One of the features of The Liberator open source CEB press is that it is designed for disassembly. Here we show how we take the machine apart in a couple of hours, down to the main frame section and all other parts. It flattens from 83 inches of height to about a 1 foot high package.

I’ve run some numbers. It’s still early times but this gives some idea of some potential.
The Liberator can help humans who have soil to make let’s say 12 bricks a minute.
If the machine is run in shifts, 10 hours a day would give, allowing for some not-so-good bricks … 12x60x10=7200 … let’s say 5000 bricks a day, or more.
A 2-room home has 7 walls. If one wall uses say 250 bricks, that’s 7×250=1750 bricks per home. Let’s say this is for Haiti and we want half a room per person to start with, so 1750 bricks is room for 4 people, at 440 bricks per person. Let’s use 450 bricks per person for easier computation.
450 x 1 million people (Haiti’s homeless) / 5000 = 90000 machine-days = 3000 machine-months = let’s say 300 machines for one year.
Does it make sense for someone with physical capacity in Haiti to run a pledge for $6000 (parts, labor, transport) so that there will be one Liberator in Haiti within, say, a month, to start testing this?
How close are we to start seeing things like this?
Also, in another area, how much fuel per brick? And how much metal and time if they wanted to make 299 machines themselves?
Guys, you’re focused and you have lots to do, so of course someone else will or will not do the other work. But if you have at least some ballpark estimate of those figures maybe someone will start pushing the idea, which will or will not materialise cos, after all, these are just options.
Great work! Thanks for keeping us informed!
Marcin,
please check out the “gridbeam” building system in future projects. This allows for easier re-use of all kinds of components and makes the whole assembly process even more accessible. There is one book out there on Amazon. The gridbeam idea has been around for decades, but somehow this hasn’t caught on.
We are aware of Gridbeam, and we feel that it is way underutilized. Our experience with it shows that the barrier to its widespread use is the time required to drill the holes. At the same time, we are using the Gridbeam concept in the LifeTrac frame. If we add full CNC torch table capacity to our operations, then we will be able to produce metal grid beam on demand in a matter of minutes per 8′ foot piece, for applications such as LifeTrac.
