a) Why no bottom heat exchanger fins?
Rossi said a long time ago that the Gamma thermalization was partly
in the lead shielding. In the original tubular ecats the lead was
probably in contact with the copper pipe. I would expect the bottom
lead to need fins. (I'd put them back, with a "?")

says :
The current design of the reactor is a small rectangular plate 20cm x
20cm with a thickness of about 4cm (external dimensions of reactor).
The fuel, Nickel of very fine granularity + Hydrogen + catalyst, is
placed in a thin layer at the center of the reactor core. The reactor
is located at the bottom of a steel box (the outer hull of the E-Cat
is currently at a size that can easily fit on a small table) and
directly attached to the reactor is cooling elements in the form of
wings. These wings are crucial as they transmit the heat generated in
the reactor to the surrounding water.
There is a cold water inlet into the steel box and a warm water
outlet. As the cold water flows past the reactor, the cooling
elements will heat it up and the flux of the water (e.g. liters/h)
dictates the difference between in and out temperature. In this way
hot water or steam can be produced.
SO : no bottom fins, no water flow through three cores in series.
I was a bit confused by "cooling elements" ... they cool the reactor
and heat the water.
