For Void re horizontal Spinlaunch: https://newmars.com/forums/viewtopic.ph … 17#p240617
Thank you for a truly astonishing invention.
The original SpinLaunch concept employed a vacuum chamber to avoid losses to the air during acceleration, and it had a vertical orientation to reduce the amount of air to be traversed on the way to orbit.
Your creativity has broken through the mental barriers that inhibit most other humans.
The horizontal version of SpinLaunch would indeed work well on the Moon or any other airless body.
It is entirely possible that Calliban may have suggested something like this, and there may be posts right here in the forum where a version of that idea is on offer, but your version of the idea is particularly timely.
I wonder how it would compare in difficulty to the traditional O'Neill type mass accelerator, or to simple chemical rockets, or to any of the other creative ideas humans have written down since the start of the Space Age.
I will add your vision to the appropriate topic as soon as I can figure out where it would best fit.
Good Coffee!

For Void re slide concept for lunar launch: https://newmars.com/forums/viewtopic.ph … 31#p240631
Your picture of a slide that can be adjusted to various angles reminds me of a "rail gun".
A "rail gun" is a kind of slide. It is a remarkably simple device. If you ask CoPilot, it might be able to provide an interesting analysis.
The US Navy is one of several organizations that have experimented with rail guns.
The operating principle is magnetic force. If you ask CoPilot, it might be able to create an image showing how magnetic forces interact to move a cart along the rails.
If you ask CoPilot, it might be able to provide mathematics to show how such a device would work.
If you decide to venture in that direction, you will have to provide CoPilot with starting numbers.
I would offer one metric ton as the mass to be accelerated, and the escape velocity from the Moon as the desired velocity.
With those two numbers, CoPilot should be able to tell you how much electric current you need to provide to achieve the desired launch.
A rail gun depends upon capacitors to deliver power in the short time frame of a launch. CoPilot might even be able to calculate the size of the capacitors needed.
