Today's lecture is on minerals and energy. Lots of focus on using metals for different purposes and changing their properties over time or by mixing. Limitations to recycling materials. More focus on chemmat. Energy use for decontaminating resources. Abundant and scarce metals. Minerals are just dispersed into other places as a different form. Just have to find ways to transport it back to where of came from. Concentration and location of minerals.
Energy is an important element to our everyday lives and quality of life. Renewable energy isn't stable because of when the energy gets renewed or when it is available. Usually low energy density. Emphasis on stored energy resources running out.
