Common sense isn't.

The Tennessee Valley Authority recovered less than half of its $36 million investment in a failed power storage process in Mississippi, according to a financial report released Tuesday. In its latest quarterly report, TVA said a venture organized by the German conglomerate RWE paid TVA $15 million on April 30 for losses from the canceled project.
TVA had invested $36 million in the venture, known as Regenesys, before the project was canceled because RWE didn't want to proceed with the joint venture through its Innogy Ventures Ltd subsidiary. Regenesys was designed to act like a giant battery to store energy and improve the reliability of TVA's electric service in Columbus, Miss
~~~~~~~~~~~~~~~ Editorial Notes ~~~~~~~~~~~~~~~~~~~
Moving to highly intermittent sources of energy like wind or solar PV entails either a proportionately larger (80% to 20%, some say) "base" source for electrical power (like gas, coal, nuclear or steady hydroelectric); if there was a way to store large amounts of intermittent power and release in a controlled fashion to the grid that would enable a larger % contribution from wind and solar. So, there are a lot of schemes out there to capitalize on this future need. [This is] one that didn't make it; what could be simpler than a giant battery?

|Quote of the moment|
|Throw hither all your quaint enamell'd eyes That on the green turf suck the honied showers, And purple all the ground with vernal flowers. Bring the rathe primrose that forsaken dies, The tufted crow-toe, and pale jessamine, The white pink, and the pansy freakt with jet, The glowing violet, The musk-rose, and the well-attir'd woodbine, With cowslips wan that hang the pensive head, And every flower that sad embroidery wears.|
|~ John Milton, Lycidas. Line 139. ~|
