ABSTRACT
Following the work by several researchers we have
undertaken experiments with deuterium gas flowing
through the walls of a palladium tube. Tubes were
heated at various temperatures and either filled
with palladium powder or palladium compounds or
empty. Our mass flow calorimeter enables us to
accurately measure excess heat production. We
usually used palladium tubes 10 cm long, 2 mm
outer diameter with 200 µm thick walls, and
closed at one end. Deuterium gas is introduced in
the tube at various pressures, and temperatures
and diffuses out through the walls of the tube.
Thermal energy is determined by measuring inlet
and outlet temperatures of cooling water and its
mass flow. The energy yield of this calorimeter
is 95-98% depending on input power. Our best
result so far is an excess heat of 3 W with an
input power of 47 W using an oxidized palladium
tube filled with palladium powder. In addition to
these results we describe an experiment where
temperature oscillations have been measured,
indicating the importance of temperature in excess heat production.
