I’m interested in any processes that stop wars -without fighting, if possible.
One such approach is to deceive an enemy by using inflatable models of eg tanks.
Today’s invention is to equip real tanks with a rapidly inflatable outer skin, which makes them look like false, inflatable tanks.
This could be inflated using exhaust gas and would fool enough enemy reconnaisance observers to gain some kind of military advantage.
The material of this skin could be made to disguise eg the infra red signature of the tank within.
