Nuclear reactors do nothing to global warming. Simply just steam. Global warming is something entirely different, think of a green house. The pollution has cause the rays to be trapped, thus staying in warming the Earth. It only stays in the atmosphere for a small amount of time. @stickman101(View Post) Mostly heat is made through the plutonium and decaying radioactive elements. It might work, but only for a slight amount of time. Once the elements fully decay, there's nothing else to be done.
@stickman101(View Post) I mean, we can;t keep shoving elements in the center. We'll eventually run out on Earth. It would require a massive amount still. Space is not an option for these elements because it's too expensive to mine the heavy metals and ship them back. then drilling down is even tougher. The most we've drilled down is 5 miles. Haven't broken the crust, and then it would take a ton more time getting to the center and no material would survive the crushing pressure.
@shroom207(View Post) You wouldn't burn to death unless you were the drill And the crust (On the continents, not the ocean) ranges between 30 to 70 km thick In the ocean, 6 to 11 km thick.
