"...no matter what the temperature of the outer core is, and most likely it is quite high, the mantle is cold, and its rigidity increases with depth, because otherwise seismic wave velocity cannot increase with depth, for example for P waves from 6-7 km/sec in the surface layers to about 14 km/sec at the mantle-core boundary." -- Stavros T. Tassos, seismologist, October 2008
Via Watts Up With That: Gore has no clue – a few million degrees here and there and pretty soon we’re talking about real temperature.
Temperature of the sun’s corona: 1–2 million kelvin
Temperature of the sun’s photosphere: 6,000 kelvin
Temperature of the Earths mantle, more than “2 kilometers or so down”: between 500 °C to 900 °C (773 to 1173 kelvin)
Watching Gore make a complete scientific idiot of himself on national TV: priceless

OIM,
Your convictions in wimps beaming, probing, and creating fair maidens for playthings far exceeds all the psedoscience requirements, and it absolutely qualifies you for Lilly times.
Gore is an ex-politico and a lawyer not a scientist.
OIM,
Did you have good Purim(?) celebration?
Al Gore is criminally insane.

New techniques are coming out all the time to be "more green". Kiri Trees are amazing plants, I grow them for the sheer joy, but they also pull in a lot more CO2 and turn it into more O2 than most other plants do... they have a high ignition point as well which is handy for people who live in fire hazards... and the wood is highly valuable... the leaves are perfect fish food as well...
Pulling water out of the air for hydroponics, and then using aquaponics (fish farms, where the poop and dirty water feeds plants) in conjunction... free water, free vegetables, free fish... free kiri fish food... all healthier than most people are used to.
I think putting this together would take a dent out of world hunger, and would increase drinkable water to many people... I work in hydroponics, and I think about ELIMINATING world hunger everyday. Al Gore always makes me sick... what he could do with his money alone, and further still with his voice/audience... instead he spends his days like a useless old pigskin shoe, being chewed by a dirty old dog with rabies.
It is important to distinguish between what Al Gore says (that the core of the earth is "several" million degrees) and what real science says (yeah, what does real science say Earth core temperatures are OIM?).
According to this chart....It only takes 100 degrees celcius to boil water at one atmosphere (101.3 kPa), but it does indeed take more than that to create superheated steam vapour though (374 celcius), which means that 500-900 celcius is just right for a turbine, with upper temperatures allowing for maximum theoretical efficiencies (freezing surface temperatures) of around n=100x(900-0)/(900+274)=76%.
QF,
"yeah, what does real science say Earth core temperatures are OIM?"
I have no idea QF but I'll bet you $10,000 that whatever mainstream science claims is the temperature of the core is not just simply wrong but wildly and grossly inaccurate.
How would you disprove what mainstream science says in order to win that bet, OIM?
How would they prove it in the first place?
I don't exactly know, but I would assume that they assume a linear heat gradient of some sort. All Gore, apparently, assumes some kind of exponential gradient, lol. Your disproof of Al Gore's claim (millions of degrees in the Earth's core), OIM, requires you to utilize other scientific estimates though (the sun's core is 1-2 million kelvin and that the sun's protosphere is only 6000 kelvin), as well as one vague temperature range estimate (500-900 celcius at 2 km below Earth's surface).
Aside from Al Gore's high probability of being incorrect (based on the assumption that such high temperatures can't exist in Earth's core), I'm not seeing where you've disproved his claim.
