 I'm Corporal Ally Biteswinger, and I'm here with the gear. I'm Carmody, and he's going to be telling us a little bit about the lightning pack. Sir, do you mind if I actually put it on? Not at all. Well, a lightning pack is an electricity-generating backpack that makes carrying heavy loads easy for you. Because of movement, we can put a generator in there and collect that electricity and power batteries. We're hoping that they get fielded so Marines aren't burdened with having to carry as many batteries or re-supply so you can stay out in the field longer and be energy independent. Okay, let's show them how it looks. Okay, so right now you're walking with a locked pack. Okay, a locked pack. How much is in here? There are 60 pounds. That's 50% of my body weight. Right, and so you're accelerating that load every step, and the force on your joints is more than 60 pounds. A static load, if you're standing in one spot, would be 60 pounds. If you take a step, you're accelerating that load, so what you're feeling on your joints is more like 80, sometimes to 100 pounds. Wow. So right now I'd like you to press that button. All right, and you'll see that the pack is moving slightly, so it's making that easier for you to carry. And at the same time, you're probably generating between 7 to 10 watts of electricity. So that's the basic idea of a lightning pack. So when I'm walking, you know, the pack's moving up and down. And already I can feel the amount of effort that I'm putting into keeping the pack from moving around is less than I would if the pack was fixed to the frame. A couple of issues that I do have is that the frame's material seems a little weak. I would ask them to hopefully develop a patch with a stronger frame, a more robust frame, and then the actual, the noise generated by the bouncing motion is a little loud. And it's not ideal for, you know, controlling operations, so that's the only two problems I have. Other than that, it's a great pack. Awesome learning about these lightning packs here at Expo 14. The technology may not be perfect yet, but it's on its way. Thanks for watching, guys. We'll see you on the next episode of With the Gear.
