Quantum Entangled Batteries Could Be the Perfect Power Source

They are full of....., many magnitudes of misreadings, to start with. Entanglement is the property of a single particle split or some such, not a macroscopic battery.

Confusion, big time.

OK, several thoughts come to mind in stream of consciousness (its much too early here): 1) once upon a time "futurists" thought that atomic power plants would be common enough to run aircraft, 2) once upon a time, the thought of sending information faster than an auctioneer could speak, let alone in megabytes per second was fantasy, 3) while quantum entanglement talks about the linking of states over distance (and time, apparently), we only are beginning to understand the framework for creating the effects, let alone concentrating such entanglements in a confined volume enough to create a practical battery. But... IF they manage the density AND the physical environment needed (cryogenic liquids needed?) AND if they can figure a practical charging station, THEN given the energy transfer would happen at a distance, you get the possibility of a municipal central power plant (or home plant) powering every equipped demand source (electric vehicles needing only a quantum battery could result in all the benefits of electric motor vehicles with the equivalent of "wireless power transmission"). Then under those conditions, I would not call it a battery, I would call it a receiver.

Again, when a basic researcher talks about "in the future," the technology could be only a couple decades away or never happen.
