I'm not sure if I'm right because I only see it conceptually but a aquafier layer of crushed glass might be the solution to soil erosion on the Great Plains. Buried a foot under the present soil it would hold moisture and roots without adding salinity. ?

We wrapped up the ATC here at my place, and we have one solution that is rock solid and another solution that is going to get wrapped up in the next week or two.

The solution that worked was to be able to put a tray of broken glass into a rocket mass heater:




The second effort is to use a fresnel lens to melt glass.   (this might end up being called "fresnel lense glass melter (flegm)").

A stepping stone:




The new version is under construction:




Go Josiah Go!

On Monday, visiting a neighborhood in Missoula, Paul and I ran across this amazing gabion-style fence with glass bottles.

Then there is using old bottles as insulation in a concrete sub floor. It's an old technique but it seems to work well.



woah! this seems cool! so it is the air in the jars that acts as insulation?

Yes, it is. Insulation is actually a series of heat exchanges.  Hot air meets cold surface, some of the heat bleeds off.  Next air pocket, more heat loss.  That's why goose down is such a great insulator: millions of tiny "beer bottles" to trap the heat.  This bottle thing is even used by many to insulate the base of cob pizza ovens. I used wine bottles at the base of my oven which got to 900 degrees but i could put my hand on the base. However, it is not the best insulator to use because it only presents one heat exchange. So i worked straw and such into the cob to create more air pockets.  It's why insulated sleep pads for backpacking are so much better R value than non-insulated. This bottle floor is more like the latter. Still inspiring though.
