Capitalism: Success, Crisis and Reform (PLSC 270) Professor Rae discusses the case TXU v. EDF, about an electric company private equity deal that involves environmental interest groups. Professor Rae structures the discussion by contrasting the deal as viewed from the perspective of Austin, TX and Washington DC. Actors in both locations prioritize different aspects of the deal differently. The case highlights the importance of the "custom...more
Capitalism: Success, Crisis and Reform (PLSC 270) Professor Rae teaches the SELCO business case, about a distributed electric power generation scheme targeting rural Indians. In presenting the case, Professor Rae discusses several analytical frameworks for thinking through business cases, including SWOT (strengths, weaknesses, opportunities, threats), and the Porter Forces. Issues with SELCO's business model are discussed, including the ...more
Transmission Challenges -- Central station renewable energy sources, such as wind and thermal, are most promising and easiest to develop in remote places. Ensuring that there is sufficient electric transmission capacity to deliver this power to market and deciding who should pay for the transmission lines are major challenge now facing many state and federal regulators. Deregulation and Its Role in Promoting Renewable Energy -- Wholesale c...more
Fundamentals of Physics, II (PHYS 201) The electric effect of a changing magnetic field is described using Faraday's Law. The direction of the current so generated is given by Lenz's Law. The operation and energy accounting of the generator are described. The concept of inductance is introduced. The Betatron is described as an example of Faraday's Law. Self and mutual inductance are introduced. The energy density in a magnetic field is de...more
A discussion of issues related to small hydro development; There is a tremendous amount of oil trapped in Canadian tar sands and U.S. oil shale. There have also been repeated efforts to promote the development of a market for synthetic gas, derived from coal. For all three, economic, environmental, land-use, and energy payback issues dominate the concerns. State and federal law play a key role, as well; Many leaders talk about a hydrogen f...more
Fundamentals of Physics, II (PHYS 201) Ampere's Law is used to find the magnetic field generated by currents in highly symmetric geometries like the infinitely long wire and the solenoid. It is shown how magnetism can be used to convert macroscopic mechanical energy to do microscopic electrical work. Lenz's and Faraday's Laws are introduced. The latter says that a changing magnetic field generates a non-conservative electric field. 00:00...more
Within a lecture on biological resolution, the synthesis of single enantiomers, and the naming and 3D visualization of omeprazole, Professor Laurence Barron of the University of Glasgow delivers a guest lecture on the subject of how chiral molecules rotate polarized light. Mixing wave functions by coordinated application of light's perpendicular electric and magnetic fields shifts electrons along a helix that can be right- or left-handed, ...more
Introduction to Renewable Energy Options and Potential, and Electric Systems; Federal, State, and Local Efforts to Promote Renewable Energy (PURPA, EPAct 1992, and EPAct 2005, EISA 2007).
Martin Eberhard discusses the shortfalls of using Solar Energy as a key component in manufacturing a car. He believes that using fuel-cells to drive cars is a huge stretch in imagination. He finally notes that a mix of plug-in hybrid and gasoline is a viable idea for an interim solution for alternative energy sources to drive a car.
Application Of The Fourier Transform: Diffraction: Setup, Representation Of Electric Field, Approach Using Huyghens' Principle, Discussion Of The Phase Change Associated With Different Paths, Use Of The Fraunhofer Approximation, Aperture Function, Result; In General And For Single/ Double Slits
Efforts to promote solar water heating, photovoltaic electric generation, passive solar design. Discussion of light easements, building standards, and house value reassessments.
