Development was guided by our desire to develop appropriate technology to create sustainable and equitable living, to localize production and work towards abolishing poverty.
 
At OSE, we believe that local manufacturing has the capacity to create a more equitable and pleasant world. We decided that a CEB press could help localize production in three ways: by schools, houses etc. to be built easily, by selling the bricks and by selling the presses.

In short, the development process cycles through two prototypes of the CEB machine itself, and two prototypes of an XYZ, computer controlled torch table (see [http://www.torchmate.com/industrial/index.htm professional version] and [http://openfarmtech.org/index.php?title=Torch_Table open source version]). The torch table will be used to automate the fabrication of the CEB machine, reducing fabrication time by an estimated 20 hours, and thus, also reducing the cost of the final product.
 
The development timeline also includes building actual structures to test the quality of the blocks and durability and ease of use of the press. Moreover, we will build a production facility for the CEB machines, and develop an open source business model to disseminate production of these machines to other areas of the world.


Future phases for CEB evolution that we are considering beyond the present funding cycle are:
#Fully automated CEB machine, like The Liberator, where manual controls are replaced with automoatic valves and a control circuit. The only control required is turning the machine on, and from that point one simply loads soil and unloads bricks. Added material costs in this version are approximately $500.
#More powerful machines. More speed may be achieved by
##A dual machine, which features 2 compression chambers operating in parallel
##Faster machine by virtue of redesign to allow faster cycling through the steps

This timeline shows the development cycles on top, along with the corresponding funding cycles and deliverables in green and red. For each development cycle, we adapt a 10-step procedure, whose steps are shown at the bottom of the diagram.

In short, the development process cycles through two prototypes of the CEB machine itself, and two prototypes of an XYZ, computer controlled torch table (see professional version and open source version). The torch table will be used to automate the fabrication of the CEB machine, reducing fabrication time by an estimated 20 hours, and thus, also reducing the cost of the final product.

The development timeline also includes building actual structures to test the quality of the blocks and durability and ease of use of the press. Moreover, we will build a production facility for the CEB machines, and develop an open source business model to disseminate production of these machines to other areas of the world.
