In Livermore, Still Waiting on Nuclear Fusion

The National Ignition Facility in Livermore, California, has been called a modern-day moon-shot, a project of "revolutionary science," and "the mother of all boondoggles."

NIF, as it's known, is a five-billion dollar, taxpayer-funded super laser project whose goal is to create nuclear fusion – a tiny star – inside a laboratory. But so far, that hasn't happened.

The facility, which began operating in 2009 after a decade of construction at a cost of almost $4 billion, points 192 football-field-sized lasers at one tiny capsule the size of a peppercorn and filled with hydrogen. It creates degrees of heat and pressure never before achieved in a lab.

Standing outside NIF’s target chamber in 2008, about a year before NIF’s dedication, Director Ed Moses called NIF “more far-out, and far cooler than anything in science fiction or fantasy.”

A tiny star for a blip in time

“For a brief period of time, not a hundredth or a thousandth, but a billionth of a second,” explained Moses, “we will raise the temperature of the target to a hundred million degrees.

“That’s higher temperature and more pressure than exists at the center of our sun. It’s a hundred million times more pressure than you’ll find at the deepest part of the ocean.”

Under those conditions, the hydrogen atoms could enter into a state of controlled nuclear fusion. (In nuclear fission, as in nuclear power plants, energy is generated by splitting atoms. Fusion is the opposite: Atoms are smashed together.)

The goal is referred to as “ignition.” It would put out more energy than the lasers had put in to it.

If scientists can make ignition happen at NIF, that achievement could, theoretically, be parlayed into a new kind of nuclear power plant. Unlike fission plants, which eat up uranium and generate radioactive waste, these fusion plants would run on water, and create virtually no waste at all.

Waiting to ignite

At NIF's dedication in 2009, George Miller, then-head of the Lawrence Livermore National Laboratory, seemed to believe that ignition was right around the corner.

“I think we will get ignition,” Miller told the crowd. “I think we'll get ignition relatively shortly after we turn the facility on.”

Since then, the strength and functionality of the lasers have received praise from the physics community.

“The laser has been working phenomenally,” said Christopher Deeney, who directs the Division of Defense Science at the National Nuclear Security Administration, which oversees NIF. “It's the most controllable, precise laser the community has ever built.”

But ignition – the goal at the center of NIF’s name — hasn’t happened. “We just haven't gotten it to burn yet,” explained Moses at a recent interview.

In a July 19, 2012 report, the NNSA concluded that “the probability of ignition before the end of December is extremely low.” The report called the functionality of the lasers “outstanding,” but blamed NIF’s computer simulations for the failure to ignite.

An NNSA ignition deadline of October 1, 2012, has now come and gone.

Moses bridles at the idea that anyone can put a deadline on this achievement.

“We never guaranteed anything on any particular date,” he says. “People have to sort of get used to that. That’s what great science is.”

Nevertheless, by law, on November 30th, Department of Energy Secretary Steven Chu is required to report to Congress on why NIF hasn't met its goal, despite significant cost to taxpayers: about 300 million dollars a year on top of over three billion in construction costs.

For Christopher Paine, a longtime NIF critic with the Natural Resources Defense council, this amounts to an “I told you so” moment.

“This project has gone on a long time,” he says, “billions of dollars invested. But to what end?"

What is NIF for?

Paine's criticism of NIF boils down to two objections: the project's expense and what you might call a muddled sense of purpose. What, in other words, is NIF for?

There are three answers to that question, explains a 2009 NIF promotional video.

“NIF will explore controlled nuclear fusion to ensure global security, enable sustainable clean energy, and advance our understanding of the universe.”

Let’s break that down.

Reason number one: Global security. This is the primary intent of NIF, and it has to do with the fact that actual nuclear bomb tests have been banned worldwide.

Because NIF simulates a nuclear reaction in a tiny pellet, you could test the strength of nuclear bombs without having to actually explode them.

Paine believes that’s unnecessary. "We haven’t had NIF for the last 20 years," he says, "and we've been maintaining the stockpile."

NNSA"s Deeney disagrees, calling NIF a “key element in our stockpile stewardship program.” He says important experiments can be done at NIF even without ignition. “We're committed to NIF for the long term,” he says.

Reason number two: Clean, fusion energy. This is a very long-term goal. Even if NIF does achieve ignition, it could take decades to adapt that technology into a working fusion power plant, something that could power a light bulb in your house.

A 100-year solution to a 20-year emergency

Paine says with climate change, we don't have that kind of time.

