will the guides be written in a wikipedia like fasion where anyone can edit them and add to them?

Module - Overall CEB Press: What are the compressive strength & modulus of rupture for the bricks?

Tue, 19 Mar 2019 16:49:25 -0700

What are the nominal compressive strength & modulus of rupture for the bricks as per the international building code(IBC2018)?

You appear to be using 555PSI to create them but were you able to test their strength as individual masonry units? Naturally this will vary depending on the composition of the earth used but do you have any typical numbers? I’m curious about passing inspection.

LifeTrac: What was the justification for using 4x4x0.25 square tube?

Sat, 16 Mar 2019 22:57:15 -0700

I can’t find any documentation about what the expected loads and capacities of the LifeTrac. Can you explain or direct me to documentation of the expectations of the LifeTrac? Thank you.

LifeTrac: Status of this project

Mon, 08 Oct 2018 07:48:14 -0700

Hi guys,

I’m very impressed with this project.

Can you tell me why there seems to have been little activity on the LifeTrac project in the last 4-5 years? Have you just moved your attention to the other projects?

Also I think it would be great if there was more footage of the LifeTrac 6, especially doing actual work. From what I can find there’s flashes of it here and there but mostly of the older models.

Also have you thought about opening a Liberapay account?

Regards,

Mark

Trencher - Modules: What are the practical limitations?

Tue, 17 Jul 2018 12:39:59 -0700

I noticed that the disc diameter is 6'. This would suggest that the maximum depth of trench is likely less than 3' (ie, radius of disk, minus limits imposed by operating mechanism, plus depth increase due to length of bits). The frostline where I'm located (Canada, near Ottawa) is about 3.5'. To safely ensure that I never have frozen water lines, I'd need a depth of 4' (the depth that all water lines must be run in my area), which would suggest that I would require a 9'-10' disk. I'm thinking that this would be rather impractical.

Was there a consideration of using a chain-mounted bit system more like commercial units use? Why, other than simplicity, was a disc chosen as the trench blade?

Lifetrac 6 - Development: Lower profile Lifetrac with trailer function

Wed, 30 May 2018 09:27:02 -0700

I would like to have a tractor like the lifetrack 6 but that is lower profile and is longer. I want it to not only serve the function of loading, digging, etc but I want it to be a trailer as well. You can think of it as a powered trailer with a frontloader and backhoe on it. Do you have a machine like this - or any plans to modify this one? I will be purchasing land in the desert soon. the land is not very level but I will need to haul material around on it for construction sake, as well as to haul water around to irrigate. I am not crazy about the idea of having a tractor and a trailer - would make it easier to control if they were one and the same. This LIfetrac tractor/trailer must be capable of carrying 10,000 pounds on it - the weight is over 1,000 gallons of water.

CEB Press: The discussion forum appears to be defunct.

Thu, 24 May 2018 15:14:27 -0700

Is there a new link to a forum where we can discuss our challenges in assembling and operating the Liberator CEB machine?

LifeTrac 7 Overall Development: How is it going?

Sat, 17 Feb 2018 13:08:46 -0700

Hi! I met a farmer today that needs a tractor. How is this one going?

On the other hand, do you have anything that can cut down watermelon harvesting time by 50%?

Thanks!

CEB Press - Development: Software used for the hydraulic draw?

Fri, 14 Apr 2017 05:24:48 -0700

Hi,

I'm a student of the University of Trento (Italy) and I have to make a pneumatic project for a course. I would like to propose yours because I think that is a fantastic idea. The problem is that I have to redraw the pneumatic circuit in another way rather than you. Can I ask you please which software do you use?

Thank you.

PowerCube: Access to Design Drawings?

Sat, 04 Feb 2017 12:33:42 -0700

How can I get access to the design drawings for the Power Cube? I am considering building one.

LifeTrac: Tubing dimensions and wall thickness

Tue, 17 Jan 2017 06:26:17 -0700

Is that 4 inch steel square tubing with half inch clearance holes on 3 inch centers? Is the wall thickness 1/4 inch or just 1/8 inch? I am not an ME, so knowing the materials you found strong enough is good information for me.

Foundation Module: Foundation depth relative to frost line

Wed, 28 Dec 2016 20:33:32 -0700

It looks like you are pouring footings on grade. What do the local codes say about the frost line depth? I live in the desert and our line is at 18" below grade.

Microhouse 3: Is there any guide or videos for building any of the microhouses?

I would like to learn how to build any of these houses.

MicroHouse 4 Overall Development: Arched soil roof? Earthen plaster?

Sun, 03 Jul 2016 11:03:07 -0700

First off I need to State I am a huge fan of what you're doing!!!! Awesome & inspiring!!!! Have you considered not using wood or sealing your Wall Systems?

These structures will last 1000 years or more without wood. Using Earthen plasters inside and out will allow the structure to provide evaporative cooling inside on hot days as well as provide warmth and slight humidity on dry cold days.

You guys give me hope for this world!!!

Keep goin!!!!!!!

Composting Toilet: How can we make humanure composting feasible in an urban setting?

Sun, 26 Jun 2016 13:24:17 -0700

Do designs already exist for a compost toilet small enough to fit into a studio apartment lifestyle? If so, how exhaustive are they and at what point does the compost return to soil? Or, what other opportunities are available in an urban setting to make better use of nutrient that would rather be lost down sinks, garbage disposals, tubs, and toilets?

Frame: Navigation of website is difficult

Wed, 22 Jun 2016 17:09:03 -0700

These projects are loaded with potential, but finding the actual blueprints are difficult.

It would be better, for me anyway, if each machine blue print package could be available on DVD with a full hard copy of the prints. I would gladly pay for this.

Thanks, Dan Katz

I think I've got it now. Marcin answered my questions. Thanks
