Use a blimp.

That seems commercially feasible for the logging
industry but only a few bicycle sheds will accomodate
a blimp without knocking out a few walls.

What are the economics of taking a blimp up and down a mountain?

Now that I think of this, the question seems moot: if the economic
good is at the top of a mountain, it should be easy to get it down:
one only needs a method to control free-fall. If useable amounts of
power can be harvested, that's a side benefit. There's no energy cost
in lowering your commodity, the economics is in the start up and
maintenance costs.
