  An experimental investigation of possible anomalous heat production in a
special type of reactor tube named E-Cat HT is carried out. The reactor tube is
charged with a small amount of hydrogen loaded nickel powder plus some
additives. The reaction is primarily initiated by heat from resistor coils
inside the reactor tube. Measurement of the produced heat was performed with
high-resolution thermal imaging cameras, recording data every second from the
hot reactor tube. The measurements of electrical power input were performed
with a large bandwidth three-phase power analyzer. Data were collected in two
experimental runs lasting 96 and 116 hours, respectively. An anomalous heat
production was indicated in both experiments. The 116-hour experiment also
included a calibration of the experimental set-up without the active charge
present in the E-Cat HT. In this case, no extra heat was generated beyond the
expected heat from the electric input. Computed volumetric and gravimetric
energy densities were found to be far above those of any known chemical source.
Even by the most conservative assumptions as to the errors in the measurements,
the result is still one order of magnitude greater than conventional energy
sources.
