UVM Bubble Insulated Greenhouse

So it appears that there is some tech dev to be done - appears to be a finicky system. It would be good to take their learnings and opensource them so others can build upon them. I'd like to hear what the issues were in detail and what their proposed plan is.

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. That indicates to me that their bubble layer thickness is about 4" (minute 0:47 in video) - I would go 12" at least to max out the 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 fora 10x improvement at least over a raw greenhouse - more like 95% to 100% for a properly designed system.
