Blades can interfer with bird flight. Remote power generation: Coal and it's problems. Gas and it's problems. Nuclear and IT'S problems. Hydro and it's problems. Nothing is simple, clean and save.

There /is/ the relatively high expense of construction, the inevitable destruction of at least some natural environment, the seeming rarity of places suited for construction, the long distances from such locations to major electrical connection points (cities, substations, etc.), local community resistance to construction (NIMBY, mostly)...

Lot of ecological side effects. Good for short term flood control, but may cause problems long term. A lot depends on the area where the dam is located. Roger (K8RI) |

Here in the west there is considerable pressure to dismantle the dams already in place. They are being blamed for weak salmon runs (as if over-fishing and the recovery in the seal and sea lion population have had nothing to do with it), concentration of heavy metals near the dams, flooding of "critical habitat," and just about every other sin people can think of. There are environmentalists who believe that the worst possible thing that could happen to the earth would be for someone to discover a cheap, non-polluting source of energy. -- Waddling Eagle World Famous Flight Instructor |

These are the same people who think that we should get rid of all the people
of the world except for a few hundred of their fellow believers. "C J Campbell" wrote in message news:200710240644108930-christophercampbell@hotmailcom...
