Revolutionary Technologies Group C1 Nicholas Arch, Nicholas Fraser, Robert Huth, Patrick Noble, Michael Toomey Preliminary Design Review March 20, 2008

Last Week’s Action Items  Complete CAD model Add internal components to the base cylinder Show how the main shaft attaches to the system Display placement of guide lines which secure the wind turbine to the ground Describe in detail the blade setup  Finalize the blade manufacturing method Analyze vacuum forming plastic  Have to create mold and it is potentially expensive Bending of sheet metal  Heavy and not easily broken down or carried

Current Status of Concept Status of Design Beginning to manufacture the base unit, the blade mold, and start designing the electronics system Focus on: cost weight size
