GGR333H5 Lecture Notes - Lecture 7: Directional Drilling, Cryptocurrency, Internal Combustion Engine
Document Summary
Shale powers us oil: we see more oil being produced now than in the last 47 years. Cryptocurrency mining: the changing supply and demand of energy. Early steam engines weren"t really efficient it only discovered that it could make things moves giovanni wanted to know if we could harvest this movement. Efficiency the ratio of inputs to outputs. The laws of thermodynamics: 2 when dealing with heat, it is impossible to get 100% efficiency. Early engines we see use the expansion processes compound engine we look at the explosive energy and use this to move a piston. What are the drawbacks of heat/thermal engines: they have heavy material components, we see a major loss between these two processes. Climate change and global warming as a heat engine. Heat engines being used as an analogy for what"s happening to the environment.
