Ok, a few people have been saying this, I'm gonna join in.. how does this help anything? The problem being that it takes a lot of energy to get the fuel into space to propel spacecraft to where ever they are going.. ok, understood, so having the fuel already in space means it takes less energy to get a lighter spacecraft there, and then it can fill up and go wherever. Good.
Except... how do we get the fuel up there? by sending it on a spacecraft? in which case, we would also have to deal with transporting the mass of the tanks themselves up there, and then duplicate the energy we would've spent on sending a heavy spacecraft in the first place?
Its like saying 'I can get better fuel economy if I only half fill my car, and top up the tanks midway there', but then driving a tanker halfway along your journey so you can fill up from it. seems completely retarded to me.
Its easier and cheaper to send up 4-5 smaller rockets (can use current rockets such as ariane 5) with fuel up to a station than send and develop a huge ass rocket (which will have to pretty big to contain fuel from ground to orbit then to mars and back which adds weight which requires bigger rockets which need to be developed =more expensive) to get to mars where more things can go wrong, a lot easier to develop a smaller craft to get from earths orbit to mars or further. Also opens up the opportunity to build craft in space

Tim, you do this every time you stop at a gas station. Your saying it makes as much sense for a cross country trip to haul all the fuel you'll need with you so you don't have to stop. Now that's retarded :)
The X-Fi3 keeps with the company's commitment to audio fidelity, thanks to the apt-X codec, which supposedly offers audio quality similar to a wired connection when streaming. On that front, the device also handles FLAC files.
