Huge huge miscalculation on his part here.

Electric motors all have efficiency curves which show the efficiency (power output to power input) relative to the RPMs of the motor. Without addressing that, the rest of this experiment is meaningless. If he tested it on ten different motors he'd come up with ten completely different results.

What he SHOULD have done was to use a motor that he can fix the RPMs, adjust it to the peak efficiency RPMs for each setup and then measure windflow and power consumption. That would give him some numbers he can use.
