e-catworld has this update.
UPDATE: Rossi reports that one of the testers told him: ” ” What we have
seen is too important, must absolutely be published”. Also, in reference
to the new design of the hot cat, he states: “Basically, we have no more
a reactor or a cluster of reactors, but each reactor is coupled with an
activator: let’s make this model: the activator is the Mouse, which
makes the Cat run. The Mouse has his own COP which is more than 1, the
Cat is a surprise.”
I speculate the CAT is heated by the "activator" and so possibly doesn't
require further heat input.
