In what direction
was the parabolic mirror positioned?
Once the mirror
was made and the kettle fixed in place, we needed a device to point
it into the sun. As the sun travels across the sky it takes different
angles from east to west and also different angles above the horizon.
We made a mount for the mirror that had one axis pointing parallel
to the axis of the rotation of the earth and the other set once
to the position of the sun.
All we had to
do was set up the mirror for the particular day and just turn the
apparatus around the one axis for the contraption to follow and
scan with the movement of the sun this is called an equatorial
mount. This allowed us to follow the sun and get the most energy
and efficiency from the system.