“Dealing with climate change is a 20-30 year planetary emergency,” says Paine. “Fusion energy is irrelevant to that timescale. Humanity needs to change its ways now. It needed to change its ways yesterday. Fusion energy is a 50 to 100-year project with no assurance of success.”

At NIF, the goal is to create nuclear fusion — a tiny star — inside this peppercorn sized "hohlraum." Credit: NIF

But it's the third reason, to “advance our understanding of the universe,” that Moses emphasizes these days.

“The Higgs Boson was just discovered at the [Large Hadron Collider] in CERN, at a cost of ten billion dollars,” he points out. “Was it late? Was it early? Was it on time?”

The answer, he says: Who cares? Moses calls these types of projects “grand challenge science,” and insists they cannot be performed on deadline.

“It’s not grand challenge science if you know the answer before you start,” says Moses. “And this is exactly that.”

NNSA's Christopher Deeney also declines to predict when NIF will achieve its goal.

“Right now we will not make a prediction of when ignition will happen,” he says. “It's still a discovery science project. Right now it's unpredictable.”

That's the case NIF's advocates will have to make to Congress at the end of this year. It’s worked so far. After all, NIF has something for both sides of the aisle: Democrats like clean energy, Republicans like weapons security.

But everyone likes a breakthrough, and at NIF, that's still out of reach.

    This is money well spent, unlike most of the federal "budget". I have to put the word in quotes because they haven't even had a budget for the last three years. How pathetic is it to criticize something like this when we are hemmoraging a trillion dollars year for no reason whatsoever?

    The idea that we shouldn't bother because we'll all be dead from "climate change" in 30 years is even more ridicuolous.

    From what I read it sounds like the lasers are working well, but there is a computer simulation problem. That sounds to me like something that can be fixed.

  • sjo

    This is the greatest task the human race right now.

  • Jaq

    +1 on money well spent. It'd be cheap at twice the price. Developing fusion energy is the single-most important energy-related, scientific goal at present. Tidal energy, wind, geo-thermal, solar; all of these have potential, but none are as attractive and potentially powerful as fusion. All of them also require huge infrastructure commitments in the forms of complex tidal barriers, vast swathes of land covered with solar/wind generators, or massive mining/drilling projects and exchange plants to pull heat energy (usually in the form of caustic/corrosive gases and liquids) from below the earth's surface. Fusion tech is no small thing; fusion plants would be sizeable and expensive. But they'd be relatively self-contained and generate far more – and cleaner – power per footprint than any of the others. And they can be placed anywhere; no need for sunny climes, geologically active areas, or beautiful coastlines & tidal flats. They can take up the ugliest, most barren real estate on earth, and bring skilled jobs – and resulting wealth – to those areas at the same time.

    And that goes for off-world applications as well. If we're ever going to establish mankind permanently on the moon, or Mars, what better way than to do so by powering those outposts with Helium 3, the gold standard of fusionable material that is incredibly rare on Earth, but hugely abundant on the moon?

    As with putting a man on the moon, the pursuit of sustainable fusion – literally a quest for fire – should, in the words of JFK, "serve to organize and measure the best of our
    energies and skills, because that challenge is one that we are willing
    to accept, one we are unwilling to postpone, and one which we intend to
    win, and the others, too."

  • Robert Steinhaus

    It is not wise
    to discount the ultimate potential of fusion

    (which is indeed very great).

    Current leadership at LLNL is excessively aggressive in pushing the promise of

    NIF and LIFE while being insufficiently careful to state precisely, in worlds

    that convey accurate meaning, the current status and level of achievement of

    NIF researchers in producing a practical form of fusion that ultimately

    produces more energy as output then it takes to run the NIF experiment and

    power its lasers from the power lines. NIF program has repeatedly made claims
    to the press dramatically announcing we are approaching "break-even" and "energy gain". The facts are that NIF is in fact still 2 orders of magnitude away from generating the amount of fusion energy that would equal the energy that must be drawn from the power grid to run the Laser fusion experiment.

    A question I would invite Amy Standen (author of this article) to ask NIF managers
    prior to writing a future article on NIF –

    Is it not true that NIF in its current form, even under the most favorable
    circumstances, will never produce as much energy from fusion as the electrical energy this
    experiment must draw from the power grid to operate the experiment?

