There ain't no free lunches.  Puting large enough solar arrays in deserts
results in two effects:  some energy is carried away on wires, and a lot
more is reflected back out by the panels than was reflectd out by the
desert.

The result - after only a year or two - is vegetation.

What worries me a bit is the inclusion of the models.  Methane release
wasn't included in early warming models, for instance.
