Engineering Challenges in Algae Energy Engineering Challenges in Algae Energy What am I here for? To talk about Alternative energy Algae energy Engineering challenges in algae energy Alternative energy Alternative Energy Alternative energy refers to energy sources which are not based on the burning of fossil fuels or the splitting of atoms. The renewed interest in this field of study comes from the undesirable effects of pollution both from burning fossil fuels and from nuclear waste byproducts. Alternative energy Various forms of alternative energy Non renewable alternative energy Nuclear energy Nuclear energy Pros 1. Little Pollution 2. Reliability 3. Safety Cons 1. Meltdowns 2. Radiation 3. Waste Disposal Synfuel A gaseous, liquid, or solid fuel that does not occur naturally. Synthetic fuels can be made from coal, oil shale, or tar sands. Synfuel Pros- Produce gasoline, diesel or kerosene directly without the need for additional steps No need for new vehicles or convert engines to use a different fuel No need for new distribution network Less damaging to the environment Cons- Very expensive processIt contain only the one-third the energy content of solid coal. Oil shale A sedimentary rock containing solid, combustible organic matter in a mineral matrix. The organic matter, often called kerogen, is largely insoluble in petroleum solvents, but decomposes to yield oil when heated. Oil shale Pros Potential to produce a superior liquid-fuel product. less complex process low sulfur content and therefore less air pollution Cons Costs of fuel production from oil shale have not yet been fully evaluated. Disposal of the used shale Technology failures Renewable alternative energy Solar energy Solar energy PROS- Saves money Environmentally friendly Independent/ semi-independent Low/ no maintenance CONS- Potentially large areas required Not many places in the world have enough constant and intense su
