Brilliant Light Power

By 2008, Park continued to express his skepticism:

"BlackLight Power (BLP), founded 17 years ago as HydroCatalysis, announced last week that the company had successfully tested a prototype power system that would generate 50 KW of thermal power. BLP anticipates delivery of the new power system in 12 to 18 months. The BLP process, discovered by Randy Mills, is said to coax hydrogen atoms into a "state below the ground state", called the "hydrino". There is no independent scientific confirmation of the hydrino, and BLP has a patent problem. So they have nothing to sell but bull shit. The company is therefore dependent on investors with deep pockets and shallow brains." – Park In 2008, Robert L. Park wrote that BLP has benefited from wealthy investors who allocate a proportion of their funds to risky ventures with a potentially huge upside, but that in the case of BLP since the science underlying the offering was "just wrong" investment risk was, in Park's view, "infinite".

Various scientists also voiced their opinions as far back as the 1990s. Steven Chu, Nobel Laureate in Physics in 1997, said "it's extremely unlikely that this is real, and I feel sorry for the funders, the people who are backing this". In 1999, Princeton University's physics Nobel laureate Phillip Anderson said of it, "If you could fuck around with the hydrogen atom, you could fuck around with the energy process in the sun. You could fuck around with life itself." "Everything we know about everything would be a bunch of nonsense. That's why I'm so sure that it's a fraud." Wolfgang Ketterle, a professor of physics at MIT, said BLP's claims are "nonsense" and that "there is no state of hydrogen lower than the ground state". Michio Kaku, a theoretical physicist based at City University of New York, adds that "the only law that this business with Mills is proving is that a fool and his money are easily parted." and that "There's a sucker born every minute." While Peter Zimmerman was chief arms-control scientist at the State Department, he stated that his department and the Patent Office "have fought back with success" against "pseudoscientists" and he railed against, among other things, the inventors of "hydrinos". In 2009, the editors of IEEE Spectrum magazine characterized it as a "loser" technology because "[m]ost experts don't believe such lower states exist, and they say the experiments don't present convincing evidence" and mentioned that Wolfgang Ketterle had said the claims are "nonsense". BLP has announced several times that it was about to deliver commercial products based on Mill's theories but has not delivered a working product.

Mark Chu-Carroll a science blogger and professional software engineer accused Mills of engaging in a scam: "Mills... is getting investors to give him money, promising that whatever they invest, they'll get back manifold when he starts selling hydrino power generators! He promises they'll be on market within a year or two – five at most! Then he comes up with either a demonstration, or the testimonial from his neighbor, or the self-publication of his book, or another press release talking about the newest version of his technology..... It's been going on for almost 25 years, this constant cycle of press release/demo/testimonial every couple of years.... claims from 2009 claiming commercialization within 12 to 18 months; from 2005 claiming commercialization within months; and claims from 1999 claiming commercialization within a year.... But he always comes up with an excuse why those deadlines needed to be missed. And he always manages to find more investors, willing to hand over millions of dollars. As long as suckers are still willing to give him money, why wouldn't he keep on making claims?"

Scientific American reported that in 2014, Mills was asked by an interested follower if he had ever isolated hydrinos and, in spite of previous claims, Mills said that he had not and that it would be "a really, really huge task." The interlocutor pointed out that if hydrinos were being produced at the rate Mills claimed, there would be obvious observations. Moreover, there was no sign of progress, "Every year they make up half the remaining distance to commercialization, but will they ever get there?"

In 2015, an energy analyst writing for Forbes noted that Mills had made numerous extraordinary and difficult-to-believe claims including that he had "refuted quantum mechanics, can explain "mysteries of the sun" and has identified dark energy. His inventions can: produce power very cheaply through "'shrinking' the hydrogen atom's orbitsphere" with a power density of 100 billion watts per liter. Additionally, the materials created can act as an explosive or propellant, make ships rustproof and endowed with stealth properties, produce an anti-gravity effect that will allow a vessel to elevate, and "form the basis of batteries the size of a briefcase to drive your car 1000 miles at highway speeds on a single charge.""

Peer-reviewed criticisms

In the 2000s, several reviewed articles were published criticizing Hydrino theory for being incompatible with Quantum Mechanics.

For example, in 2005, Andreas Rathke of the European Space Agency, publishing in the New Journal of Physics, wrote that Mills' description of quantum mechanics is "inconsistent and has several serious deficiencies", and that there is "no theoretical support of the hydrino hypothesis". Rathke said it would be helpful if Mills' experimental results could be independently replicated, and suggested that any evidence produced should be reconsidered in the context of a conventional physical explanation. One inconsistency of Mills' CQM with quantum mechanics regards its inability to be reconciled with the probability density function in quantum mechanics. Rathke stated, "However, while solutions of the Schrödinger equation with n<1 indeed exist, they are not square integrable. This violates not only an axiom of quantum mechanics, but in practical terms prohibits that these solutions can in any way describe the probability density of a particle." In the same year, the Journal of Applied Physics published a critique by A.V. Phelps of the 2004 article, "Water bath calorimetric study of excess heat generation in resonant transfer plasmas" by J. Phillips, R. Mills and X. Chen. Phelps criticized both the calorimetric techniques and the underlying theory described in the Phillips/Mills/Chen article. The journal also published a response to Phelps' critique on the same day. In 2005 Šišović and others published a paper describing experimental data and analysis of Mills' claim that a resonant transfer model (RTM) explains the excessive Doppler broadening of the Hα line. Šišović concluded that: "The detected large excessive broadening in pure hydrogen and in Ne–H2 mixture is in agreement with CM [Collision Model] and other experimental results" and that "these results can't be explained by RTM". The collision model explanation for excessive broadening of the Hα line is based on established physics.

In 2006, a paper published in Physics Letters A, concluded that Mills' theoretical hydrino states are unphysical. For the hydrino states, the binding strength increases as the strength of the electric potential decreases, with maximum binding strength when the potential has disappeared completely. The author Norman Dombey remarked "We could call these anomalous states "homeopathic" states because the smaller the coupling, the larger the effect." The model also assumes that the nuclear charge distribution is a point rather than having an arbitrarily small non-zero radius. It also lacks an analogous solution in the Schrödinger equation, which governs non-relativistic systems. Dombey concluded: "We suggest that outside of science fiction this is sufficient reason to disregard them." From a suggestion in Dombey's paper, further work by Antonio Di Castro has shown that states below the ground state, as described in Mills' work, are incompatible with the Schrödinger, Klein–Gordon and Dirac equations, key equations in the study of quantum systems.

In 2008, the Journal of Physics D: Applied Physics published an article by Hans-Joachim Kunze, professor emeritus at the Institute for Experimental Physics, Ruhr University Bochum, critical of the 2003 paper authored by R. Mills and P. Ray, Extreme ultraviolet spectroscopy of helium–hydrogen. The abstract of the article is: "It is suggested that spectral lines, on which the fiction of fractional principal quantum numbers in the hydrogen atom is based, are nothing else but artefacts." Kunze stated that it was impossible to detect the novel lines below 30 nm reported by Mills and Ray because the equipment they used did not have the capability to detect them as per the manufacturer and as per "every book on vacuum-UV spectroscopy" and "therefore the observed lines must be artefacts". Kunze also stated that: "The enormous spectral widths of the novel lines point to artefacts, too."
