The foam liner behind the cans expanded enough to pop the silicone seal out at the bottom and middle so it's no longer sealed.The white vinyl hoses cracked and are unable to move air anymore. I'm thinking of a second attempt with the same frame using copper pipe embedded in cement as a thermal mass, with no glass involved. Thinking it through right now.

the water is the most efficient at retaining heat, while the air heats up fast and cools down even faster. the sand is about right in the middle.

I over lapped the glass in the middle about an inch.

This one lets air travel up through the cans so it can pick up heat, There is no problem harvesting the heat if its sunny so I don't think having thermal mass would be useful as it would still cool off within a half hour.

It went together fast over two days, so no real detailed construction pic's. Added a oven probe type thermometer to the top right side later on. Will post a video after snow fly's.
The outside ... By: wuberman. on 13 Oct 08, 04:20:15 The outside temperature was about 25 degrees Celsius. It needs the fan running when facing the sun or the insulation gets to hot and expands. It holds at around 100 degrees with large air flow through it.
