Its a variation on a gravity battery.
It can't compete with the energy density, efficiency or fast charge time of a lithium battery.
It might do ok in some niche areas although I don't think market investors would finance it.
Only governments and states will subsidize it and experiment with it. Its not ready for prime time.
