A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the Department of Energy’s Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources.

The goal is to enable power generation from low-temperature geothermal resources at an economical cost. In addition to being a clean energy source without any greenhouse gas emissions, geothermal is also a steady and dependable source of power.

“By the end of the calendar year, we plan to have a functioning bench-top prototype generating electricity,” predicts PNNL Laboratory Fellow Pete McGrail. “If successful, enhanced geothermal systems like this could become an important energy source.” A technical and economic analysis conducted by the Massachusetts Institute of Technology estimates that enhanced geothermal systems could provide 10 percent of the nation’s overall electrical generating capacity by 2050.

PNNL’s conversion system will take advantage of the rapid expansion and contraction capabilities of a new liquid developed by PNNL researchers called biphasic fluid. When exposed to heat brought to the surface from water circulating in moderately hot, underground rock, the thermal-cycling of the biphasic fluid will power a turbine to generate electricity.

To aid in efficiency, scientists have added nanostructured metal-organic heat carriers, or MOHCs, which boost the power generation capacity to near that of a conventional steam cycle. McGrail cited PNNL’s nanotechnology and molecular engineering expertise as an important factor in the development, noting that the advancement was an outgrowth of research already underway at the lab.

“Some novel research on nanomaterials used to capture carbon dioxide from burning fossil fuels actually led us to this discovery,” said McGrail. “Scientific breakthroughs can come from some very unintuitive connections.”

For a long time, batteries were bulky and heavy. Now, a new cutting-edge battery is revolutionizing the field. It is thinner than a millimeter, lighter than a gram, and can be produced cost-effectively through a printing process.

Printable batteries

In the past, it was necessary to race to the bank for every money transfer and every bank statement. Today, bank transactions can be easily carried out at home. Now where is that piece of paper again with the TAN numbers? In the future you can spare yourself the search for the number. Simply touch your EC card and a small integrated display shows the TAN number to be used. Just type in the number and off you go. This is made possible by a printable battery that can be produced cost-effectively on a large scale.

It was developed by a research team led by Prof. Dr. Reinhard Baumann of the Fraunhofer Research Institution for Electronic Nano Systems ENAS in Chemnitz together with colleagues from TU Chemnitz and Menippos GmbH. “Our goal is to be able to mass produce the batteries at a price of single digit cent range each,” states Dr. Andreas Willert, group manager at ENAS.

The characteristics of the battery differ significantly from those of conventional batteries. The printable version weighs less than one gram on the scales, is not even one millimeter thick and can therefore be integrated into bank cards, for example. The battery contains no mercury and is in this respect environmentally friendly. Its voltage is 1.5 V, which lies within the normal range. By placing several batteries in a row, voltages of 3 V, 4.5 V and 6 V can also be achieved. The new type of battery is composed of different layers: a zinc anode and a manganese cathode, among others. Zinc and manganese react with one another and produce electricity. However, the anode and the cathode layer dissipate gradually during this chemical process. Therefore, the battery is suitable for applications which have a limited life span or a limited power requirement, for instance greeting cards.

The batteries are printed using a silk-screen printing method similar to that used for t-shirts and signs. A kind of rubber lip presses the printing paste through a screen onto the substrate. A template covers the areas that are not to be printed on. Through this process it is possible to apply comparatively large quantities of printing paste, and the individual layers are slightly thicker than a hair. The researchers have already produced the batteries on a laboratory scale. At the end of this year, the first products could possibly be finished.

In revisiting a chemical reaction that’s been in the literature for several decades and adding a new wrinkle of their own, researchers with Berkeley Lab and the University of California (UC) Berkeley have discovered a mild and relatively inexpensive procedure for removing oxygen from biomass. This procedure, if it can be effectively industrialized, could allow many of today’s petrochemical products, including plastics, to instead be made from biomass.

“We’ve found and optimized a selective, one-pot deoxygenation technique based on a formic acid treatment,” said Robert Bergman, a co-principal investigator on this project who holds a joint appointment with Berkeley Lab’s Chemical Sciences Division and the UC Berkeley Chemistry Department.

