So iron actually goes from solid, to liquid, to gas, to solid?  Sounds like last night's chimichanga.

It has different properties when it's under high pressure and temperature.

And every time you dig a hole you let some of the heat out. That's why I don't garden anymore. I can't take the guilt of slowly freezing all of us to death.

There's still plenty of radioactive elements in the core and mantle pumping out heat, you trap it all and you'll turn the crust to magma.

This is not new info. Check out this BBC documentary from the 80's

Go to the 19:50 mark. The dude conducted an experiment and found the temp of the iron to be hotter than the surface of the sun.

It's a great series, btw.

There was a book called Richter 10, about a guy who developed a way to predict earthquakes by creating an exact working model of the planet.  Like, a physical model.

If you think that's bad, he planned to take the country's nuclear arsenal and use it to weld all of the faults in California back together. That might work for a little while, but then that whole pesky "rotating core" and "tidal forces" would allow the plates to shift, and the first quake when the plates form a new fault would be a real doozy...

Okay, so . . .   not that the rest of it makes much sense, but what's up with the "saucer to Venus"? Totally doesn't jibe with the rest of the image. I mean. Again. Not that any of it is, well, sane. But. At least it follows a central theme. Why a saucer? Why Venus? The mind boggles ...

on the other hand, HOW close to phase boundary is it?
How much increase in temp is needed to liquify the core?
It was liquid at some point (probably), when did it solidify?

Succubus and Incubi are the same kind of demon, but hey do not switch between male and female form. The way I remember the succubus collects sperm, gives it to an incubus who then goes on to create cute little cambions.

Geo-*COUPLED* is pretty useful as a conservation strategy though... Dig down 10-100' or so just about anywhere in the temperate zone and the temperature is always ~50F. So if you bury your heat-pump coils in a thick layer of earth or (better yet) in a water well, you have a constant moderate temperature within a single-stage heat-pump's 20F heating and cooling comfort range. Water and / or dirt conduct heat far better than air does, so you've got even more advantage over putting a coil-and-fan unit outside your house.

A lot of zoos are using this, as far north as Toronto. If you want to keep animals such as elephants that need huge spaces kept a tropical temperatures, it's kind of a no-brainer as far as geocoupled heat pumps vs. a few zillion BTUs of natural gas heat.

/ has a friend who was part of the Washington DC National Zoo remodeling, part of that was geocoupled heat pumps for the elephant enclosure.

Wolf_Blitzer:

I'm very sad that there was only one "Rendezvous With Rama" book. ONLY ONE!

make me some tea:

PainInTheASP: So iron actually goes from solid, to liquid, to gas, to solid? Sounds like last night's chimichanga.

It has different properties when it's under high pressure and temperature.


I'm still wowed out by an article I read in the 80's about hydrogen taking on metallic properties that they didn't figure out until they invented the diamond pressure cell.

The relationship between pressure and temperature is important. For example, Carbon dioxide or propane or butane are all gases at Standard Pressure and Temperature. (STP) But put them under a little pressure such as a fire extinguisher, a bbq tank or a cheap plastic cigarette lighter and they'll liquify. You'd never see the liquid forms of those in open air.

Heck, I've even (en passant) read that there are parts of Antarctica that have gone below the usually-quoted freezing point of CO2. That doesn't mean that there was CO2 snow there as on Mars, but upon thinking it through (and someone better versed in chemistry please correct me) if you had a chunk of dry ice in a sealed container, it'd stay frozen.

It even has effects here on Earth. Ever read a recipe that has "high altitude directions?" There's a reason for that. At sea-level pressure water boils at 100C. High in the mountains it boils at say.... 90C. A three-minute egg becomes a 4 minute egg. In a vacuum water will boil at any temperature above it's freezing point, and even below that it will sublimate. I think the relevant term is "triple point."

So yeah, when you get to weird temperatures and (in this case) weird pressure extremes, things behave... weird.

The planed Jupiter has to be 10,000 years worth of doctoral dissertations at least.

Another thought: I'm pretty much OK with reactors and shiat, but I gotta say that I would need to see some reeeeeaaaaaaal careful studies and simulations before I would be OK with drilling down 3000+ miles to tap the Earth's energy.
