This actually seems like the more ecological design, as the concrete used for weight here would be less than the amount used for a dam, and you wouldn't also have to pervert the flow of a river in order to build it. Besides, one time costs are trivial compared to running costs of industrial processes in terms of the environment, especially in terms of power production.
- konschubert 8y ago> as the concrete used for weight here would be less than the amount used for a dam Think that through. A dam probably holds 100 or 1000 tons of water for every ton of dam material. A concrete weight holds exactly on ton of concrete for one ton of concrete weight material. And "amount of weight helt", be it water or concrete, is Exactly what matters here.