The formic acid, Bergman said, converts glycerol, a major and unwanted by-product in the manufacturing of biodiesel, into allyl alcohol, which is used as a starting material in the manufacturing of polymers, drugs, organic compounds, herbicides, pesticides and other chemical products. Allyl alcohol today is produced from the oxidation of petroleum.

Said Jonathan Ellman, a UC Berkeley chemistry professor and the other principal investigator in this research, “Right now, about five percent of the world’s supply of petroleum is used to make feedstocks that are synthesized into commodity chemicals. If these feedstocks can instead be made from biomass they become renewable and their production will no longer be a detriment to the environment.”

Biomass has been drawing wide public attention for its potential to be converted into carbon-neutral biofuels, but there is also huge potential for it to be converted into chemical feedstocks. It is safe to say that a day does not go by without each of us making use of multiple petrochemical products. Feedstocks for such products obtained from biomass rather than petroleum would be renewable as well as biodegradable. However, unlike petrochemical feedstocks, which are made by adding oxygen to petroleum, biomass feedstocks require the removal of oxygen from the raw material.

Bergman and Ellman, working with Elena Arceo, a Fulbright scholar from Spain, and Peter Marsden, a UC Berkely graduate student, used labeling experiments and a unique distillation system to take a new look at an old chemical reaction in which formic acid, the chemical found in bee venom, was used to remove oxygen from glycerol. In its original conception, the reaction was low-yielding, primarily because of substantial charring, an unselective combustion that leads to an intractable mixture under high heat. Bergman and Ellman found that simply protecting this reaction from air provided a much improved process for the deoxygenation of glycerol.

Said Bergman, “Treating glycerol with formic acid while directing a stream of nitrogen through the reaction mixture completely eliminates charring. Besides protecting the product from atmospheric oxidation, the nitrogen also facilitates distillation of the alcohol. The final product shows substantially improved yield (80-percent) and higher selectivity.”

Said Ellman, “From our studies we also gained a much better understanding of the basic chemistry behind the reaction. We thought that the charring was a random oxidation process because the reaction had been carried out in air and we expected that running it in a nitrogen environment would improve things. However, in studying the basic chemistry we uncovered an unexpected reaction pathway that really broadens the generality of this reaction and expands its potential applications.”

With this new reaction pathway, the formic acid-mediated deoxygenation technique developed by Bergman and Ellman could be used to convert the carbohydrates in biomass, as well as other polyhdroxy compounds, into the chemical feedstocks, such as olefins (alkenes) that are now derived from petroleum. The technique could also prove useful in the process by which biomass is converted into liquid transportation fuels.

Said Bergman, “Our preliminary results with inexpensive biomass-derived polyols suggest that the reaction of polyhydroxy compounds with formic acid will be a valuable alternative for the manufacture of reduced oxygen content products. However, scaling this technique up so that biomass feedstocks are competitive with feedstocks derived from petroleum is going to be an engineering challenge.”

Added Ellman, “Scaling the technique up to industrial levels is probably going to require the combined efforts of industrial and academic laboratories, but if we are able to one day make commodity chemicals as well as fuels from biomass, we can protect the atmosphere from further damage and at the same time help lower current carbon dioxide levels.”

The concept of using road surfaces to generate clean solar power is already moving beyond the idea stage. Roads absorb heat from the sun every day and are usually free of sightline obstructions that could otherwise block the transmission of light rays. And if the roads built for cars and driving are partly to blame for global warming, why not make them part of the solution too?

Idaho Company Pioneers Using Roads to Generate Solar Power
Idaho-based company Solar Roadways is one of the trailblazers. Electrical engineer Scott Brusaw was inspired to start the company when he heard Caltech solar energy expert Nate Lewis suggest that covering just 1.7 percent of the continental U.S. land surface with photovoltaic solar collectors could produce enough power to meet the nation’s total energy demand.

US Interstate Highways Could Produce Enough Solar Power for the Whole World
Brusaw put two and two together when he realized that the interstate highway system already covers about that much of the nation’s land surface, so he got to work designing a system that combines a durable and translucent glass road surface with photovoltaic solar collectors that could be wired directly into the electricity grid. Brusaw’s innovative design would also heat the roads in winter, thus providing an important safety benefit.

