[papercreters] Re: Solar Design T-square and clam shaped reflectors

My last message did not go through. Anyway, I added an animated gif at the bottom of the link at solar cooking. It is to help explain the procedure. I WILL be improving the animation, but it is good enough for now.
(I lost my gif animation software so i had to relearn it in different programs). There has been interest from India, from a top amateur American scientist and in this group so I am pleased so far.
Remember, it is a new class of solar cookers. So dive in and be a pioneer.

[papercreters] Re: Cement & Concrete FAQs (Frequently Asked Questions) Portland Cement Association (PCA)

Hi everyone ,i would try a hydrolic press it will have a pressure gage on it ,we did this and it started squising apart at 1200 psi.
A compressed block done in our press let go at 1630psi hope this helps.

[papercreters] Re: Solar Design T-square and clam shaped reflectors

In my case, I will be using cob, which is a mixture of straw, sand and clay. I will use that to make a mold, and I will use the mold as a form for a reflector.
A potential problem with the clam shaped reflectors is that they have to point at the sun (No problem there) and the clam shell has to line up with the sun's path. That part might be hard! It means putting it on an equatorial mount or adjusting it to point the same way as an equatorial mount. Perhaps easy, perhaps not.

[papercreters] Re: Solar Design T-square and clam shaped reflectors

Sorry for being so slow getting back. I thought I had animated gif software but I gave it away with an old scanner years ago. I ended up using an ancient microsoft animated gif software + the gimp "layers". I think the gimp works on its own but the old microsoft thing was useful for adjusting the timing.
(I just completed the first version a couple of hours ago. It will improve! and I will upload improved versions in the next couple of days). So lots of relearning, and searching for animated gif software!

On the link now, I have the animated gif at the end with the "procedure" for making a clay mold.
Basically you lay out the mirrors first. Adjusting them in sequence with the laser pointers. (You actually end up building up the secondary reflector at the same time as you build up the primary one) and you use the 2 lasers on each mirror in turn as you go.
Anyway, you probably need enough mirrors to do the secondary reflector part and still have enough mirrors for a couple of lines of the primary reflector.
When the entire reflector surface is made, you could take off the mirrors and smoothe off the surface. Then it can be used to make reflectors from corrugated plastic (cut to fit the shape), or fiberglass or whatever.
(I know it is a big project and I know it is a step into the unknown). A professor in India wants to know more too for an appropriate technology class that he teaches.
Anyway, thats it for now. Thanks for comments and if you do something, do not be afraid to add it to the solar cooking wiki. (There is a clam shell reflector page too).

[papercreters] Hi Folks

I'm new here. My boyfriend and I, after much research and consideration, have decided to build our house out of papercrete. I'm sooo excited! We live in deep east Tx is anyone close to the Palestine, Nacogdoches, Jacksonville area building with papercrete? I'd be interested in seeing and even helping a bit with the process. Any tips or advice is greatly appreciated.

Shelia/ Rusk, Tx

[papercreters] Resources needed for other Yahoo groups!

Hi, just found a lady that put us in touch with a great Solar cooking group after the post on the Clam Shell unit.
Is there a good Passive/solar group? Needing to find out how much solar power for different things to run. Books just don't cut it. Called a satelite internet company and they did not know.


Happy weekend, on to a source for shredded paper so am going to try a solar cooker with papercrete filler.

Thanks

Subject: [papercreters] Re: A papercrete shed at my school

 

Hello Annalis,

Just for fun (under the aternative building materials theme) you should also try light weight concrete using perlite (the white foam stuff in your potting soil). It sorta looks like rice crispies treats when mixed up but is solid when dry. Here's an easy formula is use:
1 pound perlite and between 2 and 3 pounds cement (2 pounds cement is about the mimiminum). Perlite is pretty light so this will make about two lunch pails full of mix! I buy cheap 4 for $1 plastic trays at the dollar stores for these experments.

