Solar vs. A2W vs. Geo

Interesting comparison of energy cost per BTU delivered:

Energy-Prices-per-Million-BTUs

While still to be understood how these figures were derived and even what exactly do they include, I see the general idea. What is not there, and would be nice to have is the same for solar and other alternatives. With a very limited data available, my experience (from specific projects) results in the following:

    Solar thermal = $350 / KBTUh
    Air-to-water    = $450 / KBTUh
    Geo thermal   = $600 / KBTUh

Any comments from anyone ?
