ok... even if you build it 5km in the sky, a 1km long launch rail would still apply 6,000 Gs of acceleration. Good luck designing a spacecraft that can survive that.
- sliken 9y agoOr don't waste 5km and make the tube 5km. The acceleration drops to 1282G. Digging a 1km hole drops it to 1000G or so. Not really that much. About the acceleration a woodpecker head gets, less than a baseball being hit by a bat, or what a wrist watch can withstand. Under 1/10th that of the electronics in an artillery shell.
