Thanks for the thoughts on CO2 filled bottles, Landon, but I'm not so worried about the thermal loss as I am about the mortar cracking and/or pulling away
from the bottles. Also, we're toying with the idea of plugging the ends of the bottles with silicone and a marble - would that work as well as capping or do you
think the CO2 needs to be under pressure?
As far as breaking the thermal bridge, Brian, my friend is wanting to make a bottle wall out of bottle "bricks" (two bottles cut in half and the cylindrical ends/bottoms taped together), but I thought if she used silicone to adhere the two bottle bottoms together that would create a break the thermal bridge between the inside and the
outside. However, I don't really know anything about the thermal properties of silicone, but the kitchen utensils we have sure doesn't seem to conduct any heat/cold
On another note...anyone know the crush strength of your basic wine bottle? I'm thinking I'll have to build a frame for the walls and roof...a friend of mine has a boat
load of old power line wooden poles that she and her husband got in trade for letting the power company use their property to store equipment during a rural
upgrade project. I'd rather not have the poles visible, but would REALLY not rather have the snow load on the roof crush the walls even more.
Here's the link to the picture that started my obsession, hope it inspires more insanity.
