US BUREAU OF RECLAMATION PROCESS CERTIFICATION
The Bureau of Reclamation, along with others, wondered of the Suns River Still could really produce distillate at rates 4 - 5 times the classic solar still for the same area. In December, 2012, just a few days before the winter soltice - the worst solar day of the year - Suns River conducted a monitored test run at the Bureau's BGNDRF site in Alamogordo, NM, USA. The weak winter sun delivered only about half the energy as during our operations in August, but the still performed very well. Bureau engineers monitored the operation and we produced more than 2 liters/kWh. This even with the daytime temperature only about 55 degrees F (13 degrees C) and the nighttime low temperature 29 degrees F ( -1 degrees C). See the Bureau's certification of the Proof Run below.
