An idea I had a week or two ago, a launch vehicle exclusively for delivering liquid hydrogen propellant to orbit, to supply a fusion spacecraft or similar. This concept uses hydrolox propulsion with a common bulkhead between the LOX and LH2 tanks; the payload is contained in the same tank as the fuel.
Not sure why it is called "orbital", as it isn't an orbit-only vehicle, it doesn't go from orbit to orbit or anything like that; effectively it's just a species of launch vehicle. But it does launch to orbit, I guess.
The sunshade isn't shown or described in the document, but I've envisioned it as basically a sheet of solar sail material (not for any propulsive purpose, it's just lightweight and reflective) extended on spring-loaded booms, somewhat similar to long, thin antennas. I know this arrangement doesn't provide 100% effective shielding, but for what it's worth, it provides at least some shielding.
Don't take all of the numbers too seriously, a lot of the smaller mass breakdown figures are more or less thumbsucks by me, and the cost per kg is at best very rudimentary. Nevertheless, if you spot something that's blatantly, obviously, horribly incorrect, please tell me.
Overall I generally need a cheaper cost/kg figure, which would probably require a less... mundane system, but for what it's worth I think it is rather nice. I'm sure it has a use somewhere in the Orbitersphere.
The only real downside, is that it ended up looking like a feminine hygiene product. :facepalm:
