I hope one day we will be able to charge devices without plugging them in - even if the amount of charge is small, it might be able to trickle charge all the time.

Waiting for that Thunderf00t video on this.

Singaporean: Take my money!

Sorry to hear the scientist commited sudoku tomorrow with 2 gunshots to the back of his head. /s

I imagine this having practical usage in maybe keeping things like sensors working in a plumbing or caving kinda context considering the low power currently created. Awesome!

According to the Lyubchyks, one of these devices can generate a relatively modest 1.5 volts and 10 milliamps. However, 20,000 of them stacked into a washing machine-sized cube, they say, could generate 10 kilowatt hours of energy a day – roughly the consumption of an average UK household. Even more impressive: they plan to have a prototype ready for demonstration in 2024.

That’d be cool if it worked, even if it does it will be cost prohibitive for quite some time.

Feel like there is still room for error, so this needs to be investigated further. Would be a great substitution.

It sounds interesting, but I don’t quite get where the energy comes from - it sounds like they are harvesting the kinetic energy from the water molecules? So what is the net effect when scaled up? Does the device get very cold? an ELI5 would be appreciated

So if this gets scaled up for global use won’t it cause issues by drying out the air?
