Solar Sausage
Figure 1: Cross-Sectional view of the Sausage
• Inflatable parabolic reflector in the shape of a sausage
• Made of a clear membrane and a Mylar reflective membrane

The System: Sun Tracking • Straps
o Glued to sides of Solar Sausage (shown in red)
o Crossed beneath Solar Sausageo Attached to weighted bar underneath
• Converts linear translation to rotational motion
• Direction of rotation of Solar Sausage dependent on bar motion o Ex. Moving bar to the right produces
counterclockwise rotation of Solar Sausage