With improvements in the efficiency of solar collectors in recent years, Brusaw believes his system, if implemented from coast-to-coast in place of the tarmac on existing highways, could produce enough energy to meet the electricity needs of the entire world.

Solar Roads Prototype Undergoing Endurance and Feasibility Tests
But skeptics wonder whether such an expensive high-tech road surface can stand up to the rigors of everyday use—from overloaded 18-wheelers putting extra stress on the highway to oil spills seeping into expensive electronic circuitry—without having to be replaced or repaired often. Brusaw acknowledges that his system still needs fine-tuning, but in the meantime he is developing a working prototype along a 45-mile stretch of road between the Idaho cities of Coeur D’Alene and Sandpoint.

Solar Roads in the UK Reduce Accidents
Europeans are also pioneering ways to put the sun’s rays to work as they beat down on roadways. The British firm Astucia has developed a road stud that contains small solar panels and emits LED light to illuminate dark roadways. On the 120 U.K. roads where the new studs have been installed, nighttime accidents are down some 70 percent.

Excess Solar Power from Roads Used to Heat Buildings
And the Dutch firm Ooms Avenhorn Holding BV has developed a way to siphon solar heat from asphalt road surfaces and use it to de-ice roads and to help power nearby buildings. A latticework of pipes under the road surface allows water to heat up during warm weather. The water is then pumped deep underground where it maintains its higher temperatures and can be retrieved months later to keep road surfaces ice-free during winter months. Apartment buildings, industrial parks and an Air Force base have benefited from the innovation, and the firm is working on exporting its system to other countries in the coming years.

BRUSSELS (AFP) – EU leaders on Thursday postponed a decision on climate change aid for the poorest nations, a move slammed by environmentalists.

“The main principles of contribution should be the ability to pay and the responsibility for emissions,” the European leaders said in a statement issued during a summit in Brussels

“All countries, except the least developed, should contribute to the financing of the fight against climate change in developing countries,” the text added.

But there were no concrete commitment or firm figures.

The EU “recognises the scale of the effort required” and would therefore contribute “a fair share of international public support for action for mitigation and adaptation, in particular for the least developed coutries,” the 27 heads of state and government said in their statement.

They invited the European Commission, the EU’s executive arm, to put forward proposals, including on financing “as soon as possible” so that decisions can be taken at the next EU summit in October.

In its own backyard, EU nations have committed to reducing greenhouse gas emissions by 20 percent from 1990 levels by 2020, and to increase the cuts to 30 percent if other developed countries follow suit.

Environmental group Greenpeace slammed the EU’s failure to put cash on the table to help developing countries to introduce green technologies and energy efficiencies.

“Money is the make or break issue in the ongoing global climate negotiations. Waiting until October means another three months of deadlock in international negotiations,” said Greenpeace’s EU climate and energy policy director Joris den Blanken.

“Today has shown us that European leaders are still not up to the challenge. We need European leadership to push for a strong climate deal by the end of this year,” he added, referring to global climate change talks in Copenhagen in December.

BRUSSELS (AFP) – EU leaders on Thursday postponed a decision on climate change aid for the poorest nations, a move slammed by environmentalists.

“The main principles of contribution should be the ability to pay and the responsibility for emissions,” the European leaders said in a statement issued during a summit in Brussels

“All countries, except the least developed, should contribute to the financing of the fight against climate change in developing countries,” the text added.

But there were no concrete commitment or firm figures.

Environmental group Greenpeace slammed the EU’s failure to put cash on the table to help developing countries to introduce green technologies and energy efficiencies.

Zero Point Energy Motor

When this zero point energy motor works and made available for public, the world will chance. Imagine what we can do with this motor. We can build it in our in homes and cars. No more need to make big and expensive batteries to ride electric cars. Probably a significant drop of pollution. We even could minimise the motor to smaller scale so it will fit into laptops, cellphone and other electronics, so they will never die. It’s also the perfect solution for providing electricity where there is no power grid.

