First Quantum Battery Prototype Marks Big Step for Technology Expected to Change the World

Australian researchers have developed and tested the world’s first quantum battery.

Their prototype is far from anything that will be a perspective power source in an EV or storage facility, but the experiment revealed some important directions for future research.

A theoretical concept since 2013, the prototype was charged wirelessly with a laser, one of the special properties that quantum mechanics in battery technology promises if it can be properly understood and harnessed.

Lead researcher Dr. James Quach of CSIRO, Australia’s national science agency which led the study on the device, said it’s the first quantum battery ever made that performs a full charge-discharge cycle.

Dr. Quach explained that in society today, the larger the battery, the longer the charge time.

“That’s why your mobile phone takes about 30 minutes to charge and your electric car takes overnight to charge,” he said, adding that in contrast, “quantum batteries have this really peculiar property where the larger they are, the less time they take to charge.”

Less time really is an almost worthless descriptor in this case, because the prototype created by CSIRO was fully charged within a few quadrillionths of a second.

The problem is that the discharge rate was a few nanoseconds, which despite being 6 orders of magnitude longer, could be of no use to anyone now. Quach provided some interesting relative comparisons to help mere mortals conceptualize why this could be a world-changing innovation if improved.

If it takes 30 minutes to fully charge a mobile phone, and it too had a discharge rate equal to 6 orders of magnitude, that means it wouldn’t need to be recharged even after a decade of use.

“What we need to do next is… to increase the storage time,” Quach said, touching on this point. “You want your battery to hold charge longer than a few nanoseconds if you want to be able to talk to someone on a mobile phone.”

Additionally, the prototype doesn’t hold enough voltage to power anything substantial.

While this might all sound rather pointless, another, non-involved expert in the development of quantum batteries, University of Queensland Professor Andrew White, told the Guardian that the experiment was a huge success in getting the technology off the drawing board and into the real world for the first time.People would be far more likely to adopt EVs if they could be fully-charged in few seconds, even if their range was severely reduced.

Endangered Cahow, One of the Rarest Seabirds in the World, Hatched on Nonsuch Island in Bermuda

Though an event neither singular nor inaugural, the hatching of an endangered seabird and national icon of Bermuda is still being celebrated wildly by a special group of conservationists who’ve created a “living museum” on Nonsuch Island.

Measuring just 14 acres and found in the northeast corner of the Bermuda island chain, Nonsuch Island is the only place the world’s 3rd-rarest seabird, known locally as the cahow, comes to breed.

The fact that it is breeding at all is nearly a miracle, as the cahow was believed to be extinct for a period of 300 years that started in the early days of British colonial governance and extended all the way to the second-half of the 20th century.


The animal, also known as a Bermuda, or gadfly petrel, bears all the quirks of an animal doomed to follow the dodo into history. It takes 3-6 years for adults to return to Nonsuch Island to breed, and if they do, the female may produce one egg.

That one egg may hatch, although it might not; some 50% of the eggs don’t hatch. Adults abandon that single chick one-week before it fledges, when instinct drives it to seek food out at sea while still learning how to fly. Between 28 and 35% of fledglings don’t survive their first year.


Nesting on the ground, they’re extremely vulnerable to predation from invasive animals, and in 1960, British ornithologist and Bermuda’s first conservation officer, David Wingate, identified just 18 breeding pairs on Nonsuch Island.

Wingate would go on to pioneer the Cahow Recovery Program, which today is recognized as one of the most successful restoration projects anywhere in the world for a Critically-Endangered species.

By the time Wingate’s successor as chief of the program, Jeremy Madeiros, took over, their numbers had grown to 55. Today, there are 450 birds of all ages on the island, a remarkable turnaround.

Part of that turnaround was making sure these birds had good nesting habitat. Cahows nest in underground burrows or deep rock crevices; only nests deep enough to be completely dark are chosen.

Today, 85% of all cahows nest in artificial concrete nest burrows constructed for them as part of the Recovery Program.

The recovery program gestated a transformation of Nonsuch Island into a complete wildlife sanctuary, wooded, and with a small freshwater marsh where access to the public is strictly limited to prevent invasive species introduction. The restoration of the once barren island into a ‘Living Museum of pre-colonial Bermuda’ was Wingate’s life’s work.

65 years into this rewilding experiment, key endemics have repopulated the island, including the yellow-crowned night heron, West Indian top shell, land hermit crabs, and the beautiful Bermuda skink.Expeditions there are organized by the environment ministry for educational and research purposes, while several live camera feeds allow those interested to observe the cahow in its natural habitat.
