Advice to Pres. Obama: go for wind power | 90 comments (90 topical, editorial, 0 hidden)

Re: Plan.. (none / 0)

Actually the accusations are probably true. Wind power can slow the motion of the earth. Using the forces of the tide definitively takes its energy from the rotation of the earth, and the more friction the tide has to overcome, the more energy gets lost from the rotation.
But with ~ 10^26 J stored as rotation energy, this is not a short term issue to worry about.

However, I think you can run some distance in front of the tide, to speed earth up again. The trick is more to be in the right position to the moon, than to run ultra fast.

Re: Plan.. (none / 0)

if you want to go into great detail, skyscrapers increase friction enough to slow rotation, but it's offset by clearcuts in the Amazon. Can't imagine you want to quibble on such insignificant detail.

Or do you want to discuss this with the two Hopi brothers who control poles and rotation?

What are Hopi brothers?

I didn't want to quibble with YOU, but yes, with regard to the question if despite conservation of angular momentum (for sure on the scale that matters) it is possible to change the speed of the rotation by moving around on earth and how.
If I wouldn't care for irrelevant stuff, I would have the wrong job.

Re: Plan.. (none / 0)

In this thread i was just having some fun. In Hopi Indian cosmology, the tilt and rotation of the Earth is controlled by two brothers who live at the poles. Mythology says they shift every once in a while.
