Here is new Zealand, we are not allowed to put anything in the river without navigating a massive bureaucratic labyrinth that of course acts as a fire wall to stop 99.99999 percent of people - I am all for the environment, but at the end of the day, I would like to be able to use it as well for my means, if I owned property - without paying thousands and thousands in lawyers bills - the best way I think, in New Zealand, is to own a boat - I looked into this many years ago - and if you own a boat, then many things open up to you - because rivers are part of the "queens chains" so allow you to have certain freedoms - if your boat was moored, lets say, and then have some type of generator on the side then it might escape laws here - I know the same thing happens with tax on housing if your house is on four wheels - like my house bus.
About Dams, here in new zealand we have many forms of power, we are just not allowed to tap into it - rarity of recourse is very profitable. Can never have abundance. Must never have abundance - otherwise the slaves would start enjoying their lives too much.
I was just reading about Valencia the other day and the flooding - so yeah, I know what you mean. Whatever the case is, I have no faith, whatsoever in anything that is put forward - if they want to remove all the dams, then its most likely because they want to destroy that infrastructure in or to fly people over to the rebuilt one, which they control. Nothing they ever do, is for good reasons. So with the removal of dams, I don't known if it causes flooding, but it would not surprise me if that is what it did cause. But then if its not that, its no doubt something equally as sinister. We will see what the removal of that level of energy does to their countries in the long run.
Thanks!
