You can imagine there being a machine that does all the cleaning, maintenance, etc. with a push of a button. It's just not as affordable as machines that burn 650 MB of audio data onto optical disks.
- malandrew 14y agoThe cost of copper is the reason they haven't dropped in price. Those devices need to very precisely control temperature at high pressures. They are also designed to be able to make many expressos in a row while simultaneously outputting steam for frothing milk. This requires a lot of copper not only for the assembly that the water goes through but for a high pressure reservoir, which also needs to be made from copper. The cost of the copper alone in some of those coffee makers is easily a couple hundred dollars. You also can't mix in another metal with a high specific head like aluminum in places to offset the cost because the presence of both copper and aluminum in the same water path will cause the two to react with one another.
