2. Problem Statement
Hyperbolic 3-D design replaces the control system that tracks the sunlight.
Combined effect of Conduction, Convection, and Radiation.
Use concentrated sunlight located at the focal point for maximum radiation absorption.

3. Motivation
Availability of fossil fuels is decreasing, leading to high demand for renewable
Reduce dependency on imported energy such as crude oil
Reduce environmental impact of fossil fuel consumption and harvesting

4. Previous Designs

5. Proposed Design Copper is a good heat absorber
Helical copper tube will be heated by conduction and convection
Concentrated sunlight is used to heat up the tubes by radiation
Glass helps retaining solar radiation inside the system to increase the efficiency

6. Alternative designs Use Reflected mirror or parabolic dish
Preheated water accelerates heating process
Provides higher steam temperature and pressure

7. Prototype System Description

8. Prototype Testing Absorption – with and without cover
Parabolic Bend Angles, Inclination Angle
Fluid Flow Rate
Shutoff Valve Locations

9. Cost Analysis Subject to change through the evolution of the project
