makes you think...

Arent ocean currents a form of perpetual motion an endles stream of energy you can harvest only we prefer to burn coal and oil?

This looks straight out of the beautiful imagination of Vincent van Gogh!

Not *strictly* perpetual: ocean currents are caused by winds, which are in turn caused by the earth's rotation. And the earth's rotation is slowing down, infinitesimally, all the time.

But your point is valid and there are many research programs to this effect: http://ocsenergy.anl.gov/documents/docs/OCS_EIS_WhitePaper_Current.pdf

No, winds are just currents in air that is 1000 times less dense than the surface water, and maybe only 10-100 times faster at best, their effect on currents small. The earth's rotation, the moon's gravity, the sun's heat, plus any underwater volcanoes and vents all supply energy into the system and the underwater topography funnels the effects of these to provide the startling display we have just witnessed.

Isn't this actually animation? Not "time lapse"?

Now, that would depend if this animation was an approximation or based on stats taken from actual sensors placed in the water to record water flow speeds. So... An animation of a time lapse maybe...?

Sure they're some pretty pictures. But think of the volumes of water moving in this. Think of the energy needed to move it all. Bloody hell.

All I have to say is, when you're visiting Easter Island, do NOT swim too far out...

yep, the amount of power in tides and currents is staggering. The problem is harnessing it.

Seems legit.
When I hear the term "time lapse", I think of something recorded in real time that is sped up because, in reality, the actual event is very slow. Not something generated by a computer. An animation of anything is just that, an animation. imo....>> ^Sagemind:

Well, if you think about it, it's all just representations of reality, whether it's an CGI animation made up of calculated data or the actual snap shots played continuously as an animated sequence of stills. (Also, consider other "videos" or images of phenomena in outerspace: black holes or so-called dark matter. We have to recreate images and video based upon various different observations. So I think while, yes, it is animation, you're losing out on the grandeur of the video by dismissing it as "animation".

I'm not "dismissing" it, I'm just calling it what it is. If someone tries to sell you a pile of dogshit by calling it cotton candy most likely you won't buy it. Because you know it's just a pile of dogshit, not cotton candy.Different representations of reality are called different names for a reason. Because they are different. Animation is animation, not time lapse. That's all I'm saying.>> ^poolcleaner:
