plans for the BPC will be presented along with future goals for the project as the other modules become active.
