There are massive global multinational companies that have been working on engineering a better transformer for over a hundred years. ABB/GE, Siemens, Schneider Electric, Eaton.. you really think Elon has a fresh take on something that thousands of engineers have been working on for hundreds of thousands of man years? I realize that SpaceX solved problems that massive companies had been working on for a long time, but electrical transformers are dead ass simple. It’s a bunch of iron/steel and copper/aluminum submersed in oil. The principles of electromagnetism and induction are extremely well understood and have been for a couple hundred years.
