Well, there's so many different starting points for electricity and Benjamin Franklin with the kite in the rain and with naming positive and negative electricity was very important. But I would say that the start of generating electricity, which is so vital for us using electricity, starts with Faraday in 1831, because he figured out how to use magnets to make electricity.

Oh yes, definitely. So what he figured right after he published his work, so he figured out changing one magnet created electricity or induced electricity in another coil. And he also found moving a magnet induced electricity. And like months later, this guy in France who was working for Andre Marie Ampere, like amps, like current in the wall.

This guy named Hippolyte Pixie, he built this machine, and it was a bar magnet with two coils. And you spun the bar magnet, and as the bar magnet went towards the coil, it made electricity go one way. And as it went away from the coil, it made electricity go the other way. And that's called alternating current or AC electricity.

And we currently generate our electricity basically that same way, except we use electromagnets instead of permanent magnets. So like, let's see, coal power. You burn the coal, you make steam that spins turbines, which spins electromagnets near coils of wire. Or wind power, of course, or nuclear. There's a nuclear reaction, it makes steam, which spins electromagnets near coils of wire.

all of them except for solar, use this basic principle. You spin electromagnets near coils of wire and that induces the electricity.

There was a major learning curve. The problem was that they didn't have particularly good motors and they didn't have good light sources. So not only were the generators not very efficient, but also they didn't have good uses for them. And so Faraday made his discovery in 1831. Hippolyte Pixie made the first

generator where you spun something and the magnets move towards and away from the coils of wire. And it wasn't until the 1850s, that was 20 years later, 1860s, even 1870s, before they started to figure out how to use electromagnets instead of permanent magnets. And then at the same time in the 1860s and 70s, they started working on different kinds of light bulbs and light sources.

And so it took until the 1880s before people like Edison said, I think I have a good idea. We're gonna use this kind of generator and we're gonna have light bulbs that aren't very bright, but a whole bunch of them. That was actually Edison's discovery. It wasn't the light bulb.
