Jeremy Whitsitt of the Defense Department shows CBS News' Mark Albert how the more efficient heater of the future compares to the flameless ration heater used in the field today.
It's cool until you're actually trying to rely on heating up an MRE. During basic, you're always eating it cold, and when you can actually use the heat pack, it works like 70% of the time lol.
They just fill the inside of the packet with an element/substance that makes a chemical reaction which emits heat, and it emits heat because the element/substance reacts to air or water depending on which MRE
Wow that was awkward when the dude pulled the one side off like a sissy and stripped it. Lol that poor guy that worked there is like thinking are u fucking kidding me. That was a good one. And that's either really shitty luck or a sign that the air activated one is really bad out the shoots
I'd stick with the water-activated warmer, unless its on specific environments. The water one is not shiny and not reflective to give away the soldiers position if they were behind enemy lines. The water one wastes less. Id wanna use the water one when it's cold as a hand warmer, too. The "new" one that is air activated also doesn't make sense. If it's air activated, it has to be extremely corrosive... Oxidation chemicals would ruin electronic components in a sealed enviroment in a sub/aircraft. Albeit a short term and small exposure, but if the whole crew has to use these for an extended period damage would be don
Zinc and potassium hydroxide. The energy released is 1.28 kcal per gram of zinc. The old one releases 5.92 kcal per gram of magnesium. Magnesium is also much cheaper to source and to process into a powder.
Jennifer, i would go with the old one. Hydrogen is the most abundant element in the universe. Hence why it's first on the periodic table. The plastic bag is recycable. The cardboard can biodegrade, or for soldiers be used for tinder (starting a fire). The one with the water pollutes less.
It's now 2020 and my coworker just gave me one of these to 'look at'. I don't think it's going to work for me and my partner. We bring real thermoses up the hiking trail and pour hot cocoa and hot soup that's hot and yummy. Yes the thermoses are weighty more than pouches but the results are worth every calorie/protein bite. I'll stick to them.
