Thanks to those who responded. Answers: Not dependent on internet.....I think there will always be a need for dams if water storage is important. But it could reduce the size of the reliance on dams, most of which is for the power. That means less ecological disruption and fewer potential disasters. It also means that one could make reservoirs nearby in better locations closer to the point of need instead of disturbing the flow of the river. The point is that we can widen our tool chest.....Yes, it would be good for rural areas. We are just starting to produce some small ones with 3D printing for that kind of use. Any ideas for customers?
