So Rossi has gone from:
50 modules of 20 kW each
130 " 10 kW units
300 " 3 kW each
or more poetically stated, from bobcat, to tom-cat, to kitty-cat! :-)
So Steven Vincent Johnson's comment may prove insightful:
------------------------
"However, there is a subtle point that might have been overlooked here.
Consider the flip side. As
overall volume decreases excess surface area becomes LESS critical because what
volume exists can
more easily escape - since all "volume" is relatively close to a surface area.
Therefore... it IS
conceivable, from my POV, that Rossi's smaller e-kittins might be able to more
efficiently transfer
heat due to their inherent smaller volume as compared to the bigger sisters,
the e-cat."
------------------------
Perhaps this is why the "production" units have been shrinking in size and
power output... more
stability because heat exchanger has more room for excursions before going into
steam flashing mode
(unstable). Perhaps Rossi hasn't found a solution to the heat-exchanger issue
-- or more likely,
hasn't had time since he's wasted hundreds of hours politely answering blog
questions and doing
interviews! So right now the simple solution is e-kittens.
