basically some liquid evaporates in the hot area carrying away some heat, it then moves to a colder area and condenses, releases the heat, the liquid then travels back to the hot area and the cycle repeats. All very clever with no moving parts. However if the whole thing gets hot enough that the liquid doesn't condense then it stops working and just gets hotter and hotter until enough heat is removed and the liquid can condense again. Also if its not designed correctly so that the condensed liquid flows back into the hot area then it'll stop working (needs to work whichever way the vapour chamber is orientated, some experiments show the cards run cooler when mounted vertically rather than horizontally).
I'm no expert but it sounds like the former issue can be solved by setting the amount of liquid and the air pressure in the chamber so that the liquid always condenses over the desired temperature ranges (but you have to make sure it still evaporates at the lower end of your temperature range too). The latter issue is down to the design of the chamber itself and could be harder to fix.
Batteries and Hydrogen can't compete with hydrocarbons for energy density (yet or perhaps ever) so for fuelling planes where energy density is vital any reduced efficiency in energy capture will probably be outweighed by reduced energy use from not making the planes heavier
these aren't viruses they are trojan horses. there is a big difference, viruses are self propagating, trojan horses require the user to be fooled into installing them. the android trojan horses are quite limited at the moment due to android's security measures. they can only do things normal apps can do and wont be able to disrupt the phones operation (apart from maybe running up large data bills and using up credit)
