Also, using a handheld mixer (with a crank for human power) to create a vortex in the water would increase the effective surface area and significantly speed up the heat transfer from metal to water, and even out water temperature. It would reduce boiling time by a decent amount if the heat output from the coal is high.
Instead of using a bicycle tire pump, how effective would it be to mount a fan on a gear powered by the petaling from a bicycle, with a cone (big end on the fan, thin end toward the coal) for increasing air preassure?
With >250W of human labor from petaling to drive the fan, i would guess a 25-30cm diameter fan could do a good job? It would give good sustained air flow.

@gulllars Great ideas! If you test them out and post a video response, I'll link to it at the end of the video.
