Interesting. It's essentially a dry version of an old technology. Quite likely cheaper and more environmentally friendly to boot.

The reservoirs used for hydro power are very enviro-friendly indeed; they hugely benefit wildlife, and probably do a lot to recharge aquifers since the water sits there long enough to soak in rather than just running past.

Regardless... seems to me this could be adapted to small-scale and local, to use any hill in parallel with existing roadways.
