A google search of "elevator return energy", found that modern elevator systems in tall buildings do have special drive mechanisms that generates return energy when the elevator is going down. Thus, the complete needed technology for storing residential solar energy in a special heavy-concrete-weighted solar energy storage elevator is already available. The "overall energy" use for tall building elevators is very small ( just the cost of resistance and inefficiency ). No explosive hydrogen.
