If we want to accelerated from 0 to 120 rpm in 10 seconds, the difference in power required to accelerate the two wheels from 0 to 120 rpm is approximately 1.02 Watts.

For the wheel with a change of 453g:ΔK = 48.8 Joules (calculated earlier) t = 10 seconds

P = ΔK / t = 48.8 J / 10 s = 4.88 Watts

For the wheel with a change of 906g:

ΔK = 59.0 Joules (calculated earlier) t = 10 seconds

P = ΔK / t = 59.0 J / 10 s = 5.90 Watts


And what do you mean "a valiant effort"? He was a friggin' genius, especially considering it was the 17th century. He might have even been smarter than the guy from Cambridge with the YouTube video.
