Future drone armies will grow in chemical vats

BAE Systems has lifted the lift on how future military drones could enter this world -- grown through labs packed full of chemical vats. Drones, also known as unmanned aerial vehicles (UAVs), are now commonly used for military purposes, from scouting operations to spying and surveillance. Their use can remove the need for human agents in the field and the market for this technology has barely been tapped. Drones are going to retain a strong position when it comes to military applications in the future, and as a result, scientists and engineers have been pondering the ways in which future UAVs could be manufactured -- and this includes being "grown" in labs en masse through chemical vats. It might sound like something out of Terminator, but BAE Systems said last week this could become a reality thanks to a new intelligent system called Chemputer.
