Most accurate formula to calculate energy from gravity

Fri, Apr 15, 2005 at 12:02 AM

Hi everyone in energyfromair.com,
Through some knowledge of differentiation and integration, I have
derive the following formula to calculate the gravitational energy
extracted from one single rotation of a non-cylindrical mass.
For a hollow circle with R as the outside radius and r as the inner
radius,    E=40/3*(R^3-r^3)/(R^2-r^2)
This formula will be more accurate than E=2MGR.
