Seems like this would be more cost effective as a component of sky-scrapers. Generator on top, series of weights on rails down the sides.

Not even close. First a 1KM tall skyscraper? Second they are talking quite a lot of weight - the skyscraper would have to be MUCH stronger.

No, the additional load is not worth it. It would be one of the least sustainable things you could do due to all of the heavier columns you'd have to use.
