[ RadSafe ] solar advances

Joe - I doubt that farm / grazing land will be significantly impacted.
There are just too many more appropriate places close to the demand. I
suspect that usage will be rooftop, landfills, and other unusable or fixed
structures to distribute generation capacity at the location of the load.
Los Alamos has constructed a photovoltaic "farm" at the public landfill,
for instance.
