YouTube video: Brief Introduction to Cold Fusion

We have published a 6-minute video, A Brief Introduction to Cold Fusion. This video explains why we know that cold fusion is a real effect, why it is not yet a practical source of energy, and why it will  have many advantages if it can be made practical. The script for this video along with Explanatory Notes and Additional Resources is here.

ICCF19 was held in April 2015

The ICCF19 International Conference on Condensed Matter Nuclear Science was held in Padua, Italy, April 13 – 17, 2015. The conference website is here:

Here is an overview of the conference by David Nagel.

Levi et al. publish a second, extended report on Rossi reactor

The professors who published a report on Andrea Rossi’s high temperature reactor have followed up with second, extended test and a more detailed report:

Levi, G., et al., Observation of abundant heat production from a reactor device and of isotopic changes in the fuel. 2014, Bologna University. A copy is here.

Five outside experts in mass spectroscopy and related fields contributed four appendixes covering the radiation, materials, SIMS and ICP analyses. The research was sponsored by the Royal Swedish Academy of Sciences, Elforsk AB., Officine Ghidoni SA, and Industrial Heat LLC (USA).

This test produced 1.5 megawatt-hours of energy continuously, over 32 days. This is 5,825 MJ, or as much energy as you get from burning 139 kg of gasoline. This is a new record for a cold fusion reaction. Previous large reactions produced 50 to 300 MJ.

Michael McKubre reviewed the paper here.

Mats Lewan described the paper here.

Thomas Clarke reviewed that paper here, citing a number of errors.

Here is the Abstract and part of the conclusion:

New results are presented from an extended experimental investigation of anomalous heat production in a special type of reactor tube operating at high temperatures. The reactor, named E-Cat, is charged with a small amount of hydrogen-loaded nickel powder plus some additives, mainly Lithium. The reaction is primarily initiated by heat from resistor coils around the reactor tube. Measurements of the radiated power from the reactor were performed with high-resolution thermal imaging cameras. The measurements of electrical power input were performed with a large bandwidth three-phase power analyzer. Data were collected during 32 days of running in March 2014. The reactor operating point was set to about 1260ºC in the first half of the run, and at about 1400°C in the second half. The measured energy balance between input and output heat yielded a COP factor of about 3.2 and 3.6 for the 1260ºC and 1400ºC runs, respectively. The total net energy obtained during the 32 days run was about 1.5 MWh. This amount of energy is far more than can be obtained from any known chemical sources in the small reactor volume. A sample of the fuel was carefully examined with respect to its isotopic composition before the run and after the run, using several standard methods: XPS, EDS, SIMS, ICP-MS and ICP-AES. The isotope composition in Lithium and Nickel was found to agree with the natural composition before the run, while after the run it was found to have changed substantially. Nuclear reactions are therefore indicated to be present in the run process, which however is hard to reconcile with the fact that no radioactivity was detected outside the reactor during the run.

In summary, the performance of the E-Cat reactor is remarkable. We have a device giving heat energy compatible with nuclear transformations, but it operates at low energy and gives neither nuclear radioactive waste nor emits radiation. From basic general knowledge in nuclear physics this should not be possible. Nevertheless we have to relate to the fact that the experimental results from our test show heat production beyond chemical burning, and that the E-Cat fuel undergoes nuclear transformations. It is certainly most unsatisfying that these results so far have no convincing theoretical explanation, but the experimental results cannot be dismissed or ignored just because of lack of theoretical understanding. . . .

Magnus Olofsson, the CEO of Elforsk wrote about this paper in NyTeknik. He said (Google translation):

Elforsk has in recent years followed the development of what has come to be called nuclear reactions at low energy, LENR – Low Energy Nuclear Reactions. Elforsk include published a compilation of knowledge about LENR. Elforsk has also co-funded the current measurements and earlier measurements. While the earlier measurements showed an unexplained excess energy. . . .

Elforsk takes now the initiative to build a comprehensive Swedish research initiative. More knowledge is needed to understand and explain. Let us engage more researchers in searching [this] phenomenon and then explain how it works.

Here is the official statement about this paper at Elforsk’s website, in Swedish and English.

Mats Lewan reports on Rossi, and Defkalion

Reporter Mats Lewan of the Ny Teknik magazine has published a book about the cold fusion researcher Andrea Rossi. The book is titled An Impossible Invention. It is available in English, Swedish and Italian. You can read the first chapter or order the book here.

Nobel Laureate Brian Josephson published a comment at describing the book:

The highlight of the week was the publication of Mats Lewan’s book ‘An Impossible Invention’, subtitled The true story of the energy source that could change the world. The author, a science and technology writer, has been investigating the controversial Rossi reactor or E-cat in depth in the 3 years since its initial presentation in Bologna in January 2011.  . . 

Besides following the course of developments in detail, Lewan gives much attention to the question of whether the device is genuine, or whether fraud is involved. One important event was a long-period investigation [by ELFORSK], published at arXiv:1305.3913, providing strong evidence of the production of anomalous heat.  . . .

This fascinating book provides the answers to many questions about the E-cat, and should be read by all skeptics.

(Quoted in full here.)

In his blog about the book, Lewan revealed that the video demonstration test performed by Defkalion Green Technologies during the ICCF18 conference in July 2013 was invalid. The flow rate was measured incorrectly, because the flow meter was affected by backflow. Subsequent tests showed that the meter sometimes measured as much as 1 L/min when the valve was closed and flow was zero. The instruments indicate spurious excess heat of up to 17 kW where the actual power is 2.5 kW.

The video demonstration test was performed in Italy by a join-venture company Defkalion Europe (DE). Luca Gamberale of DE discovered the problems with the test and wrote about them in his Final technical report on the Defkalion GT calorimetric protocol. As described in the report, when DE discovered the problems, they “immediately stopped/froze all negotiations with both Italian and foreign companies to protect their clients.” DE is now defunct.

Lewan’s blog entry and his discussion with Gamberale reveals even more problems with Defkalion.

Swedish researchers have tested Rossi energy catalyst – E-cat

Researchers from Uppsala University and KTH Stockholm has conducted measurements of the produced heat energy from a device called the E-cat. It is known as an energy catalyst invented by the Italian scientist Andrea Rossi.

The measurements show that the catalyst gives substantially more energy than can be explained by ordinary chemical reactions. The results are very remarkable. What lies behind the extraordinary heat production can not be explained today. There has been speculation over whether there can be any form of nuclear transformation. However, this is highly questionable. To learn more about what is going on you have to learn what is happening with the fuel and the waste it produces. The measurements have been funded by such Elforsk.


Here is the abstract from this paper:

An experimental investigation of possible anomalous heat production in a special type of reactor tube named E-Cat HT is carried out. The reactor tube is charged with a small amount of hydrogen loaded nickel powder plus some additives. The reaction is primarily initiated by heat from resistor coils inside the reactor tube. Measurement of the produced heat was performed with high-resolution thermal imaging cameras, recording data every second from the hot reactor tube. The measurements of electrical power input were performed with a large bandwidth three phase power analyzer. Data were collected in two experimental runs lasting 96 and 116 hours, respectively. An anomalous heat production was indicated in both experiments.
