This This is another underdeveloped source. If you drill down into the Earths crust, at first the temperature drops, because the suns warmth cant penetrate. But deeper, the temperature rises. Volcanoes are evidence of this - molten lava is pretty hot! That well of energy is there to be tapped. As always, the final conversion process is the familiar steam turbine. And, like solar energy, it is environmentally friendly, provided you dont accidentally trigger a local volcano! But it is not as simple as it seems. The process of taking heat from a hot rock cools the rock locally. Theres plenty more heat surrounding it, but can it flow quickly enough to your collectors? Again, its another technology whose time will come, but not a panacaea. -851 We are going to skip significant details relating to magnetics and take a leap of faith; here we describe the effect seen when an alternator is turned-either one that has a built in voltage regulator, or one that does NOT have a built in voltage regulator. This discussion assumes that the terminals are connected as they would normally be, and no additional details will be provided for this discussion.
