If you haven’t watched the video yet, please do so and pay special attention to Gore marvel at the advancements in drill bit technology “that don’t melt” in the earth’s super-heated crust. Conan then says we’re “probably drilling deeper than we’ve ever drilled before.” Um, no.
Gore might be able to say he misspoke when he said the earth’s core was “several million degrees,” but he also talked about drilling down two kilometers as if it were a breakthrough, when less-than-state-of-the-art drills have reach far greater depths. I’m not sure how he gets a pass from anyone in the scientific community on this one.
To put into perspective how far off Gore is here, the deepest hole ever drilled is the Kola Superdeep Borehole, which reached a depth of 12,261 meters — that’s more than 12 kilometers, Al. That breakthrough depth was reached back in 1989 — by the Soviets. And since Al is interested in how hot such a hole might be, the temperature at that depth was reported at 356°F, slightly cooler than Gore’s stellar estimation.
