quite interesting video. Remember the blackout of 2003?
That was so hardcore. Nowadays most of the facilities are upgraded and if i remembered correctly, a more advanced and state-of-the-art system was completed a year later back in 2004....couldn't remember that much, but despite that, i love this video.
That's true. Only the older ac motor driven clocks relyed on the powerline frequency, but there are probably millions of them still out there on the walls.

I see. Thanks for uploading these videos. I remember your other series on TVO... you taught me how a CRT works amongst other neat stuff.

Where I live the electricity supply won't keep your clock on time. It won't even keep your computer running long enough to

Great stuff. I understand that electric clocks no longer rely on the mains frequency to keep good time.
