hello all.
i thought I'd share this with you all.
I've just been listening to a very interesting segment regarding the development of conductive plastics, which can, for example be used to manufacture plastic LED's, diodes, and circuits.
clearly, this is still a way off yet for RepRap, but it does exist on all our horizons.
podcast is here: (on my itunes, hope it works for you)

interestingly, this technology could also produce cheap photovoltaic cells.
Imagine.
regards and thanks to all putting effort into the project.
