Energy Class PresentationsI offer you this selection list for the course presentations in HTML. This is more of a synopsis since the student RE Sessions list has the straight title and dates. I have linked all Power Point files even though some are just a placeholder. Observe the leading icons: construction, don't bother clicking; red ball, the link works to the page; yellow ball, content started; green ball, fairly final condition; blue ball, probably won't change.
I revised this presentations list to better match the sequence of the Godfrey Boyle Second Edition text that was used starting Spring 2005. The "a" and "b" presentations are usually given on the same day of class, but not always.
Click the session presentation title words for the quicker-loading html file or the preceding presentation number (e.g., 1.0) for the PowerPoint file. I post PowerPoint before html, but the html version will download faster on dial-up modem. The title page dates must agree with each other, or I may not have posted the latest version (please contact fleslie@fit.edu with the error and page name from the very bottom of the page in question). For your challenge, the actual class session number will often differ from the presentation number shown since the presentations have been rearranged to better match the current text book sequence.
1.9
A Renewable Energy
Introduction
This is an allegedly brief version for public outreach presentations. It was aimed at 30 minutes (assuming that there were no interrupting questions). So much to cover, so little time. There is a lot of diversity of issues in this subject, and one can only briefly touch on them.
Usually prepared and updated a few days prior to the start of the course, this session reviews some of the energy events in the news.
A discussion of the various combustion pollutants and their effects.
3.0 Climate Change Controversy, by Dr. Maul
Global warming? Overhead projector slides were used for this session and have not all been converted to digital files.
Fuel in general: heating, transportation, and electricity
5.0 Energy Conservation and Efficiency
The quickest way to reduce energy demands and costs
6.0 Energy
Return on Energy Investment and the "Emergy" Concept
How much energy is required to build an energy device or system?
Fuel or other heat to usable heat or electricity. Heat engines such as turbines or fueled engines are consumers of fossil fuels, but some run on concentrated sunlight or on temperature differences.
The primary fossil fuels: How do we get them and how do we use them? (8.0 & 9.0 are presented on the same day.)
Oil is really needed for moving vehicles and is wasted on fixed power plants. Natural gas has less pollution and is becoming the leading fuel for heating and power plants. "Naturally" (nudge, nudge), we are using more than we have and now import about 15% of our natural gas.
Controversial, but statistically clean: Can we keep it safe?

Florida may be "The Sunshine State", but we also have clouds and rain. Solar angles have great influence on the received solar energy at the ground.
Florida may claim to be "The Sunshine State", but we also have clouds diffusing or even blocking the sunlight. This session reviews the various methods of deriving solar heating energy. Solar cookers influence crowds at public events.
Electricity from the sun without much fuss. Photovoltaic modules provide electricity with little maintenance. A MPPT controller can wring the maximum possible energy out of what strikes the PV module.
Wind energy has the greatest cost/ benefit ratio of developing sources and is widely pursued. While a small percentage of total power, the rate of increase is high, ~40%/year.

Wind Energy - Dr. Lazarus
Dr. Lazarus presented "The Nature of the Wind", a detailed explanation of the source and characteristics of the wind.
Details of the general wind energy considerations
The mechanics of extracting the energy from the wind
Location of the wind farm, storage, control, reliability, availability
Power availability can be increased if a diesel or solar system augments the wind system (or vice versa). A marginal wind or solar system can subsidize the fueled system and reduce the cost or inconvenience of getting fuel. This is especially important when the fuel transportation cost is high.
Plants use solar energy and store carbon. Combustion releases the carbon in CO2, but other plants absorb it to grow, thus no net release into the atmosphere. Municipal waste streams (MSW) may be contaminated with heavy metals and produce pollution.
Brevard Biodiesel ppt Brevard Biodiesel html by Mr. Jay Wherley, March, 2009
Hydro is considered a conventional energy source since it has existed so long. Hydro is truly renewable solar as it is based upon water evaporation and precipitation. Small dams have often been removed, although others are being installed. The logical large stream dams on large rivers in the United States have long been established (ca. 1935). The phrase "new renewables" implies no old renewables and thus no hydro or wood-burning.
The Earth is hot inside, and heat can be extracted for our purposes. It's essentially renewable since the interior heat will likely outlive civilization. The surface ground and water absorbs solar energy, which is a differing form of geothermal energy from above rather than from below.

Ocean Wind and Wave Energy
This presentation was modified/presented by Dr. Maul, and we take occasional turns in updating it. Wind over the ocean is included as well as the water-borne energy.
Pipelines or electrical transmission lines; how do we move energy from the source to the load.
Intermittent energy sources need storage or back-up generators to provide energy at other times. Will the Hydrogen Economy be realized?
Some 54% of oil usage goes to transportation; hybrid vehicles will help extend the fuel. Airplanes, ships, trains. What are the vehicles of the future?
Alternative fuel vehicles, ethanol, and methanol.
No central power plant here! (Maybe) "Why can't we all get along?" and share power.
21.0
Economics, by Dr. Slotkin
Is renewable energy worth it? How can we tell? (Dr. Slotkin used slides that are not yet posted)
Comparison and selection of energy sources or mixes. Just a few of many tradeoff methods.
Laws, regulations, zoning, NIMBYs, and such. Local issues: (In 2003, Brevard County Commissioner Higgs used a discussion format with the students)
Where will energy issues focus in the future? What's important? Where do we go from here?
Another look at the possible future? What's important? Where do we go from here?
A brief review to aid in meeting the final test challenge. Refer to the full presentations above if you don't find what you are looking for here.
