Fun facts and wild ideas.

If the Earth was the size of an egg, the Earth's crust would be 5 times thinner than the shell of the egg.

On this thin thin crust we dig/drill for oil, gas, coal and search for plants to burn for heat. Just below the crust is an unimaginable amount of thermal energy.

The purposed XL-pipe line is 1,179 miles. The Earth's crust is on average only 25 miles thick. Why are we looking to drill horizontal and not vertically?

It is almost comical that we work so hard to find different energy sources while floating around on a blob of molten rock while living on a thin layer of ash.

I haven't done any calculations, but in terms of "Global Cooling", how much energy would be have to extract to lower the average temperature of the Earth's core by 0.001 degrees? I'm guessing it would be several millions of times more energy than the entirety of all the energy used by humans in all of history (& prehistory).
