ok. i am lost now... can we go back to


BUUZZZZZ-ZAP ?????

leave it on the counter, ladies.

Are those the notorious topic-hijackers complaining? Isn't it nice to ask several times to get back on topic?

Apart from that irony (if I am not mistaken about identities here, of course), I think, the current discussion is one of the more interesting ones. I don't know myself which of the theories is closest to the truth, since there's much that has to be taken into account, but I read it with interest.

[grayjaket]

OOhhhhhhh ok! At least someone's having a good time *turns off brain* There...much better, forgive the intrusion! Continue continue, you have my permission now...yes yes, no thanks neccessary, I'm quite happy to assist.

I was thinking more in terms of the slight effect that cities have on the movement of tectonic plates and weather patterns. Not to mention cities are what brang about increased production and technology which brought about the ability to remove mass from the Earth in as large a quantity as is now possible.

so what you are saying is that humans are slowly "eating" the earth and that is messing up the rotation, and therefore humans are bringing about the end of the world just by burning resources and making skyscrapers....?

Cows contribute to the greenhouse effect by releasing methane into the atmosphere.

I was contributing a lot to the greenhouse effect last night, then.

[The Industriallist]

The Greenhouse effect would actually cause an increase in the earth's mass. Less heat is radiated, causing the temperature to increase, and the heat energy raises the mass. Although that would be a very minor effect.

Hydro-electric power is entirely inside the closed system. There is no way it will effect overall rotational momentum

[Meh]

Is it true that if the mass moves farther out from the center of rotation the mass that moves is moving quicker and to conserve angular momentum that the rotation whould have to slow down?

[west]

Yesh.


As far as I know.

[kroner]

he's right that it wouldn't change the rotational momentum, but you're right that it would increase the moment of inertia which would decrease the angular velocity.
rotational momentum = moment of inertia x angular velocity

[Meh]

I thought it was something like that. So damming rivers does slow the rotation. Hard for me to remember all the specifics. Somehow I can drive the car without thinking about the friction and chemical reacations involved.

Ever use a home made corded electric lawnmower? Pretty easy to make. Pretty scary to use.

The greenhouse effect might, however, increase the rate at which gas escapes from the upper atmosphere. I could be wrong. The upper atmosphere can be a very odd place. Of course, both these effects are minor effects that will probably be masked by random meteoroids.

[The Industriallist]

I guess the thought that your shoddy workmanship migh break up and hurl the blades at you would be a little unnerving. If I attatched a lawnmower blade to a powerful electric motor, I really don't think I would be putting it on a lawnmower chassis. More like the front of my car... if I had one.

Thanks for the return to topic.
