Description

We are testing production using the CEB press. Digging compacted clay is difficult in practice. For more information and to support our work - see:

A

This is Alex Ron and my first day, I factory farming we've had an exciting afternoon, working on the seat, press and margins here and he's going to do a drop test on one of our fresh bricks with the new patch of clay. Oh, do it again, do it again.

B

Well, Martian.

A

The brick isn't breaking no.

B

It's gonna break right here. There.

A

C

No, that was soft there that.

A

Was great okay? So what would you like to say about this brick? It's.

B

Got big clumps of clods of clay instead of very little pieces, plus there's a little bit of grass in there and makes it doesn't bind together well, but it's good soil if we dig a little deeper so so.

A

We've been talking about using this particular clan drying it out and in the area where we're at right. Now it's a little bit wet. So it's pumping together, we pulled a bunch of it up and we've been drawing it out so that we can use a more pottery clay type dirt in the CB press. Ok, here.

C

Are some before and after photos behind the greenhouse.

A

Live tracking action, we're scooping off the ground cover over the clay area that we want to use to press bricks, so we're scooping up all the organic matter and the rest of the hummus.

C

Okay, here we tilled some soil and we're drying about our cheeks a little too wet, so we're going to have a sample here then we're going to press with and Cebu should keep digging here for a big pile of dirt.

A

A

Here we have a disk ER and an older. Just growth got a few missing pieces here and there, but the main thing is: you can see: we've waiting it down with batteries. What we're trying to do is crush up this play. As you can see, the play is not getting first, very small, but it is doing something so marching is rolling over it a few times to see what else you can get out of it.

A

Keep trying different tools display is really ideal for making our bricks but we're having trouble getting it out ground we're still out here, working with the disco right now. What we've done has changed the angle here: we've got the front disc ER and the back disc and they're pointed forward and backward what we've done is adjust. The angle is about going to be even further back by pulling this armature for a.

A

Little bit better effect by breaking out the soil trying to do is get some air into it dry it out, as you can see, that is already happening right now,.

D

All right: here's, the tractor graveyard we've got a bucket we're going to rob off of this here. Machine start by pulling these pins connecting these hoses pins, dropping it in pieces and re rigging. It.

A

A

Oh it's Rollins day, two at factory and today we're putting up a hex eager for additional housing. This is a finished exterior here and, as you can see, it's got a door in it and the tent camps out inside and over here Martin is tenderizing. The ground.

A

Will level this roundup?

A

Okay, so this is uh this is Alex's hexayurt and we are doing our very best to the men, the soil and to figure out how to make it last as long as possible with materials that we have imported to the site. So what we're going to do is we're going to use this fly ash that is on the ground now, in order to disable s approval hole between the points worthy.

A

You know, we've got to seven foot four inch sides and we're gonna hope between them with the heavy hoe over here and we're gonna mix the flash into the ground, and then the rain is going to come down and harder for us. That's basically, a very simple method for stabilizing our foundation along the perimeter without being a lot of cash right.

D

Here's Alex wrapping it up just got a guide board sprinkles a little seam inches ash, which will then be lightly mixed, as you can see on some of these last ones.
