Thier big on solar power to charge the batteries for thier tail lights on thier buggies. They have small solar cells somewhere on thier house or out buildings that they use. Theres a building north of here the Amish own and manufacture wood crafts and buggy wheels. The whole building is powered by one diesel engine that runs all the machines via the old fashioned flat belts and pullys. I’ve never been in the building but would like to take a tour to see that old machinery and technology work, how longs it been since anyone has seen babbit bearings.
