Tech venture capitalist Adam Grosser worked with a thermodynamics team at Stanford, to build a thermos-sized device that contains a refrigerant that’s triggered when the device is heated and then left to cool. It acts like a powerful cold pack, turning anything from a jug to a hole in the ground into a twenty-four-hour minifridge. At roughly fifty dollars apiece, Grosser’s device could potentially bring people in the developing world high-maintenance medicines. Imagine how this same technology could be adapted for military use.
