Here’s one way of sending a message the NSA can’t hear. In research that would have fulfilled so many stereotypes if it had been Russian, but which was actually done by a Canadian-UK team, scientists have shown they can spray vodka into the air and pick up the resulting binary code 4m away.
The idea is communication when radios fail, or aren’t possible. Like robots moving through confined spaces, where one can leave a “vodka bar code” for the following robot to pick up.
More on NSA/Quantum: There was one more document on the NSA’s quantum computing research released, which I missed. Based on this one, it would in fact appear that the NSA isn’t any further ahead on QC research than the general scientific community. (And that they weren’t bamboozling Congress.) I’m still kind of scratching my head, partly because they don’t seem to consider it all that secret. http://cryptome.org/2014/01/nsa-quantum-computer-2.pdf
Speaking of head-scratchers. Former Canadian minister of defence says UFOs are real. When I talk about ‘exotic attacks’ this isn’t what I mean…! Anyone got some extraordinary proof to back up the extraordinary claims?
I don’t mean stories of “yo the greys took me to alpha centauri, man.” I mean more like “here’s a video tour of the engine room, and an interview with Captain Fliadtg.” http://rt.com/shows/sophieco/%D1%81anada-minister-defense-ufo-959/
“Academics have developed a method for delivering text messages through vodka spritzed into the air.
Unlike conventional vodka-powered texts – which involve lemon drops, smartphones and lingering regret – this new experimental system uses the alcohol itself as the medium for delivery.[…]
According to the eggheads, the sender sprays vodka at set intervals and concentrations to mimic a binary pattern of 1s and 0s. A second unit, placed four metres away in laboratory tests, then analyses the concentrations of the alcohol in the air and converts the data into digital code and characters, effectively receiving the transmitted missive.
“Our goal was to show that we could use chemical signals to transfer info instead of radio,” said Nariman Farsad, doctoral candidate at York’s Lassonde School of Engineering, who headed up the effort.
“We wanted to build a simple setup that other researchers could also use.”
In controlled tests using the aid of a small fan, the trio were able to successfully transmit the text message “O CANADA” between two units. The team likened it to the pheromone and urine marking systems many animals species use to communicate over long distances.
The academics believe that such platforms can be implemented as backup measures should conventional wireless communications be disabled in emergency situations or in confined spaces where multiple robotic units are operating in sync.
“One robot could drive along and leave a pattern of chemical dots,” explained Professor Eckford.
“The second robot drives over that strip reads the dots and it would work like a chemical bar code.””
