Pat Riot Posted February 25, 2020 Share Posted February 25, 2020 That is a very good question. This doesn’t explain that but it’s interesting reading. http://members.kos.net/sdgagnon/te4.html Link to comment Share on other sites More sharing options...

Three Foot Johnson Posted February 25, 2020 Share Posted February 25, 2020 The same way they recharged Baghdad Batteries a couple thousand years ago I guess. Link to comment Share on other sites More sharing options...
Clay Mosby Posted February 25, 2020 Share Posted February 25, 2020 When we visited Bodie, CA the Park Ranger told us how when they got one of the first electricity systems in the area they ran the lines as straight as they could because there was some concerned about the electricity going around corners. And when they got to a building, they just popped a couple holes in the wall and ran the wires inside. Link to comment Share on other sites More sharing options...

That's why most electricians level up receptacles, switches, panel, etc.....otherwise the electricity all runs to one side. Link to comment Share on other sites More sharing options...

Um — run a cable to the top of the clock tower to catch a lightning bolt and generate the needed 1.21 gigawatts. Link to comment Share on other sites More sharing options...
Happy Jack, SASS #20451 Posted February 25, 2020 Share Posted February 25, 2020 The early batteries by Edison were nickel/iron. Used caustic not acid. Lasted almost indefinitely. Were often used in submarines except low voltage per cell and heavy. We gave up on lead acid off grid batteries a few yeas ago and now use nickel/iron. No acid corrosion and last almost forever. After about 20 years drain the caustic, replace and they are like new. Also in the early days on the great planes they used windmills like the ones used for pumping water with generator heads to produce electricity.

That's why on long runs I like my conduit to run slightly down hill. It helps the electricity flow a little better. Link to comment Share on other sites More sharing options...
Alpo Posted February 25, 2020 Author Share Posted February 25, 2020 That would make sense for direct current - it only goes one way so I can see helping it go downhill. But my house is alternating current. It goes out and comes back, right? That's why it's alternating? So if it flows downhill, it has to climb back uphill.

Ozark Huckleberry Posted February 25, 2020 Share Posted February 25, 2020 There’s another reason it’s called alternating current. It’s not PC to judge its life choices. Link to comment Share on other sites More sharing options...

It has to come back, either via a second wire or by an earth ground. Half the trip is still up hill. Duffield Link to comment Share on other sites More sharing options...

Duffield That's true, but by then the electricity has done its job and is lighter, therefore it's easier to push uphill! Link to comment Share on other sites More sharing options...