    The NIF Laser is only about 1% efficient (or less) at converting electrical
    line power into frequency tripled laser light power used to heat the fusion
    plasma. The yield from fusion per shot would have to be 100 times higher than it is currently to
    produce energy break-even the way lay persons in the public would understand
    break-even from their common experience. It would be the reasonable expectation
    of the public that if the scientists at NIF said their experiment achieved
    break-even, then you would actually get more energy from fusion than it takes in
    electricity drawn from the power lines to run the experiment and power its
    lasers. NIF fusion scientists currently define "break-even" in a way that is 100 times easier to achieve than what the public understands when they hear the words "break-even", so there is (deliberate?) miscommunication in every press release produced by LLNL descibing ignition, "break-even", and the current status of the NIF experiment.

    An Inconvenient Truth to be verified by careful questioning of NIF fusion
    scientists –

    Even if “ignition” is achieved (More Power out of NIF than the power

    delivered to the fusion plasma by laser light), NIF still produces only a tiny
    small amount of energy each NIF shot. If, at some point, NIF achieves the long
    sought goal of ignition and break-even, it will still only produce a tiny 1.8 Mega-joules of energy in a period of about 23-nanoseconds each shot.

    While most laypersons and reporters may not be that familiar with the energy

    unit (Mega-joules) this 1.8 Mega-joules of energy is as much

    energy as would be produced by efficiently burning 0.014 gallons of diesel

    The most rapid cycle time that currently can be achieved at NIF is about 8

    hours between shots, so with a maximum effort and three shifts a day of work,

    NIF could produce three shots a day with a combined energy output of 54 Mjoules. This
    amount of energy is equivalent to efficient burning 0.042 gallons of diesel
    fuel a day.

    Without significant scaling and redesign, NIF in its current configuration cannot
    provide the energy that America needs, at commercial Gigawatt levels, to
    achieve real American energy security.



    • James

      I pray you get the help you need. Science is a gift from God if you believe in God. Fusion is how God powers the galaxies. Why wouldn't we try to learn about this wonderful process. Further how can you speak such mean things about people working on this project. You so called Christians need to actually do what he said.

  • Robert Steinhaus

    A suggestion on how to get NIF to work – (if ignition does not occur at NIF in ultra-violet laser light, switch to green)

    The Lawrence Livermore National Lab NIF experiment has recently failed to
    achieve ignition at the end of a 3 year National Ignition Campaign [1].

    It is important for the future of fusion in the United States for NIF to
    ultimately work. A dramatic failure at NIF would be very damaging to both the
    Lawrence Livermore National Laboratory and to the hopes and prospects for
    fusion in America in our lifetimes.

    A valuable feature of NIF is the final optical system that converts the
    fundamental 1,053-nanometer (1-omega, or 1ω) infrared light to higher harmonic
    frequencies and focuses it onto the target. This NIF optical system is designed
    to be flexible to support a variety of missions.

    Suggestion: In 2008, LLNL investigated a 2ω configuration of the NIF laser

    If the 1.8 MJ 3ω X-ray configuration of the NIF laser is currently not able to
    produce ignition of tiny 1.8 MJ hohlraums, why not try a 2ω configuration where
    the laser is capable of delivering more power in the green spectrum (526.5 nm)
    and potentially capable of igniting a significantly larger hohlraum producing
    100 – 200 MJ per shot?

    In 2008 NIF researchers reported in Applied Optics [2] on the performance of
    a single NIF beamline operated at its second-harmonic wavelength of 526.5 nm
    (2ω). In 2008 record single-beamline pulsed energies were produced up to 17.7
    kilojoules (kJ) (equivalent to 3.4 megajoules (MJ) for the full 192-beam NIF).
    Shaped pulses with focal spot smoothing were produced at energies that are
    consistent with high-energy-density experimental designs, including high-gain,
    high-yield 2ω ignition.

    The potential for operation at very high 2ω energies, in excess of 3MJ,
    might justify reevaluation and review. The increased fluence limits for optical
    damage at 2ω make it possible to consider routine 2ω operation of the laser at
    these energies while maintaining or reducing operating costs.

    In the conventional NIF laser 3ω configuration. 1.8 Mega-joules of energy is
    expected to be produced from the NIF hohlraum, this is a tiny amount of energy
    equivalent to the energy produced by efficiently burning 0.014 gallons of
    diesel fuel.

    Using the 2ω green light configuration of NIF allows significantly more
    power to be safely generated by the laser, to the point that ignition of 200 MJ
    hohlraums should be possible. 200 MJ of fusion energy is equivalent to 1.45
    gallons of diesel fuel. This is over 100 times the energy produced by the small
    1.8 MJ 3ω hohlraum.

