When this movie was made, suitable diodes didn't exist. The only suitable high current rectifier in those days was mechanical -- a commutator. Alternators replaced generators in motor vehicles in the very late 1960s and early 1970s.
@@lwilton Motorola developed the automotive alternator and Chrysler Corp. began using them in 1960. It took a decade for everyone else to adopt them. Fun fact: Some GM cars used the term "GEN" on the dashboard years AFTER alternators had been adopted!
@RinksRides Something like a relatively high-power rectifier like a 5U4 is many times the size of a buzzer, draws a continuous 15 watts in filament power, would last about a year before being needed to replace, and can handle half the current of a 1N4004 silicon diode. Just not practical in this application. A better choice would have been to use a capacitor. Those were commonly used to suppress arcing across point contacts and to control inductive kickback.
This is stuff I learned in the Navy as well as community college back in the ‘70s. I never used this knowledge much, but it’s been very good to have these basics in elec., electronics, and power generators. I’m surprised that I remember as much as I do (which isn’t a lot).

This film "generated" a great deal of interest in electric generation
Back in my day, we didn’t refer to electrical discharge between different pieces of equipment as “sparking”. We called it an “arc” or “arcing”.
Ok, thanks.
Diode bridges for DC, as in vehicles to charge the battery and car DC power supply.

Excellent presentation.

If this takes someone a year to learn they may be in the wrong profession
What year??
👍👍
I know (almost) all about motors and generators, brushed or brushless induction.
You don't know shit.
hold on chief I am just putting your medal in the post.
LMFAO 😂
Note to millennials and zoomers - these kinds of motors are still being used today.
i came of age in 1998, hence I am a millenial, and I am an electrical engineer. what is your point?
@@KarldorisLambley The point is to indulge in some inter-generational humor.
@@CorvinusIratus oh dear. i see now. i am not very god at that sort of thing. i am sorry. thanks for being polite.

This all is wrong. It's all about pushing little balls through a tube.
You are 💯 correct!
Yes, yes it is.
