Project Description


1. To produce a novel solar collector with comparable efficiency

and lower cost than commercially available models with

environmental sustainability in mind.

2. To demonstrate the energy savings in utilizing solar thermal

domestic hot water heating.

3. To provide a functional educational model to use in

instructing students and to mentor students in the construction

of their own solar thermal collectors.

4. To conduct a feasibility study of the local production and

incorporation of novel solar domestic hot water heaters into

Habit for Humanity houses.
