Got tired of buying coffee makers that always burned out. A drip cone is the easiest to clean, never breaks.

Their layered construction can be described, from top to bottom, as follows:
1. A chamber for hot water. The top is open and has a lid. The bottom of the chamber has a number of very small holes, so that water will slowly drip through the bottom of the chamber.
2. A holder for coffee grounds. There are larger holes in this layer, so that water passes relatively quickly through the grounds during brewing.
3. A chamber to catch the brewed coffee.
They're still around, really popular in Europe at least (Bialetti is probably the best-known brand).
Quite hard not to over-extract the coffee, but still my go to when I need an industrial-scale caffeine hit...
The drip-o-lator style pots are NOT heated on the stove-top (a separate kettle is used), and the water moves from the top chamber, through the grounds, to the bottom chamber via gravity.
