| EE293A will
start with a number of lectures on generalities about energy. We will
take a superficial look at the energy resources available to us and at
the rate in which we we are using them up. It will become clear that
before we run out of nonrenewable sources, we will encounter two major
problems: pollution and international political instability. These
problems are forcing a profound change into the the overall energy supply
strategy. Although a solution is well outlined at the moment, its implementation
will take decades, no matter what we do. To understand this, we will discuss
the Fisher-Pry penetration function. One of components of the solution
is the use of wind energy which, in the last few years has suddenly become
a major contributor. We will discuss aerodynamics and the theory of wind
turbines, with emphasis on on the fundamental theory of propeller type
machines. We will derive the Betz theorem and examine wake rotation effects.
At least as an interim application, internal combustion engines will continue
to be extremely popular. For them, fuels other that those of fossil origin
will grow rapidly in popularity. To understand this topic, we will refresh
your knowledge of thermodynamics and then discuss classic heat engines.
We will then be prepared for the description of biomass-derived fuels
such as ethanol and biodiesel. If time is available, we will bring up
the topic of ocean energy, one that appears to be more popular in Europe
than in he USA. |
