<The main trouble with anything solar is that even at noon solar radiation is only around 250 W per square foot. And on the vast scale that we (and Brazil too) gobbles up the energy this is just so insignificant. >

10 feet by 10 feet would be 25 kilowatts. Converting only 10% of that would be a useful amount of energy at 2.5 kw.

A desert 100km x 100km would be 10,000 km2 = 10,000,000,000 m2.

10bn x 2.5kw = 20bn kilowatts, [or 20 million megawatts].

At 5c per kilowatt hour that's a street price of $1 bn per hour.

That's serious money. Australia and parts of the USA, not to mention the Sahara and lots of other places, have a LOT of desert doing nothing except getting hot.
