Collaborate Disseminate
A newly introduced battery called the BV100 by Chinese Betavolt Technology promises to provide half a century of power, at 100 μW in a 15x15x5 mm package. Inside the package …read more Continue reading Betavoltaic Battery Rated To Provide Power For 50 Years
The Holy Grail of battery technology is a cell which lasts forever, a fit-and-forget device that never needs replacing. It may seem a pipe-dream, but University of Bristol researchers have …read more Continue reading The Thousand Year (Radioactive) Diamond Battery
Turn the clock back a couple of decades, and the only time the average person would have given much thought to batteries was when the power would go out, and …read more Continue reading Battery Engineering Hack Chat Gets Charged Up
[lasersaber] has a passion: low-power motors. In a bid to challenge himself and inspired by betavoltaic cells, he has 3D printed and built a small nuclear powered motor!
This photovoltaic battery uses fragile glass vials of tritium extracted from keychains and a small section of a solar panel to absorb the light, generating power. After experimenting with numerous designs, [lasersaber] went with a 3D printed pyramid that houses six coils and three magnets, encapsulated in a glass cloche and accompanied by a suitably ominous green glow.
Can you guess how much power and current are coursing through this thing? Guess …read more
