"If you go outside the studio right now and you find a rock that's the same size and you ask how much energy is in that nuclear energy? The answer is about 100 times more energy than the chunk of coal." "Every single rock that you pick up outside of the studio is as if you're holding a 100x chunk of coal in terms of energy. If you take those trace amounts of uranium and thorium, and you were to fully fission those in a fast reactor, you would get 100 times more energy, which is, to take our original example, enough to propel you about 30km... off of the Earth. So about a third of the way to space..." @isaiah_p_taylor
