(newton and the cannonball), YES, it is, I think that this idea is the source of the idea that : the moon is exactly doing that: falling into the earth but the speed and the radius of curvature is = to the diameter of the orbit. Then ... DING! universal gravitation came out. Best regards, Simon Plouffe 2014-09-30 15:48 GMT+02:00 Henry Baker <hbaker1@pipeline.com>:
Didn't Newton's original diagram for putting cannonballs into orbit show a cannon being fired from a mountain top?

this corresponds to 31% increase in payload (for 5 km launch altitude) to 122% additional payload (for 25 km launch altitude).
Cool, but you have to amortize that over the construction cost and lifetime of the tower. I bet you need to have an awfully large requirement to orbit mass to pay for it.
