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.
First Iron Melt
LIFE Prometheus team members were successful in accomplishing their first iron melt using Prometheus solar technology on the 10th of July 2009. What started as a routine bronze melting procedure using the Beta-Gamma prototype yielded groundbreaking results. Unbeknownst to team members, while melting the bronze samples, the iron melting ladle became so hot that a portion of the ladle melted away. This unexpected landmark accomplishment offers further proof of the power of Prometheus technology.
