Someone decided to be clever and actually put technology to good use (as opposed to pouring endless amounts of money into developing bigger and bigger TVs), having developed a refrigerator of sorts that doesn’t require any electricity to operate. A team at Stanford, funded by a VC dude by the name of Adam Grosser, came up with a device that essentially works like a big hand warmer, but in reverse. As the device heats—put it over a fire, maybe—up it triggers some sort of coolant.
Conceivably, you could store medicine and other fragile, life-improving odds and ends in there.
