Idea for making an insulative "vacuum core brick" from an evacuated jar, beer or wine bottle surrounded by a clay or waste plastic brick


 Idea for making an insulative "vacuum core brick" from an evacuated beer or wine bottle that is then surrounded by clay or plastic & then used as normal brick in construction

Following on from recent failed attempts with plastic bottles & vacuums 

Making an Insulated Eco Brick by Filling Empty Plastic Bottles with Rolled Cardboard or Plastic & Evacuating Air (VIB))  https://cabinznet.blogspot.com/2018/09/making-better-insulated-eco-brick-by.html

We have all seen bricks with big air holes in the middle, but ive not seen one with a vacuum inside. 
As a vacumm is a beter insulator that air, this may make a better brick & reuse the bottle without more energy input compared to if it was recycled.

However, I theorise that this may complicate the manufacturing process and only be suitable for handmade bricks 

Its assumed a beer & wine bottle will survive a vacumm as a jar did in this YT vid below .
if, so, wine & beer bottles can have air evacuated with the same process. 

A metal plug / heat resistant glue may need to be used instead of rubber & tape in the video.

This is so they survive the brick firing process 

If clay that dries in air is used, a plastic air filled bottle, reusing polystyrene waste or bubble wrap could be used, as there is no heat to melt the plastic   


Update 14-10-18 : There may be an issue with the screw top metal cap melting on a wine bottle

So if an access hole is left in side of the brick , so the bottle can be accessed after firing the clay brick body. A crew top & rubber valve cover can be screwd on & the air evacuated by brick being inserted into a vacuum chamber .

A peg on the ajoining brick could fill this hole when brick is laid & lock it into place for stability  .
See drawing below. Other pegs could be added . similar to toy building bricks

Alternatively, recycled plastic could be used like in the www.Preciousplastic.com method or perhaps air crete  / foam concrete bricks

The bottle could also be filled with earth to grow plants / veg out of,  to cool a buildings wall.

Alternatively, perhaps an air filtering mechanism could be inserted into the bottle / void  like a similar idea