Add about 2 1/2 pound water to the cement then JUST mix in the perlite. Don't mix too much or you'll break up the perlite.

It may be fun in class to try the different formulas for papercrete you find on this site and have the class analyse the results for hardness, final weight, cost per pound, drying time, spreadability (can it be spread like plaster?) ...

Have fun, Joel

I would think that uncompressed papercrete (the kind poured from a tow cart) would never be considered a solid (like concrete) because it would squish nearly flat long before it breaks. Maybe they would measure this squish.

As for measuring the pressure - it's easy enough to put a pressure gage on the jack and know exactly what pressure is being applied.

Hammer milled paper worked well for me when someone gave me some to try. I never used it straight but mixed it with cardboard, but I plan to do more with it when I start papercreting again. I say if you don't know if something will work just give it a try. Sometimes the new thing works better than the old one.

The hammer-milled paper is a by-product of a security firm destroying sensitive papers - like shreding, only much more intense!

What would do with 'paper flour'? It looks as light as flour too.

Would the paper lose it's insulation properties being this fine? I invision it would be like clay when mixed and hard and dense as concrete when dried.

I have made a simple tool for designing solar cooking dishes for unattended use. (Parabolic dishes must be attended so the poor cook ends up getting cooked too).
I tried making models with mylar but it did not work so good. Then I tried clay with little mirrors pressed into the wet mud and adjusted.
That worked like a charm.
Would any of you be willing to try it.
Basically the clam shaped reflectors are a whole new type of solar cooker. If you make one, it might be the first or among the first in the world of this type!
I think cob might be the best material to do a model.
Or if you are brave, you can go the whole hog and make a 1 meter fully operational clam shaped solar cook dish.
I will not have decent sun here till March. And frankly, the world needs this thing now.

[papercreters] Thanks Don for words of experience.

Thanks Don for your words of wisdom.

I think some us being new and not having the same conditions as others have to come up with some different solutions to our problems.

We so appreciate all the work, knowledge, time effort and energy that everyone has taken to teach us and share their experiences.

We have no roads where we are building, so would lose most of our tank of mix. So before we invest all the money time etc we have to weigh our options.

A stationary tow mixer is our only option if they are the best as far as load, strength and less breakdowns are concerned.

We have to have ours built as the distance, the materials and time are huge factors.

When the main guy works 12 hour days and is never home during day light hours and the city code says you can't do something like this, in your yard or driveway, then the next best option has to go into play.
Thanks to so many if you,
Our brains are still trying to soak it all in.

I like the solar cooker design setup. I certainly have a lot of solar energy here in SW Arizona. I've been very busy with my seasonal work here and have been just lurking for awhile but I've noticed a lot of newbies to the forum. One word I might put in is don't spend too much time reinventing the wheel. Many of the people on this forum have spent a lot of time with PC and you can learn a lot from them. Also there is no quick fix as far as getting paper, making pulp or putting up walls. If you're afraid to get a little dirt on your hands and to expend some physical energy in the process PC will probably not work well for you. And as for mixers, as Ron Richter says, once you start actually building, even a small structure, you will want more volume and that is where the tow mixer really shines. It takes a tremendous amount of force to pulp paper or cardboard and electric motors or small gas engines will not hold up nearly as well or give you the capacity that  the differential mixer , either towed or stationary will. They are really simple, sturdy and economical to build and use.

[papercreters] Hammer milled paper?

Joel, I like the idea of paper flour. What sort of business has that? (Is it a by-product?) DK

[papercreters] Fire retardant

I was watching an episode of holmes on homes and they were using a green insulation made from old blue jeans that was soaked in a boric acid solution then allowed to dry. They stated that no matter how many times it where to get wet then dry it would never mold and would not catch fire. That termites, mice, rats, roof rats ect. find it an unsuitable living environment and would not every live in this home.

This sounds like a win win for papercreters. Does anyone know or have an educated guess as to what the boric acid solution needs to be to be effective?

