Interesting but not much information. Kind of hard to envision submicron positioning accuracy in a vehicle rolling accross rough grade. This one is more interesting

Just noticed the stuff you had at the bottom. Will have to look at that later.

I've heard of cells made from titanium dioxide, which is pretty much
what Ilmentite is made from once you get the iron impurities out.
They're cheap, easy to make but currently unstable. Here are a few
references:

http://www.ecn.nl/press/organic.html (Ditto, but abstract in HTML)

Do not be confused by people like Solarex who use a titanium dioxide
non-reflective coating on silicon panels.
=================
Another approach:- manufacture the heaviest components of solar dynamic
generators using metals extracted from lunar materials. The lighter
high-tech parts can be imported from Earth.
