I’m assisting Oconomowoc High School with the aquaponics system in their greenhouse. So far we have set up two systems with 50 tilapia in one tank and 50 perch in a second tank. We are facing some challenges with our systems from the heat that is building when the outside temperature reaches 70 degrees or above. Tilapia need a water temperature of about 80 degrees, while perch need a water temperature of about 70 degrees. Our greenhouse reaches over 90 degrees and can see temperatures of 110. Before the weather gets too warm we need to find a way to keep the water cool enough for the fish to survive. Enter Travis. Travis is a second shift custodian at the high school and has significant experience in building aquaponics systems. I sat down with him over lunch the other day and was very impressed by his knowledge and experience. Travis has a high school diploma but has so much knowledge that I thought he had a college degree. Travis has had much hands on experience fabricating and problem solving over 150 aquaponic systems. I asked Travis if he had a degree. His response was that he just had a high school diploma but he picked up a lot of money and expertise doing side aquaponics jobs. He also has sought out many experts and used collaboration to build his knowledge.
Our discussion just reinforced my belief that we need more individuals with the ability to fabricate, and to use their hands to build projects that solve problems. I’m very impressed by his ability to think out of the box. After about an hour of talking, we had a solution to our overheating problem. It struck me that what Travis is doing is just the thing I want my students to do. Think out of the box, collaborate, seek expert advice, problem solve. The world could use more people like Travis!