    The cited Applied Optics report [1], indicates
    that 2ω operations of shots of up to 3.4 MJ full NIF equivalent can be produced
    that result in no optical damage. 2ω operation of the NIF Laser would permit
    higher operating power than the 3ω conventional configuration and permit
    larger, lower-temperature, but higher yield hohlraums to be used. Because of
    the higher energies available (of up to 3.4 MJ) at 2ω, these larger targets are
    reported to have calculated fusion yields as high as 100 to 200 MJ and this
    would be a much nicer and more practical yield to use to scale from for actual
    fusion power plants of the future.

    If we spent less time blowing each other up and more time figuring out things like this we'd fulfill our potential as a species.

  • fusioneer

    Dear Mr. Steinhaus,

    Unfortunately, the foundational ideas about how nuclear fusion actually works or occurs has been wrong for more than 60 years. What is interesting is that the model of how fusion works is promoted in every textbook on physics all over the world and hardly anyone has ever questioned the foundational concepts even though there isn't a single shred of direct experimental data that confirms that model. At the heart of this issue is the foundational beliefs about the interaction of elementary charged particles and the reality is that people believe that like charged particles repel one another and the oppositely charged particles are attractively interactive. This is true and the forces between particles are expressed by Coulomb's Law; yet it is only true when elementary charge particles are not overlapping in the same momentum space (it is true only when charged particles have a significant amount of relative motion, so much that they are not in the same momentum space). Almost all of our experimental data is extracted from situations where the interacting particles have lots of relative motion. When elementary charged particles are at rest with respect to each other then their interactive behavior can be predicted to be just opposite to the expectations of Coulomb's Law. Most people, most physicists are completely unaware of this yet we have a lot of experimental data where same charged particles are snuggly bound to each other. This occurs in superconduction where tightly bound pairs of spin up / spin down electrons actually are responsible for the superconduction phenomenon itself. We have 60 year old data that shows that nuclear fusion occurs between nuclei that where none of the interacting nuclei had sufficient energy to surmount the so-called 'Coulomb Barrier'. We are not successful in building a nuclear fusion reactor because fusion doesn't work the way that all of our textbooks say that it does. There's no amount of money that can make it work opposite to the actual foundational principles (even if unknown to mankind). Not $5 billion nor even $5 trillion can get it to work if it doesn't actually work the way that they believe that it works.

    An Ohio State research group says "the typical approach to cone-guided Fast Ignition" won’t work. Here's the link:

    Meanwhile the Livermore, PLS page says basically the opposite:

    "The fast ignition approach holds the promise of reduced laser driver
    energy and increased fusion energy gains, exceeding gains of 100, and
    thus offers a potentially attractive pathway toward an eventual inertial
    fusion energy plant.". Here's the link:


  • Paul Maher

    Hey Guys, As it turns out there are far more ways to extract energy than there are to skin a cat, catfish that is. Here's 35 of them. They are not all proven, but neither is Hot Fusion. They are all one heck of a lot more scalable.


    With updates, 9/10/14

    When you take into account the amount of money that is spent on energy in the US annually, approximately 6-8 Trillion dollars, that's, 200 quads at an equivalent of 8 Billion gallons of gas per Quad. These numbers were extracted from the Energy Information Agency, the EIA. They did not make it easy to get to. There were far to many different units of measurement used, BTU's to Mega Joules, and everything in between , along with missing and irrelevant data, but it has been verified by at least one other independent analyst. It is easy to see how much resistance the oil companies and the Nuclear power folks might muster.

    Much of this may be new to you. I understand that, but please consider these things. You want innovation that will change the face of the planet? I think that at last count 656 patent applications can be viewed for LENR alone. On another note I added number 17, not because it generated excess energy, but because it's just damned neat that plasma is so easy to generate.

    Additionally there is much info available through a DOE sanctioned site on all of these birds. Also for papers and abstracts. And here is a website put together by the leaders of the LENR Pack,

    Come on Already!! It may very well be that not all of these advances will ever come to fruitiion. However at the rate new approaches to energy production are coming to the surface I am reminded of an old adage, "What man can conceive, man can achieve.". About 1 per month is showing up currently. I am betting that at least 1/2 of these birds can power a new and extraordinarily interesting world. Maybe all of them! Do not dismiss these birds.

    Now here is the deal, this rattles me a little.

