. Responsibly imaginable LENR solutions from NASA
--------------------------------------------------------------------------------
Chief Scientist at NASA Langley Research Center Dr. Dennis Bushnell has authored a new report Advanced-to-Revolutionary Space Technology Options The Responsibly Imaginable which includes low-energy nuclear reactions (LENR).
This particular report focuses on how humans might visit Mars. In general revolutionary goals [such as Mars-Humans] require revolutionary technology, writes Bushnell, and LENR is part of NASA Langleys portfolio of solutions.
In this case, responsibly imaginable means that Nominal and usual enabling timescales for such technologies are the order of 12-to-15 years for research and triage, and another 12-15 years for development.
For humans to visit Mars, a large infrastructure must be launched from Earth orbit. This up-mass consists of all the elements to keep humans alive and safe, what NASA describes as pink and warm. Long-term space exploration has so far been powered by radioisotope generators (RTGs), which use radioactive plutonium to make heat that is turned into electricity using thermoelectric converters. Plutonium, aside from being dangerous and dirty, is in short supply these days, and recent Mars robotic rover missions have utilized most of the last store of material.
One thing about LENR, it can make heat. Dr. George Miley, Professor Emeritus at the University of Illinois Urbana-Champagne and head of start-up LENUCO, proposed replacing RTGs with LENR devices at the NETS conference a year ago, and has since speculated how these devices could power domestic needs as well.
Bushnells report also seeks to refute a statement made at a recent USAF workshop that claimed, according to Bushnell, Space is a Mature and Declining field of Endeavour in the U.S.
To do so, he first lists the experimental and commercial efforts with which NASA has been engaged over the decades to develop new useful technologies but that have not succeeded. Then he explains why, writing Essentially, Space Commercialization going forward is hostage to far lower space access/launch costs.

Image credit: NMMSH Archives Tracing current space technology from World War II-era ballistics, Bushnell says that efforts to improve the current chemical fuel technology have been unprofitable within business models because the current cost of access to space is in the range of thousands-of dollars per pound-of-payload.
We have, throughout the Space Age starting in the 1950s, been in thrall to Chemical Propulsion. Breakthroughs in energetics and propulsion beyond Chemical appear to be required going forward.
Fortunately, Bushnell believes that The relatively straight forward applications of the ongoing civilian and military worldwide technology investments will greatly reduce mission cost and enhance safety going forward.
Advances in materials science, information- and nano-technology have reduced the mass of spacecraft and thus the cost, but as Bushnell notes, humans are not shrinking, thus lower-cost lift, propulsion and power systems are required. Thats where LENR comes in, for high-thrust in-space propulsion.
The LENR situation is in a major state of flux with recent apparently successful theoretical efforts and indications of much higher yields, writes Bushnell, adding if proven technologically viable, (LENR) would also be candidates for in space and on planet power.
While the report inventories an array of possible technologies, heres the portion devoted to LENR:
Low Energy Nuclear Reactions, the Realism and the Outlook LENR could, by itself, COMPLETELY Revolutionize Space access and utilization. Although there is a quite long history of anomalous observations including transmutations the recent consideration of Low Energy Nuclear Reactions begins with the Pons/ Fleishman late 80s observations and assertions regarding what they termed Cold Fusion. Subsequent difficulties with experimental replication and an utter lack of convincing theoretical explication forced research in this arena underground with minimal financial support.
The current situation is that we now have over two decades of hundreds of experiments indicating heat and transmutations with minimal radiation and low energy input. By any rational measure this evidence indicates something real is occurring.
So, is LENR Real? Evidently, from the now long standing and diverse experimental evidence yes With effects occurring using diverse materials, methods of energy addition etc. This is FAR from a Narrow Band/episodic set of physical phenomena.
The next consideration is WHAT IS REAL? WHAT IS Happening? For NASA Langley the epiphany moment on LENR was the publication of the Widom-Larsen weak interaction LENR Theory. This theory is currently under study and experimental verification [or not] at NASA LaRC. The theory appears to explain nearly all the various and often variegated experimental observations and shifted the LENR Theoretical focus from some way of fooling Particle Nuclear Physics/The Strong Force to Condensed Matter Nuclear Physics, Collective Effects, The Weak Force and Heavy Electrons. The Strong Force Particle Physicists have of course evidently been correct all along, Cold Fusion is not possible. HOWEVER, via collective effects/condensed matter quantum nuclear physics LENR is allowable without any Miracles. The theory states that once load surfaces with hydrogen/protons and add some energy IF the surface morphology enables high localized voltage gradients then heavy electrons leading to ultra low energy neutrons will form, neutrons that never leave the surface. The neutrons set up isotope cascades that results in beta decay and heat and transmutations with the heavy electrons converting the gamma from the beta decay into heat.
