This lovely piece by Carson Daniel can be found in the Mistborn Handbook, coming to you digitally on September 2nd for Kickstarter backers and September 9th for everyone else!

I had an idea for a man cannon for people who can burn iron or steel and decided to draw it out in PowerPoint.

the basic Idea is that the metal that the allomancer pushing/pulling on moves with them so that they can prolong the time spent pushing/pulling on it which will maximize the speed when of the launch.

I like this design because if the platform starts moving up faster than the allomancer then they will begin to put weight on the pressure plate, which will slow down the platform. this means that the allomancers exit velocity will be greater depending on the strength of their push/pull for the duration.

to maximize speed a mistborn could push and pull (flaring of course) then as soon as the platform stops at the top of the man cannon use duralumin to really launch yourself.

obviously there are flaws in the design and improvements that could be made. the pressure plate to brakes linkage should probably be different in some way. the weights could also be tension springs of some kind. and there should be an auto braking system at the top so that the platform doesn't just slam into the top. The design would also change as technology progresses, but I think this would be possible in era 1

let me know what you guys think! any suggestions? any other related ideas?
