Soldiers of tomorrow are going to look much different. Sure, we are going to rely more on drones to fight wars. But soldiers could have much more advanced uniforms. The fact that the U.S. Army is developing wearable solar panels that will be integrated into solder uniforms shows where we are headed. Of course, there are other ways to generate energy. For instance, a knee brace that can capture kinetic energy of a moving soldier could also save lives. This all sounds familiar, doesn’t it?
