Tidal power is not just being explored. It has been in use for centuries along with many other things that we've lost touch with.
It is just that the "white man" is just now getting around to these things. The white man re-invented the printing press, and since he was unlike the many other cultures around him and did not see a threat or forgot the danger in the printed word, ended up running with it, and went on about Man's accomplishments, and how smart and grand he was, how the species was evolving etc. Then went on to write his own version of history which claims that the world was uncivilized until the white man came to redeem it and rescue it from the jungle.

Taking credit for many things that he learned or stole off the cultures before him, re-writing history, and re-shaping God (or killing) in his own image (bunk science, reason, and near sited philosophy). How often we forget that most of us only use 10% of our minds, and that most of use put too much emphasis on being clever and calculating and forget about those other elements of our being that make us into full human beings. Also we forget that 80% of us, even our intellectuals are very easily persuaded, hypnotised, and induced into psychological, spiritual, and emotional sleep.
If one will but tune into the History Channel (regardless of how much I don't trust them or any mass media form of education), and watch the show Ancient Aliens, remove the aliens and silly theories and just observe the mysteries before you, you'll begin to quickly get an idea that what we have been educated to be human history, is yet another theory, and many mysteries have (until recently) been rejected by main stream thought because the problems they presented to our current line of thought were too troublesome.
The human race is deeper and capable of more than we may ever know, and we would be nothing if it were not for the mysterious source that created us...
...a source that does not play favorites.
Anyhow, this is not an anti-white rant. Tiny Tim was white, and he ruled my worl!!!
And I do have Irish blood in my veins, I'm pretty pale and pasty, plus my Cherokee ancestors were pretty white them selves (dunno what happened to my Shawnee tan).

The point is that historically where ever the white skinned people went, things fell apart and cultures, lives, and history was lost on a large, global scale. As a result, "white" has become synonymous with such mass destruction in my mind and most of the world. Hence the term "The White Man's Burden". For no other race or culture has conquered the planet quite so successfully.
There, now I hope my final explanation saves me from getting stoned at the next Amiga meeting I attend. Then again you are Amiga users...
...though Amiga history is not quite the same as having your history, culture, and ancestors all but wiped out from the earth. It does have certain similiarities none the less, but I won't go into the history of that as you all know it well. :/
