I had to search... I think those are what we call percolator coffee makers. As I recall they make surprisingly good coffee as long as you don't leave them on the heat too long.I have a almost-unplugged setup: A very good manual grinder (Comandante) and a couple of sizes of old restored Bialletti stainless stovetop models. The older ones are way better made, and can be found with defective gaskets or burnt handles, ready for a refurb, often for free.
I have a manual coffee grinder screwed to the wall next to my sink. I used it during the peak of my coffee tomfoolery. It doesn't take much effort but does take time that is at a premium in the morningThe Comandante is one of very few manual grinders that can make the full spectrum (french to turkish) with good precision and a reasonable effort.
likeWith the Bialettis, it's imperative to not overheat the can. On my stove, it's half power on the smallest burner. The pressure and temperature is controlled by the power under it, the grind and how much you pack in there. I usually do a couple of test shots when trying a new bean.
Talking about obscure coffee makers for years (decades?) I used a vacuum coffee maker.I find this setup super for a somewhat portable lifestyle, it takes up very little space in a small kitchen and makes great coffee on the boat or in the summerhouse or in the back woods...
Cheers!

PS filtered water is the best.
You put coffee grounds in the top, water in the bottom. Boiling the water drives it up into the top to mix with the grounds. Then it is removed from the heat. As the bottom cools it creates a vacuum and sucks the coffee back down through a cloth filter, into the bottom. This technique makes excellent coffee, but the glass parts can be fragile. I suspect mine broke, I recall using it back in the 70s-80s.
