Nuclear battery: Chinese firm aiming for mass market production

The BV100 battery (Image: Betavolt)Beijing Betavolt New Energy Technology Company Ltd claims to have developed a miniature atomic energy battery that can generate electricity stably and autonomously for 50 years without the need for charging or maintenance. It said the battery is currently in the pilot stage and will be put into mass production on the market.Atomic energy batteries - also known as nuclear batteries or radioisotope batteries - work on the principle of utilising the energy released by the decay of nuclear isotopes and converting it into electrical energy through semiconductor converters.Betavolt, which was established in April 2021, says its battery "combines nickel-63 nuclear isotope decay technology and China's first diamond semiconductor (4th generation semiconductor) module to successfully realise the miniaturisation of atomic energy batteries".The company's team of scientists developed a unique single-crystal diamond semiconductor that is just 10 microns thick, placing a 2-micron-thick nickel-63 sheet between two diamond semiconductor converters. The decay energy of the radioactive source is converted into an electrical current, forming an independent unit. Betavolt said its nuclear batteries are modular and can be composed of dozens or hundreds of independent unit modules and can be used in series and parallel,...

Interesting stuff about Einstein

....... "Einstein Quotes and Interesting Facts: Assassination Lists, Autopsied Brains and Socks" by James Fenner Guardian Express: According to a new book, entitled Einstein and the Quantum, written by A. Douglas Stone, Albert Einstein’s contributions towards the various fields of science, and the extent of his genius, may have been significantly overlooked. Stone, who is the chair of Yale’s Department of Applied Physics, argues, such was the magnitude of Einstein’s phenomenal works, the man could have been “… worthy of four Nobel Prizes…” In reality, the remarkable physicist was only awarded a single Nobel Prize. Throughout his book, Stone waxes lyrical about Einstein, highlighting his many accomplishments, and talking about his advancement of numerous concepts in quantum theory, and garnering enormous recognition for his theory of relativity. Einstein was, of course, renowned for his work as a physicist. However, he also contributed a great deal to philosophy, with most of his philosophical reflections having been driven by academic study. A young philosopher, called Robert Thornton, after completing his Ph.D. at Minnesota, was due to begin teaching physics at the University of Puerto Rico. Before beginning histutelage, he wanted to combine both scientific and philosophical perspectives to present a modern physics...
