Isn't this basically how those single-use hand warmers work? Fine iron powder reacts with air/moisture? Sounds pretty useless given that a) Elemental iron does

Isn't this basically how those single-use hand warmers work? Fine iron powder reacts with air/moisture?
Sounds pretty useless given that a) Elemental iron does not occur naturally on earth b) It requires a lot of energy, usually fossil fuels to make it.
- Markxr 6y agoMaybe they can cut out the middle-man and just burn coke, which does not need to be stored in a sealed container
- imtringued 6y agoWhich middleman? The suggested method of obtaining pure iron powder involves electrolysis of oxidized iron powder. I don't even see where you could insert coke into this process.
- Markxr 6y agoThe process for actually making iron, rather than the one they've imagined, involves smelting with coke. I'm pretty sure that electrolysing iron oxide is not a thing that's done on an industrial scale.
- regularfry 6y agoElemental iron does occur naturally in scrapyards, and the process is a cycle.
