Machine learning (ML), a form of artificial intelligence that recognizes faces, understands language and navigates self-driving cars, can help bring to Earth the clean fusion energy that lights the sun and stars. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) are using ML to create a model for rapid control of plasma—the state of matter composed of free electrons and atomic nuclei, or ions—that fuels fusion reactions.
The sun and most stars are giant balls of plasma that undergo constant fusion reactions. Here on Earth, scientists must heat and control the plasma to cause the particles to fuse and release their energy. PPPL research shows that ML can facilitate such control.

Against all probability, a device that purports to use cold fusion to generate vast amounts of power has been verified by a panel of independent scientists. The research paper, which hasn’t yet undergone peer review, seems to confirm both the existence of cold fusion, and its potency: The cold fusion device being tested has roughly 10,000 times the energy density and 1,000 times the power density of gasoline. Even allowing for a massively conservative margin of error, the scientists say that the cold fusion device they tested is 10 times more powerful than gasoline — which is currently the best fuel readily available to mankind.
The device being tested, which is called the Energy Catalyzer (E-Cat for short), was created by Andrea Rossi has been claiming for the past two years that he had finally cracked cold fusion, but much to the chagrin of the scientific community he hasn’t allowed anyone to independently analyze the device — until now. While it sounds like the scientists had a fairly free rein while testing the E-Cat, we should stress that they still don’t know exactly what’s going on inside the sealed steel cylinder reactor. Still, the seven scientists, all from good European universities, obviously felt confident enough with their findings to publish the research paper.
As for what’s happening inside the cold fusion reactor, Andrea Rossi and his colleague Sergio Focardi have previously said their device works by infusing hydrogen into nickel, transmuting the nickel into copper and releasing a large amount of heat. While Rossi hasn’t provided much in the way of details — he’s a very secretive man, it seems — we can infer some knowledge from NASA’s own research into cold fusion. Basically, hydrogen ions (single protons) are sucked into a nickel lattice (pictured right); the nickel’s electrons are forced into the hydrogen to produce neutrons; the nickel nuclei absorb these neutrons; the neutrons are stripped of their electrons to become protons; and thus the nickel goes up in atomic number from 28 to 29, becoming copper.

ARPA-E-funded alternative z-pinch fusion which is being developed by Zap Energy.
Zap Energy is the most compact solution to Fusion Energy and does not use complex and costly magnetic coils. They surpassed ARPA-E Alpha Milestones in August 2018. Their reactor is consistently producing neutrons and they received $6.8 million ARPA-E OPEN funding.
The new Z-pinch has the simplest geometry of any magnetic confinement configuration. It is a cylindrical plasma column.

Cold Fusion 25 Years Later
Posted in nuclear energy, physics
Scientists discover source of clean, unlimited energy! In March 1989, the news rocked the world. Two respected chemists from the University of Utah: Martin Fleischmann and Stanley Pons, told a receptive media they had solved the biggest physics problem of the atomic age. Their compelling claims of room-temperature nuclear fusion in a jar were cast as the solution to the world’s colliding environmental and energy crises.
The meltdown hit just weeks later when the claim was nuked by mainstream scientists who couldn’t reproduce their results and were unsatisfied with the team’s explanations. The cold fusion field has been on ice ever since. Whether considered a scandal, a screw-up, or a scientific character assassination by hot fusion advocates, the cold fusion episode is a case study for those who caution against the “science of wishful thinking.”
On the 25th anniversary of the rise and fall of cold fusion, its close cousin, low-energy nuclear reaction (LENR) science, is still on the fringe but simmering anew. Here’s a look back and a look ahead at a field that always gets a reaction.

Ever since the 1989 debacle, cold fusion has been a byword for “junk science”—and cold fusion research has been anathema, tantamount to scientific suicide. Still, some quiet pioneers have continued the research, albeit under a changed name: LENR, or “low-energy nuclear reactions.” The jury’s still out on whether their methods will prove successful, but the race for inexhaustible “cold” fusion is definitely heating up.
