Defense Threat Reduction Agency
June 6, 2017 – By Steven B. Krivit –

Theorist Lewis Larsen, co-developer of the Widom-Larsen theory of low-energy nuclear reactions (LENRs), recently discovered a favorable Department of Defense evaluation of his and Allan Widom’s LENR theory.

Larsen told New Energy Times that he found the document, an official U.S. Defense Threat Reduction Agency report, on the Homeland Security Digital Library Web site while carrying out a random Internet search in May.

The report was produced in March 2010, when two physicists, Edward Toton and George Ullrich, under contract with the Advanced Systems and Concepts Office, a think tank that is part of the U.S. Defense Threat Reduction Agency, favorably analyzed Larsen and Widom’s theory.

Toton is a consultant with a long history in defense-related research, and Ullrich was, at the time, a senior vice president for Advanced Technology and Programs with Science Applications International Corp.

Toton and Ullrich summarized their evaluation with a question: “Could the Widom-Larsen theory be the breakthrough needed to position LENR as a major source of carbon-free, environmentally clean source of source of low-cost nuclear energy??”

Larsen spoke with the two physicists from 2007 to 2010 to help them understand key details of his and Widom’s theory of LENRs.

The authors summarized their evaluation in a slide presentation on March 31, 2010, in Fort Belvoir, Virginia. Their slides were geared toward a technical audience and included, with acknowledgments, some information and graphics taken directly from Larsen’s slides, originally published on SlideShare.

The Toton-Ullrich summary does an excellent job of distilling Larsen’s explanation of why LENR experiments produce few long-lived radioactive isotopes:

  • In surface patches that experience large fluxes of ULM neutrons, populations of neutron-rich “halo” nuclei will build up.
  • The half-lives of these nuclei are longer than they would be if isolated because they are unable to emit beta-electrons or shed neutrons into unoccupied states in the local continuum.
  • The cessation of ULM neutron production will trigger serial cascades of fast beta-decays from neutron-rich into stable isotopes.
  • Few long-lived radioisotopes remain after this process has run its course.

Kirk Shanahan is a physical chemist employed by the U.S. Department of Energy’s Savannah River National Laboratory. As this Freedom of Information Act request response shows, he spends a large amount of time attempting to discredit low-energy nuclear reaction research claims.

I published the graph above in my recent White Paper “Power Generation Via LENRs.” I received a response regarding the graph from Einar Tennfors, a retired Swedish plasma physicist. He claimed that the anomaly shown in the graph, an increase in LENR cell temperature concurrent with a decrease in input power, was easily explained by conventional science.

Tennfors said the temperature rise was due to increased conductivity in the cell. I asked him what causes the cell conductivity to increase. He said ion mobility increases with temperature. I asked him what causes the temperature rise that causes the ion mobility to increase. He said the heating is due to the interaction between the ion current and the surrounding ions.

I decided to seek a critic who could attempt a better argument. Shanahan was the man.

Japan Funding LENR Research
March 13, 2017 – By Steven B. Krivit –

A Japanese government Web site confirms that two of Japan’s largest automobile manufacturers are participating in the government’s multi-year low-energy nuclear reaction (LENR) research program, first reported by New Energy Times in 2015.

The New Energy and Industrial Technology Development Organization (NEDO), a Japanese government research and development agency, operates the Web site. LENR advocate Jed Rothwell, who speaks Japanese, found the Web page with the update today. (PDF Archive)

Japan is the first nation in two decades to make a substantial commitment to this research, which offers vast, unexplored opportunities in energy and materials science.

The participants in the government-sponsored program include Technova, a member of the Toyota Motor Corp. family of businesses, Nissan Motor Co., and four universities, Tohoku, Kyushu, Nagoya and Kobe.

Meanwhile, progress in LENR research in the U.S. has been delayed, the result of a lingering stigma created by science authorities tasked by the U.S. Department of Energy who, in March and April 1989, bet against confirmation of a new nuclear process, as explained in the 2016 book Hacking the Atom.

When confirmatory experimental results were reported in the summer of 1989, some people in the government science establishment went to great lengths to ignore and dismiss the data. The 2016 book Fusion Fiasco explains precisely and for the first time how this scientific cover-up happened and who was responsible.

Power Generation Through LENRs: Prospects, Problems and Paths Forward
A White Paper by Steven B. Krivit

Feb. 23, 2017

Introduction

For the past 100 years, most scientists thought that nuclear reactions could occur only in high-energy physics experiments and in massive nuclear reactors. But experimental research, and the Widom-Larsen theory, suggest that there is more to know: Nuclear reactions can also occur in small, benchtop experiments. Low-energy nuclear reaction (LENR) research has the potential to open the door to a new kind of nuclear power generation without harmful radiation emission, greenhouse gas production, or the possibility of runaway chain reactions.

The Widom-Larsen theory, which does not require any new physics, provides a sensible, mathematically rigorous explanation for most of the previously incomprehensible experimental observations. A complete list of the Widom-Larsen papers, including critique and response to critique, are available on this Web page. A brief summary of the seven papers is available on request.

LENRs are neither fusion nor fission but instead provide a third potential pathway to nuclear energy. LENRs may also provide a means of transmuting elements, including rendering dangerous radioactive isotopes inert. LENR fuels may consist of ordinary hydrogen, along with metallic nanoparticles composed of nickel, titanium, palladium, other transition metals, or tungsten. At first glance, a clean, radiation-free nuclear energy technology sounds too good to be true; this concern has been one of the impediments to broader acceptance of LENRs. This paper outlines key evidence that establishes the scientific validity of LENRs, identifies issues interfering with its acceptance, and discusses future opportunities in LENR research.
