What was the direct mechanical result of Halladay using many thin, curved blades (16 to 32+) compared to older designs?

Answer

It significantly increased the surface area catching the wind

Halladay’s design featured a large number of thin, curved blades arranged in a circular pattern, which significantly increased the total surface area capturing the wind, thereby generating the necessary starting torque for pumping.
