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.

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

Previous Designs

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

Alternative designs

Use Reflected mirror or parabolic dish

Preheated water accelerates heating process

Provides higher steam temperature and pressure
