The MD mentions in this video they cryovacc prototype is currently being built. Would like to see some data and peer reviewed studies on the performance once it's ready. Renergen state "the operating cost of the case should be under US$3 per month for each dose." Given they claim it can operate for 30 days without power and handling there would be other cost benefits and savings.

UPS is Pfizer's main transport and they use dry ice. Each Pfizer location requires around 40 pounds of dry ice a day. Dry ice is $1-3/Lb. Dry ice will sublimate at a rate of 1% per hour in a typical insulated container. 100Lbs of frozen food requires up to 100Lbs of dry ice to keep it at temperature for 2 days. If Renergen can keep vaccines at stable temperature for 30 days at a cost of $3 per dose this is revolutionary. I know a little about this area.
