As in the electron's spin number!!?? Wow....
Such advance is the technology now... Beyond my comprehension XD
Awesome!!
That's just new research, whether it'll be viable as a commercial product remains to be seen.

It's no surprise (to me at least) that the corporation owning the most advance technology is none other than US Ministry of Defense.
As a comparison, while we're using flash drives up to capability of 32Gb now, it's been used in the Pentagon for few years back.

That's not right. Those flash drive you mentioned are designed and built by third party companies, certainly not owned by the US government. Just that they are still US company for obvious security reasons. I don't think US Ministry of Defense can afford to design and maintain their own technology for everything they use, but not marketing it. Maybe that's how it works in the past (pre-WWII). AFAIK Intel *IS* currently still the leader in CPU.

Last if not least, no, the military does no possess better than consumer electronics technology. They usually follow DOD MILSTD when it comes to stuff like temp curve stability, shock reliability and so on. Meaning that it's no more advanced than normal stuff we use, but instead of having a transistor in a single ceramic plastic case, military components come in metal canned LMC style casings. Resistors also come in fireproofed coating and the higher spec RNXX series. The Military emphasizes it's technology towards hardened reliability and the ability to operate in differing environments, often they will choose to use battle toughened last generation technology rather than latest generation stuff.

Yes fully agree with empire23. Military emphasis is always on reliability and security.
Note that even though we say their technology isn't much better than consumer electronics, "most" consumer stuff available to public are cheaper low tech stuffs. Those leading edge components are usually only use in industrial/enterprise area as they are too expensive and not marketable to mass consumer.


Added on October 12, 2009, 2:59 pmNewer technology in IC design (still in research) involves adding nanometer scale mechanical parts onto the silicon layer itself. Or was it using some other different material than silicon.
The technology to build tiny projectors (small enough to pack into a handphone) is already here. Couple that with those projected keyboard technology, someone can build an ultra tiny mobile computer already.

What's relevant is the amount of space and heat-sinking capability.

Big candles spread out in a house has the whole area to spread it's heat to. Small candles in a tiny box can heat up the tiny box faster. When it reaches critical temperature junction, thermal runaway could occur where higher temperature creates more resistance which in turns generates more heat and the tiny box meltdown soon after.
