It is shown in the NEDO project [1,2] that a nano-structured composite metal with hydrogen gas produces anomalous excess heat (AEH) when samples are heated to several hundred degrees. We have developed more convenient heat-generating method [3], using a multilayer composite metal thin film instead of the amorphous metal powder.

The method is superior as follows; easy to make samples, good reproducibility of AEH, easy to observe low-energy radiations. However, the values of the excess heat deduced so far include non-negligible reducible uncertainty, because the evaluation is based only on thermometry, the temperature of the sample core.

In order to reduce the uncertainty as well as to obtain much information on light emission, we are developing radiant calorimetry in which light radiation emitted from the sample is detected over a wide range in wavelength. Employed are a thermometer TMHK-CLE1350 (wavelength 3-5.5 µm) for midIR, an FTIR spectrometer Hamamatsu C15511 (1.5-2.5 µm) for near-IR, and a spectroscope Hamamatsu C10027 (0.3-0.9 µm) for visible light.

Extensive spectral measurements of light radiation provide visual evidence of excess heat power. One can see such an example in Fig. 1, which compares the two spectra measured with (red dots) and without (blue dots) H2 in the NiCu thin film sample heated by the input power of 34.5 W: the red dots exceed the blue dots over the entire region. This difference of radiant intensity is clearly the excess power due to the reaction involving H2.

Detailed analysis reveals the difference of the foil without and with H2 in other physical quantities more specifically: the temperature rises from 942K to 992K, the amount of radiation increases by 6.2%, the emissivity reduces from 0.144 to 0.124. The total excess power is evaluated to be 6.0 W, in this case.

In the present work, we show the result on two types of samples: (1) nanostructured Ni-Cu multilayer film deposited on a Ni plate and (2) pure Ni plate which is used as a substrate of (1). The heat flow analysis was performed based on the temperature measured at three points of the sample holder, the sample surface temperature, and the total radiant heat flow from the sample surface.

It was found that the excess power of 2 – 6 W was observed for the sample (1) and the total energy produced in 120 hours was 0.72 MJ that corresponds to 3.8 keV/H atom. Experimental details and results of measurements will be discussed in detail.

As usual, TGator does not honor requests to leave us the hell alone. His interest is in hijacking these threads and he is not welcome on them.

You have published a lot of LENR experiments. Are they all variations on the Ni/H reaction. That is, do they all come from the same body plan?

Or have you published articles that start with entirely different reactive elements —or body plans —but are called LENR because that’s their results.

***NO. The Ni/H reaction is a variant of the original Pd/D Hydride electrolysis experiments of Pons & Fleischmann.

That is, do they all come from the same body plan?
***They all trace their derivations to the PFAHE, Pons Fleischmann Anomalous Heat Effect.

Or have you published articles that start with entirely different reactive elements
***YES. Most of them are PD/D or PD/H.

—or body plans —
***In the context of all these experiments you might want to define “body plans”.

but are called LENR because that’s their results.
***LENR is the acronym for Low Energy Nuclear Reactions, tracing their name directly to the PFAHE and trying to drop the appellation ‘cold fusion’.
