Coffee brewing continued...

After researching the Carnot cycle, thermodynamic equations, and looking at how coffee makers and espresso makers work, I've come to the conclusion that a simple heating element, one way valve tube and a pump would be adequate for my needs. However, can't afford to have a large tank of water. It's has to be mobile. So have to come up with concepts. Thinking of using the Coffee mug as part of the maker. Don't know how yet.

As an aside, the coffee pods are really expensive. It's a quarter a pod or more. So another short-term product could be a 'Make your own Pod'. Freedom to the consumer to choose which beans they want. Don't know much about how they make it now. May be economies of scale will prevent this product from becoming a home pod maker. For a hack job look here.
