The people making the Vasimr engine ripped off my idea. What? How? When I was a kid, I had the idea of getting to Mars in just 40 days. The Vasimr engine uses radio waves to ionize and heat propellant to do just that. That's pretty impressive. How'd you know that radio waves could ionize and heat propellant when you were just a kid? Not that part. Just the "40 days" part. Less impressive.
