Torque measurement?

I don’t think anyone has done any proper studying on the subject, but what has been done is probably here:

Power Meters and Unicycling

I’m wondering if anyone has installed a power meter on their unicycle yet? The data would be even more interesting on a unicycle than a bike, because we use variable crank lengths, and only one or two fixed gears. You’d be able to calculate optimum crank length and cadence based on power output for a particular rider, rather than speed (which would be affected by wind resistance). There are also ways of calculating the drag co-efficient based on power measurements, which would be cheaper and …
