Ah, I see, I'm not so sure there is a lot of loss in the friction but
every little saving counts! Instead of the friction perhaps a direct
gearing drive would improve the efficiency you say? Hmmm, that would
involve placing the dyno closer to the hub and adding a gear to the
wheel with a smaller gear on the dyno to preserve the original ratio.
This might be possible... but certainly a propellor would not work.

It wouldn't be very surprising that they are very expensive.
