	*Bottom line - considering lifetime design - current air storage energy costs are lower than any battery technology. If we go mass thermal + PV, then our system can handle all loads with a 12kW PV system even in winter, provided simply ample thermal storage. Therefore, it is now possible to kill all energy issues, since 2016, when wind and solar attained grid parity with coal.		*Bottom line - considering lifetime design - current air storage energy costs are lower than any battery technology.
