While Lattice’s presentation at the American Nuclear Society’s 2012 winter meeting concerns production of significant, detectable LENR neutron fluxes during natural lightning discharges, the Widom-Larsen theory that helps us understand this experimentally observed natural phenomenon has potentially far-reaching implications for energy technology and national security writ large; URLs for two brief summaries and further discussion of this possible game-changer are provided.

Commercializing a Safe, Next-Generation Source of ‘Green’ Nuclear Energy
LENR technology is potentially a game-changer for energy markets: involves a breakthrough
paradigm shift in the physics of many-body, collective effects that may in turn enable development of truly
‘green’ nuclear technology for power generation and other applications. This new LENR technology is
potentially revolutionary if successfully commercialized because it does not emit deadly ‘hard’ neutron or
gamma radiation, nor does it produce biologically significant amounts of long-lived radioactive isotopes.

Tips for viewing and listening online: on Saturday, Nov. 17, 2012, we improved the timing
synchronization between the slide transitions and the explanatory audio track. At least with the MS-
Internet Explorer browser, this SlideCast presentation should run by itself from start-to-finish with the
slides being advanced automatically at the correct point in the narrative dialogue about each of the slides.
That said, the auto-advance feature in SlideCast doesn’t always necessarily work perfectly in Internet
Explorer and other web browsers such as Chrome or Firefox. Thus, if you hear an obvious transition
occurring in the audio track (i.e., clicking and rustling noises in background indicating that we’re moving-
on to the next slide; in some cases it is explicitly announced) and the next slide in the sequence fails to
appear within 1-3 seconds, then please manually advance the slide currently being displayed by mouse-
clicking on the 'right arrow' button located just under the slide viewing window of the browser.
Additional online summary information: while Lattice’s presentation at the American Nuclear Society’s
2012 winter meeting concerns production of significant, detectable LENR neutron fluxes during natural
lightning discharges, the Widom-Larsen theory that helps us understand this experimentally observed
natural phenomenon has potentially far-reaching implications for energy technology and national security
writ large; two brief summaries and further discussion of this possible game-changer are as follows:
A public, concise one-page Executive Summary is available online at Lattice’s Internet presence on
SlideShare as follows (it can either be viewed online in ‘fullscreen’ mode on a web browser or
downloaded as a pdf file after a decidedly perfunctory registration):

Potential aerospace propulsion applications: Lattice has recently developed a concept for an LENR
rapid-pulse-detonation propulsion system that could in principle be suitable for 'green' atmospheric
aircraft, energy-density-limited UAVs, and key spacecraft applications that are obvious. Radiologically
speaking, it would be totally 'clean' and could provide tremendous weight/thrust performance advantages
compared to combusting fossil fuels or any conceivable chemical rocket propulsion technologies. Being
‘clean’, it would also be totally unlike the late 1950s Project Orion. For a long-duration/range mission, the
ratio of the required mass of LENR fuel carried on-board divided by total aircraft/spacecraft system mass
would likely be a minuscule number and thus potentially revolutionary if it is successfully engineered.
