I have possibly a blasphemous idea, hear me out.

I was chilling at work, when a great idea hit me. I need to do an engineering project for my college course, so I got to thinking.

A trebuchet, where there is no counterweight, but an electromagnetic system, where in the electromagnet turns on, pulling the arm down and making it work. This would allow for easy transport as less weight and a variable range. Possibly exceeding 300m.

It may be stupid, but I belive we can revolutionize the way we see the trebuchet.
