Those are some good ideas, although I am somewhat skeptical when it comes to terraforming large worlds (not that I think its beyond our ability, but rather that many humans have short attention spans and may lose interest if it took longer than a century).

But even if we left Titan as it is, it would still be a vary interesting world just from the science alone on that frigid moon.

One advantage for human powered flight is the low gravity – 14% of Earth’s. And if there was ever a world where pushing an airship into orbit was possible (ala JP Aerospace’s plan) it would be Titan, with an orbital velocity of just 1,600 m/s.

But what about terraforming? Obviously Titan is too cold for human comfort currently and probably too icy to want to increase to room temperature. But what if we raised the average temperature to 233 K? That’s cold, but manageable – there’s a few Russian towns that endure such environs. With fusion-powered heating systems it’d be no problem at all.

There’s definitely carbon dioxide on Titan so we’d have something to convert into oxygen other than ice, and with the right mix of fluorocarbons we might be able to warm Titan enough by increasing its effective insolation to just 10% Earth-normal. That would need a soletta collecting an area of sunlight 10 times bigger than Titan, thus it would be about sqrt[11] times as wide – assuming it’s directly behind Titan relative to the Sun. Big, but not ridiculous. Some energy could be diverted into a beam to pyrolyse carbon dioxide or water to make oxygen. So what do you reckon?