What is Zero Point Energy

The Zero Point Energy (ZPE) is an intrinsic and unavoidable part of quantum physics. The ZPE has been studied, both theoretically and experimentally, since the discovery of quantum mechanics in the 1920s and there can be no doubt that the ZPE is a real physical effect. The “vacuum energy” is a specific example of ZPE which has generated considerable doubt and confusion. In a completely empty flat universe, calculations of the vacuum energy yield infinite values of both positive and negative sign–something that obviously does not correspond to the nature of the real world.

Observation indicates that in our universe the grand total vacuum energy is extremely small and quite possibly exactly zero. Many theorists suspect that the total vacuum energy is exactly zero.

It definitely is possible to manipulate the vacuum energy. Any objects that change the vacuum energy (electrical conductors, dielectrics and gravitational fields, for instance) distort the quantum mechanical vacuum state. These changes in the vacuum energy are often easier to calculate than the total vacuum energy itself. Sometimes we can even measure these changes in the vacuum energy in laboratory experiments.

In classical physics, if you have a particle that is acted on by some conservative force, the total energy is

E = (1/2) m v**2 + V(x).
To find the classical ground state, set the velocity to zero to minimise the kinetic energy, (1/2)m v**2 , and put the particle at the point where it has the lowest potential energy V(x) . But this result is only a classical approximation to the real world. Because the classical ground state completely specifies both the particle’s speed (zero) and position (at the minimum), it violates the famous Heisenberg Uncertainty Principle (m dv dx > hbar) . Quantum physics, via the Uncertainty Principle, forces the particle to spread out both in position and velocity and so causes it to have an energy somewhat higher than the classical minimum. The ZPE is defined as this shift:

E_(ZPE) = E_(quantum minimum) — E_(classical minimum) > 0.
Classically, we can calculate the natural oscillation frequency that the particle would have if we were to give it a small push. Quantum mechanically, it is now an undergraduate exercise to use the Heisenberg uncertainty relation (more precisely, Schroedinger’s differential equation) to show that

E_(ZPE) approx (1/2) hbar omega_0,
where hbar is Planck’s constant and omega_0 is the natural oscillation frequency. The ZPE in this sense shows up almost everywhere: it affects molecular bonds, condensed matter physics, small oscillations of any system.

The next step is to realise that the electromagnetic field can be thought of as an infinite collection of coupled oscillators–one at each point in space. Again, the classical ground state is the case in which the electric and magnetic fields both must be zero. Quantum effects mean that this case does not hold true; there is also a Heisenberg uncertainty principle for electric and magnetic fields (it’s a little more complex). The good news is that the potential for electromagnetism is exactly quadratic and so can be solved exactly. The bad news is that there is an infinite number of modes. Formally we can write

(Electromagnetic vacuum energy) = sum over all modes (1/2) hbar omega(mode).
The infinity in this equation is what excites the free lunch crowd (the modern descendants of the perpetual motion crowd), who envision an endless ZPE for humanity to tap into. Not quite. Unfortunately…

The first and most obvious problem is that there are other quantum fields in the universe apart from electromagnetism. Electrons, for starters, plus neutrinos, quarks, gluons, W, Z, Higgs and so on. In particular, if you do the calculation for electrons you will find that what are known as Fermi statistics give rise to an extra minus sign in the calculation.

Adding minus infinity to plus infinity gives mathematicians nightmares and even makes theoretical physicists worry a little. Fortunately, nature does not worry about what the mathematicians or physicists think and does the job for us automatically. Consider the grand total vacuum energy (once we have added in all quantum fields, all particle interactions, kept everything finite by hook or by crook, and taken all the proper limits at the end of the day). This grand total vacuum energy has another name: it is called the “cosmological constant,” and it is something that we can measure observationally.

In its original incarnation, the cosmological constant was something that Einstein put into General Relativity (his theory of gravity) by hand. Particle physicists have since taken over this idea and appropriated it for their own by giving it this more physical description in terms of the ZPE and the vacuum energy. Astrophysicists are now busy putting observational limits on the cosmological constant. From the cosmological point of view these limits are still pretty broad: the cosmological constant could potentially provide up to 60 percent to 80 percent of the total mass of the universe.

