Space Trains
If we’re going to go the Planets! route we need better ways to get into space.
Actually we need better ways to get into space, period.
Modern rockets aren’t all that bad in terms of cost (making more than one at a time helps a lot), but they’re like aircraft of space. Important blues and their support teams use aircraft. Average oranges or purples or whatever don’t, they take the train. Same thing with rockets. They’re all operated the government or big-budget corporations.
I want a space train. Something anyone can buy a ticket for and get on and ride with no fuss and no special arrangements. I want everyone to be able to take vacation trips on the LAO (Low Amentan Orbit) express to orbit and back, to be able to travel to space for business and open a cafe at L1.
And the only way to get a space equivalent to our (really quite excellent) train systems is with some kind of giant infrastructure project. No way around it. There’s a few options rolling around. Space elevators are the most popular one - too bad they’re actually pretty much impossible unless material science greens manage a few dozen miracles.
My personal favorite is the launch loop. I don’t actually have the engineering chops to even begin to design one but I’ve read the designs of someone who did and at least I can give the concept some exposure.
The key concept is that the launch loop is an ‘actively supported rail’. You know how you can float a piece of paper over an air vent? If you have really good aim, you can scale that up to a garden hose holding up a metal pan. If you have a lot of dedicated yellows and greens and purples and blues and a huge budget, you can scale that up to a stream of semi-solid iron being propelled up a giant looping tube thousands of kilometers long by giant power plants at either end, all supporting a magnetic-levitation train track at the top edge of the atmosphere.
Trains can just accelerate along the track constantly until they’re at orbital speeds. Carriages can go up the loop every few minutes like clockwork. No need for special clearance and checking flight lanes. No need for huge, expensive rocket engines bigger than my parents’ house, or fuel tanks bigger than banks’ headquarters.

Here’s a video that explains the concept pretty well: https://www.youtube.com/watch?v=J1MAg0UAAHg
Here’s a legitimate technical document proposing a well-researched actual plan to build such a thing: http://slides.launchloop.com//launchloop.pdf
(Space trains are a terrible terrible way too expensive idea if there’s not enough demand to get into space. Like building a massive four-platform high speed rail station in a podunk farming village with just 20 purples and one lonely orange or something. But we have moon bases already, I think there could be a market for it if space travel was suddenly much cheaper.)

this is the most awesome thing i have read in like a while
i am way too purple to get this shit but
fuckin space trains
SPACE TRAINS!!!
This added a wonderful break from the whole 'constant sobbing' hobby I've taken up. It's nice to have something hopeful in my day- thank you.
