With the energy source (presumably solar/wind) being "free," efficiency isn't the most important thing. But the whole thing sounds sort of "Rube Goldberg" even if it works, batteries or supercapacitors or something like that are probably going to be a lot more reliable.

It's sort of like arguing for going back to steam engines because we've got a new way to boil water.

A large portion of power comes from new and exciting ways to boil water that turns a turbine ;)

Most fossil fuel plants are water boilers as are all nuclear plants.

There's even some solar power plants that are effectively just water boilers.
