    Earth's Core
    How does Earth's outer core reach the temperature of 5000 degrees and remain liquid, while inner core remains solid?
    The inner core may be hotter, but it is at a much higher pressure. At a fixed temperature (say 5000 degrees), high pressure can make a liquid into a solid. So, even though the temperature increases as you move into the inner core, the pressure increases faster and wins.

    Why is Earth's Center So Hot?
    Why is the center of the Earth so hot?
    It's a combination of radioactivity (the radioactive materials in the Earth generate heat) and the residual heat from the formation of the Earth. When all of the matter that created the Earth fell together, it picked up kinetic energy falling in. When it stopped at the proto-Earth, the kinetic energy was turned into heat. The Earth hasn't cooled yet. The Moon, being much smaller, has had time to cool and probably has a solid core.

    Not so fast, that's not our science lesson, this is it:

    "For several years as uneducated sycophants in the media gushed and fawned over every utterance from former Vice President Al Gore, NewsBusters has informed readers of just how absurd the junk science he's peddling really is.

    Last Thursday, NBC "Tonight Show" viewers got a perfect example of how the Nobel Laureate basically makes things up, and that his poor grades in college were quite an indicator of just how little he understands about science.

    So egregious was his departure from reality that the following clip should be mandatory viewing for all his fans in the media who seem to be just as scientifically-challenged (video embedded below the fold with partial transcript, h/t Hot Air):

    Geothermal power is generated by heat trapped in the earth. Currently less than one percent of power is generated from geothermal energy but the potential is unlimited and more economically viable given new drilling techniques.

    Yes, by all means we should ignore the unlimited potential of geothermal energy because Al Gore doesn't know how hot the earths core is. I guess you were giving us a lesson in conservative logic...

    Kinda' hit a sore spot, huh?

    Perhaps you better take down the Al Gore Shrine, and the personally autographed pics of Old Rock and Chris.

    You didn't answer the question. Should we ignore geothermal power because Gore doesn't know how hot the earths core is? You can answer yes or no. That should be simple enough...even for a conservative.

    No, we should just ignore Al Gore.

    Perhaps you could give the numbers in terms of cost to build, cost to maintain, operational lifetime and energy output expected. If they add up as you seem to think then the energy companies, remember they are not regulated anymore, should be jumping on this as fast as they can.
    The mighty dollar may have fallen, but the capitalists still chase it.
    However, they only chase it where it can be found, and their failure to chase geothermal is a pretty clear indication it's not as viable as you believe.

    Wow, you're so smart.

    I have questions.

    For which scientific field was Gore awarded the Nobel Prize?

    Exactly how old was the earth when God "shimmered" people into being from dirt?

    One of the drawbacks of geothermal energy is that it tends to generate earthquakes:

    Poking a hole in a motile crust is always risky. Remember, the earth was once quite volatile, so we don't want to push it.

    I should always remember that folks like you have to be spoon-fed, teaspoon by teaspoon.

    You see, Al "Failed Out of College" Gore is the Prime Mover of the Global Governance Scam.

    It was in all the papers, didn't ya see it?

    So, it's more than passing humorous that the Pied Piper of Global Governance doesn't know anything about science.

    Get it? Got it? Good!

    And what's even funnier is that folks like you get bent out of shape when Gore thinks he's living on a body closer in temperature to the Sun- and you don't see the humor!


    OK, maybe that one doesn't play well in your schoolyard. Try this:

    Did you hear that the federal government is sending a manned mission to land on the Sun to study it?

    Burned up? No...

    They're going at night!
