Excess energy from electrolysis is seldom over unity. Energy in

calorimeter with an error of about 25 mW. The cell was not designed
to maximize the efficiency. Therefore, the Power out/Power in ratio
has no meaning.
It has no meaning in the sense that it does not predict whether cold
fusion can be made practical. It tells us nothing about whether one
technique is more promising than another in the long term. However, a
high ratio does make the calorimetry easier. That is to say, it is
easier to measure 2.5 W with 5 W of electrolysis input than with 35 W
input. (The input power is sometimes called the "background," as in
"a 5 W background.") It resembles instrument noise in this respect,
except that electrolysis input is a deliberate and inescapable part
of the experiment. Gas loading and some other methods have no input
background power, so they are easier to confirm with a high s/n ratio.
