Shermer and Scheyder discuss: rare earth metals • lithium, copper, • aluminum and other precious metals • how much rare earth metals will we need by 2050, 2100, and beyond • combatting climate change • electric vehicles • recycling electronic waste • how lithium-ion batteries work • Can renewables completely replace fossil fuels without nuclear? • how mining works in the U.S., China, Chile, Russia, elsewhere • public vs. private ownership of mines • Native American land rights.

How were coal and petroleum produced? (NOT from dinosaurs!) How much is left? Can or when will we run out? The end of “cheap oil” will happen soon but we will probably not realize it until oil-producing countries can no longer keep up with demand, no matter how high the price. If we don’t phase out fossil fuels, climate change will become even more intense and oil will get too expensive for all but the most essential uses.

The world faces two energy crises: (1) too much, because we are changing the Earth’s climate and chemistry and so inviting global catastrophe; and (2) too little, because the bulk of humanity still lives in poverty, without enough for a decent standard of living. The answer to both is to go nuclear. Upon examination, the arguments made against nuclear energy, including: emissions, waste disposal, accidents, and proliferation are shown to be exaggerated, unfounded, or soluble using even currently available technology.

The Paris Accords have been a failure in reducing global warming. Solar and wind energy have not been the panacea environmentalists promised. To avoid catastrophic economic impacts, the United States needs to keep producing oil and gas until other ways of mitigating global warming can be found. Fracking has helped turn the United States into the world’s leading oil and gas producer. But the health of future Earth relies on keeping a strong economy while we transition away from oil…

Advances in civilization are driven by the availability of excess energy. As the human population has exploded over the past two centuries, the global consumption of energy has also drastically expanded. But the current economic model is unsustainable without the development of a clean, unlimited source of energy. Space-based solar power (SBSP) can directly access the power of the Sun, and has the potential to be that clean, unlimited baseload power source of energy for the entire planet.

Entropy keeps the arrow of time moving; today is less ordered than yesterday, and this is certain. If we extrapolate this concept backwards, through our scientific narrative to the origins of the universe, then we must postdict a universe that was once ordered only through its lack of movement, which means it was frozen. But even then, as Galileo once said of the Earth, eppur si muove, but it does move. And if it moves, it creates heat, and understanding…
