Every few months, a physics lab does something genuinely impressive that forces me to want to write about it.

This is one of those moments.

Today, it’s a battery that can charge instantly, coming out of Australia.

Long time subscribers will remember the last time I wrote about those blokes down unda’ and their breakthrough quantum gravimeter that allows ships at sea to navigate with no GPS at all!

Must be something in the water down there… Or it’s the Tim Tam cookies, which, by the way, my Australian YouTube viewers got me hooked on and now I can’t stop eating:

My Costco actually had these in stock

Okay, so what’s this about a battery?

Australian scientists have made a big step forward in energy storage technology with the world’s first proof-of-concept quantum battery.

Quantum batteries. Quantum gravimeters. Quantum computers… It’s almost like throwing the word “quantum” in front of a noun makes it instantly worth talking about.

The research was led by CSIRO, Australia’s national science agency, with collaborators RMIT University and the University of Melbourne, and published in Light: Science & Applications.

The prototype is actually the team’s second device and the first in the world to successfully complete a full charge, store, and discharge cycle.
