/diy/ - Do It Yourself

Would this work in real life?

Teacher asked us in a test to step down 35V to 5V without using IC linear regulators, voltage divider wouldn't do the trick since it had to be a regulated output, and this was the best I could come up with, I've never thought of an opamp like this, it was simulated OK but realistically though, could this much heat and general inefficiency destroy an opamp?