The theory indicates several key issues/circumstances are required to enable-to-optimize LENR and explains the various experimental observations, including the often long initiation times required in some experiments. If the theory is experimentally validated in detail it provides the understanding to shift LENR research from discovery into engineering development. The theory indicates energy densities some million times chemical, the current experiments are in the 10s to hundreds range. However, several labs have blown up studying LENR and windows have melted, indicating when the conditions are right prodigious amounts of energy can be released/produced. There are some 6 or so groups claiming device outputs in the 100 watt range and 3 others claiming kilowatts. Efforts are ongoing within NASA and other organizations to validate, or not, these claims. It should be noted that these devices are essentially Edisonian, the result of attempts at experimental discovery vice ab-initio design from the weak interaction theories per se.
The LENR situation and outlook is therefore the following: Something real is happening, the weak interaction theories suggest what the physics might be, there are efforts ongoing to explore the validity of the theories, there are continuing Edisonian efforts to produce devices, mainly for heat or in some cases Transmutations. There are efforts to certify such devices. We are still FAR from the theoretical limits of the weak interaction physics and are in fact inventing in real time the requisite Engineering, along with verifying the physics. When we concentrated upon Nuclear Engineering beginning in the 1940s we went, jumped to the strong force/particle physics and leapt over the weak force, condensed matter nuclear physics. We are going back now to study and hopefully develop this arena.
The Precautionary Principle demands that we core down and determine realism for this arena, given the truly massive-to-mind boggling benefits Solutions to climate, energy and the limitations that restrict the NASA Mission areas, all of them. The KEY to Space Exploration is Energetics. Some examples of what LENR might/ could enable in a resultant Energy Rich Exploration context include:
- Refrigeration for Zero Boiloff cryo storage - Active Radiation protection - High Thrust Vasimir/MHD Propulsion - Energy Beaming - Separation of propulsive mass and energy/ energetics to establish the requisite conductivity for most harvested propulsive mass including regolith - Planetary Terraforming - Ubiquitous in space and on-planet sensors and robotics - LEO propulsion - On planet power and energy - EDL retro via heating of ingested mass
Also, The Key to SSTs and neighbor-friendly personal fly/drive air vehicles is Energetics, as simplex examples of the potential implications of this area of research. There are estimates using just the performance of some of the devices under study that one percent of the nickel mined on the planet each year could produce the worlds energy requirements at the order of 25 percent the cost of coal. No promises but something[s] seriously strange are going on, which we may be closer to understanding and if we can optimize/engineer such the world changes. Worldwide, worth far more resources than are currently being devoted to this research arena. Need to core down and determine Truth. If useful, need to engineer/apply.
Dr. Dennis Bushnell Advanced-to-Revolutionary Space Technology Options The Responsibly Imaginable
They wont call it cold fusion, but NASA is keeping an open-mind to new energy technology through experimentation and testing a LENR theory. Bushnell knows the importance of not picking the winner too early on. It isnt easy, even for a national Chief Scientist.
In the report, Bushnell quotes Ivan Bekey from his Chapter 9 Long Term Outlook for Commercial Space in the book Toward a Theory of Space Power:
The Nations space programs are in a horrible mess and appear to be locked in a downward spiral. Almost all defense and civil government space programs suffer from similar symptoms:
no toleration of or planning for failures avoidance of risk lack of funding for new technologies inability of industry to afford research or to develop technologies alone suppression of disruptive technologies disappearance of the concept of experimental systems in space. As a result of these symptoms, the following conditions are now the norm: absence of innovation long timelines for even modestly new developments billion-dollar price tags for major systems major overruns and schedule slips need for long on-orbit life to amortize the investment obsolescence of systems upon launch or soon thereafter.
Bushnell sums it up with:
Overall As mentioned in the Bekey comments cited herein, the pursuit of Revolutionary Space Technologies has over the years been akin to a battle, with the forces of conservatism/evolution consistently winning over those advocating risky/huge payoff REAL Game-Changing approaches. The Space Community has simply been unwilling to make the investment of time and treasure to ideate and triage/develop Revolutionary Technologies, resulting in Space being largely and still a high capital investment evolutionary at best Industrial Age Endeavour in the IT age heading rapidly to the Virtual Age.
and ends with this quote of Ivan Bekey:
The battle is within. It is a cultural one: between glorifying the past or marching toward the future, between protecting successes or cannibalizing them, between averting risk or embracing it. The battle is for the soul of the of the Industry [and the Future of Humankind in Space]
and well add on Earth too!
The short version: “We want more money!” Right. Saving the world ain’t cheap.
I’m going to mark Dennis Bushnell down as: “Believer”
True. But surely we can afford to invest a tiny fraction of what has already been spent on "hot fusion" with pretty nil results.
