Physicist Claims First Real Demonstration of Cold FusionIsn't deuterium a little hard to come by?

On May 22, researchers at Osaka University presented the first
demonstration of cold fusion since an unsuccessful attempt in 1989
that has clouded the field to this day.
To many people, cold fusion sounds too good to be true. The idea is
that, by creating nuclear fusion at room temperature, researchers can
generate a nearly unlimited source of power that uses water as fuel
and produces almost zero waste. Essentially, cold fusion would make
oil obsolete.
However, many experts debate whether money should be spent on cold
fusion research or applied to more realistic alternative energy
solutions. For decades, researchers around the world have been simply
trying to show that cold fusion is indeed possible, but they´ve yet to
take that important first step.
Now, esteemed Physics Professor Yoshiaki Arata of Osaka University in
Japan claims to have made the first successful demonstration of cold
fusion. Last Thursday, May 22, Arata and his colleague Yue-Chang Zhang
of Shianghai Jiotong University presented the cold fusion
demonstration to 60 onlookers, including other physicists, as well as
reporters from six major newspapers and two TV studios. If Arata and
Zhang´s demonstration is real, it could lead to a future of new,
clean, and cheap energy generation.
In their experiment, the physicists forced deuterium gas into a cell
containing a mixture of palladium and zirconium oxide, which absorbed
the deuterium to produce a dense "pynco" deuterium. In this dense
state, the deuterium nuclei from different atoms were so close
together that they fused to produce helium nuclei.
Evidence for the occurrence of this fusion came from measuring the
temperature inside the cell. When Arata first injected the deuterium
gas, the temperature rose to about 70° C (158° F), which Arata
explained was due to nuclear and chemical reactions. When he turned
the gas off, the temperature inside the cell remained warmer than the
cell wall for 50 hours, which Arata said was an effect of nuclear
fusion.
While Arata´s demonstration looked promising to his audience, the real
test is still to come: duplication. Many scientists and others are now
recalling the infamous 1989 demonstration by Martin Fleischmann and
Stanley Pons, who claimed to produce controlled nuclear fusion in a
glass jar at room temperature. However, no one - including Fleischmann
and Pons - could duplicate the experiment, leading many people to
consider cold fusion a pseudoscience to this day.
But one witness at the recent demonstration, physicist Akito Takahashi
of Osaka University, thought that the experiment should be able to be
repeated.
"Arata and Zhang demonstrated very successfully the generation of
continuous excess energy [heat] from ZrO2-nano-Pd sample powders under
D2 gas charging and generation of helium-4," Takahashi told New Energy
Times. "The demonstrated live data looked just like data they reported
in their published papers [J. High Temp. Soc. Jpn, Feb. and March
issues, 2008]. This demonstration showed that the method is highly
reproducible."
In addition, researchers will have to repeat the experiment with
larger amounts of the palladium and zirconium oxide mixture in order
to generate larger quantities of energy.
