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

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.
