I checked out the globalcooling site.
the specs are:
"The new freezer will be capable of reaching temperatures below -95Â°C while drawing power from an automobile 12VDC cigarette lighter. Maximum power consumption is typically around 150-180Watts (comparable to headlights). The unit currently weighs in at less than 35lbs and has a cargo capacity of just under 1cu.ft.."
To me, this completes one piece of the grand puzzle.
This would be the device I would use to cool my main Stirling power producing engine, providing cold side engine cooling.
It is nice to see professionally engineered products coming to market.
The video is impressive.
