The idea of a vacuum coffee maker is to heat water in the lower vessel of the brewer until the expansion forces the water through a narrow tube into an upper vessel that contains the coffee grounds. When the lower vessel has more or less emptied itself and enough time has elapsed the heat is removed and the resulting vacuum will draw the brewed beverage through a strainer back into the lower chamber from which it can be stored. The device must usually be taken apart to pour into a mug. An early variation of this principle is called balance siphon. This variation has the two chambers arranged side by side on a balance like device with a counterweight attached to the heated chamber.
It has been a long time since I have used a manual drip coffee maker but I do have limited experience with them. I began many years ago to use the single cup model as I was the only java drinker in the household at the time. If you can boil water and measure a tablespoon full of coffee the hard part is done one can easily make a great cup using the manual drip method and is certainly cost effective as they are generally inexpensive. The larger styles can brew 8- 10 cups at a time.
