Lecture 8: Electricity pt 2 Nuclear and Fracking

Question 1

nuclear fission

Answer 1

essentially having nuclear resource/fuel in this case uranium in some kind of reactor vessel superheating a special heavy water solution which cycles through this really closed contained system and that superheated material is then back to the basic generating electricity, the water is team rotates the turbine drives the generator that creates electricity

Question 2

uranium

Answer 2

common metal found in rocks, but a nonrenewable source of energy used for nuclear power

Question 3

hydraulic fracturing

Answer 3

fluid pumped into rock at high pressures
rock is fractured and sand keeps cracks open
gas and oil is released HORIZONTAL branches in every direction to crate a bunch of small fractures rather than dig down extract
can gain a lot of resources from a less lush deposit of natural resources
drilling and going out horizontally putting pressure like explosives to create fissures in the rock matrix
erode some material out and release petroleum products

Question 4

Nuclear Waste Legacy

Answer 4

nuclear waste is deadly for thousands of years while many storage devices are only safe for about 50

Question 5

methane

Answer 5

natural gas 84x more potent than CO2 released with fracking
