But do they have any other valuable resources? Metals that can withstand the impact of micro-meteoroids over and over and over as it travels for hundreds of years through space? You need a hell of a lot of resources... you can't build a ship out of pure fuel... OR CAN YOU?! :O

Asteroids, as a whole, basically have all the same elements as Earth's crust. Did you really not know this?

Once you get the metals/Oxygen out of the asteroids, how do we turn that into usable ship parts? Would we have a refinery floating in space, or do we have to bring it back down to earth? (In either case, where do we get the fuel to either 1) get the refinery INTO space, or 2) get the elements down to earth and back up to space?)

I'm confused by the logistics (or lack thereof) proposed for this project... Even if they have the base for fuels and metals... what do you do with the raw materials?

None of these projects sound feasible in ANY way; we need the initial resources to BUILD all of these "things" which only serve to go out and find more materials... but then we have to have a way to build the ship parts out of that, we need energy sources for all of these "things", which require more resources... It just seems a bit larger in scale than we can handle at any point even remotely within the next couple centuries (physics permitting) to build a generation ship.
