  In this paper, we introduce an estimate of the "commercial efficiency" of
Santilli's hadronic reactors of molecular type (Patented and International
Patents Pending) which convert a liquid feedstock (such as automotive
antifreeze and oil waste, city or farm liquid waste, crude oil, etc.) into the
clean burning magnegas plus heat acquired by the liquid feedstock. The
"commercial efficiency" is defined as the ratio between the total energy output
(energy in magnegas plus heat) and the electric energy used for its production,
while the "scientific efficiency" is the usual ratio between the total energy
output and the total energy input (the sum of the electric energy plus the
energy in the liquid feedstock as well as that in the carbon electrodes). A
primary purpose of this paper is to show that conventional thermochemistry does
indeed predict a commercial efficiency bigger than one, although their values
is considerably smaller than the actual efficiency measured in the reactors,
thus indicating the applicability of the covering hadronic chemistry from which
the reactors have received their name. We reach an upper limit of the
commercial efficiency of 3.11 for the use of pure water as feedstock, and of
3.11 to 7.5 for a mixture of ethyleneglicole and water. The study of the heat
produced by the reactions leads to large divergencies between the
thermochemical predictions and experimental data of at least a factor of three.
Such divergencies can only be explained with deviations from quantum chemistry
in favor of the covering hadronic chemistry. In particular, the indicated large
divergencies can only be explained with the assumption that the produced
combustible gas has the new non-valence chemical structure of Santilli
magnecules.
