Designed structural aerodynamic system for increased efficiency
Result: Shroud drastically increased power output and virtually eliminated noise and vibration

8.
Wind Turbine – Flow Simulations
For proof of concept: For shroud optimization:

9.
Wind Turbine – Ball bearings
Used SolidWorks to design ball bearings
1st iteration: needed to be permanently
superglued
2nd iteration: flanged for easy maintenance
