Oddly Fascinating

|
I find it oddly fascinating that in the split phase electricity system used in the United States, the only power that flows on the neutral wire back to the center tap of the pole transformer is the difference in amperage between the phases.
So if you have …
20 amp draw on the Phase A
30 amp draw on Phase B
You’ll have 10 amp flowing on the neutral, which is also referenced to the ground
If you disconnect the neutral from the center tap of the transformer, the 20 amp load will work okay but the 30 amp circuit will see its voltage cut by 1/3rd.

Uranium Mine

"Rock layers are visible at an inactive uranium mine on Kazakhstan’s Mangyshlak Peninsula. While this particular mine closed in the 1990s, Kazakhstan continues to be an important source of uranium and in 2019 produced 43% of the world’s supply. Uranium is primarily used for nuclear power generation and is also used in the creation of nuclear weapons." https://www.over-view.com/overviews/kazakhstan-uranium-mine

America’s Three Power Grids

|
America has three electrical grids that are not synchronized to each other, and can not move alternating current electricity between one and another.
 
Generally speaking, a power plant in Oklahoma can't send electricity to most of Texas or Colorado.
 
Each grid was built separately and are incompatible with each other, although a limited amount of electricity can be moved between the interconnections using AC to DC to AC conversion. But such conversion is complicated and expensive, and isn't as simple as stringing lines between the grids.
