   I did a little looking around at eCat and found some conception pics
of what an eCat would look like for home application. I also found a
COOP of 6 listed.

   It appears that although the eCat is rated in kW, that this is kW of
heat.

   Anyone have any idea how eCat intends to use the heat generated?
Apparently this can be up to the melting point of nickel. But what
working fluid?

I'm guessing that you probably wouldn't want it as gamma rays. There may
be a potload of beta particles being produced inside the containment
vessel, which might allow eventual direct extraction of electrical
energy - but I wouldn't hold my breath waiting for that.

Heat is good.


For sake of accuracy, the E-Cat only /makes/ (not uses) heat. Rossi
started out focused on commercial power generation, and has become
distracted by the notion of selling brazillions of space heaters.

He may suffer from ADOS syndrome, like a lot of the rest of us.


If you can prevent the nickel from puddling, it can probably go a lot
higher than that - I'll hazard a guess that Rossi will aim for an
operating temperature safely below the boiling point of water.

Ahhh. And what fabulous space heaters they are. And domestic hot water.

I'm intrigued by the COP of 6. That implies to me that there is some
energy that must be expended to keep it running. I don't think this is
the heater, it seems to me that there must be some pump that pulses  the
hydrogen to create very high pressures. Otherwise this would be
completely self sustaining and have a COP closer to infinity.

I can see this as a sandwich of ultrasonic transducers creating high
pressure waves in the hydrogen gas. In fact there are lots of ways to
have local high pressure points in acoustic devices.

All this is mere conjecture.


That, is a new light on the subject!


I would think the fail safe for coolant loss is when the machine melts
into a puddle!

Thanks for not making me say it. :-)

Rossi claims to have run E-Cats in full self-sustaining mode, but has
had some (to my knowledge, unresolved) problems - including at least one
explosion. As I interpret what he had stability problems when he tried
to push outputs into the 10kW neighborhood.

Most likely, any consumer device will be operated in a
non-self-sustaining mode with pressure and temperature below what's
required for a fully self-sustaining LENR, but with sufficient energy
produced to provide an advantage over simple resistance heating.

I don't know enough about the effects of ultrasonic or microwave effects
on the reaction to sort the wheat from the chaff.


ADOS ::= Attention Deficit. Oooh ... Shiny!


I suspect that if the temperature in the containment vessel reaches the
melting point for nickel (1453C/2647F), failing safe won't really be
an issue.

I've spent the winter working (mostly) on software for a control system
to (I hope) safely test his claims and acquire enough data to make a
decent behavioral model. My goal is to produce a variable-power heat
source that operates in the 400C neighborhood to power an MHD
generator. If interested, you can see some of the not-so-technical info
by browsing the last two menu links (Generators & LENR) at the page below.
