Storage device writes information atom-by-atom

"In theory, this storage density would allow all books ever created by humans to be written on a single post stamp," said Dr Otte.

That's unreal. Too bad it has to be cold as hell to use. But it's a step forward in creating mass storage using this tech I guess.
 
Temperature of outer space is more than sufficient for a device using such technology (eg, -270 C).

Such a device might fit in well on a long term data collection space mission (eg, hundreds of years) or to something like making a super computer or AI brain in high orbit with comm links to earth or some other planet.

An aspect of space flight that is always needed is to reduce weight. In the early years of the lunar lander program, it used to be that a 300 pound oven was proposed idea to control the oscillator temperature of the lunar lander's radar altimeter frequency (ultimately critical to the landing descent). A friend I worked with, noticed that the characteristic curve of a certain type of transistor that could be used for oscillator control had varied characteristic across temperature, but also varied uniquely from transistor to transistor.. His proposed idea of finding two inverse matching transistor units and using them in a back-to-back cancellation that would result in a constant characteristic curve for output across temperature (ie, changes across temperature cancelled each other out) was rejected and even laughed at by colleagues/co-workers.

He bought a whole bushel basket of them and tested each manually till he found a suitable set (inverse match).

Yep, his idea ended up in the lunar lander replacing the 300 lb oven with just a set of hand select matching transistors !!!
