Here you will see two sites installed as a part of the "Brownfield to Brightfield Initiative in Oak Ridge, TN." Brownfield sites are government or industrial sites with restricted future use due to the presence or potential presence of hazardous substances, pollutants, or contaminants. This initiative has developed procedures to benefit from land that would otherwise remain unused while also promoting the use of renewable energy. There are no hazards when visiting this site as long as you stay outside fences and within mowed areas around the signs.
Note regarding directions to this site. If you take the Heritage Center Blvd. entrance from Highway 58, DO NOT take the first left turn. My navigator directed me that way and it is a dead end. Proceed North from Highway 58 and turn left at Victorious Blvd. Then turn left at Avenue M. There is a sign that says "Private Drive" at Avenue M. I checked with the landlord and learned the sign is no longer valid and public access is permitted here.
Note This cache is only available during daylight hours. Security personnel do not permit visitors outside their vehicle from sundown to sunup. During the day, this is not a problem.
The Oak Ridge Solar Farm consists of seven ground-mounted trackers that are 20 feet high and include 28-30 solar panels each. The trackers adjust themselves to capture the most sunlight and produce approximately 40 percent more energy than traditional ground-mounted systems. This array began operations in April 2013, cost $300,000, and can generate enough electricity to power about eight average American homes.
The Powerhouse Six solar array is to the east of the coordinates. This is a $1.8 million one-megawatt solar farm that uses 3,268 solar modules on five acres. Powerhouse 6 began operations in April 2015 and can generate enough electricity to power about 133 average-size homes per year.
You are in the former K-25 plant built during World War II as a part of the Manhattan Project. The K-25 plant enriched uranium by the gaseous diffusion method. The main building (now demolished) at this site was once the largest in the world. You could walk inside for a mile from one end to the other. When the process was in full operation it consumed 12% of all the electrical power generated in the country. Check out GC7B92A "TOP SECRET - KELLEX-25" to learn the interesting history of K-25. See the first solar array built here at GC5JXNJ "Brightfield 1".
This is a log-only cache so BYOP. Please replace as found.
