Re: Yeah, bad weather is a problem
the biggest-ever historical trebuchet
It would be interesting to see what a trebuchet designed by engineers with modern materials and techniques could do. I know someone has build a supersonic trebuchet. There's also an old Harry Harrison SF novel with, inter alia, a steam powered trebuchet(*).
(*) I have absolutely no idea whether such a thing is feasible. Is there a hardware engineer in the house?
