Rather than dig only a few feet under the surface to access the consistent temperatures commonly leveraged for residential geothermal systems, an Enhanced Geothermal System (EGS) digs thousands of meters into the ground to capture some of the intense heat that escapes from the Earth’s core.
This heat is used to boil water, which creates steam and ultimately drives turbines that generate power. Pretty much the same thing as current power plants except EGSs don’t need fossil fuels or radioactive fuel rods to make it happen.
If implemented successfully, we could generate power 24 hours a day without concerns about the rising costs of fossil fuels or the hazards associated with nuclear power plants.

I’ll say I’m a crazy one because HipHop is my vehicle to scientific and universal enlightenment. Growing up in the 70s and 80s in Stanton Island in Brooklyn, I was not readily exposed to the hard sciences. You see science existed in tertiary forms during my youth. And it wasn’t until my music career matured, that I began to pursue or I was exposed to science as an intellectual pursuit. But yet still as a child I often wondered about the static from the coffee or the aluminum on the TV antenna… ”-GZA at TED x TEEN 2014 #Gza #wutang

“Having many moons, apparently, helps make you a planet in the eyes of people on other ones, as having children was once said to make you an adult. One’s planetary distinction is redeemed, by this measure, by the clear presence of the orbit of the littler ones around you.”