From a particle physics point of view, however, these limits are extremely stringent: the cosmological constant is more than 10**(123) times smaller than one would naively estimate from particle physics equations. The cosmological constant could quite plausibly be exactly zero. (Physicists are still arguing on this point.) Even if the cosmological constant is not zero it is certainly small on a particle-physics scale, small on a human-engineering scale, and too tiny to be any plausible source of energy for human needs–not that we have any good ideas on how to accomplish large-scale manipulations of the cosmological constant anyway.

Putting the more exotic fantasies of the free lunch crowd aside, is there anything more plausible that we could use the ZPE for? It turns out that small-scale manipulations of the ZPE are indeed possible. By introducing a conductor or a dielectric, one can affect the electromagnetic field and thus induce changes in the quantum mechanical vacuum, leading to changes in the ZPE. This is what underlies a peculiar physical phenomenon called the Casimir effect. In a classical world, perfectly neutral conductors do not attract one another. In a quantum world, however, the neutral conductors disturb the quantum electromagnetic vacuum and produce finite measurable changes in the energy as the conductors move around. Sometimes we can even calculate the change in energy and compare it with experiment. These effects are all undoubtedly real and uncontroversial but tiny.

More controversial is the suggestion, made by the physicist Julian Schwinger, that the ZPE in dielectrics has something to do with sonoluminescence. The jury is still out on this one and there is a lot of polite discussion going on (both among experimentalists, who are unsure of which of the competing mechanisms is the correct one, and among theorists, who still disagree on the precise size and nature of the Casimir effect in dielectrics.) Even more speculative is the suggestion that relates the Casimir effect to “starquakes” on neutron stars and to gamma ray bursts.

In summary, there is no doubt that the ZPE, vacuum energy and Casimir effect are physically real. Our ability to manipulate these quantities is limited but in some cases technologically interesting. But the free-lunch crowd has greatly exaggerated the importance of the ZPE. Notions of mining the ZPE should therefore be treated with extreme skepticism. Read the rest of this entry

A team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy. The team’s results one day could be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy.

The scientists found that the chlorophylls are highly efficient at harvesting light energy. “We found that the orientation of the chlorophyll molecules make green bacteria extremely efficient at harvesting light,” said Donald Bryant, Ernest C. Pollard Professor of Biotechnology at Penn State and one of the team’s leaders. According to Bryant, green bacteria are a group of organisms that generally live in extremely low-light environments, such as in light-deprived regions of hot springs and at depths of 100 meters in the Black Sea. The bacteria contain structures called chlorosomes, which contain up to 250,000 chlorophylls. “The ability to capture light energy and rapidly deliver it to where it needs to go is essential to these bacteria, some of which see only a few photons of light per chlorophyll per day.”

Because they have been so difficult to study, the chlorosomes in green bacteria are the last class of light-harvesting complexes to be characterized structurally by scientists. Scientists typically characterise molecular structures using X-ray crystallography, a technique that determines the arrangement of atoms in a molecule and ultimately gives information that can be used to create a picture of the molecule; however, X-ray crystallography could not be used to characterise the chlorosomes in green bacteria because the technique only works for molecules that are uniform in size, shape, and structure. “Each chlorosome in a green bacterium has a unique organization,” said Bryant. “They are like little andouille sausages. When you take cross-sections of andouille sausages, you see different patterns of meat and fat; not two sausages are alike in size or content, although there is some structure inside, nevertheless. Chlorosomes in green bacteria are like andouille sausages, and the variability in their compositions had prevented scientists from using X-ray crystallography to characterise the internal structure.”

To get around this problem, the team used a combination of techniques to study the chlorosome. They used genetic techniques to create a mutant bacterium with a more regular internal structure, cryo-electron microscopy to identify the larger distance constraints for the chlorosome, solid-state nuclear magnetic resonance (NMR) spectroscopy to determine the structure of the chlorosomes component chlorophyll molecules, and modelling to bring together all of the pieces and create a final picture of the chlorosome.

