A report from the U.S. Defense Threat Reduction Agency (DTRA) claimed government researchers had confirmed the existence of a cold fusion nuclear reaction. The report was allegedly authored by scientists from Space and Naval Warfare Systems Command and the University of New Mexico.
“My instinct is to ascribe these results to cosmic ray deuterons interacting with the palladium deuteride. I would be want this potential background to be addressed before I could interpret this as a finding of new physics.” Dr. Jeffrey Eldred, a particle accelerator physicist who works at Fermilab, told The DCNF. “Isotope effects on superconductivity have been demonstrated prior to these results.”

Link's busted, but is this the palladium/deuterium reaction controversy that's been running for years? There's a constant low-level interest in that from the DoD, I find it very interesting that nobody's been able to conclusively prove or disprove this supposed effect yet, even 20+ years after the original paper by Fleischmann and Pons. Realistically I sort of doubt that it'll be an energy revolution, we're much further ahead on traditional high-temperature fusion for that, but it's definitely worth keeping an eye on.
EDIT: LENR and the Fleischmann/Pons "cold fusion'" experiment are the same thing, just a more accurate name. Fusion would have a distinctive radiation signature that's not been observed with LENR (I think), but the popular media and layman's term is cold fusion.
Significant results of the sequential etching are summarized in Figure 3.1-9. Sequential
etching of detector 10-7 showed proton recoil tracks. Figure 3.1-9a shows the proton recoil
spectrum obtained for detector 10-7. It is compared to the proton recoil spectrum obtained for
252Cf neutrons. This comparison shows that detector 10-7 has been exposed to 2.3-2.45 MeV
neutrons. The neutron emission rate was estimated to be 1-3 n/s. Blank detectors did not show
proton recoils inside the detector indicating that the source of the neutrons observed in detector
10-7 was the Pd/D deposit on the Ag cathode. Figure 3.1-9b shows the spectrum obtained for the
front side of detector 10-5 after 21 h of etching. The tracks are identified to be due to 3 MeV
protons and alphas of energies of 12 and 16 MeV.
3.1.5 Summary of LET spectrum analysis of CR-39 detectors used in the SRI replication
Dazhong Zhou, of NASA-Johnson Space Center, took the scanned data of detectors 10-5 and
10-6 that Forsley had done and analyzed them using a LET spectrum method.28-33 Applying the
LET spectrum method to the scanned data, the LET spectrum ( differential and integral fluence),
Figure 3.1-10, and energy distributions of the charged particles, Figure 3.1-11, were determined.
For protons, a the major peak is observed at ~ 11.5 – 12 MeV for the front CR-39 surfaces and
These results suggest that multiple channels are possible, i.e., one channel results in heat and 4He,
another results in neutrons, and yet another tritium. The implication is that by controlling
experimental parameters, it should be possible to switch back and forth over the various
channels, a concept that Swartz35 refers to as the ‘optimal operating points (OOPs).
Once understood, LENR has the potential to be a paradigm-shifting, ‘game-changing’
technology. Nuclear energy systems have power densities six orders of magnitude greater than
chemically-based energy generation or storage systems. The ability to harness a new nuclear
energy source for either thermal or electrical conversion, without the generation of penetrating
energetic particles, would have a profound commercial and military impact ranging from small
footprint power systems to mobile systems to larger stationary power systems. Depending on
how the technology scales, it could be used as a power source for expeditionary warfare and
military bases as well as surface ships/submarines; nuclear battery for autonomous C4I
operations (communications, computers, satellites); and long duration UAV and USV ops
(propulsion). Such a technology would have a profound effect upon one of the U.S. and DoD’s
largest financial and environmental costs: burning hydrocarbons from imported oil and gas with
their attendant CO2 footprint. Indeed, many U.S. military actions this century, and the most
costly in the 1990’s, have been driven by, or consequences of, the geopolitics of oil. Decreasing
the use of foreign oil would result in both an energy savings and a reduction in US military
presence, and fleet costs, in maintaining access to foreign oil and natural reserves.
