Jack,
"Thanks to Brad for finding the comment from GoatGuy on Next Big
Future. I have had a chance to examine and think through the
arguments. I'm not an engineer, so maybe someone else can do a better
analysis. It seems like this explanation would work only if the
plumbing connected to the water tanks in certain ways (e.g., outlets
connecting to the central reservoir near the top). If they connected on
the bottom of the tanks, there would be mixing and prevention of air
pockets."
There are several simply ways of proving the E-Cat works. Of course you
can cheat with any of them if you set your mind to it. If you can't
believe the experimenter you have to have a competent observer to check
for cheating. That is the problem here with those that don't trust
Rossi. That is why an independent tester like an ERV is valuable.
I don't think GoatGuy brought anything new to the party.
