I have thought for some time that it would be fun to build a robot
that crawled very very slowly across sand, digging it up, refining it,
extracting trace elements, and using the results to make PV cells
inefficiently and badly.

These it would leave connected up in a trail behind it as it moved
forward a few meters per day. The cells would provide all the power
it needed, of course.

But what on Earth could we do with all the spare power that would be
available after it had been left to wander about in a desert for a few
years? There must be some use for it...

Best wishes
