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.

This was repeated ('''twice? three times?''') to arrive at the current version.


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.  
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.  


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.

#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.

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 chose a CEB press, because it could help localize production in three ways: by allowing schools, houses etc. to be built easily, by selling the bricks and by selling the presses.

This was repeated (twice? three times?) to arrive at the current 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.
