Mocha is generally confused with espresso, and the difference is subtle...
Where as espresso requires a rather high pressure (130 psi) mocha is
extracted more slowly and with a smaller pressure, the pressure produced by
boiling water itself. (Espresso machines require pump or piston action)

The process is rather simple, water is boiled in an enclosure, when it
reaches a pressure of 5,8-6,9 psi, it is released through a valve, allowing
it to flow through the coffe pod. This extraction takes around 60 seconds.
Original mocha pots come in two versions, the most basic ones, including the
original octagonal, as designed by Alfonso Bialetti in 1933 are for use on
stove tops, and starts from 10 USD and up (most expensive models includes
designer ones by Allessi and are in the 100+ USD segment) - if you want one
that you can use without putting it on a heating element of some kind (gas,
kerosene, electrical, whatever) - you can go for one of the units with an
integrated heating element - those ship for around 30 USD and up.

Coffee grind has to be slightly fine - somewhere between filter coffee
(medium) and espresso machine coffee (super-fine) - if you have your own
grinder, adjust so an extraction takes one minute with a full pot (if too
fast, grind finer - if too slow make your grind slightly coarser)

As with any coffee ...the machine itself is slightly forgiving about most
factors, but what really matters is the quality of coffee and the grind
size. So make sure you spend your bucks on freshly roasted coffee ground to
the right size - and then you can produce the superb mochas with a 10$ pot!
