How It Works

Mirror Layout - Image from patentPrometheus 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.

Thermocouples

As the ProSolarTec continues to improve its solar concentrating technology, the technologies used to measure and record data must also follow suit. Prometheus field tests currently use data acquisition software coupled with high-grade thermocouples to accurately measure temperatures of up to 8 different locations simultaneously. The testing has recently surpassed the upper limit of K-type thermocouples and in order to record these higher temperatures the Prometheus Team is now using platinum based R-type thermocouples. As the accuracy of the tests improves, more detailed fine-tuning can be executed on the prototypes, further increasing the success of the project's experiments.
