Coffee Ground Centrifuge

Good to the last 0.1mm drop

When I throw out wet coffee grounds, I feel gypped out of the last half cup of coffee. Proposed is a small centrifuge for kitchen or desktop use to squeeze the last drop of coffee out of the used grounds.

Does this thing look a bit overcomplicated? I think I can do better. [DIYMatt, Aug 26 2012]

       You need an espresso machine. The grounds are usually almost dry afterwards.

       This would gain a bun if it were a steampunk brass and mahogany contraption powered by a reciprocating steam engine driven.

       If you throw them out in a compost bin, you will gain another purpose for their use.

       Doesn't a french press do this to some extent already?   

       I suspect the key limitation would be filter cost, which would have to be more robust.

       No, it wouldn't.   

       If the centrifuge vessel is a narrow cone with the axis of the centrifuge normal to the wide end, then the liquid will be concentrated in the tip of the cone. When the valve is opened, the accumulated liquid will drain out under gravity into a filter.

       You could package the still slightly usable grounds under the name of Has Beans.

       //surely there's something to be said for adding a centrifuge to an espresso machine ?//   

       I've always thought the same thing, but I haven't posted it because it is at least half baked. Just now I found a patent for one which has, of course, never actually been produced. It is slightly different though. In fact I'm going to go post my idea now since it is very specific.   

       Edit: eh, nevermind.
