Sample Presentation from Baylor “AT” Symposium

The next slide is borrowed from one of the presentations at the Baylor AT Symposium:

CU Program in Engineering for Developing Communities

Dr. Bernard Amadei

Several additional slides from his AT Symposium presentation were also shown in this CEEC panel session.

CU Program in Engineering

for Developing Communities

Dr. Bernard AmadeiViewing the Developing World as the

Classroom of the 21st CenturyMission: A program dedicated to educating globally responsible students who can offer sustainable and appropriate technology solutions to the endemic problems faced by developing communities worldwide (including the US).

Issues of interest include water, sanitation, energy, shelter, health, food, jobs and capital for developing communities

Some Personal Observations

Appropriate Technology initiatives involve –

• certainty of unlimited possibilities• extend of projects already underway• cost of development and implementation

(+travel) • probability of implementation and/or

sustainability limitations (failures)• risk of community non-acceptance• likelihood of unintended consequences• payoff in great fulfillment (or disappointment)

Part 2 – Baylor’s New Masters Programs

“Master of Engineering Degree with Option in ‘Appropriate Technology for Developing

Countries’”

Baylor University

Baylor’s New Masters Programs

• During 2003-04, Baylor University initiated graduate work at the Masters level.

• Traditional research/thesis-oriented Master of Science programs are offered in:

Electrical and Computer Engineering,Mechanical Engineering, andBiomedical Engineering

• A more professionally oriented Master of Engineering program is also available.


Master of Engineering Requirements

Requires 33 credit hours (MS requires 30)

Project for 3-6 credit hours depending on the scope of project (MS thesis is 6 credits)

Course work of 27-30 credits– At least 15 credits must be taken in engineering– Up to 15 credits may be taken from the MBA

program in business


Master of Engineering Focus • Practice-oriented students (as distinct from

research-oriented students) who want to get advanced training in engineering and business at the MBA level

• Engineering classes the same as the Master of Science programs

• Distinction in the type of project selected (oriented more to application than discovery) and the opportunity to replace some engineering courses with business courses


Appropriate Technology EmphasisOne new senior elective/graduate course to be developed

Primary emphasis is in the project selected; for example,– Explore possibility of using coconut oil (possibly with

refining) as a substitute for diesel fuel (huge benefit for South Seas Islands such as Papua New Guinea)

– Design and deploy mini-hydroelectric equipment to be used in mountainous regions of developing countries with abundant rain fall

– Develop more energy efficient and safe cooking stoves

Increasing nut collection and maintaining coconut palms during high prices and; Virtually abandoning nut collection and ceasing to maintain coconut palms when prices are low.

This results in Farmers losing their prime source of cash income.

UTILIZATION OF COCONUT OIL AS A UTILIZATION OF COCONUT OIL AS A SUBSTITUTE FOR FOSSIL FUEL SUBSTITUTE FOR FOSSIL FUEL APPLICATIONSAPPLICATIONS

Similar to all other raw vegetable oils Similar to all other raw vegetable oils (soybean, rapeseed, linseed etc.), Coconut (soybean, rapeseed, linseed etc.), Coconut oil does have very similar properties to diesel oil does have very similar properties to diesel fuel:fuel:

In fact, the rebels in Bougainville Island have In fact, the rebels in Bougainville Island have been using the raw coconut oil as a source of been using the raw coconut oil as a source of fuel to generate power with minor fuel to generate power with minor modifications to their engines!modifications to their engines!Coconut oils have been used in Vanuatu to Coconut oils have been used in Vanuatu to power a vehicle.power a vehicle.

However, apart from engine fouling after However, apart from engine fouling after few hours of operation, like other raw few hours of operation, like other raw vegetable oils, coconut oil may also be used vegetable oils, coconut oil may also be used as a Fuel, but has the problem that it is too as a Fuel, but has the problem that it is too viscous in cold weather.viscous in cold weather.

IMPORTANT PHYSICAL AND CHEMICAL PROPERTIES OF VEGETABLE OIL

• Specific Energy – indication of the fuel’s energy released when it is burned. Coconut oil’s energy (42 MJ/kg) is more or less equivalent to Petroleum Diesel.

• Cetane Number (CN) – indication of the fuel’s willingness to ignite when it gets compressed. Coconut oil’s CN (60) is the highest.

• Viscosity – indication of the fuel’s ability to atomize in the injector system. Coconut oil’s viscosity is comparable with other oils but much more than petroleum diesel. Higher viscosity will cause poor volatilization of the fuel.

• Solidification Point – indication of the temperature at which the fuel will turn solid. Coconut oil’s solidification point (25°C) is at room temperature.

• Iodine Value (IV) – indication of the ability of the fuel to polymerize due to the fuels’ degree of bonds available. Coconut oil’s IV (10) is the lowest among all the fuel so it can be used directly in the engines without modification.

• Saponification Value (SV) – indication of the fuel’s ability to vaporize and atomize due to the fuels carbon chains. Coconut oil has the highest SV (268) which will ignite more quickly than others.

IMPROVING COCONUT OIL PROPERTIES

• Improvements to coconut oil properties & characteristics can be achieved by using the following methods:– Pyrolysis – Microemulsification– Dilution – Transesterification or Production of Biodiesel

• The coconut oil derivatives achieved by applying any of the above methods not only should approximate the properties and performance of the hydrocarbon-based diesel fuels but environmentally friendly!

CONCLUSIONS

•Pure coconut oil has been and can be used as a possible fuel substitute for diesel engines.

•Coconut oil derivatives should prove to be an excellent fuel substitute for diesel engines with improved performance characteristics.

•Similar to other vegetable oil derivatives, coconut oil derivates should provide an environmentally friendly fuel source.

•Coconut/copra prices should be stabilized or even increased.

•This should stop forcing farmers to abandon their coconut farms.

•It should improve the overall national economy.

•It should reduce reliance on imported petroleum diesel fuel.
