fantastic course, should be required for all people turning 21
Anyone else here wanted to raise their hand and jump into the discussion?
Energy = Ability to do work (Communications, Thermodynamics, Transportation, etc.);
I don't believe in "energy scarcity", I believe we've not had longstanding pressure to use anything than the "Grid" that was sold to us like the stereotypical "drug dealer" (try for free->increasing costs once addicted). We've not had climate/cost pressures until lately. The interests most vested in existing supply have an "inertia" to change and have invested heavily in media proliferation of counter-intelligence re: climate impact. Energy policy ("Grid" v. Household Independent) has dramatic impact upon both foreign and domestic policy ("petroleum wars", pipelines, etc.). I also do not believe our system is designed to be efficient, but to maximize profits.
I believe it would be a significant improvement to Homeland/National Security, Economy, Environment, etc. if we migrate our Energy Systems from "Grid" to multi-source, Household Independent Generation and Management. We could revisit the steam engine or aircraft engine designs (efficient by requirements for flight), improve their efficiencies with modern material science innovations (graphene, aerogels, etc.) and achieve multiple improvements over Current_State: Reduction to Elimination of "Outage Rates"; Improved Homeland/National Security (Energy->Communications->Management); Improved Economic Demand by reduction to elimination of Household Energy Cost;
We literally swim in energy, but we hardly harvest it. We turn our systems on and off all the time when we could be winding/unwinding our energy systems all the time. We could store cold during the winter to use in the summer and store warmth from the summer to use in the winter...we just don't.
Achieve better Thermodynamic starting points by using geothermal gradient for both heat source and heat sink. Solar: Concentrated Solar Power, Photovoltaics, Passive; Kinetic: Wind, Water, Vibration, Tide; Chemical: decomposition + advanced pyrolysis...we need to prioritize non-emissions sources, and nuclear's existing problems are at increasing Risk due to sea level rise, educational requirements to maintain, half life v. longevity of nation states, etc.
Primary energy isn't a great comparison for renewables since they have such fewer energy losses. Still love the LLNL flow charts though.
Watching this class in 2020 and it would be interesting to see an update. Is the course still offered?
Same here 😂
Nice course
Infinite energy he wanted the Answer! Because I know nuclear doesn't workm I'm an electrician. So if God back to the grid. So what United should be a implementating quantum mechanics to solve this problems.
You can manipulate electricity but it ain't easy
Infrastructure suffers from the tragedy of the commons.
