How big a tank? I think you're going to find a fly in the ointment
once you run some numbers on air consumption. And if air power could
be so efficient and practical, why do you believe it is that
off-gridders, often known to be innovative and unafraid of breaking
with convention, haven't flocked to the concept?

Another fly in the oiment on your battery remark.....if batteries are so
much effecient
at storaging .Why are repair shop using air tools instead battery powered
tools.

For the same reason that I use many air tools in my own shop - because
they're often lighter, cheaper, and more compact than electric
versions. Sometimes efficiency isn't very important.

Now, if compressed air is so much more efficient than batteries, then
why do *you* think that we're seeing ICE/battery hybrid cars driving
around, but not ICE/air hybrids?

Because it is pure PC instead of science for starts.
There are and have been air powered cars...they are lighter for a hybrid
version
than a battery hybrid.Since all you do is add a burner in most cases.
Brayton cycle in a turbine ....Or rankine or sterling in a piston .
