How Electricity Actually Works

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.

Thanks for injecting some sanity into this thread.

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!

There are some interesting and amusing arguments regarding E and B fields and their uses in this thread. Some of what I read here makes me seriously wonder about our education system.

That is a bit of a drive-by @audio-union. Can you comment on what specific items are at issue and if they have been suitably addressed?

    You mentioned not knowing a tenth of a percent.

     The percentage of what we know about our universe, is recognized by Scientists/Physicists as 4-5%.

In order to put a percentage on what we don't know, you would have to know accurately what there is to know which is impossible if you only know 1/10% of 4-5%.  I am always amazed by just how much we collectively do know.
