  • If I’m coming back before the iron age, electricity isn’t my biggest concern. All you need for a magnet is two pieces of iron to rub together, and copper is one of the easiest to work metals on Earth. Indigenous people here in Michigan were mining and working copper over 6000 years ago. Your dynamo doesn’t need to be good, it just has to prove the concept.





  • A copper coil, a magnet, and a repetitive source of motion is not that hard. You’d have to go really far back not to have access to a mill, and even if you did, it wouldn’t be that hard to invent a hand crank. The question is how you make the electricity useful. I think a simple heating element is probably the best option. Show them the river cooking their food, and the benefits should be obvious
