Elon Musk managed to get off a lot of really pithy comments in his recent appearance at the National Governors Association meeting – he spoke of a future in which gas-burning cars will be like horses, and explained how China has taken environmental leadership away from the US. He also discussed the personal sacrifices required of a superhero, and his failed efforts to exert a positive influence on America's Climate-Change-Denier-in-Chief.
Well, let's squeeze just one more juicy post out of that orange. Elon also described, in simple and engaging language, how solar energy will power the world of the future. He began by noting that, in a sense, we already live in a solar-powered world.
"The Earth is almost entirely solar-powered today, in the sense that the sun is the only thing that keeps us from being at the temperature of cosmic background radiation, which is 3 degrees above absolute zero," Musk explained.
"The amount of energy that reaches us from the sun is tremendous. It's 99 percent-plus of all the energy that Earth has. People talk about fusion…but the sun is a giant fusion reactor in the sky. It's really reliable. It comes up every day. If it doesn't, we've got bigger problems."
