the orbital solar condenser + ground based collection disk from simcity 3000. like normal solar power but spicier
There is no problem that cannot be simultaneously solved and made cooler by the unmatched power of the sun.
I'm definately in the Orbital Solar Power camp of madcap dictator projects
Besides telecom and pure exploration, this is the only reason to actually go to space at all.
Offworlding all industry?
I have serious doubts we'll ever come close to a space elevator.(or launch loop or rotovator or unobtainium of the week) Which tends to raise a lots of questions as to how exactly we'll ship ballistic toasters.
Power is easy. Masers and rectenna arrays have decently good conversion rates and are light, cheap, and dont require slowing down 11km/s loads of space kipple.
We've been deorbiting humans for half a century, it's presumably easier for toasters.
The real challenge is speeding things up to escape the gravity, not nearly as easy compared to slowing them down. You'd need to launch an astonishing amount lot of equipment to offworld power production, which is why you'd develop a space industry in the first place.
Agreed, you'd need an astonishing amount of equipment to do anything up there. Which is why i can't imagine a logistics system on both sides of the gravity well for finished goods ever making sense. Heat shields & parachutes only get you so far when you start scaling up from a several people in a hollow capsule to bulk freight loads. Retrobraking adds a gas tax that scales with the rocket equation.
Any tech you have for making a self-contained, pollution-sequestering factory in orbit could probably be built on the ground a whole lot easier and cheaper. Which is why i dont think we'll end up having orbital factories without a scifi-ass megastructures or nuclear rocket engines & the headaches they bring.
But we'll probably keep slinging shit into orbit for a long time. Panels are cheap & getting lighter. Mirrors are cheaper & lighter still, and can multiply the effect of panels you have. And its all scaleable and implementable with current tech. Yeah, you're never going to off-world all power production with beamed solar this way, but it's a workable vanity project.