Re: [papercreters] Re: Just a little tidbit of information

Sounds good Bob.  I would make sure neither of the holders is sleepy or distractable.  It could get exciting otherwise. 
I too, am planning my second towmixer being a stationary one.  If set up right near (or in) the construction site then a trash pump can get it to the proper portion of the wall where it is needed.  My first one died near the end of last summer and over the Christmas break I disassembled it to find bearings shot and the bowl full of oil and water.  Must have had a leaky seal at the top of the column over the last 3 years of use.

Ron I just bought the Two Man Auger shown below. I'm going to mount it over a 200 Gal Water Tank, on two rails that will allow me to move the auger from side to side or lock in the center. I may use the auger and I may just install a shaft with a chopper blade on the bottom or a series of chopper blades up and down the shaft. I'm going to mount the tank on a two wheel trailer made from the front axle of a Old Dodge Pick-up truck. I'll be able to move it from place to place without the need to pull it around to pulp paper.  I probably will not mix papercrete in it at all, I'll just use it to pulp paper and cardboard, then dump or dip the pulp onto a screen and catch the water and reuse as much as possible. I'll then put the wet drained pulp into my mixer and add cement while mixing, after a time I'll add clay or clay and sand.

Re: [papercreters] Re: Just a little tidbit of information

This is a superb idea.  I can see this setup more friendly in some situations due to portability, but I especially like the idea about draining the wet pulp and mixing it with cement.  I am thinking this would allow for faster forms, which translates to being done more quickly with your project.

[papercreters] Re: Just a little tidbit of information

I don't have a towmixer (nor do I want one) but I can shred in all kinds of weather (12" snow on the ground comes to mind) any time of day or night, while I'm setting by the fireplace and watching TV. The below is an example of my shredded cardboard. A little bit of water and a short mix (say 2 min max) will produce an oatmeal looking pulp, just add cement, sand or clay or both and your good to go.

pulp after water added and before cement, sand and or clay.

[papercreters] What types of paper processing are required

Hello Group,

What types of processes paper work with papercrete? Shredded, torn, hammer milled, ...?

I was under the impression the paper had to be 'torn or pulverized', as done with a tow mixer or something like that, to get the benefit of strength of the fibers. If shredded paper works well then that opens up lots more opportunities for me (I can get shredded paper).

I also have a potential source for hammer milled paper but it looks like they worked it so hard it's now as fine as flour. Can that actually be any good for making lightweight insulating papercrete? Seems the crete would be pretty dense when dried.

I'd like to mold and pre-build the exterior papercrete panels for a geodesic dome.

This is a great group, Thanks in advance, Joel

Re: [papercreters] Just a little tidbit of information]

A problem with aggregate is clogging of sprayers. Some bales of shredded paper that I bought years ago came with shredded credit cards, cd's, window envelopes, overnight envelopes (tyvec), and a few beer bottles. All of those tend to clog sprayers.

I have thrown all sorts of stuff into my mixer, including bamboo. Styrofoam has to be pre shredded or it just tends to float around on top of the mix, even with lots of agitation. The bamboo was hard to break down. It did shred into long fibers that probably helped reinforce the papercrete, but never turned into anything like pulp.

If I ever get a chain flail built (as soon as it warms up some) then I'm going to be feeding it just about everything that will go down its throat. I don't intend to put too much filler junk into any one mixer load unless it is all good insulation. Junkcrete won't be used for spraying unless I can run it through a sorter/sizer first.

RE: [papercreters] Just a little tidbit of information

I hadn't thought of it before but I will now. Thanks.

PS I like it when  a bit of the original message (or better, the entire message) is left so I can follow the thread. I don't read each and every email I get but if I see something that catches my interest I will read it.
Having the original thought helps a lot. I know there are those who have the opposite feeling about this but this is my viewpoint.
Sincerely, Judith