First, the team created a mutant bacterium in order to determine why the chlorophyll molecules in green bacteria became increasingly complex over evolutionary time. To create the mutant, they inactivated three genes that green bacteria acquired late in their evolution. The team suspected that the genes were responsible for improving the bacteria’s light-harvesting capabilities. “Essentially, we went backward in evolutionary time to an intermediate state in order to understand, in part, why green bacteria acquired these genes,” Bryant said. The team found that the more evolved, wild-type bacteria grow faster at all light intensities than the mutant form. “Indeed, the reason that chlorophylls became more complex was to increase light-harvesting efficiency,” said Bryant.

Next, the team isolated chlorosomes from the mutant and the wild-type forms of the bacteria and used cryo-electron microscopy — a type of electron microscopy that is performed at super-cold cryogenic temperatures — to take pictures of the chlorosomes. The pictures revealed that chlorophyll molecules inside chlorosomes have a nano tube shape. “They are like Russian dolls, with one concentric tube fitting inside the next,” said Bryant. “The mutant bacterium’s chlorosomes contain only one set of tubes, whereas the wild-type chlorosomes contain many tubes, each arranged in a unique pattern, like those andouille sausages.”

The team then went a step further and used solid-state NMR spectroscopy — a technique in which samples are spun very rapidly and exposed to a magnetic field — to look deep inside the chlorosome. This technique enables researchers to understand the relationships between atomic nuclei in a sample and, ultimately, to acquire structural information about the molecules of interest.

“The NMR data revealed to us that the individual chlorophyll molecules in green bacteria are arranged in dimers — molecules consisting of two identical simpler molecules — with their long hydrophobic, or water-repellent, tails sticking out of either side,” said Bryant. “We also learned precisely how the chlorophyll molecules attach to one another, and we were able to measure the distance between chlorophyll molecules. The cryo-electron microscopy pictures showed gross structural details and distances, and the NMR results allowed us to quantify these distances as well, and confirmed to us that what were nano tubes seeing was, in fact, stacks of the chlorophyll molecules all lined up,” he said. The NMR results also enabled the scientists to determine that the chlorophyll molecules in green bacteria are arranged in helical spirals. In the mutant bacteria, the chlorophyll molecules are positioned at a nearly 90-degree angle in relation to the long axis of the nano tubes, whereas the angle is less steep in the wild-type organism. “It’s the orientation of the chlorophyll molecules that is the most important thing here,” said Bryant. The last steps for the team were to pull together all of their data and to create a detailed computer model of the structure.

“At first it seems counterintuitive that green bacteria have managed to evolve a better light-harvesting system by increasing disorder in the chlorosome structure,” said Bryant. “Most people would think that if you make something that is more highly ordered, you’ll end up with something that works better. But this is clearly a case where that isn’t true. If all of the chlorophyll’s are identically arranged in a chlorosome, then the energy from the photon, once it is absorbed, is going to wander around over all of those chlorophyll’s, which could take a long time. In the wild-type form, you have these different domains where chlorophyll molecules are located and, therefore, the ability of photon energy to migrate becomes restricted. In other words, the energy in an individual photon visits a smaller number of chlorophylls, and that’s an advantage to the organism because the energy can get to where it needs to go faster. Speed is the name of the game that green bacteria play with light. The organisms have only a couple of nanoseconds for the energy to get someplace useful or else the energy is going to be lost. The speed required can be a problem for bacteria that receive only a few photons of light per chlorophyll per day.”

Bryant said that the team’s results may one day be used to build artificial photosynthetic systems that convert solar energy to electricity. “The interactions that lead to the assembly of the chlorophyll’s in chlorosomes are rather simple, so they are good models for artificial systems,” he said. “You can make structures out of these chlorophyll’s in solution just by having the right solution conditions. In fact, people have done this for many years; however, they haven’t really understood the biological rules for building larger structures. I won’t say that we completely understand the rules yet, but at least we know what two of the structures are now and how they relate to the biological system as a whole, which is a huge advance.”

The team also includes researchers from the Leiden Institute of Chemistry and the Groningen Biomolecular Sciences and Biotechnology Institute in the Netherlands, and the Max Planck Institute in Germany. This research was supported by the United States Department of Energy.

