	We are offering a high-performance, open source, Compressed Earth Block (CEB) Press - The Liberator. This is a CEB machine shown [http://~~openfarmtech~~.org~~/weblog~~/?p=1204 here]. It does not include the tractor or power source - just the machine with manual, hydraulic controls. The machine includes a large hopper and a shaker grate for sifting soil into the hopper. The power source is external. This is part of our strategy to obtain a high-power, low-cost machine.

The power source is external. This is part of our strategy to obtain a high-power, low-cost machine.

	A CEB machine like this is not a toy. It is not designed to be loaded by hand - as it would take about 32 people to load it by hand to keep up with its proven demand for soil. Soil handling is a major requirement at this scale, and requires a tractor loader plus some way to pulverize the soil. If you are interested in a machine that you can load by hand, just get a hand-operated (non-powered) Cinva Ram or similar for $200-$500. You will save yourself the cost of purchasing a machine that you will not be able to use effectively without a tractor and soil pulverizer. We learned this the hard way with our first prototype.

	Doesn't it make sense to have a dedicated engine on the machine? We don't think so. Any construction site at the scale of building intended for this machine will have a tractor or skid loader on site. Auxiliary hydraulic power can be used from these machines to operate the CEB press. We favor the [http://~~openfarmtech~~.org~~/weblog~~/?p=814 Power Cube] for a power source. You can get a PTO-driven hydrauilic power source for about $800.		Doesn't it make sense to have a dedicated engine on the machine? We don't think so.

	The external power source strategy of [[FeF]] is designed such that a large number of machines, including tractors, have interchangeable power sources. This allows an entire mechanical infrastructure of a 10-100 person village to thrive with the assist of a total of 40-80 hp in engine power. For us, we're exploring modularizing this to 20 hp Power Cubes. This way, a machine can utilize 20 hp as needed, or several PowerCubes can be attached to another machine, such s 4 Power Cubes for a bulldozer. We're going further on this to develop steam power, with locally grown, [[pelletized biomass]] as the fuel source.

	The data was obtained using raw soil from near the machine. Topsoil was scraped off, and the [[Soil Pulverizer]] was used to prepare the soil.

The data was obtained using raw soil from near the machine. Topsoil was scraped off, and the [[Soil Pulverizer]] was used to prepare the soil. Brick thickness is determined in [[The Liberator]] II prototype by timing the compression stroke until full compression occurs with 2300 psi.

			An alternative route to perfecting thickness uniformity relies on a limit switch, which stops compression at a preselected thickness. As of 12.15.09, this is currently being implemented.
