Oh dear! The point is well made elsewhere ~ this is a very (italics) silly article.

For instance, the author complains that, after a while of extracting heat in a ground source heat pump installation, the ground source cools! This would have to involve (because, as he states, he and his confederates have done the measurements) that he is actually using a thermal collection coil that is some thousands of miles deep moreover covering the whole of the planet... The planet continuously generates heat!

Other respondents appear totally ignorant of the Laws of Thermodynamics and how subsequent losses in high tension power transmission effectively limit the maximum efficiency that can be obtained from electricity generation.
