Would be interesting if they standardized twist-lock plugs. But I have to wonder. Was the current outlet designed so that one could remove a plug-in right away or something?
I often wonder with electronics and everything consuming smaller and smaller amounts of electricity, if we'll see a lower voltage standard? I mean all your shit has a step down transformer. That's all wasted heat. One day, maybe 500+ years from now, electronics will consume what little energy density is in a simple RF wave. Like a cell signal.
A lot of devices have switch-mode power supplies which are generally more efficient.
And a lower voltage standard will require higher current draw, which will require bigger conductors, so invest now in copper futures.
You also experience more power loss when current draw is increased across a conductor, so the attempt to save some power with a lower voltage might actually increase power waste. There's a reason that power companies distribute electricity across long distances at five-digit voltages.
More volts means less amps which means lower losses and the ability to use smaller conductors.
500+ years from now, I'd hope that room-temperature superconductors are common, quantum computers are everywhere, and battery tech has developed a little bit beyond the best li-ion cells we can make today.
And yet we'll still have tricorders that only last 6-8 hours per charge. Sure, they'll operate on 10-megawatt-hour batteries, and perform 20,000 quadrillion operations per second, but it'll
still be designed so that you'll always want to carry around an Energizer power pack, which will be a handheld fusion generator able to provide up to 10 tricorder charges per refueling.
