Hate to be the bearer of bad news, but I think somewhere in the Snowden documents it says the NSA has the ability to send/receive data from airgapped machines. There might be a greater than 0% chance that isn't true though, to discourage people from doing it.
The issue with a ton of these "they can do X" is that they require near complete control of the machine in question anyway to perform. Like the proven idea that noise (the stuff you hear, not random entropy) from a CPU can be used to figure out the encryption keys used for encryption. The issue is the sheer amount of control necessary to perform such an action. Now. None of the above is to say the NSA couldn't easily take control of your computer. They could, easily. But you aren't worth it so they don't. Intel has had many backdoors found. A privilege level higher than ring 0 was found etc. The same things exist in AMD so don't feel safe because you're an AMDbro versus an intelbro.
e: Also Snowden was a limited hangout (controlled, intentional "leak") to prevent the goyim from looking for more kikery.
But now they can do so openly. No more needing denial.
If it's truly airgapped then data can't be sent, by definition. There are so many channels for covert transmission: blinking LEDs, power supply noise due to changing load, speakers in PC, RF emissions due to bus activity, embedded cell radios in chips, bluetooth and WiFi adapters.
bluetooth.. and that little chip people on poal think isnt important that freescale worked on, and then a plane of the developers and 4 patent holders all died (the malyasian aircraft that went missing) leaving one patent holder who is the richest person in the world i believe.
there really is no solution other than to buy amatuerradio and then do packet swtching with non software defined radio with a computer and peripherals in a faraday cage.
photolithography at home will be the technological revolution because then, only then, can you have badass robots that talk and do dishes because the hardware and software can be designed together. in doing so a very fast, more human like, computer is made with specialized organs that work inately. instead of a harddrive and mother board it would be more like a big chip with layers encased with all of that built like a bugati veyron under the hood; a computer aided render very jumbled looking.
