Matt's "$1K" Solar Water Heating System

This is Matt's version of the $1K type solar water
heating system.  Matt tried a few new things that might be just what you
are looking for.  One of Matt's innovations is what might be the worlds
first bicycle powered groove forming machine!

Matt is a very good craftsman, and
provides a wealth of interesting alternative ways of making the components.


Some of the unique features of Matt's

- A unique forming machine to
form the groove in the aluminum fins.

- A new method of attaching the fins to the copper tubes.


- A copper heat exchanger that
uses 6 parallel coils of 3/8 inch copper pipe.


- a galvanized metal collector


- A steel tank instead of the
EPDM lined plywood tank.

- Glass for glazing instead of polycarbonate.

Thanks very much to Matt for taking
the time to document this project!
