A heliostat is a reflective surface (mirror) which can be controlled by a computer to follow the sun as it moves through the sky. Its function is to concentrate the sun’s energy onto a target or receiver where it can be collected and stored.

The Solfast 2 Patent employs the toroidal heliostats developed by Heliosystems Pty Ltd to collect the solar energy. See http://heliosystems.com.au/path/
