  • People just feel like there has to be a catch with renewable energy and latch onto the idea of rare earth metals. Besides cobalt having some use in some kinds of lithium batteries right now, theres not really rare earth stuff going into renewables. Solar panels are silicon and aluminum, wind turbines are simple machines connected to a magnet spinning inside coils of copper, lithium batteries are already being made with iron as the other component.









  • oh yeah I know all about it. Technically, quicksand is sand suspended in water. It has non-Newtonian properties, sand particles are able to slowly move around like a fluid, but if they move too fast they lock up. So you can sink into it slowly, if you struggle too fast it locks around you. But more commonly the term is broadened to include deep mud pits, usually clay silt, and peat bogs. All of them are denser than water, so there’s no real danger of sinking under, you’ll float around chest deep. Though you can push yourself under.
