It must be true, Al Gore said it:
Conan: Now, what about … you talk in the book about geothermal energy …
Al: Yeah, yeah.
Conan: and that is, as I understand it, using the heat that’s generated from the core of the earth …
Al: Yeah.
Conan: … to create energy, and it sounds to me like an evil plan by Lex Luthor to defeat Superman. Can you, can you tell me, is this a viable solution, geothermal energy?
Al: It definitely is, and it’s a relatively new one. People think about geothermal energy — when they think about it at all — in terms of the hot water bubbling up in some places, but two kilometers or so down in most places there are these incredibly hot rocks, ’cause the interior of the earth is extremely hot, several million degrees, and the crust of the earth is hot …

In reality, the temperature at Earth’s core is closer to 8,000 degrees Farenheit. If it were several million degrees, we wouldn’t be a planet, we’d be a star.

Hey, Al, maybe that’s why the Earth has a fever!
You’re not suggesting that we should rely upon Algore’s scientific credentials, are you, Doug?
The amazing thing is that people come away from these sort of things with a genuine belief in them.
Does anyone else think Al Gore looks really really creepy with the gray hair?
