Hot Water, Hot Earth
Calopteryx notes a New Scientist article on the discovery of "supercritical" water emerging from a vent in the Atlantic Ocean at 407 deg. C (765 deg. F). One of its discoverers actually said, "It's water, but not as we know it"; it's the hottest water ever found on earth. The cause seems to be a huge bubble of magma beneath the ocean floor, 3 km below the sea surface. Meanwhile Nymz shares a journal entry on a hot spot on land: a 2-acre patch in Ventura county, in California, that has heated up to 433 deg. C (812 deg. F). Here geologists blame buried hydrocarbons burning as they get access to air through cracks in the ground. That high temperature was measured a foot below the ground surface.
Burning hydrocarbons?! Sounds like a good place to put a combo drill/refinery/gas station!

Buy an electric car TODAY people! That petrol is causing the ocean to heat up... Wait, what? Magma? Really? Wasn't that around before we invented cars?
Hang on folks, I'll have to get back to you...
It sounds like hot fire is already present, throw in "hot heart" and you've got yourself a hot captain planet!
