2. Previously Defined design requirements Defined design requirements –Collaborated as group, using intuition and web-based research Proposed initial individual concepts Proposed initial individual concepts –Each researched distinct topics and presented to group

3. Design Requirements Provide 20W at 12V DC (continuous) Provide 20W at 12V DC (continuous) –40hr backup storage capability Utilizes reused components Utilizes reused components –At least 2 (i.e. battery, alternator, etc) Compact Compact –Ground footprint < 2 square meters

4. Individual Concepts Essential 3 major components to consider Essential 3 major components to consider

5. Currently Status: Status: –2 of 3 components decided on –Further feasibility research into engine (conversion) type –On schedule (no show-stoppers)

6. Future Development Decide on engine type Decide on engine type –Each member compiles pros/cons of each –Phill, Rachel further research in thermoacoustic –Paul further research on steam engine –Reconsider turbine Initial CAD model of trough and battery Initial CAD model of trough and battery –Derek research construction to roughly size parts –Kevin makes preliminary trough and battery model
