Rope can be surprisingly strong and could quite possibly be stronger than a connection using nails or screws. The rope used for staw bales can take 200 - 400kg (440 - 880 pounds). As a loop has two sides it holds twice that.
So a few loops will easily exceed the strength of the beams.

A mixture of clay and sand (cob) works well as mortar – as long as water is kept away. I have build a small brick wall with it so far and it is quite solid.

EDIT: If your stone does not wick up the water, it may take some time for each layer to dry.

Could you arrange the linen singles so all have at least some part in focus?

The blue one looks nice with the wood of the shuttle!

I put up a Tent in the garden about a week ago to clean it and get rid of the smell of old plastic. The inner tent has a closed bottom with about 10cm wall around it. Today I was going to pack it up and discovered that the inner tent was full of dead, dried slugs.
I can only assume that they went inside because of the warmth and possibly darkness during the day and could not find their way out again.

This sounds like a good way to kill slugs to me. (A miniature tent should work too.)

I do like the idea, but there are a number of problems:
– Moisture can't be driven outside by heat. So you will need a dehumidifier in the space between the outside earth and the insulation.
– Light. Germany doesn't have a lot of light during winter. Underground this is even a bigger problem.
– Permissions… no idea. One reason for me not to stay in Germany.

Another vote for glass, especially if you take empty and cleaned bottles back.
How would you seal the glass bottles? Cork? Plastic plug?

I made a small experiment. Picture taken in direct sunlight (as probably obvious by the shadows) on a Nikon D7000 in RAW mode. ISO 100, Aperture F8.

The two attached Pictures are from the same RAW file. The first one uses sRGB, the second uses Adobe RGB colorspace.
I can try to take the same photograph with artificial light, once the sun has set.

EDIT: In a modern browser, they should look the same.

Sounds like a male to me.

Hello Christian,

being not much older than you, I decided to fully dive into permaculture about 2 years ago. That also resulted in the need to relocate, on which I am currently working on.

Am I making the right choice going back to school?

It depends.
If it is a good school, with good lecturers and mentors, that still works with the ideas of science, rather than money – yes.
Unfortunately, they are hard to find today. (I left the university due to that.)

My desire is to be a community developer, a sustainable designer, an innovator and entrepreneur. My greatest abilities in life have to do with fostering human connection; I excel at communicating, empathizing, advocating, and connecting individuals with other individuals who can "get sh!t done." I am just a super passionate middleman between the wants and needs of people and the systems they find themselves in.

Being someone who learns as much as he can – everywhere, I have found that it is useful to know all topics you are involved in, at least a little bit. Enough to determine if someone knows what they are doing, or if they just talk a lot. Then again, I do not excel at communication.

Is there a correlation between plant systems and human systems […]

Yes. The challenge is to find out what it is and how it works.

[…] and would a deeper understanding of those systems aid in the designing and implementing of more sustainable, efficient, proactive human systems in a climate of economic, social, political and environmental uncertainty?

Being that broad, the answer is unlikely to be "no".
However – knowledge itself doesn't result in good/bad results. How it is used is far more relevant. There is so much knowledge out there, that is ignored and denied and forgotten; scientists bad-mouthed, blackmailed or threatened.
We have to first create a space in which scientific work is possible. (This is actually what I am working towards.)