Ask nearly any physicist if it’s possible for a hydrogen atom to enter a lower energy state than the ground, or resting state they hold in nature, and you’re likely to get an unequivocal “no.” But a tiny company in New Jersey called Blacklight Power has been disputing that assumption for over a decade, and of late, making gadfly claims that its founder says will overturn the accepted scientific order.

To a regular person, of course, disputes between physicists are boring at best. But Blacklight’s claims have a special significance: If they’re true, that means there’s a source of cheap, clean energy that can be easily tapped anywhere in the world. And rather than attempt to convince the world with calculations, Blacklight now says that it has physical proof in the form of its energy generator, verified by an independent university lab.

It’s difficult to get one’s hopes up, though. Scientific history is littered with ambitious, revolutionary theories that turned out to be groundless. But Blacklight is an interesting case. Its “hydrino” theory isn’t put forth by a single crackpot. Instead, the company employs a good handful of high-level scientists who would presumably rebel if the idea was totally false. It has also taken over $60 million in venture funding. Despite a hearty rejection by the scientific mainstream, and being ignored for years on end, its founder, Randell Mills, has plugged on. We covered the company extensively back in May, when it started saying it had a prototype 50 kilowatt reactor.

At the time, Mills was reluctant to provide much proof, saying only that the process was being verified. Now an engineering team at Rowan University, also in New Jersey, has come forward with results from its own tests of the Blacklight process. Tests conducted in sealed chambers, and measured with a device called a calorimeter, show a heat reaction from a substance provided by Blacklight far beyond anything anticipated.

Blacklight is providing the Rowan researchers with a common industrial form of nickel called Raney nickel, which is then put through a reaction with water to produce energy. “We’ve been able to regularly reproduce these results and we believe any research lab could do the same,” Peter Jansson, the faculty member heading the experiments.

There’s one odd factor in Jansson’s tests, which is that Blacklight supplies the Raney nickel, which it in turn obtains from an industrial supplier. When I asked, Jansson wasn’t sure what, if anything, Blacklight did to prepare the material, but Mills was happy to tell me in a separate interview that it’s doped with a very small amount of another common material, sodium hydroxide, in a process that others could replicate.

Jansson, for his part, said that the chemists on his team who analyzed the material couldn’t see any clear way that Blacklight might have rigged the tests by somehow storing energy in the Raney nickel. “It would be rather difficult to do this quantity of heat storage chemically in this material,” said Jansson. “We would have seen significant changes.”

It should be noted that Jansson has been aware of Blacklight for years, and even acted as an advisor for an energy company that ultimately made a strategic investment, but it appears to have no unethical ties, just an ongoing interest. Jansson also professes to be impartial to the existence of hydrinos, saying he’s interested in hearing any “alternative explanation” to the hydrino theory. Mills, for his part, says that he’d like for scientists to independently verify every step of the process, from obtaining the Raney nickel and doping it to the calorimeter tests to prove that the energy bursts really exist. The information needed to run those tests is free to the public, he says; the only thing required is a researcher willing to take the time to puzzle through the process.

Unfortunately, the reactions Jansson’s team is observing produce only a quick burst of intense heat. In a commercialized process, there needs to be a steady output. Mills says he has purposefully kept knowledge of how to loop the reaction within the company, so that his own researchers can remain a step ahead in their work on the 50KW reactor the company earlier announced.

According to Mills, it’s likely that a totally independent researcher will verify the whole process within a year. Meanwhile, the company will start licensing out its energy process, and do work with hydrinos in various chemical applications.

It would be odd if Blacklight were a complete sham for Mills to place himself in an end game in which he would be definitively proven wrong within just a year or two. So there does seem to be something deeper here. Physicists will still deny the hydrino theory, and they may be right; perhaps that’s why there was a distinct note of smugness in Mills’ voice as he said, “The controversy and academic debate won’t stop commercialization.”

What evidence there is, Mills calls “totally unequivocal,” although it seems prudent to wait for more independent verifications to emerge for what Mills himself calls the most important energy breakthrough since the discovery of nuclear power.
