UVM Bubble Insulated Greenhouse

An excellent report on the results of Bubble Insulation System for greenhouses from U. Vermont, USA.

Commentary on results: It appears that there is some tech development to be done - appears to be a finicky system. It would be good to take their learnings and opensource them fully so others can build upon them. I'd like to hear in detail - what were the issues and what is their proposed plan for addressing them.

Also, a 40% reduction in heating requirement is not particularly impressive for the effort used - using about half the heat over a regular greenhouse. That is comparable to a thermal curtain - their 30% improvement over a thermal curtain seems not particularly impressive, either. The video indicates a bubble layer thickness of about 4" (minute 0:47 in video) - I would go for 12" to show impressive insulation properties - perhaps get energy savings more like 95% than 40% - meaning that you hardly have to heat at all - or could heat with as little as a small electric heater if needed. We should be looking for at least 10x improvement over a raw greenhouse.

The 12" cavity would work with our sandwich of 2 6" wide modular roof panels like we used in MicroHouse 4.
