Summary
Good until the end, when it crapped out
The Good
Great teaching concept. Good examples and real-world tests
The Bad
The end game failed. The windmill generator is supposed to have a voltage of 22000 at 4000 windings.
In the copy I bought, the maximum voltage at the windmill was 12800. There was no way to get a total voltage of 40KV across the 3 generators. I wasted a couple of days trying to figure it out before I went to the walkthrough and found out how it was supposed to work.
The Bottom Line
How to hate physics in one medium-hard lesson
