Cost Analysis

• Two Options to sell products to Boeing
• Purchase from Leopard's
• Manufacture ourselves
• Guaranteed 15,000 a month from Leopards
• Range between 1,097 and 19,720 profit if
  manufactured ourselves

22
Improvements

• SINCE 960? meets the set goal per generator
• Better Propeller, Bigger or more Aerodynamic
• Spring is too fast, needs lock mechanism
