How Electricity Actually Works

In November of last year I posted a Vertasium YT vid titled "The Big Misconception About Electricity".  Well it caused quite a stir and like an arachnid had many legs many of which attempted to draw A'gonrs into the poison fangs!

Well, here is the follow-up to that original vid which caused quite a stir in the "intellectual" community as well.

Vertasium "How Electricity Actually Works".

 

This does have implications for our audio cabling...

I think and i guess i hope that we are heading back to DC current.  Solar panels and Wind Power generate DC, Batteries store in DC, LED run on DC, really efficient motors use inverters to produce clean 3 phase A/C, but could skip the loss of the inverter and run on local 3 Phase DC.  There are limitations and problems and maybe safety concerns.  It would add huge efficiency if we could skip all the inverters, skip the inefficient grid and power plant.  some day.

The wind does not spin the propeller, it moves the car whose wheels are connected to the propeller causing it to spin.

I think that’s the key concept that allows the effect to happen. It still remains difficult for me to fully visualize. It's like a very good magic trick. It won’t work if you aren’t connected to the ground. Too bad, because then airplanes with no power plant could just magically make headway into the wind!
