[sdiy] DIY IC's at Home

[Ian Fritz]

Well, read the transcript and see what it actually says.  First, you have 
to put down a plastic film with electrodes. So we're back to that 
already.  Hardly a paint job.  Then, this TiO2 layer you are going to paint 
on couldn't possibly work unless it is just a few microns thick and 
uniform.  Not much room for error here.  Then some mythical conducting, 
transparent clearcoat for the top electrode.  Something totally 
weatherproof, to boot.

And as it is, the world only has about five years worth of Indium reserves, 
which is going to make any massive solar photovoltaic rollout virtually 
impossible.  I know some of those multijunction solar cell folks -- they 
never talk about where all the exotic material is going to come 
from.  They're just playing in their labs.  Great fun!
