Howdy Robin, Considering the advances the Isrealis have made in their Dead
Sea project research, salt can he heated to some very high temperatures.
Combine the efficency of closed loop freon engines and certain possibilities
can be visualized for standby power generation.

As wind turbine research continues, the vertical style hold the most
promise. Wind can be "enhanced" by use of "shapes" that swirl and
concentrate the wind and induce vortices.See fire storm vids

Wind electric power can be stored. One of the most popular is hydrogen..
however.. heat can be stored using salt, an ideal eutectic.

...and about a thousand times cheaper / kWh than lead-acid batteries (when
done
on a large scale).
