But it all comes down to the sun ... why are the thermal plumes hot?

Then again you could say they are hot due to nuclear reactions in the earth's core. Ho hum.

And on the river flows ...

Might as well say, yeah, I forgot about thermal activity...stupid me.
Okay, the only sources of energy the earth has is the SUN, thermal, and nuclear.
I think I am correct now..human bodies don't make energy...done...I no longer am a part of this thread... Suck it down.

(why didn't the robots use animals? or breed ppl that didn't have brains? THE ROBOTS ARE EVIL!)

Yup, they've got sick twisted CPU's!

The fususion thing would be a solution, but they'd still run out of water, eh sometime...if they didn't get out to space...

To get energy from a chemical reaction the reaction has to be spontanious, or a decrease in Delta G. Chemicals, only react spontaniously when they have energy output as the result. This again means releasing they're internal energy.

This means that you can't make the reaction go backwards unless you put the same amount of energy or more into it. And eventually you would run out of reaktive chemicals.

The same principle for the planet core. It won't be hot forever, if the sun doesn't shine....

Now just what has the sun shining, got to do with the planets core -besides which all power sources are finite.

Before someone suggests black holes or any other idea of that approach, do your research blacks holes are now thought to be finite(Hawking), though I am not sure about the Kashmir Effect.

Kur0s: Tell ME why the planet core will be hot forever...what makes it heat up?...and where does the heat go? And don't tell me fusion crap...because that's a finite resource, though it's very large. And black holes has nothing to do with nothing!

you missed the point, all power sources are finite - I agree - read the post again. As for the core thing, it being hot is not dependant on the sun shining now is it !! Think before writing !!!!!

Black holes were thought as a way of harnessing EM forces to generate unlimited power. Anyway, enough of this

The core of the earth is kept hot by
Heat and pressure and tidal forces (gravitational tides)so it does need the sun to stay hot(well not the sun but the gravity the sun produces). (God I'm a geek)
A black hole could be used as a power source as long as you had stuff to feed it. Black holes emit Heat, light (from stuff dying above the event horizon), hard radiation (x-rays, gamma rays)
Now, if you had a Quantum black hole (black hole with the diameter of a single atom) you could use this as a power source. (Groan, I have reached new heights of geekdom with this post)
This is still a finite source of energy because sooner or later you could feed the entire universe to it.

That is of course if you subscribe to the belief that the Universe is finite. Just my 2 rupees on the matter. I like where this discussion is going. Keep it up!
