Abstract
CCAT volunteers and co-directors have an issue of being dirty upon the premises after working on the grounds. Thus came the opportunity to find a solution for this problem through the use of a solar shower.
Opportunity Definition
The objective of this project is to successfully design, build, and create a solar shower using an appropriate technology-based solution.
Background

Where: Campus Center for Appropriate Technology at Humboldt State University.
Who: For the co-directors and volunteers at CCAT.

Passive Solar Shower Basics There are two factors that affect the efficient of the water heater and they are solar irradiance and outdoor temperature. On a sunny days we see that the irradiance does not change much thus not changing the earth of the water. The outdoor temperature seems to have a greater effect on how warm the water gets.
Passive Solar Shower Concerns
If temperatures becomes freezing, there is possibility of water freezing within the system. Another consequence of freezing water includes the non movement of water through the system, which would need a pump to circulate the hot water. In recent years Humboldt has experienced below freezing temperatures. The water tank that is installed must be above the system and is relatively heavy, so we must make sure our frame structure is safe enough to withstand high winds or earthquakes. In the sites proposed, there is a thought of lack of sun exposure or even proper insulation. There is also possibility of blockage due to mineral build up or other gunk expose in the system. Proper drainage needs to ensure no erosion nor flooding in nearby areas.
