Sourced pictures · diagrams · visual references

Use public source images to clarify the concepts.

This gallery embeds public image/file URLs directly from source pages when feasible. No files are downloaded to this project. Each image includes a caption, source link, and a caution about how it should be interpreted.

Media gallery

Pictures and diagrams with source context.

These references support visual understanding of greenhouses, permaculture diagrams, Fresnel lenses, hempcrete, green roofs, and seagrass systems. They are educational references, not engineering approval or site-specific design proof.

Permaculture lecture diagram

A public-domain permaculture teaching diagram showing how design ideas can be mapped and taught visually.

Hempcrete wall
Renewable material assembly

Hempcrete wall

Hempcrete can provide insulating, vapor-open wall infill, but it is typically not the structural frame and must be protected from bulk water.

Green roof / sod roof reference
Living roof and habitat roof

Green roof / sod roof reference

A green roof reference for sod/habitat roof thinking; roof load, waterproofing, drainage, and root depth require professional review.

How to read images

A sourced picture is evidence of appearance, not proof of safety.

Photos can show precedents and materials. They cannot verify that a structure is safe, legal, ecological, or suitable for your region.

Picture ≠ blueprint

A greenhouse or hempcrete wall photo does not provide engineering details, structural sizing, fire rating, or code compliance.

Diagram ≠ permission

Seagrass and marine diagrams explain why sunlight matters, but water-city siting still requires environmental review and permits.

Source ≠ universal fit

A sourced example from one climate, culture, or legal setting may not apply to another region without local review.

Media rule

Use images to ask better questions.

Every sourced picture should lead to questions about scale, materials, water, light, fire, maintenance, consent, code, and ecological fit. The image starts the inquiry; it does not finish it.