And better to spend it here than on most of the "global warming" prevention schemes thus far put forward.
That disturbs me a bit. From my point of view, there should be big money in “saving the world.”
Al Gore would agree, I think. Meanwhile we’re still waiting on him to deliver.
“True. But surely we can afford to invest a tiny fraction of what has already been spent on “hot fusion” with pretty nil results.”
How about reducing the amount spent on “hot” fusion to the same level as “cold” fusion? Or eliminate both.
I can only think of a few hundred projects that would bring quick benefits to a lot people if it had an infusion of a couple of billion dollars.
No, because we need the energy if we are going to raise the standard of living of all humanity to that of the USA/EU today.
"I can only think of a few hundred projects that would bring quick benefits to a lot people if it had an infusion of a couple of billion dollars."
Try thinking up ONE project with the potential impact of practical cold fusion technology. I doubt that you can.
Neither the U.S. nor E.U. is able to maintain the standard of living it has let alone raise the living standards of the rest of the world and it has little to do with virtually free energy, a mental perpetual motion machine.
“Try thinking up ONE project with the potential impact of practical cold fusion technology. I doubt that you can.”
(1) a technique for very efficient water desalinization
(2) food crops that would grow well on very marginal land
(3) an inexpensive any stage cure for malaria
That's with one hand tied behind my back.
With abundant energy, raising the standards would be not just possible, but easy.
"(1) a technique for very efficient water desalinization
Abundant energy fixes this, if by nothing more than direct distillation.
"(2) food crops that would grow well on very marginal land".
Abundant energy fixes this (vertical agriculture).
"(3) an inexpensive any stage cure for malaria"
Affects only a small portion of the world's population. Small impact on the totality of humanity.
All in all, a weak effort on your part.
“With abundant energy, raising the standards would be not just possible, but easy.”
Anyone can recognize what an absurd statement that is. Abundant energy must also be inexpensive energy to raise standards of living.
Diverting limited funds into paying for our expensive energy use reduces investment into other areas.
Malaria
“Affects only a small portion of the world’s population. Small impact on the totality of humanity.”
Oh really? And who told you this nonsense?
Malaria
Affects only a small portion of the worlds population. Small impact on the totality of humanity.
Oh really? And who told you this nonsense?
***Wikipedia
The World Health Organization has estimated that in 2010, there were 219 million documented cases of malaria. That year, between 660,000 and 1.2 million people died from the disease,[1] many of whom were children in Africa.
You should have read further:
“Malaria is not just a disease commonly associated with poverty: some evidence suggests that it is also a cause of poverty and a major hindrance to economic development.[118][119] Although tropical regions are most affected, malaria’s furthest influence reaches into some temperate zones that have extreme seasonal changes. The disease has been associated with major negative economic effects on regions where it is widespread. During the late 19th and early 20th centuries, it was a major factor in the slow economic development of the American southern states.[120]
A comparison of average per capita GDP in 1995, adjusted for parity of purchasing power, between countries with malaria and countries without malaria gives a fivefold difference ($1,526 USD versus $8,268 USD). In countries where malaria is common, average per capita GDP has risen (between 1965 and 1990) only 0.4% per year, compared to 2.4% per year in other countries.[121]”
One need not be ill or die to be negatively affected. Send a few mystical, magical e-cats and all will be well, right?
What a weak defense. Typical of anti-LENR skeptopaths.
Those e-cats are going to have to be imagined since they don’t exist and won’t in the foreseeable future.
LENR solutions from NASA”? Exactly what “lenr solutions” has NASA came up with?
It's only absurd if you don't realize that small, modular mass-produced, essentially fuel-less generators (and hence the energy from them) WILL become inexpensive, and quickly. The same factors that let high-technology and mass production make cell phones ubiquitous throughout the third world will work exactly the same way.
"Diverting limited funds into paying for our expensive energy use reduces investment into other areas.
See paragraph above. The potential impact of LENR technology is simply too great NOT to invest in the research. The shenanigans of the "hot fusion physicists" who have managed to stall LENR for all these years essentially constitutes a crime against humanity.
[Malaria} Affects only a small portion of the worlds population. Small impact on the totality of humanity.
"Oh really? And who told you this nonsense?
LOL. I can read a population map and a map of the extents of malaria infestations. Try it yourself, you might learn something. But I don't expect honest debate from skeptopaths. And widespread, abundant, and inexpensive energy will help even here (see "bug zapper").
HMMMMM....potential product....solar powered bug zapper?? Charge up outside during the day, bring indoors at night??
responsibly imaginable....
what ever happened to grammar police?
They went to work for Obama, and are happily investigating "tea party" groups.
lol
