How It Works
Prometheus uses a two-stage method of solar concentration. The patented design has a 'primary' mirror that collects the sun rays and focuses them onto a 'secondary' mirror, which further focuses the light to a focal point. The adoption of two-stage geometry from that of a double curved lens is a relatively simple step that has allowed inexpensive but powerful collectors to be built. The method has a relatively small footprint, produces very high temperatures and is adaptable to a number of scales of size and materials of construction. The two-stage method provides a platform to cleanly and renewably power domestic and industrial heating and water purification.
Various collaborative projects have been conducted between the LIFE Prometheus team and Dalhousie University. Heat of fusion and ray tracing research, conducted by faculty and students of the Department of Mechanical Engineering, have been used to both measure the current power of Prometheus prototypes, and project the potential of prototypes in the future. The consensus of these research projects: Not only is this technology already incredibly powerful, but there is potential for even more growth.
