Purpose
The purpose of this research is to investigate the potential vehicle performance
impact of applying the emergent Low Energy Nuclear Reaction (LENR)
technology to aircraft propulsion systems. LENR potentially has over 4,000 times
the density of chemical energy with zero greenhouse gas or hydrocarbon
emissions. This technology could enable the use of an abundance of inexpensive
energy to remove active design constraints, leading to new aircraft designs with
very low fuel consumption, low noise, and no emissions. The objectives of this
project are to: (1) gather as many perspectives as possible on how and where to
use LENR for aircraft including the benefits arising from its application, (2)
explore the performance, safety, and operational impacts to individual aircraft
and the fleet, (3) evaluate potential propulsion system concepts, and (4) foster
multi- disciplinary interaction within NASA.
Background
LENR is a type of nuclear energy and is expected to be clean, safe, portable,
scalable, and abundant. The expected benefits make it an ideal energy solution.
When it is applied to aircraft, LENR removes the environmental impacts of fuel
burn and emission from combustion. Excess energy can be used to reduce noise
so that all three of NASA’s technology goals for future subsonic vehicles are
either eliminated or addressed. Furthermore, aviation impacts almost every part
of our daily lives, civilian and military. A revolutionary technology like LENR has
the potential to completely change how businesses, military, and the country
operate as a whole, giving a tremendous financial, tactical, and resource
advantage to the country that utilizes it in the most effective way.
LENR creates some unique capabilities as well as challenges for integration into
aircraft. The LENR concept that has reported most of the success generates heat
in a catalyst process that combines nickel metal (Ni) with hydrogen gas (H). The
initial testing and theory show that radiation and radioisotopes are extremely
short lived and can be easily shielded. Although nuclear fission has been looked
at for use in aircraft, LENR is different. LENR has a higher energy density and no
radioactive by products.
Success of this research will provide a firm foundation for future research and
investment for LENR technology integration into aircraft. Key research and
development areas will be identified with any gaps in the current technology
research. This research will guide NASA on the most effective way to invest in
LENR to be the world leader in LENR aircraft research.

Tra le due alternative voto BUFALA, ma forse una definizione appropriata è "wishful thinking".

Da quello che è scritto negli articoli originali mi sembra chiaro che si parli semplicemente di una "ricerca per investigare le potenzialità di ..."
Inoltre mi sembra che nel programma del seminario ci siano cose molto interessanti per possibili miglioramenti in campo aeronautico

Twenty NASA civil servants received awards of $150,000 for research efforts lasting 12 months. Efforts that show significant progress after a year could be selected to receive a larger grant for 12 more months of research.
Period of performance: February 1, 2013 to January 31, 2014

Insomma, Rossi e' riuscito a vendere il suo e-cat.
Diceva che non voleva metterlo a disposizione dei test italiani per non svelarne il funzionamento perche' non voleva rimanere povero e a quanto pare e' riuscito a farci dei soldi

Hidden away in the secret depths of the Skunk Works, a Lockheed Martin research team has been working quietly on a nuclear energy concept they believe has the potential to meet, if not eventually decrease, the world’s insatiable demand for power.

Dubbed the compact fusion reactor (CFR), the device is conceptually safer, cleaner and more powerful than much larger, current nuclear systems that rely on fission, the process of splitting atoms to release energy. Crucially, by being “compact,” Lockheed believes its scalable concept will also be small and practical enough for applications ranging from interplanetary spacecraft and commercial ships to city power stations. It may even revive the concept of large, nuclear-powered aircraft that virtually never require refueling—ideas of which were largely abandoned more than 50 years ago because of the dangers and complexities involved with nuclear fission reactors.

Yet the idea of nuclear fusion, in which atoms combine into more stable forms and release excess energy in the process, is not new. Ever since the 1920s, when it was postulated that fusion powers the stars, scientists have struggled to develop a truly practical means of harnessing this form of energy. Other research institutions, laboratories and companies around the world are also pursuing ideas for fusion power, but none have gone beyond the experimental stage. With just such a “Holy Grail” breakthrough seemingly within its grasp, and to help achieve a potentially paradigm-shifting development in global energy, Lockheed has made public its project with the aim of attracting partners, resources and additional researchers. .....
