So we got that figured out. Yes, no problem. Manuals. Make sure you've got your electronic manual of your radio downloaded someplace that comes in very handy. OK, but I was also reading a three-game article about electric vehicles, where there's quite a switch, beginning to be quite a switch over from copper to aluminum for conductors. Aluminum, of course, is much lighter than copper, significantly lighter. It's also much less expensive. A ton of copper right now is just under $15,000 a ton, a metric ton. And aluminum is about $3,000. So there's been a four-to-one on the fight-one ratio there. What you need to remember about copper, though, versus aluminum, is aluminum is not as flexible. So it is lighter weight. It is less expensive. But for a given amperage, you have to have a large cage wire, for example. And it's also not.
