Great oldie of my time.

It's a very cute, very on-point way of introducing the concept of electricity - they hit all the high points: where it occurs in nature, how it's generated and transmitted, a little bit of Ohm's Law, a safety message, they even throw in the Superman Paradox.

(That's the bit that says, by logical progression, Superman would save the maximum number of lives by simply turning a generator 24/7 and acting as a source of cheap, unlimited power).

The one slightly inaccurate bit is that not all power is generated by fire heating water. Hydroelectrics generate it by flowing water over turbines, and of course, windmills have been simple power generators for a *LONG* time in the rural parts of the world. (Yes, they were directly used as a source of electricity as well as mechanical energy, before things like FDR's Rural Electrification program got power to every corner of the country).

Whew! Yeah, I'm severely educated.

Yeah, I woulda thrown in a little bit about hydro and wind power, myself.
