Hi there,

I'm based in Christchurch and want to get my hands on a Reprap printer.

Are you the guys for that?

Hi Vik,

The November 2009 blog post

is very interesting because I am interested in organic batteries and one researcher in Sweden uses Cladophora cellulose with a very dense surface area.
If the direct PLA one-step approach could be performed by inserting the gene that produces that fiber into bacteria, it could be used as a gel to print batteries.

The conductor in the battery used and other organic batteries is polypyrrole (PPy). This too, could be extracted from the biosynthesis of melanin, as it is a mixed copolymer of the most common melanin. If these pathways using bacteria (cheaper?) or yeast could be GPL'd, the RepRap would be able to print organic batteries extremely cheaply and perhaps stack low-capacity thin batteries and use them for residential backups(I'm hoping for 20kwh batteries, but that may be a bit too far). Nonetheless, I look forward to your thoughts.