    I ran actoss a presentation made to the Nobel Prize People on Thermionics in 1929. He was over unity. In that paper the term "Perpetuum Mobile" was used. I thought I would google it. People around the world have built so many interesting devices, motors, that ran all by themselves, using MANY curious phenomena Not the least of which is this one. . The big money guys do not give one damn dam about you, me, or the rest of mankind. They may take big write offs because they put on an obfuscatory show of being benefactors, but they cling to that which is killing the earth. I'm a little rattled!

    It's gotta be on this list, and the list is growing

    1. Cold Fusion, also known as Low Energy Nuclear Reactions, Lattice Assisted Nuclear Reactions, Controlled Electron Capture Reaction. These technologies are all about forcing Hydrogen or Deuterium atoms into the crystal lattice of a metal such as Nickel. Once the crystal lattice of the metal nano powder has been sufficently saturated with Hydrogen excess heat is generated. This is not hard to see, as everything is still vibrating, but now all the atoms are in much closer proximity than before. The quanta mechanical explanations are not fully understood, but there are several companies and government offices that have operational devices. Good bye oil. Google LENR, NASA, Zawodny, and Bushnell. NASA loves it. Checkout this youtube video from NASA. The big question is why the DOE is dragging their heels. This is the Federation of American Scientist

    Do a quick search at the above site for "LENR" The Indians are on it.

    2. Dense Plasma Focus goes something like this. Two cylindrical electrodes are enclosed in a glass tube after one electrode is slipped inside the other. The tube is then filled with Boron gas and high voltage is applied to the electrodes. A plasma is then produced and pulsed by a strong magnetic field. As this pulsing is increased and focused the plasmoids begin to ball up on one another. As pulsing continues a beam of electrons emanates from one end of the tube and a beam of protons from the other, with extremely high amounts of energy being produced. Google Charles Chase, Skunk Works, and Dense Plasma Focus. Watch Charles Chase on youtube.

    3. Catalyzed Hydrogen is what will replace Electrolysis. Molybdenum Sulfide is but one of the substances that will trim the Hydrogen right off the water molecule with no energy being expended, releasing it to power a fuel cell and generate electricity directly. There was a graduate student by the name of Chang working in Berkeley CA on this a couple of years ago.

    4. Graphene is essentially one atom thick layers of Carbon alternated between layers of insulation, such as mylar. When you get a bunch of these layers stacked up and attach electrodes to the top and bottom of the stack you have created a capacitor of another color. Extremely high values of capacitance can be arrived at. 3000 farads is what I have seen advertised, the size of a marine battery. This material can be used as a capacitor, a spectacular new form of battery, or configured as an extremely efficient solar cell. Additionally I have recently heard of work aimed at producing LENR in a Graphene environment. Ampenergo is a company that I think licensed this technology from the government. I want so much for Elon Musk to incorporate this into his new models. Not quite sure where to put this one.

    5. Zero Point Energy/Energy of the Vacuum used to be a little far out for me, but now I think I've got a cursory handle on it. The process on a Quantum level is much like the process that produces Ball Lightening. When tectonic plates shift causing an earth quake occasionallly something called Ball Lightening happens. Only in Zero Point it is what happens when an Orthorhombic plane from another dimension intersects our dimension and causes a disruption, releasing energy. Here's a Moray B. King video from the Breakthrough Energy Movement.

    Also a piece straight from NASA discussing something call an EmDrive utilizing RF energy at 935 Mhz to interact with the Energy of the Vacuum.

    6. Acoustic Cavitation/Bubble Fusion/Sonofusion. I am not sure at all how to say anything about this, but there is a great deal published about the possibility of deriving energy using this phenomenon.

    7. Muon catalyzed Fusion. Oh this is a good one!! Fermi Lab and SLAC developed a coherent beam of Muon's a couple of years ago. They shoot it into Hydrogen or Deuterium gas, and because the Muons have a negative charge equal to an electron, but are 207 times more massive than an electron they knock the electrons out of their shells around the Nucleus and the Fusion is made to happen in the atoms Nucleus. I don't know how many electron shells a beam can penetrate. But I'm betting it is more than one. Pretty good stuff…

    8. HALOGEN-CATALYSED COLD NUCLEAR FUSION, yet another, not quite as much info available for this flavor.

    9. Thermionic Power Generation/Thermoelectric, I heard about this just the other day. It may be that this technology will be a prime player. The devices turn heat from the sun, or anything else directly into electricity, instead of using light as photovoltaic solar cells do.

