$this->bbcode_second_pass_quote('Judgie', 'T')ransmission distance and land area needed for 500GW is the problem. Then again, if you are willing to accept a worldwide population below current levels (say 1 - 1.5 billion, with population control measures in place) then we may not even require that. IF we make it through peak oil, it is possible. Just be prepared to set population growth aside.
Personally, i'd like to see the flexible solar panels that are currently in development taken one step further, and turned into a fibre suitable for sails, tarpualins and tents. Regarding sails, it should preferably have near or the same characteristics as the kevlar-aramid sails that have been around for nearly a decade now. Of course, if it could be integrated with Dacron, that would be just as good.
Regarding the molecular printer, you can procure one of the early ancestors of these, if you have a spare US $50,000 to set aside.

http://www.zcorp.com/I have a nagging suspiscion though, that we would see the introduction of a "content" for want of a better word, licensing system, like your Microsoft Vista licence, whereby you do not actually own the window, you merely have a licence to print the window for so many window frames, or for your home only, etc. Furthermore, it could be revoked at any time and the windows removed. Window piracy anyone?, for those who do not wish to pay full price?. Actually, I think corporate window design and licensing could be a very lucrative business sector, especially if architecture continues as is, with glass facade's as it's darling. Anyone care to join me?

I have a friend that is working on a similar technology to the zcorp CAD printer only for a major player in the printing industry and printing, well, 'other' things that one wouldn't normally imagine as something you print. Can't really elaborate because of NDA, but it's pretty astonishing what's possible already. Given another couple of decades it would really be revolutionary stuff.
Even given all the hassles of licensing, which we know from software and music/movie downloads are a read nightmare, this technology just has so many advantages over traditional manufacturing. Just think of all the different stages involved in producing a sheet of glass today, from mining and refining raw materials, processing refined products into the end products, all the transportation at different stages - all that is eliminated by simply doing the whole lot locally. It's the ultimate in conservation, and if you could do it for all material goods, you would revolutionise the world by achieving the utmost in sustainability. Economic growth would no longer be based on what we can take from the Earth and dump back into it. Economic growth would be based on virtual growth, since the manufacture of all goods would be an information technology. Compared to today, you would basically have the capability for true unlimited economic growth. Assuming the population could stabilize of course.
To me, such a system sounds far more attractive than the current system, even if this system would enforce strict and dodgy "fair use" licensing systems. I'd rather have to pay for the right to print each glass window I wanted and consume in a totally sustainable way, than actually own the window that the natural environment paid for. Especially when you go from printing glass windows, to complex machines like cars and computers (or even food for that matter).
And regarding transmission distance - that would not be a problem with such technology because every system would be localised. Most energy consumed in a household would also be generated in that household, and likewise for every other sector. With the increase in cost performance of energy generation and storage, comes an increase in decentralized power generation. If such technology comes to be, I don't see why there would be much need for power transmission (apart from perhaps short distances, which could be done wirelessly by then).
