I would like to know what is the basis for the parenthetical statement: (or switching from coal to far more efficient natural gas). This appears to defy thermodynamic principles.

What is meant by "if effectively solved" in referring to thermal energy storage? What problems need to be addressed? There is a body of literature published by ASHRAE on both heated and cooled storage, including solar thermal systems. If there are problems that have not been solved, I believe that the members of ASHRAE Technical Committee 6.9 would like to know about them.

This is good news, indeed. Now, if we can just get Guadalupe County located on the east side of the New Mexico/Arizona border!
