Heating Coffee with Thermite!

Рет қаралды 224,159

Жыл бұрын

I had found a coffee company that used self-heating cans that use a thermite based reaction to warm the coffee. In this video I deconstruct a can to try and figure out how they work, as well as demonstrate the reaction involving the thermite inside a few different ways.
If you're interested in the engineering and chemistry behind the heater itself, I'd suggest reading the related patents (I just used google patent search for my own research), which are owned by HeatGen (which used to be called Heat Genie).

I was a crane operator in a foundry. We made Ductile Iron a few times a week. We used magnesium landscaping rocks (by the pallet) in a pre heated ladle. Then we would pour hot iron into the ladle. The flash from the interaction was the brightest thing I have ever witnessed in my life! I would close my eyes (while wearing shade 6 lenses) and could still see the flash. A very dangerous, but interesting job working in a foundry.

As I was deconstructing these, it was pretty apparent that they were designed with recycling in mind. The plastic components snapped off easily and the aluminum outer casing can easily be separated from the steel vessel that contains the silica thermite. Is it as easy to recycle as aluminum cans? I doubt it.

My first question is: why? Then I understand the convenience of it all, the interesting reaction, and the efficiency of it all. But, overheating coffee can burn it and ruin the flavor, especially if the coffee was premade, meaning it's a bit excessive for something such as this. And then I think how thermite could potentially be abused, and then I come to a unique and come to a completely reasonable question: why?
