It's been around for 50 years
It's called amateur radio.
After the Sumatra-Andaman quake and the resultant tsunami the only way to pass messages for days, if not a week or more to many islands (which had in some cases been submereged totally, albeit breifly) was amateur radio.
Digital modes such as PSK31 are incredibly robust, use almost no bandwitdh (about 60Hz) and need almost no power. 5 watts is sufficient with a simple wire aerial to get error free copy from the UK to Ukraine for example, as I was doing last night.
But hey, it's not something you can easily chuck money at is it a solved problem so let's ignore that part.
Not everyone is that daft
Natrium hydroxide above would be better served learning about the spectrum. The amateur allocation - far from being bloated is quite small in the microwave regions where antenna sizes are sensible enough to be use for wireless. Yes you could plunder the shortwave allocations - but who wants a wifi antenna 20m long attached to their netbook?
Proper dust bunnies
Back when the motor industry was a four letter word in Essex (work it out) I recieved a Tecra with an acrid smell and a note saying "leaky battery?"
Duly parcelled off to the PFY it made a sparky noise on startup and smelt acrid, so back to Toshiba it went. They sent it back to us saying it wasnt leaky batteries and we had spilled something on it.
While the lean green keen PFY against the advise of the rest of the office stripped it to find a find a milky substance inside, I phoned the listed owner in the ticket to find that it was a bunny issue - his daughters house rabbit was fond of sitting on it, and presumably widdling in it.
Cue the real meaning of dust bunnies, and a PFY who developed an OCD handwashing disorder for the next few weeks.
Phones down? GLK london calling....
Remember that story about the Home Hub networks and amateur radio? Guess what sort of people can still talk over the country, and indeed internationally even when all the phones go down for whatever reason.... Take me about ten minutes to set up a worldwide capable station from scratch capabale of phone, data, and TV transmission.
Megaphone for like obvious reasons
It was at CERN that the WWW was created - that medium that you are using now to spread your own personal vendetta.
Faraday asked "What use is an unborn child?" This research has no immediate use. It's what it may grow into that is excitiing. Maybe a way of cold fusion? Maybe showing how to make submoleculer structures to store higher data densities? Perhaps a tigher noninvasive imaging beam or maybe advanced radiotherpy beams.
Who knows. You certainly don't and neither do the scientists doing the research but that's *why*.