    I don't quite get it, but here is a patent from 1981 for this technology. I think NOW is the time for it to rise to the occasion.

    10. LENR with Zeolites, And of course the loading of zeolite with hydrogen, or deuterium gas

    You've got to love these guys. I would think that this would have to be one of the most easily demonstrated methods of cold fusion. At least if you believe these two fellows.

    11. Papp Engine. As it turns out plasma is pretty simple to make. Anyone can do it with a 12 V battery. Ever seen a simple spark while you were giving yourself a jump start to your automobiole? Within the spark, taking into account that 1% of the atmosphere is composed of Nobel gases, which go to the Plasma state within the spark.

    There are no magnets to confine the plasma once it is formed, so it is allowed to expand and drive a piston. My explanation is my own, but I think its close.

    12. Bloom Box. I don't know how I missed this one. All the big money is going HERE. The video is from 60 minutes a couple of years ago. Things are on a roll here with what looks like a jump for fuel cells. It amounts to thin wafers of Silicon that have been coated with different materials on each side and then stacked, much as the way you would stack Graphene layers upon one another.

    From what is said on 60 minutes these things are being deployed at major .com outfits in Silicon Valley.

    13. BlackLight Power Hydrino machine. OK, we're at a bakers dozen now, what the heck is going on. 10MW of electricity out of 1 cu. ft. package!!??

    The following is a caption under an illustration at the above website.

    SF-CIHT Cell Generates Electricity Directly from Water Freely Available in the Humidity in the Air

    14. Steorn Machine. They say that this new kind of electric generator has been duplicated by a number of organizations. A key fundemental cited is "Magnetic Regauging" Ferrite materials figure in as well. I actually have some experience using ferrite material. I built Isolators and circulators for military microwave applications. Biasing a ferrite puck with magnets causes microwave energy to flow in a circular manner within the ferrite. Reverse the magnetic polarity and energy flows in the opposite direction. While I was working in the field as a technician I was told that the phenomenon was not 100% understood. Perhaps it is now. Additionaly I witnessed a couple of folks producing a little bit different kind of sintered ferrite material in the late 80's that turned out to be high temperature super conducting material. It's the symmetry of a magnetic circuit that has been the thing that has been in the way. They say they have created a means of creating a constantly asymmetrical magnetic circuit. Or, something like that. Holy Smokes it's beginning to make sense to me! On a personal note, about 30 years ago I had recurrent dreams of a machine very much like this one. A little spooky!

    15. Hydrobetatron. The best information that I have seen so far paints it as another flavor of LENR, BUT IT IS OPEN SOURCED!!

    16. The Stirling Engine If this isn't a show stopper, I don't know what it is!!

    17. Multiplaz Welding and Cutting Tool, This doesn't generate excess heat, but it uses tap water and alcohol to make a heck of a plasma cutter. The fact that Plasma can so easily and cheaply produced is what I find interesting.

    18. Optical Rectification The deal here is essentially that they have tapped the electromagnetic nature of light. After all, different colored lights have different wavelenghts and therefore different frequencies. Everything from DC to daylight and beyond is what makes up the electromagnetic spectrum. They have now figured out how to rectify these extremely high frequencies and produce direct current electricity. You rectify 60 cycle AC when you build an electrical bridge circuit of diodes to convert it to DC. Optical Rectification is a Quantum kind of thing. I'm not quite sure where to put this one.

    19. Thermophotovoltaics

    20. Photoswitching This amounts to a hinged nanomolecular construct that switches from one state to the other on demand releasing energy. When the sun isn't out rechargeable solar batteries use a small electric current or a small light to start the switching back to the other state. There is some plumbing involved and a liquid medium holds thr charge.

    21. Ryden dual carbon battery

    22. Singlet Exiton Fission A new approach to Solar Cells

    23. Thorium Molten Salt Reactor I have resisted this one, but I couldn't tell you why. I have not seen scalability yet. Al Opdenaker likes this one. The best!!

    24. Vanadium Redox-flow Battery

    25. Artificial Leaf Straight from MIT

    26. Thermionic Self Charging Graphene Batteries, google "self charging batteries"!! The hybridization has begun.

    27. Piezoelectric self charging Batteries

    28. Magnetic Field Regauging Some of the stuff on this list is pretty wild. Some of the websites that discuss this topic are pretty hard to swallow, but the science is catching up with recent lab results and discoveries. A little time searching on google and you will start seeing the possibilities.
