Barium would not last long in the atmoshphere as barium. It is an incredibly reactive metal that would form barium oxide before it left the plane. The reaction is highly exothermic, the plane would leave a big blue flame accross the sky. Very beautiful but not very subtle. Aluminium could be dropped from a plane more subtly though I cant see how this would affect storms putting a higly diffuse layer of metal into the atmosphere is not going to significantly affect the charge distribution in the atomsphere. To generate a storm requries huge amoutns of energy, this naturally comes from moving air masses on a global scale, a few tonnes of shredded bacofoil wont have any real affect. There maybe something but nothing ive read here stands up to any serious scrutiny.
While I think about it is aluminium nitirite really that rare? Given that almuinium is the most common metal in the Earths crust and biological processes generate lots of nitrogen radicals im suprised its rare. Chemistry isnt my area so im not saying thats wrong but im a little suprised.
aluminum nitrite isn't common in earth's crust, neither is aluminum chloride (Al(NO2)3 + NH4Cl AlCl3 + N2 + H2O chem is my area, and last time I checked, heatsink compounds like aluminum nitrite aren't commonly found in dirt.
It doesnt suprise me that aluminium chloride is rare, but weathered aluminium filtering through the soil, it suprises me that AlNX compunds are rare. I know that aluminium in rivers can be a drinking water issue as its so common in rocks. Either way if this does exist i cant see it affecting the weather mayeb modyfying whats there. If you covered the sky with serious amounts of material (like a fleet of planes with enough material to darken the sky) may get cold up there and create condensaton centres for water, if you tried you might be able to make one of those nice fluffy cumulus clouds, though this would need to be dropped far to low to be mistaken for a contrail. If this does happen I think its far more likely to be trying to create a very disperse layer on the ground. Perhaps its a very low activity isotope and their tracking us by looking for the radiation from satellites. This i call conspiracy theorist baiting.
the "weather warefare" theory may seem a bit far-fetched, but so was cloning about a decade ago; don't underestimate technology, especially when CIA has access to it. remember SDI? (Strategic Defense Initiative) people called that far-fetched too. It's well documented now.
I have no problem with there being technologies I dont know about but assuming that CIA scientists did learnt similar principles to the rest of us at uni then you come up against conservation of energy. You cannot create a storm with out energy, even a fairly small storm requires a huge amount of energy to form. I have no doubt that putting large amounts (I dont know what consitutes large amount in this case but I think can assume orders of magnitude more than a plane can carry) of conduting material in a thunderstorm would affect charge distribution enough to have a measureable effect. Im not sure what it would do but you can at least picture how something might happen. Though its hard to see how aluminium can supply the energy necesary to counter act the energy supplied by the sun. As I say the best I can come up with is that epic amounts of material may cause cloud formation if there is already water and favourable temperature conditions. Though at 30'000 feet where temperatures are far below 0 it seems far more likely that it would just get dispersed by the wind, unless theres an RFID tag in it all and its a CIA version of that fete game where you buy a balloon and theres a prize for which goes furthest.
yeah, so is "intelligence", in many senses of the word (including its relevance to people who play devil's advocate with a proven idiot)
I still like the idea of trailing Barium for an aircraft, be great on Guy Fawkes night, or some other generic firework occasion. SDI was more technologically challenging than trying to defy physics. It relied on the X-ray laser, which is one of my all time favorite ideas. For the non-physicists, a laser gets harder to make as the frequency gets higher. So a micrwave laser is very easy to make, an optical laser is hard but doable and very worth while. An X-ray laser, however is incredibly hard however if you explode a nuclear weapon around iron rods then the rod will act as an x-ray laser cavity until of course the whole thing is obliterated a microsecond later. Ive always though that its a great deomonstration of what happens when you give defense scientists a blank, signed cheque.
