Big Water Projects

I am not a nature freak, and do not consider myself environmentally active. I see a lot of the environmental propaganda, and it usually ticks me off that they are so slanted and usually are either flat out dishonest, or leave out the full story. However, I do believe that we are stewards of the world we live in and will be held accountable for how we treat it. Furthermore, I think we as a species often do things that are less then optimal, simply cause we don't want to take the time to figure out the optimal or because we just can and we don't like anyone to tell us that we can't.

One such activity that can be handled this way are the building of huge dams and reservoirs. I can understand that we often have a need to collect and store water, and that a reservoir is often the best way to go about it, but too often, we are building these things for electricity and not for water storage. There is a better way. What brings this to mind are some articles I have read about the Belo Monte Dam Project in the Amazon. It is a hydroelectric dam, and not intended for water conservation. Unfortunately, it will destroy millions of acres of amazon rain forest. More so than that, the indigenous locals are completely against it. If they were all for it, well, even though the amazon is the lungs of the earth, it is their home, and really their vote should matter more than anybody else's vote.

Here is a better way, that won't cost as much, will be more resilient, won't take as long to start providing benefits, would destroy hardly as much amazon rain forest, and might even be well liked by the locals. In-stream generators. A large series of small dams or dikes which then sends the water through small hydroelectric turbines each involving a vertical drop of only a few feet, not more than 5 or 10. Yes, there would still be some forest loss, but a tiny percentage of what the current plans entail. Each dam or dike would be a small separate project, but would be able to be put in much faster. You still get the hydroelectric benefit, but now you have much smaller localized generation units, but in a mass quantity. If one has a problem, the others are still fine. They could also ensure a more regular flow without the flow stoppage involved in the larger dam. River wildlife would be virtually unaffected in the long run. Sure this is different, but wouldn't it be better than destroying so much precious rain forest? It would be a lot easier to replicate lots of other places, and could be scaled out to meet demand on a much more continual basis. How about it folks. Who is in favor of a better way?
