Ask HN: What are some good resources to learn how electricity works?

I’m Joseph, and along with Arpan and Bailey we are the founders of OutSail Shipping ( https://ift.tt/8PBRduF ). We’re building a sail the size of a 747 that rolls up into a shipping container. When deployed, it will generate thrust from the wind to reduce the fuel consumption of a cargo ship. An array of these devices will reduce fuel consumption on ships by up to 20%. These sails are easily stowed and removed to cause no interference with cargo operations. Here’s a short video showing our prototype: https://www.youtube.com/watch?v=VUpVqzpym54 . Sails powered ships for millennia; but then the convenience of energy-dense fuels displaced sails. As ship speeds eventually exceeded wind speeds, the consensus became that sails had no place in shipping and were relegated to hobbyists and sport. Fast forward a century and a half, and maritime shipping, like a
